ColdBox 5.2.0 is a minor version update with lots of fixes, improvements and some new features not only to the ColdBox core but to LogBox and WireBox alike. Below are the major areas of improvement and the full release notes. To update your ColdBox installation just leverage CommandBox: update coldbox
The major areas of improvement for the ColdBox core where on tons of fixes, however there are some nice new features discussed below.
[COLDBOX-597] - Function addAsset
generate wrong link if asset path contains ".js"
[COLDBOX-668] - Make implicit views case sensitive by default for linux systems
[COLDBOX-677] - HTML HELPER - Fix a requirement for columnName
if column is defined
[COLDBOX-696] - Passing headers to `request
` breaks RoutingService when in test mode
[COLDBOX-724] - Add ENV
overload in detectEnvironment()
via ENVIRONMENT system setting/property
[COLDBOX-726] - setNextEvent does not exist in coldbox.system.web.Controller
[COLDBOX-727] - fail fast strong typed to boolean, update to allow closures
[COLDBOX-729] - getRenderData() in base test case was not looking at the right request collection
[COLDBOX-732] - Fail fast can't be turned off for original behavior
[COLDBOX-736] - Module mappings disappear when not unloading ColdBox in base test case
[COLDBOX-738] - Clear not working on string builders: Use setLength(0) since clear is not a method on StringBuilder
[COLDBOX-740] - When using group() operations with a handler and no explicit handler routing call added, route never registered the handler
[COLDBOX-722] - New global directive: autoMapModels
which if true, it will map all root models just like modules do.
This will allow root models to behave like modules where all models are registered automatically for you but with no namespace.
[COLDBOX-737] - toAction()
terminator is missing from the new router DSL
This terminator was missing from the new Routing DSL. This will allow you to build up routes that terminate at an action.
[COLDBOX-720] - Register config/Router.cfc
as an interceptor
The main application router and ALL module routers are now also interceptors.
[COLDBOX-730] - Implicitly pass args from renderLayout()
into the rendered views
[COLDBOX-739] - List modules which have already been processed when a module cannot be activated to help with debugging
[LOGBOX-29] - when using async option on FileAppender, nothing logs, well now it does!
[LOGBOX-31] - Add defaultValue
arguments to getProperty()
methods on abstract appenders
[LOGBOX-30] - Leave off text "ExtraInfo: "
from console appender if empty string
[WIREBOX-76] - Virtual inheritance not injecting generic getters and setters correctly on target objects
[WIREBOX-77] - Virtual inheritance not inheriting init
from super class
[WIREBOX-51] - Add method to binder to override alias of current mapping, by passing the current mapping to the influencer closure
[WIREBOX-75] - Don't exclude path in parent mapping destinations
[WIREBOX-78] - Simplify error message for missing dependency to be human readable
ColdBox 5.6.0 is a minor version update with lots of fixes, improvements, performance enhancements and some nice new features. Below are the major areas of improvement and the full release notes. To update ColdBox or any of the standalone libraries just leverage CommandBox:
update coldbox
update logbox
update wirebox
update cachebox
We had two specific tickets that have resulted in extreme performance improvements for ALL ColdBox requests. You will feel and see the difference:
[] - Event Handler Bean: Single instance per handler action for major performance improvements
This ticket was contributed by Dom Watson () one of the lead engineers of the amazing PresideCMS project built on top of ColdBox. We worked together to avoid the creation of handler beans on each runnable event. We now cache each event handler bean representation which results in an extreme boost in performance. Thanks Dom!
[] - Remove afterInstanceAutowire interceptor in handlerService as afterHandlerCreation is now officially removed.
Thanks to our local mad scientist Brad Wood, he reported that the handler services still listened to ALL CFC creations in an application in order to relay an afterHandlerCreation
interception point from the good 'ol 2.6 days. This has been finally removed and boom, another big boost in performance!
We have enhanced the bug reporting templates to include much more information when dealing with exceptions:
Show SQL error details on Adobe CF
Current route, params and debug info
Contributing module for the current routed URL
Thanks to our very own Eric Peterson, you can now merge HTTP verbs on the same route pattern, which you could not do before:
[] - ModuleService to add default route doesn't work correctly
[] - Fix default bug report to show SQL error detail for adobe SQL exceptions
[] - When doing package resolving if you are in a module it still tries to resolve a module
[] - Error in HTML helper WRAPPERATTRS doesn't exist in argument scope
[] - Include the colon for non 80 or 443 port numbers #419 in github
[] - Allow merging of HTTP verbs when doing separate verbs for the same route
[] - Update cfconfig to use env variables instead of inline mixins, modernizeOrDie
[] - Add more current route information to the BugReport.cfm template
[] - Ability for bug reports and app to know which module contributed the incoming URL route.
[] - Use of .keyExists() can needlessly use memory in requests, suggest StructKeyExists() instead
[] - Event Handler Bean: Single instance per handler action for major performance improvements
[] - HandlerService.cfc$newHandler(): declares variables that are never used
[] - Remove afterInstanceAutowire interceptor in handlerService as afterHandlerCreation is now officially removed.
[] - AbstractCacheProvider.getOrSet(): local var unscoped when checking if null
This is a patch release for ColdBox
[COLDBOX-715] - Elvis operator inconsistencies on Adobe Engines, please Adobe, patch the engines and fix your compiler!
[COLDBOX-237] - Some HTMLHelper method still need escaping as certain values should never be HTML
[COLDBOX-716] - determine session/client state via CF getApplicationMetadata() instead of isDefined() to avoid load issues for flash ram
[COLDBOX-717] - RemotingUtil converted to cfscript #367
ColdBox 5.3.0 is a minor version update with lots of fixes, improvements, performance enhancements and some nice new features. Below are the major areas of improvement and the full release notes. To update your ColdBox installation just leverage CommandBox: update coldbox
[COLDBOX-741] - Defining UDF as COLDBOX_FAIL_FAST no longer returns false
[COLDBOX-750] - Fixed typo(s) in call of function prePend() on routing
[COLDBOX-752] - base url not eliminating double slashes
[COLDBOX-756] - Setter for valid extensions is setting the wrong variable
[COLDBOX-759] - Cleanup the with closure on group routing to avoid leakage
[COLDBOX-753] - Add new flag to router: multiDomainDiscovery
that can be turned on/off
[COLDBOX-742] - Add trimming to asset loader to avoid spaces on links
[COLDBOX-744] - InterceptorState + EventPool uses syncrhonizedMap that has locking issues: refactor to avoid these issues
[COLDBOX-754] - set initiated bit for ColdBox after modules are activated
[COLDBOX-760] - Performance improvements for interception registrations and discovery
[LOGBOX-32] - Add test and fix for adding a LogBox category after the fact
[WIREBOX-79] - Account for leading slashes in mapDirectory()
[WIREBOX-80] - Throw a nicer DSL error if ColdBox is not linked
[WIREBOX-81] - Performance improvements for the construction of transients
ColdBox 5.5.0 is a minor version update with lots of fixes, improvements, performance enhancements and some nice new features. Below are the major areas of improvement and the full release notes. To update your ColdBox installation just leverage CommandBox:
update coldbox
update logbox
update wirebox
update cachebox
The major libraries updated in this release are ColdBox MVC and WireBox.
If you are using annotations for component aliases you will have to tell WireBox explicitly to process those mappings. As by default, we no longer process mappings on startup.
This release is a big performance boost for two areas of operation: modules, and models. The Module Service has been completely revised to make it as fast as possible when registering and activating modules. If you have an extensive usage of modules, you will feel the difference when booting up or re-initing the framework.
The other area is the inspection of models that has been lazy evaluated. This allows for faster bootups and reinits as models are only inspected on demand or when explicitly marked.
Our environment functions have now been added to the Framework SuperType and thus all objects in the ColdBox eco-system receive it:
getEnv(), getSystemSetting() and getSystemProperty()
As resources have become more mainstream in ColdBox, we now give you the ability to choose the URL pattern you want to attach to the resource. This allows you to create a-la-carte resource patterns and also allow you to nest resources via patterns.
[COLDBOX-786] - HTMLHelper typo on getSetting
call via elixirpath()
[COLDBOX-788] - Private method in handler is accessible from public ( direct link )
[COLDBOX-783] - New module directive: autoProcessModels
which defaults to false to defer to lazy processing of models
[COLDBOX-789] - Added getEnv(), getSystemSetting() and getSystemProperty()
to super type for easier environment setting retrievals
[COLDBOX-790] - Added much more logging and info when booting up the Module Service
[COLDBOX-791] - buildLink(), relocate()
now will translate raw : to / in URL
with appropriate module entry points thanks to richard herbert
[COLDBOX-792] - Allow nested resources and the ability for custom URL patterns for resources
[COLDBOX-782] - Add TestBox 3 and code coverage to the core
[COLDBOX-785] - Module service performance optimizations for module activations.
[COLDBOX-787] - Update RequestContext.cfc getFullUrl()
to include port number
[WIREBOX-84] - Remove auto processing of all mappings defer to lazy loading
[WIREBOX-85] - MapDirectory
new boolean argument process
which defers to false, if true, the mappings will be auto processed
[WIREBOX-86] - New binder method: process()
if chained from a mapping, it will process the mapping's metadata automatically.
[WIREBOX-87] - AOP debug logging as serialized CFCs which clogs log files
ColdBox 5.4.0 is a minor version update with lots of fixes, improvements, performance enhancements and some nice new features. Below are the major areas of improvement and the full release notes. To update your ColdBox installation just leverage CommandBox:
update coldbox
update logbox
update wirebox
update cachebox
In our initiative to make all Modules sharable between ColdBox, CommandBox and whatever other boxes we make in the future. We created the box
alias for injections. In our case any injection with the prefix coldbox
can be used as box
We have created a new internal runner called runRoute()
which is similar to runEvent()
but it allows you to abstract your events by leveraging named routes. So just like you can create links based on named routes and params, you can execute named routes and params as well internally via runRoute()
This should have been a major release on its own. The entire CacheBox framework was re-written in script and modernized from top to bottom. We removed all implicit variable access which gave us huge performance boosts and we streamlined all operations with modern techniques. The results are great and our maintenance will be much less in the future. A part from those optimizations we managed to add a few nice items:
Adobe 2018 certified
New setting resetTimeoutOnAccess
which allows you to simulate session scopes on any CacheBox cache. Every time a get()
operation is done, that item's timeout will be reset.
All cache providers get some multi function goodness: setMulti(), getMulti(), lookupMulti(), clearMulti(),getCachedObjectMetadataMulti()
There are two major improvements we did with LogBox in this release:
1) The file locking operations on file appenders have been streamlined to avoid high i/o operations.
2) The console appender uses an asynchronous streaming technique which makes it extremely efficient and fast.
[COLDBOX-556] - prePostExempt
doesn't skip around advices
[COLDBOX-755] - Core interceptors in coldbox.cfc do not listen or register custom interception points that are contributed by modules
[COLDBOX-761] - invalidEventHandler
gets in to an infinite loop when the invalidEventHandler
isn't a full event
[COLDBOX-766] - ColdBox shutdown errors onApplicationEnd
due to lack of application scope
[COLDBOX-770] - Use of event.sendFile
delivers a file with single quotes in the name
[COLDBOX-773] - Remove default defaultValue as it never will throw an exception if missing on requestcontext on getHTTPHeader()
[COLDBOX-765] - Update all elixir methods to match new version
[COLDBOX-771] - Add Elixir version 3 path methods
[COLDBOX-775] - Added `:`
as a delimiter for the route()
method when using modules to be consistent with run event
[COLDBOX-776] - new runner: runRoute()
that allows you to run routes internally with param passing
[COLDBOX-767] - Change "module already registered" from warn to debug
[COLDBOX-774] - Introduce generic "box" namespace for Wirebox injections
[CACHEBOX-46] - CacheboxProvider metadata and stores: use CFML functions on java hash maps breaks concurrency
[CACHEBOX-50] - getOrSet() provider method doesn't work with full null support
[CACHEBOX-52] - getQuiet(), clearQuiet(), getSize(), clearAll(), expireAll() broken in acf providers
[CACHEBOX-48] - New setting: `resetTimeoutOnAccess` to allow the ability to reset timeout access for entries
[CACHEBOX-49] - Global script conversion and code optimizations
[CACHEBOX-53] - lookup operations on ACF providers updated to leverage cacheIdExists() improves operation by over 50x
[CACHEBOX-54] - setMulti(), getMulti(), lookupMulti(), clearMulti(),getCachedObjectMetadataMulti() is now available on all cache providers
[CACHEBOX-47] - Increased timeout on `getOrSet` lock
[CACHEBOX-51] - Consolidated usages of the abstract cache provider to all providers to avoid redundancy
[WIREBOX-82] - builder.toVirtualInheritance()
: scoping issues
[WIREBOX-83] - When using sandbox security, and using a provider DSL the file existence checks blow up
[LOGBOX-34] - Console appender completely rewritten to support asynchronous streaming
[LOGBOX-33] - Improve file exists usage on file appenders to avoid i/o operations
ColdBox 5.0.0 is a major release for the ColdBox MVC platform. It has been long standing as we have been learning so much especially around containerization and portability. This release has over 70 key issues addressed from new features, improvements and bug fixes. So let's begin our ColdBox 5 adventure.
All internal libraries now have a standard version according to the major ColdBox release of 5.0.0. Further releases of WireBox, CacheBox and LogBox will adhere to the unified version.
It is also yet another source code reduction due to the dropping of support for the following CFML Engines:
Adobe ColdFusion 9
Adobe ColdFusion 10
That's right, you will need Adobe ColdFusion 11+ or Lucee 4.5+ in order to work with ColdBox 5.
We have fully automated all build processes with ColdBox 5 to include CommandBox and TestBox testing, Travis integration and a fully automated test suite that executes against ALL supported CFML engines. Our code coverage has increased dramatically due to this work. We discovered engine bugs that must have plagued our users for years. YAY for testing!
As we update core files we keep optimizing the source code and migrating to full cfscript. This migration has allowed us to optimize very old code into modern times with significant performance gains. We have also moved from internal Java reflection to get file information to native CFML functions since now all engines support it. Just this alone has improved vanilla requests tremendously.
WireBox object creation and manipulation has also increased due to new locking strategies in our Mixer Util. You will especially see the difference when creating many transient objects.
Thanks to the community we have now full null
support for the Lucee CFML engine and up-coming Adobe 2018.
The core framework has been revised with a fine tooth comb to provide better exception messages, better helpful messages and also the ability to intercept exceptions at the framework level via normal exception handlers. You will also see that ColdBox can detect response headers now and make sure it can avoid caching exceptions when event caching is turned on. The appropriate status code will now be reported.
You will also find in the log files attempts to reinit the framework with invalid or missing passwords.
ColdBox introduces two new methods that are available for your ColdBox.cfc
and your ModuleConfig.cfc
objects:
getSystemProperty( name, defaultValue )
- Retrieve a Java System property
getSystemSetting( name, defaultValue )
- Discover an environment variable either by searching system properties first and then system environment variables second.
Hint These methods are also found in the ColdBox core utility object:
coldbox.system.core.util.Util
which can be injected anywhere it is needed.
These methods will allow you to interact with docker environment variables and override settings, add new settings, and much more.
We continue to innovate in the Hierarchical MVC (HMVC) design of ColdBox by fine-tuning the modular services and interactions. Here are the major updates to modules in ColdBox 5.
All module interceptors are now namespaced to avoid name conflicts with other modules.
New modules injected variable: coldboxVersion
to be able to quickly detect what version of ColdBox they are running under. This will allow you to create modules that can respond to multiple ColdBox versions.
All modules have had a URL entry point since the beginning: this.entryPoint = "/route"
. This entry point is registered in the URL mappings to allow for a unique URL pattern to exist for specific modules. That is great! However, in modern times and with the amount of API centric applications that we are building, we wanted to introduce an easier way to build resource centric APIs.
What if our resource URLs could match by convention our module inceptions? Well, with the new inherited entry points, you can do just that. By leveraging HMVC and module inception you can now create automatic URL nesting schemas.
You can turn this on just by adding the following flag in your ModuleConfig.cfc
:
When the module is registered it will recurse its parent tree and discover all parent entry points and assemble the entry point accordingly. Let's see an example. We are working on an API and we want to create the following URL resource: /api/v1/users
. We can leverage HVMC and create the following modular structure:
This models our URL resource modularly. We can now go into each of the module's ModuleConfig
and add only the appropriate URL pattern and turn on inherit entry point.
This feature will not only help you identify API routing, but help you build with modularity in mind. You will also find a new method in the request context called getModuleEntryPoint()
to retrieve a modules inherited entry point, which is great for URL building.
You can now listen to more events of the module life-cycle:
preModuleRegistration
- before each module is registered
postModuleRegistration
- after each module is registered
afterModuleRegistrations
- This will fire when all modules have been registered. This is great if you want modules to dynamically depend on each other.
afterModuleActivations
- This will fire when all modules have been succesfully activated. Great for caching updates, announcements, etc.
We have now added the modules_app
convention for all module inceptions.
If you create a module where there is a model with the same name, then we will automatically map it in Wirebox as @modulename
.
This is great for 1 model modules.
We continue to push forward in making ColdBox the best RESTFul framework for ColdFusion (CFML). In ColdBox 5 we have great new additions for both routing and rendering.
The SES interceptor now has a boolean flag to denote if rewrites are turned on/off and you will no longer set a base URL. We will automatically detect the base URLs according to multi-domain hosting. Meaning you can out of the box create multi-tenant applications with ease. We will also be adding subdomain routing in our final release.
This has been a long-time coming to ColdBox and I can't believe we had never added this before. Well, named routes are here, finally!
If you have used other frameworks in other languages, they allow you to name your routes so you can build links to them in an easier manner. We have done just the same. The addRoute()
method accepts the name
parameter and we have extended the request context with some new methods:
getCurrentRouteName()
- Gives you the name of the current route, if any
route()
- Allows you to build URLs according to named routes
Define the Route
Build Links
The route
method signature can be seen below:
In ColdBox 5, you can register resourceful routes to provide automatic mappings between HTTP verbs and URLs to event handlers and actions by convention. By convention, all resources map to a handler with the same name or they can be customized if needed. This allows for a standardized convention when building routed applications.
You will now have a new resources()
method in the SES interceptor or a resources
struct in your modules. Yes, all modules can have their own resourceful routes as well.
This single resource declaration will create all the necessary variations of URL patterns and HTTP Verbs to actions to handle the resource. It will even create named routes for you.
For in-depth usage of the resources()
method, let's investigate the API Signature:
We have also done several updates for event executions, event caching and overall MVC operations:
You can now return the event
object from event handlers and the framework will not fail. It will be ignored.
setNextEvent()
is now deprecated in favor of a relocate()
method.
Request context has a getOnly( keys, private=false )
method to allow for retrieval of certain keys only from the public or private request contexts. Great for functional programming.
You can now leverage the cache suffix property in handlers to be declared as a closure so it can be evaluated at runtime instead of a static prefix.
With this ability you can enable dynamic cache suffixes according to runtime environments on a per user basis.
You can now add a cacheProvider
annotation to your cache enabled functions and decide to which CacheBox provider the output will be cached too instead of the default provider of template
:
We have also done tremendous updates to the rendering engines in ColdBox 5, especially for RESTFul responses and content negotiation.
ColdBox now detects the rc.format
not only to incoming URL extensions, but also via the Accept
Header as content-negotiation.
New interception point afterRenderInit
which will allow you to add your own injections to the main ColdBox renderer and modify the renderer at runtime.
The request context can now deliver files to users via our sendFile()
method.
JSON is the native response now for event handlers that return complex variables.
That's it! If you return a complex variable from an event handler, ColdBox will convert it to JSON for you automatically. We will even inspect the return object and if it has a $renderdata()
method, we will call it for you and return your very own marshalled data! But there's more. You can add a renderData
annotation to your action and add any valid renderdata()
type and it will return it accordingly.
You can even add a default response type by adding the renderdata
annotation to the component
construct:
We have introduced the concept of named rendering regions with ColdBox 5. As we increase the reuse of views and create many self-sufficient views or widgets, we end up with setView()
or renderView()
method calls that expose too much logic, location, parameters, etc. With named regions, we can actually abstract or describe how a region should be rendered and then render it when we need it via a name.
Definition
Rendering
Here are some of the major updates for integration testing with ColdBox and TestBox:
Reset the response when calling setup()
in integration testing to avoid duplicate headers within same request executions.
Base test case doesn't allow for inherited annotations. It now does since we moved the testing life-cycle methods to be annotation based instead of by name.
Added dynamic methods getRenderData()
and getStatusCode()
helpers to the request context upon execute()
execution. This will allow you a shorthand approach to getting response status codes and response rendering data struct.

ColdBox 5.1.0 is a minor version update with lots of fixes, improvements and some new features. Below are the major areas of improvement and the full release notes. To update your ColdBox installation just leverage CommandBox: update coldbox
The event caching cleanup and clearing methods did not work when using granular query strings. This has now been resolved and optimized.
If you are working with any modern JavaScript framework, this feature is for you. ColdBox on any incoming request will inspect the HTTP Body content and if the payload is JSON, it will deserialize it for you and if it is a structure/JS object, it will append itself to the request collection for you. So if we have the following incoming payload:
The request collection will have 3 keys for name, type and data according to their native CFML type.
The flash scope needed a way to get all of its name-value pair elements in one shot, you can now with the getAll()
method.
The HTML helper has been completely rewritten in 5.1 into script notation, optimized for performance and security. All HTML output is now XSS encoded for attributes and tag content.
You can now declare a view and directory helper and ColdBox will use them both instead of always picking the view helper only. The order of inclusion is:
directory helper
view helper
view
This is a nice feature that will give your applications stability when doing deployments or production reinits. We have added a new application variable flag: application.fwReinit which is set to true when the framework is reinitializing and false when it completes. We have also added a new directive called COLDBOX_FAIL_FAST which defaults to true.
If fail fast is activated, the framework will present a nice message to users that the application is not yet available instead of holding them in a queue waiting for the reinit or application load to finish. This fail fast will release your traffic queue and produce less timeouts and failures.
The fail fast directive can also be a closure. Then we will execute your closure and you can do whatever you like within it to advice your users' about the reinit. Below you can see what happens with the fail fast code.
The major compatibility issues will be covered as well as how to smoothly upgrade to this release from previous ColdBox versions. You can also check out the guide to give you a full overview of the changes.
event.getCurrentHandler()
returns different resultsIn ColdBox 4, calling getCurrentHandler()
would return the module if it existed:
In ColdBox 5, we correctly remove the module name so it can be retrieved via getCurrentModule()
instead.
setNextEvent()
deprecated in favor of relocate()
The setNextEvent()
method has been renamed to relocate()
to better adjust to modern times. This deprecation will be removed in future versions of ColdBox.
The modules autoReload
flag has been deprecated. This causes more headaches than anything. If you want changes reflected, reinit the framework.
onInvalidEvent
renamed to invalidEventHandler
The ColdBox construct setting onInvalidEvent
has been renamed now to invalidEventHandler
. This will be removed in future versions of ColdBox.
setAutoReload()
RemovedThe setAutoReload()
flag in the SES interceptor has been removed. It is evil I tell you. If you want your routing to be re-read, then reinit the framework.
The buildLink()
method had the argument linkTo
to denote the event or route to link to. This was verbose, so we shortened it to to
:
Railo support dropped. Any classes that started with the word Railo
need to be changed to Lucee
especially on the CacheBox providers.
ColdFusion 9-10 support has been dropped. Adobe doesn't support them anymore, so neither do we.
The datasources
configuration setting directive has been dropped in favor of just leveraging the settings
directive. Just move your datasource metadata into the settings
struct and reference it using the settings DSL.
Previous
New
The WireBox interface: coldbox.system.ioc.dsl.IDSLBuilder
has changed in ColdBox 5, so if you are implementing your own DSLs, then you must update it like so:
In ColdBox 5 we removed the output attribute:
The string buffer has been updated in order to become thread safe and there are several methods that have been deprecated. Instead of using appendToBuffer()
you need to use the buffer
argument.

This is a patch release for ColdBox.
[] - regression onmissingmethod on html helper method was public and changed to private
[] - viewModule logic was not working at all yet again.
[] - Remove setting throwOnInvalidInterceptionStates, makes no sense anymore
[] - Moved order of event manager states the injector provides to a ColdBox app so the binder can listen on itself
This is a patch release for ColdBox
[] - HTML helper cannot add fontawesome icons in button due to XSS enabled by default
[] - ColdBox shutdown code that uses CF mappings for modules fails on fwreinit
[] - addAsset throw error when called from handlers
[] - Too many issues when encoding by default for HTML Helper, revert to non-encoded and provide ways to encode globally and a-la-carte
[] - Framework setting for the automatic deserialization of JSON payloads to the RC: jsonPayloadToRC
The automatic JSON to request collection feature defaults now to false to avoid backwards compatibility. You can easily turn it on via the setting: coldbox.jsonPayloadToRC
The HTML Helper has been migrated to an internal module in this release. It allows you to configure it via the following configuration settings in your ColdBox.cfc
.
You can also now inject the HTML helper anywhere using it's injection DSL Shortcut of @HTMLHelper
ColdBox provides you with a nice method for generating links between events by leveraging an object called event
that is accessible in all of your layouts/views and event handlers. This event
object is called behind the scenes the request context object, which models the incoming request and even contains all of your incoming FORM
and URL
variables in a structure called rc
.
Tip: You will use the event object to set views, set layouts, set HTTP headers, read HTTP headers, convert data to other types (json,xml,pdf), and much more.
The method in the request context that builds links is called: buildLink()
. Here are some of the arguments you can use:
Edit the views/virtual/hello.cfm
page and wrap the content in a cfoutput
and create a link to the main ColdBox event, which by convention is main.index
.
This code will generate a link to the main.index
event in a search engine safe manner and in SSL detection mode. Go execute the event: http://localhost:{port}/virtual/hello
and click on the generated URL, you will now be navigating to the default event /main/index
. This technique will also apply to FORM submissions:
For extra credit try to use more of the buildLink
arguments.
ColdBox allows you to manipulate the incoming URL so you can create robust URL strategies especially for RESTFul services. This is all done by convention and you can configure it via the application router: config/Router.cfc
for more granular control.
Out of the box we provide you with convention based routing that maps the URL to modules/folders/handlers and actions.
route( "/:handler/:action" ).end()
We have now seen how to execute events via nice URLs. Behind the scenes, ColdBox translates the URL into an executable event string just like if you were using a normal URL string:
/main/index
-> ?event=main.index
/virtual/hello
-> ?event=virtual.hello
/admin/users/list
-> ?event=admin.users.list
/handler/action/name/value
-> ?event=handler.action&name=value
/handler/action/name
-> ?event=handler.action&name=
By convention, any name-value pairs detected after an event variable will be treated as an incoming URL
variables. If there is no pair, then the value will be an empty string.
Tip: By default the ColdBox application templates are using full URL rewrites. If your web server does not support them, then open the config/Router.cfc
and change the full rewrites method to false: setFullRewrites( false ).
This guide has been designed to get you started with ColdBox in fewer than 60 minutes. We will take you by the hand and help you build a RESTFul application in 60 minutes or fewer. After you complete this guide, we encourage you to move on to the and then to the other guides in this book.

Welcome to the world of ColdBox!
We are excited you are taking this development journey with us. Before we get started with ColdBox let's install CommandBox CLI, which will allow you to install/uninstall dependencies, start servers, have a REPL tool and much more.
ColdBox has the following supported IDE Tools:
Sublime -
VSCode -
CFBuilder -
Note : However, you can use your own ColdFusion server setup as you see fit. We use CommandBox as everything is scriptable and fast!
No Java Runtime (30mb)
Embedded Runtime (80mb)
Once you download and expand CommandBox you will have the box.exe
or box
binary, which you can place in your Windows Path or *Unix /usr/bin
folder to have it available system wide. Then just open the binary and CommandBox will unpack itself your user's directory: {User}/.CommandBox
. This happens only once and the next thing you know, you are in the CommandBox interactive shell!
We will be able to execute a-la-carte commands from our command line or go into the interactive shell for multiple commands. We recommend the interactive shell as it is faster and can remain open in your project root.
All examples in this book are based on the fact of having an interactive shell open.
To get started open the CommandBox binary or enter the shell by typing box
in your terminal or console. Then let's create a new folder and install ColdBox into a directory.
You can also install the latest bleeding edge version by using the coldbox@be
slug instead, or any previous version.
To uninstall ColdBox from this application folder just type uninstall coldbox
.
To update ColdBox from a previous version, just type update coldbox

CommandBox comes with a coldbox create app
command that can enable you to create application skeletons using one of our official skeletons or :
Advanced : A tag based advanced template
AdvancedScript (default
): A script based advanced template
elixir : A ColdBox Elixir based template
ElixirBower : A ColdBox Elixir + Bower based template
ElixirVueJS : A ColdBox Elixir + Vue.js based template
rest: A RESTFul services template
rest-hmvc: A RESTFul service built with modules
Simple : A traditional simple template
SuperSimple : The bare-bones template
You can find all our template skeletons here:
So let's create our first app using the default template skeleton AdvancedScript:
This will scaffold the application and also install ColdBox for you. The following folders/files are generated for you:
Now let's start a server so we can see our application running:
If you are using CommandBox 3 and below, you will be using a Lucee 4.5 Server.
This command will start a server with URL rewrites enabled, open a web browser for you and execute the index.cfm
which in turn executes the default event by convention in a ColdBox application: main.index
.
Tip: ColdBox Events map to handlers (cfc) and appropriate actions (functions)
That's it, you have just created your first application. Hooray, onward!
Tip: Type coldbox create app help
to get help on all the options for creating ColdBox applications.
ColdBox is a conventions based framework. The location of files and functions matter. Since we scaffolded our first application, let's write down in a table below with the different conventions that exist in ColdBox.
What is the common denominator in all the conventions? That they are all optional.
There will be times when you make configuration or code changes that are not reflected immediately in the application due to caching. You can tell the framework to _reinit _or restart the application for you via the URL by leveraging the special URL variable fwreinit
.
You can also use CommandBox to reinit the application:
Now let's create our first controller, which in ColdBox is called Event Handler. Let's go to CommandBox again:
This will generate the following files:
A new handler called hello.cfc
inside of the handlers
folder
A view called index.cfm
in the views/hello
folder
An integration test at tests/specs/integration/helloTest.cfc
.
Now go to your browser and the following URL to execute the generated event:
You will now see a big hello.index
outputted to the screen. You have now created your first handler and view combination.
Let's check out the handler code:
As you can see, a handler is a simple CFC with functions on them. Each function maps to an action that is executed via the URL. The default action in ColdBox is index()
which receives three arguments:
event
- An object that models and is used to work with the current request
rc
- A struct that contains both URL/FORM
variables (unsafe data)
prc
- A secondary struct that is private only settable from within your application (safe data)
The event object is used for many things, in the case of this function we are calling a setView()
method which tells the framework what view to render to the user once execution of the action terminates.
Tip: The view is not rendered in line 7, but rendered after the execution of the action by the framework.
Did you detect a convention here?
The sections in the URL are the same as the name of the event handler CFC (hello.cfc
) and method that was generated index()
. By convention, this is how you execute events in ColdBox by leveraging the following URL pattern that matches the name of a handler and action function.
You can also nest handlers into folders and you can also pass the name of the folder(s) as well.
If no action
is defined in the URL then the default action of index
will be used.
All of this URL magic happens thanks to the URL mappings capabilities in ColdBox. By convention, you can write beautiful URLs that are RESTFul and by convention. You can also extend them and create more expressive URL Mappings by leveraging the config/Router.cfc
which is your application router.
Now let's create a virtual event, which is basically just a view we want to execute with no event handler controller needed. This is a great way to incorporate non-mvc files into ColdBox, baby steps!
Open the view now (/views/virtual/hello.cfm
) and add the following:
Then go execute the virtual event:
You will get the Hello From ColdBox Land!
displayed! This is a great way to create tests or even bring in legacy/procedural templates into an MVC framework.
Shalom Children’s Home () is one of the ministries that is dear to our hearts located in El Salvador. During the 12 year civil war that ended in 1990, many children were left orphaned or abandoned by parents who fled El Salvador. The Benners saw the need to help these children and received 13 children in 1982. Little by little, more children came on their own, churches and the government brought children to them for care, and the Shalom Children’s Home was founded.

The first step in our journey is to CommandBox. is a ColdFusion (CFML) Command Line Interface (CLI), REPL, Package Manager and Embedded Server. We will be using CommandBox for almost every excercise in this book and it will also allow you to get up and running with ColdFusion and ColdBox in a much speedier manner.
You can download CommandBox from the official site: and install in your preferred Operating System (Windows, Mac, *unix). CommandBox comes in two flavors:
So make sure you choose your desired installation path and follow the instructions here:
CommandBox will resolve coldbox
from ForgeBox (), use the latest version available, download and install it in this folder alongside a box.json
file which represents your application package.
That's it. CommandBox can now track this version of ColdBox for you in this directory. In the we will scaffold a ColdBox application using an application template.
You can find many scaffolding templates for ColdBox in our Github organization:

Out of the box, ColdBox gives you all the RESTFul capabilities you will need to create robust and scalable RESTFul services. Let's add some RESTFul capabilities to our contact listing we created in the previous section.
Tip: You can find much more information about building ColdBox RESTFul services in our full docs.
If you know beforehand what type of format you will be responding with, you can leverage ColdBox 5's auto-marshalling in your handlers. By default, ColdBox detects any return value from handlers and if they are complex it will convert them to JSON automatically for you:
That's it! ColdBox detects the array and automatically serializes it to JSON. Easy Peasy!
If you want your incoming JSON requestbody to be handled the same as FORM and URL variables you can enable coldbox.jsonPayloadToRC = true
in your coldbox config. See releasenotes 5.1.0
and 5.1.2 for details.
The request context object has a special function called renderData()
that can take any type of data and marshall it for you to other formats like xml, json, wddx, pdf, text, html
or your own type.
Tip: You can find more information at the API Docs for renderData()
here http://apidocs.ortussolutions.com/coldbox/current/index.html?coldbox/system/web/context/RequestContext.html#renderData()
So let's open the handlers/contacts.cfc
and add to our current code:
We have added the following line:
This tells ColdBox to render the contacts data in 4 formats: xml, json, pdf and html. WOW! So how would you trigger each format? Via the URL of course.
ColdBox has the ability to detect formats via URL extensions or an incoming Accepts
header. If no extension is sent, then ColdBox attempts to determine the format by inspecting the Accepts
header. If we still can't figure out what format to choose, the default of html
is selected for you.
Tip: You can also avoid the extension and pass a URL argument called format
with the correct format type: ?format=json
.
Let's add a new route to our system that is more RESTFul than /contacts/index.json
. You will do so by leveraging the application's router found at config/Router.cfc
. Find the configure()
method and let's add a new route:
The route()
method allows you to register new URL patterns in your application and immediately route them to a target event. You can even give it a human readable name that can be later referenced in the buildLink()
method.
Make sure you add routes above the default ColdBox route. If not, your route will never fire.
We have now created a new URL route called /api/contacts
that if detected will execute the contacts.index
event. Now reinit the application, why, well we changed the application router and we need the changes to take effect.
Tip: Every time you add new routes make sure you reinit the application: http://localhost:{port}/?fwreinit
.
You can now visit the new URL pattern and you have successfully built a RESTFul API for your contacts.
You can find much more about routing in our full docs

Every time the framework renders a view, it will try to leverage the default layout which is located in layouts/Main.cfm
by convention. This is an HTML file that gives format to your output and contains the location of where the view you want should be rendered.
This location is identified by the following code:
The call to the renderView()
method with no arguments tells the framework to render the view that was set using event.setView()
. This is called a rendering region. You can use as many rendering regions within layouts or even within views themselves.
Named Regions: The setView()
method even allows you to name these regions and then render them in any layout or other views using their name.
Let's create a new simple layout with two rendering regions. Open up CommandBox and issue the following commands:
Open the layouts/Funky.cfm
layout and let's modify it a bit by adding the footer view as a rendering region.
Now, let's open the handler we created before called handlers/hello.cfc
and add some code to use our new layout explicitly via adding a layout
argument to our setView()
call.
Go execute the event now: http://localhost:{port}/hello/index
and you will see the view rendered with the words funky layout
and footer view
at the bottom. Eureka, you have now created a layout.
You can also leverage the function event.setLayout( "Funky" )
to change layouts and even concatenate the calls:
event.setView( "hello/index" )
.setLayout( "Funky" );
In order to create a ColdBox application you must adhere to some naming conventions and a pre-set directory structure. This is needed in order for ColdBox to find what it needs and to help you find modules more easily instead of configuring every single area of your application.
ColdBox relies on conventions instead of configurations.
You can also configure many aspects of ColdBox, third-party modules and application settings in our programmtic configuration object: ColdBox.cfc
.
Please note that anytime you make any configuration changes or there are things in memory you wish to clear out, you will be using a URL action that will tell the ColdBox Bootstrapper to reinitialize the application. This special URL variable is called fwreinit
and can be any value or a specific password you setup in the ColdBox configuration directive.
You can also use CommandBox to reinit your application if you are using its embedded server:
The CacheBox structure is based on the CacheBox declaration DSL, and it allows you to customize the caches in your application. Below are the main keys you can fill out, but we recommend you review the CacheBox documentation for further detail.
Info : We would recommend you create a
config/CacheBox.cfc
and put all your caching configuration there instead of in the main ColdBox configuration file. This will give you further portability and decoupling.
An absolute or relative path to the CacheBox configuration CFC or XML file to use instead of declaring the rest of the keys in this structure. So if you do not define a cacheBox structure, the framework will look for the default value: config/CacheBox.cfc
and it will load it if found. If not found, it will use the default CacheBox configuration found in /coldbox/system/web/config/CacheBox.cfc
A structure that enables scope registration of the CacheBox factory in either server, cluster, application or session scope.
The configuration of the default cache which will have an implicit name of default which is a reserved cache name. It also has a default provider of CacheBox which cannot be changed.
A structure where you can create more named caches for usage in your CacheBox factory.
The core conventions delineate the contract between ColdBox and you for file/directory locations and more. Below is a table of the core conventions:
config/Coldbox.cfc - Your application configuration object (optional)
config/Router.cfc - Your application URL Router (optional)
handlers - This holds the app's controllers
layouts - Your HTML layouts
models - This holds your app's CFCs
modules - This holds the CommandBox tracked modules
modules_app - This holds your app's modules
views - Your HTML views will go here

Default Event
main.index
The default event to execute when no event is specified
Default Action

The basic configuration object has 1 method for application configuration called configure()
where you will place all your configuration directives and settings:
Inside of this configuration method you will place several core and third-party configuration structures that can alter your application settings and behavior. Below are the core directives you can define:

Let's complete our saga into MVC by developing the M, which stands for model. This layer is all your business logic, queries, external dependencies, etc. of your application, which represents the problem to solve or the domain to solve.
This layer is controlled by WireBox, the dependency injection framework within ColdBox, which will give you the flexibility of wiring your objects and persisting them for you.
Let's create a simple contact listing, so open up CommandBox and issue the following command:
This will create a models/ContactService.cfc
with a getAll()
method and a companion unit test at tests/specs/unit/ContactServiceTest.cfc
. Let's open the model object:
Notice the singleton
annotation on the component tag. This tells WireBox that this service should be cached for the entire application life-span. If you remove the annotation, then the service will become a transient object, which means that it will be re-created every time it is requested.
Let's mock an array of contacts so we can display them later. We can move this to a SQL call later.
We also have created a project to mock any type of data: MockDataCFC. Just use CommandBox to install it: install mockdatacfc
You can then leverage it to mock your contacts or any simple/complex data requirement.
We have now created our model so let's tell our event handler about it. Let's create a new handler using CommandBox:
This will create the handler/contacts.cfc
handler with an index()
action, the views/contacts/index.cfm
view and the accompanying integration test tests/specs/integration/contactsTest.cfc
.
Let's open the handler and add a new ColdFusion property
that will have a reference to our model object.
Please note that inject
annotation on the property
definition. This tells WireBox what model to inject into the handler's variables
scope.
By convention it looks in the models
folder for the value, which in our case is ContactService
. Now let's call it and place some data in the private request collection prc
so our views can use it.
Now that we have put the array of contacts into the prc
struct as aContacts
, let's display it to the screen using ColdBox's HTML Helper.
The ColdBox HTML Helper is a companion class that exists in all layouts and views that allows you to generate semantic HTML5 without the needed verbosity of nesting, or binding to ORM/Business objects.
Please check out the API Docs to discover the HTML Helper: http://apidocs.ortussolutions.com/coldbox/current/index.html?coldbox/system/modules/HTMLHelper/models/HTMLHelper.html
Open the contacts/index.cfm
and add the following to the view:
Note: If your models are singletons
, they will persist for the life-span of your ColdFusion application. To see code changes for singletons, you have to reinit the framework by using the ?fwreinit={password}
Url action or via CommandBox using coldbox reinit
. Please check out the API Docs to discover CommandBox: [https://apidocs.ortussolutions.com/commandbox/4.5.0/index.html]
That's it! Execute the event: http://localhost:{port}/contacts/index

The ColdBox HMVC Platform is the de-facto enterprise-level HMVC framework for CFML developers. It's professionally backed, highly extensible, and productive. Getting started with ColdBox is quick and painless. The only thing you need to begin is CommandBox, a command line tool for CFML developers.
This is a one-page introductory guide to ColdBox. If you are new to MVC or ColdBox, you can also leverage our 60 minute quick start guide as well.
ColdBox has the following supported IDE Tools:
You can read through our one-page CommandBox Getting Started Guide. Or simply grab the CommandBox executable from the download page and double click it to run.

You should now be seeing a prompt that looks like this:
Now we're cooking with gas! Let's create a new ColdBox application. CommandBox comes with built-in commands for scaffolding out new sites as well as installing ColdBox and other libraries. We'll start by changing into an empty directory were we want our new app to live. If necessary, you can create a new folder.
Now let's ask CommandBox to create a new ColdBox app for us.
Tip: You can find many scaffolding templates for ColdBox in our Github organization: github.com/coldbox-templates
You can also issue a coldbox create app help
command and get help for the creation command.
This command will place several new folders and files in your working directory. Let's run the ls
command to view them.
Here's a rundown of the important bits.
coldbox - This is the ColdBox framework managed by CommandBox
config/Coldbox.cfc - Your application configuration object
config/Router.cfc - Your application URL Router
handlers - Your controller layer, which in ColdBox they are called event handlers
layouts - Your HTML layouts
models - This holds your model CFCs
modules - This holds the CommandBox tracked modules
modules_app - This holds your app's modules
views - Your HTML views will go here
Now that our shiny new MVC app is ready to go, let's fire it up using the embedded server built into CommandBox. You don't need any other software installed on your PC for this to work. CommandBox has it all!
In a few seconds, a browser window will appear with your running application. This is a full server with access to the web administrator where you can add data sources, mappings, or adjust the server settings. Notice the handy icon added to your system tray as well. The --rewritesEnable
flag will turn on some basic URL rewriting so we have nice, pretty URLs.
Tip: If you are creating an app to run on any other server than the commandbox server, you will need to manually set up URL rewriting. More info here: /the-basics/routing/requirements
ColdBox uses easy conventions to define the controllers and views in your app. Let's open up our main app controller in your default editor to have a looksie.
At the top, you'll see a function named "index". This represents the default action that runs for this controller, which in ColdBox land they are referred to as event handlers.
Now let's take a look in the main/index
view. It's located int he views
folder.
This line of code near the top of the view is what outputs the prc.welcomeMessage
variable we set in the controller.
Try changing the value being set in the handler and refresh your browser to see the change.
Let's define a new event handler now. Your controllers act as event handlers to respond to requests, REST API, or remote proxies.
Pull up CommandBox again and run this command.
That's it! You don't need to add any special configuration to declare your handler. Now we have a new handler called helloWorld
with actions index
, add
, edit
, and list
. The command also created a test case for our handler as well as stubbed-out views for each of the actions.
Now, let's re-initialize the framework to pick up our new handler by typing ?fwreinit=1
at the end of the URL.
Let's hit this new controller we created with a URL like so. Your port number will probably be different.
127.0.0.1:43272/helloWorld
Normally the URL would have index.cfm
before the /helloWorld
bit, but our --rewritesEnable
flag when we started the server makes this nicer URL possible.
ColdBox's MVC is simple, but it's true power comes from the wide selection of modules you can install into your app to get additional functionality. You can checkout the full list of modules available on the Forgebox directory: www.forgebox.io.
Here's some useful examples:
BCrypt -- Industry-standard password hashing
cbdebugger -- For debugging Coldbox apps
cbjavaloader - For interacting with Java classes and libraries
cbMarkdown - For writing in markdown
cbMessagebox -- Display nice error/success messages
cborm -- Awesome ORM Services
cb18n -- For multilingual sites
cbt - ColdBox templating language
cbValidation - Back-end validation framework
qb - Fluent query builder and schema builder
route-visualizer - For visualizing your application routes
Install cbmessagebox
from the CommandBox prompt like this:
We can see the full list of packages by using the list
command.
Right now we can see that our app depends on coldbox
and cbmessagebox
to run. We'll use our new cbmessagebox
module in a few minutes. But first, we'll create a simple Model CFC to round out our MVC
app.
Models encapsulate the business logic your application. They can be services, beans, or DAOs. We'll use CommandBox to create a GreeterService
in our new app with a sayHello
method.
Tip: The --open
is a nice shortcut that opens our new model in our default editor after creating it.
Let's finish implementing the sayHello()
method by adding this return statement and save the file.
We can also add the word singleton
to the component declaration. This will tell WireBox to only create one instance of our service.
What is WireBox?
WireBox is a dependency injection framework that is included with ColdBox. It will manage all object creations, persistence and assembling. You don't have to worry about using new
or createobject()
for CFCs anymore.
Ok, let's open up that helloWorld
handler we created a while back. Remember, you can hit tab while typing to auto-complete your file names.
We'll inject our greeterService
and the cbmessagebox
service into the handler by adding these properties to the top of /handlers/helloWorld.cfc
.
What is this magical injection? Injection is a way to get references of other objects placed in the variables
scope of other objects. This makes your life easier as you don't have to be creating objects manually or even knowing where they exist.
This will put the instance of our services in the variables
scope where we can access it in our action methods.
And now in our index
method, we'll set the output of our service into an info
message.
One final piece. Open up the default layout located in layouts/Main.cfm
and find the #renderView()#
. Add this line right before it to render out the message box that we set in our handler.
Now hit your helloWorld
handler one final time with ?fwreinit=1
in the URL to see it all in action! (Again, your port number will most likely be different.
127.0.0.1:43272/helloWorld?fwreinit=1
Congratulations! In a matter of minutes, you have created a full MVC application. You installed a community module from ForgeBox, created a new handler/view and tied in business logic from a service model.
As easy as that was, you're just scratching the surface of what ColdBox can do for you. Continue reading this book to learn more about:
Environment-specific configuration
Easy SES URL routing
Tons of 3rd party modules
Drop-in security system
Sweet REST web service support

Event handlers are the controller layer in ColdBox and is what you will be executing via the URL
or a FORM
post. All event handlers are singletons, which means they are cached for the duration of the application, so always remember to var scope your variables in your functions.
Tip: For development we highly encourage you to turn handler caching off or you will have to reinit the application in every request, which is annoying. Open the config/ColdBox.cfc
and look for the coldbox.handlerCaching
setting.
Once you started the server in the previous section and opened the browser, the default event got executed which maps to an event handler CFC (controller) handlers/main.cfc
and the method/action in that CFC called index()
. Go open the handlers/main.cfc
and let's explore the code.
Every action in ColdBox receives three arguments:
event
- An object that models and is used to work with the current request
rc
- A struct that contains both URL/FORM variables (unsafe data)
prc
- A secondary struct that is private only settable from within your application (safe data)
This line event.setView( "main/index" )
told ColdBox to render a view back to the user found in views/main/index.cfm
using a default layout, which by convention is called Main.cfm
which can be found in the layouts
folder.
We have now seen how to add handlers via CommandBox using the coldbox create handler
command and also execute them by convention by leveraging the following URL pattern:
Also remember, that if no action
is defined in the incoming URL then the default action of index
will be used.
Remember that the URL mappings support in ColdBox is what allows you to execute events in such a way from the URL. These are controlled by your application router: config/Router.cfc
Now, let's open the handler we created before called handlers/hello.cfc
and add some public and private variables to it so our views can render the variables.
Let's open the view now: views/hello/index.cfm
and change it to this:
Please note that we used the ColdFusion function encodeForHTML()
(https://www.cfdocs.org/encodeforhtml) on the public variable. Why? Because you can never trust the client and what they send, make sure you use the built-in ColdFusion encoding functions in order to avoid XSS hacks or worse on incoming public (rc
) variables.
If you execute the event now: http://localhost:{port}/hello/index
you will see a message of Hello nobody
.
Now change the incoming URL to this: http://localhost:{port}/hello/index?name=ColdBox
and you will see a message of Hello ColdBox
.
Tip: Please see the layouts and views section for in-depth information about them.
The ColdBox configuration CFC is the heart of your ColdBox application. It contains the initialization variables for your application and extra information used by third-party modules and ultimately how your application boots up. In itself, it is also an event listener or ColdBox Interceptor, so it can listen to life-cycle events of your application.
This CFC is instantiated by ColdBox and decorated at runtime so you can take advantage of some dependencies.
Controller : Reference to the main ColdBox Controller object (coldbox.system.web.Controller
)
AppMapping : The location of the application on the web server
LogBoxConfig : A reference to a LogBox configuration object
Once the application starts up, a reference to the instantiated configuration CFC will be stored in the configuration settings with the key coldboxConfig
. You can then retrieve it later in your handlers, interceptors, modules, etc.
Another cool concept for the Configuration CFC is that it is also registered as a ColdBox Interceptor once the application starts up automatically for you. Create functions that will listen to application events:
Note that the config CFC does not have the same variables mixed into it that a "normal" interceptor has. You can still access everything you need, but will need to get it from the controller
in the variables scope.
Welcome to the world of ColdBox!
We are excited you are taking this development journey with us. Before we get started with ColdBox let's install CommandBox CLI, which will allow you to install/uninstall dependencies, start servers, have a REPL tool and much more.
ColdBox has the following supported IDE Tools:
The first step in our journey is to install CommandBox. CommandBox is a ColdFusion (CFML) Command Line Interface (CLI), REPL, Package Manager and Embedded Server. We will be using CommandBox for almost every excercise in this book and it will also allow you to get up and running with ColdFusion and ColdBox in a much speedier manner.
Note : However, you can use your own ColdFusion server setup as you see fit. We use CommandBox as everything is scriptable and fast!
You can download CommandBox from the official site: https://www.ortussolutions.com/products/commandbox#download and install in your preferred Operating System (Windows, Mac, *unix). CommandBox comes in two flavors:
No Java Runtime (30mb)
Embedded Runtime (80mb)
So make sure you choose your desired installation path and follow the instructions here: https://commandbox.ortusbooks.com/content/setup/installation.html
Once you download and expand CommandBox you will have the box.exe
or box
binary, which you can place in your Windows Path or *Unix /usr/bin
folder to have it available system wide. Then just open the binary and CommandBox will unpack itself your user's directory: {User}/.CommandBox
. This happens only once and the next thing you know, you are in the CommandBox interactive shell!
We will be able to execute a-la-carte commands from our command line or go into the interactive shell for multiple commands. We recommend the interactive shell as it is faster and can remain open in your project root.
All examples in this book are based on the fact of having an interactive shell open.
To get started open the CommandBox binary or enter the shell by typing box
in your terminal or console. Then let's create a new folder and install ColdBox into a directory.
CommandBox will resolve coldbox
from ForgeBox (www.forgebox.io), use the latest version available, download and install it in this folder alongside a box.json
file which represents your application package.
You can also install the latest bleeding edge version by using the coldbox@be
slug instead, or any previous version.
That's it! CommandBox can now track this version of ColdBox for you in this directory.
CommandBox comes with a coldbox create app
command that can enable you to create application skeletons using one of our official skeletons or by creating your own application template:
Advanced : A tag based advanced template
AdvancedScript (default
): A script based advanced template
elixir : A ColdBox Elixir based template
ElixirBower : A ColdBox Elixir + Bower based template
ElixirVueJS : A ColdBox Elixir + Vue.js based template
rest: A RESTFul services template
rest-hmvc: A RESTFul service built with modules
Simple : A traditional simple template
SuperSimple : The bare-bones template
You can find many scaffolding templates for ColdBox in our Github organization: github.com/coldbox-templates
Type coldbox create app
help in CommandBox to get tons of help for scaffolding apps.
To uninstall ColdBox from this application folder just type uninstall coldbox
.
To update ColdBox from a previous version, just type update coldbox
.
The configuration CFC has embedded environment control and detection built-in. Environments kan be detected by:
regex matching against cgi.http_host
detection of an environmental variable called ENVIRONMENT ( Coldbox 5.2 and higher )
usage of a detectEnvironment()
function
The first option (regex matching) is the easiest to use, but not very reliable if you are using multiple hostnames or commandbox for re-initialization.
If you are using commandbox
please read ALL options below
To detect your environments you will setup a structure called environments
in your coldbox configuration with the named environments and their associated regular expressions for its cgi
host names to match for you automatically. If the framework matches the regex with the associated cgi.http_host
, it will set a setting called Environment
in your configuration settings and look for that environment setting name in your CFC as a method by convention. That's right, it will check if your CFC has a method with the same name as the environment and if it exists, it will call it for you. Here is where you basically override, remove, or add any settings according to your environment.
Warning : The environment detection occurs AFTER the
configure()
method is called. Therefore, whatever settings or configurations you have on theconfigure()
method will be stored first, treat those as Production settings.
The regex match will also create a global setting called "environment" which you can access and use like this:
In the above example, I declare a development key with a value list of regular expressions. If I am in a host that starts with cf2016, this will match and set the environment setting equal to development. It will then look for a development method in this CFC and execute it.
If you are using environmental variables for your different environments, you can specify an environmental variable called ENVIRONMENT and name it staging
, development
, testing
etcetera, depending on the required environment. As in the regex example, a function named after your environment (e.g. staging()
or development()
) will be called after your configure
method.
This method is more reliable than relying on cgi.http_host, since it will never change once configured correctly.
If you are NOT using environmental variables you can use your own detection algorithm instead of looking at the cgi.http_host
variable. You will NOT fill out an environments structure but actually create a method with the following signature:
This method will be executed for you at startup and it must return the name of the environment the application is on. You can check for any condition which distinguishes your environment from your other environments. Als long as you return a environment name based on your own logic it will then store it and execute the method if it exists.
The layouts array element is used to define implicit associations between layouts and views/folders, this does not mean that you need to register ALL your layouts. This is a convenience for pairing them, we are in a conventions framework remember.
Before any renderings occur or lookups, the framework will check this array of associations to try and match in what layout a view should be rendered in. It is also used to create aliases for layouts so you can use aliases in your code instead of the real file name and locations.
This directive is how you will configure the for operation. Below are the configuration keys and their defaults:
This element defines custom conventions for your application. By default, the framework has a default set of conventions that you need to adhere too. However, if you would like to implement your own conventions for a specific application, you can use this setting, otherwise do not declare it:
This structure configures the interceptor service in your application.
throwOnInvalidStates
This tells the interceptor service to throw an exception if the state announced for interception is not valid or does not exist. Defaults to false.
customInterceptionPoints
This key is a comma delimited list or an array of custom interception points you will be registering for custom announcements in your application. This is the way to provide an observer-observable pattern to your applications.
Info Please see the section for more information.
This is an array of interceptor definitions that you will use to register in your application. The key about this array is that ORDER matters. The interceptors will fire in the order that you register them whenever their interception points are announced, so please watch out for this caveat. Each array element is a structure that describes what interceptor to register.
Warning : Important: Order of declaration matters! Also, when declaring multiple instances of the same CFC (interceptor), make sure you use the name attribute in order to distinguish them. If not, only one will be registered (the last one declared).
The ColdBox directive is where you configure the framework for operation.
Info : Please note that there are no mandatory settings as of ColdBox 4.2.0. If fact, you can remove the config file completely and your app will run. It will be impossible to reinit the app however without a reinit password set.
Protect the reinitialization of the framework URL actions. For security, if this setting is omitted, we will create a random password. Setting it to an empty string will allow you to reinitialize without a password. Always have a password set for public-facing sites.
Will scan the conventions directory for new handler CFCs on each request if activated. Use false for production, this is only a development true setting.
These settings map 1-1 from ColdBox events to the Application.cfc
life-cycle methods. The only one that is not is the defaultEvent
, which selects what event the framework will execute when no incoming event is detected via URL/FORM or REMOTE executions.
The ColdBox extension points are a great way to create federated applications that can reuse a centralized core instead of the local conventions. It is also a great way to extend some core classes with your own.
A list or array of absolute or relative paths to a UDF helper file. The framework will load all the methods found in this helper file globally. Meaning it will be injected in ALL handlers, layouts and views.
A list or array of absolute or relative paths to a UDF helper file. The framework will load all the methods found in this helper in layouts and views only.
A list or array of locations of where ColdBox should look for modules to load into your application. The path can be a cf mapping or cfinclude
compatible location. Modules are searched and loaded in the order of the declared locations. The first location ColdBox will search for modules is the conventions folder modules
The CF include path of where to look for secondary views for your application. Secondary views look just like normal views except the framework looks in the conventions folder first and if not found then searches this location.
The CF include path of where to look for secondary layouts for your application. Secondary layouts look just like normal layouts except the framework looks in the conventions folder first and if not found then searches this location.
The CF dot notation path of where to look for secondary events for your application. Secondary events look just like normal events except the framework looks in the conventions folder first and if not found then searches this location.
The CF dot notation path of the CFC that will decorate the system Request Context object.
The CF dot notation path of the CFC that will decorate the system Controller
The event handler to call whenever ANY non-catched exception occurs anywhere in the request lifecycle execution. Before this event is fired, the framework will log the error and place the exception in the prc as prc.exception
.
The event handler to call whenever a route or event is accessed with an invalid HTTP method.
This is the event handler that will fire masking a non-existent event that gets requested. This is a great place to place 302 or 404 redirects whenever non-existent events are being requested.
The relative path from the application's root level of where the custom error template exists. This template receives a key in the private request collection called exception
that contains the exception. By default ColdBox does not show robust exceptions, you can turn on robust exceptions by choosing the following template:
This is useful to be set to false in development and true in production. This tells the framework to cache your event handler objects as singletons.
This directive tells ColdBox that when events are executed they will be inspected for caching metadata. This does not mean that ALL events WILL be cached if this setting is turned on. It just activates the inspection mechanisms for whenever you annotate events for caching or using the runEvent()
caching methods.
This directive tells ColdBox that when views are rendered, the cache=true
parameter will be obeyed. Turning on this setting will not cause any views to be cached unless you are also passing in the caching parameters to your renderView()
or event.setView()
calls.
This is a boolean setting used when calling the ColdBox proxy's process()
method from a Flex or SOAP/REST call. If this setting is set to true, the proxy will return back to the remote call the entire request collection structure ALWAYS! If set to false, it will return, whatever the event handler returned back. Our best practice is to always have this false and return appropriate data back.
Allows you to use implicit views in your application and view dispatching. You can get a performance boost if you disable this setting.
By default implicit views are case sensitive since ColdBox version 5.2.0, before this version the default was false.
ColdBox by convention can talk to, use and inject models from the models
folder by just using their name. However, once you built complex hierarchies you would have to specify the specific hierarchy or folder structure for the model; This is a limitation of conventions. Your choices before v5.2.0 was to map the objects yourself in the WireBox binder. Now, if you turn this setting to true, we will issue a mapDirectory()
on the models
directory for you.
A structure where you will configure the
This structure allows you to define a system-wide default layout and view.
Hint Please remember that the default layout is
Main.cfm
This structure is used to house module configurations. Please refer to each module's documentation on how to create the configuration structures. Usually the keys will match the name of the module to be configured.
These are custom application settings that you can leverage in your application.
You can read our Using Settings section to discover how to use all the settings in your application.
This configuration structure is used to configure the WireBox dependency injection framework embedded in ColdBox.
binder
The location of the WireBox configuration binder to use for the application. If empty, we will use the binder in the config
folder called by conventions: WireBox.cfc
singletonReload
A great flag for development. If enabled, WireBox will flush its singleton objects on every request so you can develop without any headaches of reloading.
Warning : This operation can cause some thread issues and it is only meant for development. Use at your own risk.
The logBox structure is based on the LogBox declaration DSL, see the LogBox Documentation for much more information.
Info : If you do not define a logBox DSL structure, the framework will look for the default configuration file
config/LogBox.cfc
. If it does not find it, then it will use the framework's default logging settings.
ConfigFile
You can use a configuration CFC instead of inline configuration by using this setting. The default value is config/LogBox.cfc
, so by convention you can just use that location. If no values are defined or no config file exists, the default configuration file is coldbox/system/web/config/LogBox.cfc
.
The modules structure is used to configure the behavior of the ColdBox Modules.
Danger Please be very careful when using the
autoReload
flag as module routing can be impaired and thread consistency will also suffer. This is PURELY a development flag that you can use at your own risk.
Routing is enabled by default in the ColdBox application templates in order to work with URL's like this:
http://localhost/index.cfm/home/about
As you can see they still contain the index.cfm
in the URL. In order to enable full URL rewrites that eliminates that index.cfm
you must have a rewrite enabled webserver like Apache, nginx or IIS or a Java rewrite filter which ships with CommandBox by default.
http://localhost/home/about
CommandBox has built in rewrites powered by Tuckey and you can enable a server with rewrites by running:
Caution Some J2EE servlet containers do not support the forwarding of SES parameters via the routing template (index.cfm
) out of the box. You might need to enable full URL rewriting either through a web server or a J2EE filter.
Apache mod_rewrite via .htaccess or configuration files (Free)
Helicon Tech ISAPI rewrite filter for IIS (Paid)
IIS 7 native rewrite filter (Free)
nginx native web server (free)
Tuckey J2EE rewrite filter (free)
ColdBox supports a Routing Service that will provide you with robust URL mappings for building expressive applications and RESTFul services. By convention URL routing will allow you to create URL's without using verbose parameter delimiters like ?event=this.that&m1=val
and execute ColdBox events.
If you are leveraging CommandBox as your server, then full URL rewrites are enabled by default. This means you do not need a web server to remove the index.cfm
from the URL.
A route is a declared URL pattern that if matched it will translate the URL into one of the following:
A ColdBox event to execute
A View/Layout to render
A Reponse function to execute
A Redirection to occur
It will also inspect the URL for placeholders and translate them into the incoming Request Collection variables (RC
).
Examples
There are several benefits that you will get by using our routing system:
Complete control of how URL's are built and managed
Ability to create or build URLs' dynamically
Technology hiding
Greater application portability
URL's are more descriptive and easier to remember
As you create route-heavy applications visualizing the routes will be challenging especially for HMVC apps with lots of modules. Just install our ColdBox Route Visualizer and you will be able to visually see, test and debug all your routing needs.
In your URL pattern you can also use the :
syntax to denote a variable placeholder. These position holders are alphanumeric by default:
Once a URL is matched to the route above, the placeholders (:year/:month?/:day?
) will become request collection (RC
) variables:
Sometimes we will want to declare routes that are very similar in nature and since order matters, they need to be delcared in the right order. Like this one:
However, we just wrote 4 routes for this approach when we can just use optional variables by using the ?
symbol at the end of the placeholder. This tells the processor to create the routes for you in the most detailed manner first instead of you doing it manually.
Caution Just remember that an optional placeholder cannot be followed by a non-optional one. It doesn't make sense.
ColdBox gives you also the ability to declare numerical only routes by appending -numeric
to the variable placeholder so the route will only match if the placeholder is numeric. Let's modify the route from above.
This route will only accept years, months and days as numbers.
ColdBox gives you also the ability to declare alpha only routes by appending -alpha
to the variable placeholder so the route will only match if the placeholder is alpha
only.
This route will only accept page names that are alpha only.
There are two ways to place a regex constraint on a placeholder, using the -regex:
placeholder or adding a constraints
structure to the route declaration.
You can also have the ability to declare a placeholder that must match a regular expression by using the -regex( {regex_here} )
placeholder.
The rc
variable format
must match the regex supplied: (xml|json)
You can also apply a structure of regular expressions to a route instead of inlining the regular expressions in the placeholder location. You will do this using the constraints()
method of the router.
The key in the structure must match the name of the placeholder and the value is a regex expression that must be enclosed by parenthesis ()
.
The Application.cfc
is one of the most important files in your application as it is where you define all the implicit ColdFusion engine events, session, client scopes, ORM, etc. It is also how you tell ColdFusion to bootstrap the ColdBox Platform for your application. There are two ways to bootstrap your application:
Leverage composition and bootstrap ColdBox (Default)
Leverage inheritance and bootstrap ColdBox
The composition approach allows you to have a more flexible configuration as it will allow you to use per-application mappings for the location of the ColdBox Platform.
Tip: To see the difference, just open the appropriate Application.cfc
in the application templates.
You can set some variables in the Application.cfc
that can alter Bootstrapping conditions:
Variable
Default
Description
COLDBOX_APP_ROOT_PATH
App Directory
Automatically set for you. This path tells the framework what is the base root location of your application and where it should start looking for all the agreed upon conventions. You usualy will never change this, but you can.
COLDBOX_APP_MAPPING
/
The application mapping is ESSENTIAL when dealing with Flex or Remote (SOAP) applications. This is the location of the application from the root of the web root. So if your app is at the root, leave this setting blank. If your application is embedded in a sub-folder like MyApp, then this setting will be auto-calculated to /MyApp
.
COLDBOX_CONFIG_FILE
config/ColdBox.cfc
The absolute or relative path to the configuration CFC file to load. This bypasses the conventions and uses the configuration file of your choice.
COLDBOX_APP_KEY
cbController
The name of the key the framework will store the application controller under in the application scope.
The Boostrapper also leverages a default locking timeout of 30 seconds when doing loading operations. You can modify this timeout by calling the setLockTimeout()
method on the Bootsrapper object.
The ColdBox Controller (stored in ColdFusion application
scope) stores all your application settings and also your system settings:
ColdboxSettings : Framework specific system settings
ConfigSettings : Your application settings
You can use the following methods to retrieve/set/validate settings in your handlers/layouts/views and interceptors:
You can also get access to these methods via the ColdBox Controller component:
You can use the WireBox injection DSL to inject settings in your models or non-coldbox objects. Below are the available DSL notations:
coldbox:setting:{key}
: Inject a specified config setting key
coldbox:fwsetting:{key}
: Inject a specified system setting key
coldbox:configSettings
: Inject a reference to the application settings structure
coldbox:fwSettings
: Inject a reference to the ColdBox System settings structure
On every request to a ColdBox event, the framework creates an object that models the incoming request. This object is called the Request Context Object(coldbox.system.web.context.RequestContext
), it contains the incoming FORM/REMOTE/URL variables the client sent in and the object lives in the ColdFusion request
scope.
Please visit the latest API Docs for further information about the request context.
This object contains two structures internally:
RC
- The Request Collection which contains the FORM/REMOTE/URL data merged into a single structure. This is considered to be unsafe data as it comes from any request.
PRC
- The Private Request Collection which is a structure that can be used to safely store sensitive data. This structure cannot be modified from the outside world.
The order of preference of variables when merged is FORM first then REMOTE then URL.
REMOTE variables are from leveraging the ColdBox Proxy.
You will use these objects in the controller and view layer of your application to get/set values, get metadata about the request, generate URLs, transform data for RESTful requests, and so much more. It is the glue that binds the controller and view layer together. As we progress in the guides, you will progress in mastering the request context.
Note that there is no model layer in the diagram. This is by design; the model will receive data from the handlers/interceptors directly.
Below you can see a listing of the most commonly used methods in the request context object. Please note that when interacting with a collection you usually have an equal private collection method.
buildLink() : Build a link in SES or non SES mode for you with tons of nice abstractions.
clearCollection() : Clears the entire collection
collectionAppend() : Append a collection overwriting or not
getCollection() : Get a reference to the collection
getEventName() : The event name in use in the application (e.g. do, event, fa)
getSelf() : Returns index.cfm?event=
getValue() : get a value
getTrimValue() : get a value trimmed
isProxyRequest() : flag if the request is an incoming proxy request
isSES() : flag if ses is turned on
isAjax() : Is this request ajax based or not
noRender(boolean) : flag that tells the framework to not render any html, just process and silently stop.
overrideEvent() : Override the event in the collection
paramValue(): param a value in the collection
removeValue() : remove a value
setValue() : set a value
setLayout() : Set the layout to use for this request
setView() : Used to set a view to render
valueExists() : Checks if a value exists in the collection.
renderData() : Marshall data to JSON, JSONP, XML, WDDX, PDF, HTML, etc.

Every router has a default route already defined for you in the application templates, which we refer to as routing by convention:
The URL pattern in the default route includes two special position placeholders, meaning that the handler and the action will come from the URL. Also note that the :action
has a question mark (?
), which makes the placeholder optional, meaning it can exist or not from the incoming URL.
:handler
- The handler to execute (It can include a Package and/or Module reference)
:action
- The action to relocate to (See the ?
, this means that the action is optional)
Behind the scenes the router creates two routes due to the optional placeholder in the following order:
route( "/:handler/:action" )
route( "/:handler)
Tip The :handler
parameter allows you to nest module names and handler names. Ex: /module/handler/action
If no action is passed the default action is index
This route can handle pretty much all your needs by convention:
Any extra name-value pairs in the remaining URL of a discovered URL pattern will be translated to variables in the request collection (rc
) for you automagically.
Tip: You can turn this feature off by using the valuePairTranslator( false )
modifier in the routing DSL on a route by route basis
route( "/pattern" ).to( "users.show" ).valuePairTranslator( false );
The ColdBox Routing DSL will be used to register routes for your application, which exists in your application or module router object. Routing takes place using several methods inside the router, which are divided into the following 3 categories:
Initiators - Starts a URL pattern registration, but does not fully register the route until a terminator is called (target).
Modifiers - Modifies the pattern with extra metdata to listen to from the incoming request.
Terminators - Finalizes the registration process usually by telling the router what happens when the route pattern is detected. This is refered to as the target.
Please note that order of declaration of the routes is imperative. Order matters.
Please remember to check out the latest for the latest methods and argument signatures.
The following methods are used to initiate a route registration process.
Please note that a route will not register unless a terminator is called or the inline target terminator is passed.
route( pattern, [target], [name] )
- Register a new route with optional target terminators and a name
get( pattern, [target], [name] )
- Register a new route with optional target terminators, a name and a GET http verb restriction
post( pattern, [target], [name] )
- Register a new route with optional target terminators, a name and a POST http verb restriction
put( pattern, [target], [name] )
- Register a new route with optional target terminators, a name and a PUT http verb restriction
patch( pattern, [target], [name] )
- Register a new route with optional target terminators, a name and a PATCH http verb restriction
options( pattern, [target], [name] )
- Register a new route with optional target terminators, a name and a OPTIONS http verb restriction
group( struct options, body )
- Group routes together with options that will be applied to all routes declared in the body
closure/lambda.
Modifiers will tell the routing service about certain restrictions, conditions or locations for the routing process. It will not register the route just yet.
header( name, value, overwrite=true )
- attach a response header if the route matches
headers( map, overwrite=true )
- attach multiple response headers if the route matches
as( name )
- Register the route as a named route
rc( name, value, overwrite=true )
- Add an RC
value if the route matched
rcAppend map, overwrite=true )
- Add multiple values to the RC
collection if the route matched
prc( name, value, overwrite=true )
- Add an PRC
value if the route matched
prcAppend map, overwrite=true )
- Add multiple values to the PRC
collection if the route matched
withHandler( handler )
- Map the route to execute a handler
withAction( action )
- Map the route to execute a single action or a struct that represents verbs and actions
withModule( module )
- Map the route to a module
withNamespace( namespace )
- Map the route to a namespace
withSSL()
- Force SSL
withCondition( condition )
- Apply a runtime closure/lambda enclosure

toAction( action )
- Send the route to a specific action or RESTFul action struct
toView( view, layout, noLayout=false, viewModule, layoutModule )
- Send the route to a view/layout
toRedirect( target, statusCode=301 )

to( event )
- Execute the event if the route matches
toHandler( handler )
- Execute the handler if the route matches
toResponse( body, statusCode=200, statusText="ok" )
- Inline response action
toModuleRouting( module )
- Send to the module router for evaluation
toNamespaceRouting( namespace )
- Send to the namespace router for evaluation
Every ColdBox application has a URL router and can be located by convention at config/Router.cfc
. This is called the application router and it is based on the router core class: coldbox.system.web.routing.Router
. Here is where you will configure router settings and define routes using our routing DSL.
Please see the latest for investigating all the methods and properties of the Router.
Tip: Unlike previous versions of ColdBox, the new routing services in ColdBox 5 are automatically configured to detect the base URLs and support multi-domain hosting. There is no more need to tell the Router about your base URL.
Router.cfc
The application router is a simple CFC that virtually inherits from the core ColdBox Router class and is configured via the configure()
method. It will be decorated with all the capabilities to work with any request much like any event handler or interceptor. In this router you will be doing 1 of 2 things:
Configuring the Router
Adding Routes via the Routing DSL
The router and indeed all module routers are also registered as full fledged ColdBox interceptors. So they can listen to any event within your application.
Once the routing service loads your Router it will create two application settings for you:
SESBaseURL
: The multi-domain URL base URL of your application: http://localhost
HTMLBaseURL
: The same path as SESBaseURL
but without any index.cfm
in it (Just in case you are using index.cfm
rewrite). This is a setting used most likely by the HTML <base>
tag.
You can use the following methods to fine tune the configuration and operation of the routing services:
The next sections will discus how to register routes for your application.
Please note that URL rewriting is handled by an optional module in IIS. More info here:
Method
Description
setEnabled( boolean )
Enable/Disable routing, enabled by default
setFullRewrites( boolean )
If true, then no index.cfm
will be used in the URLs. If false, then /index.cfm/ will be added to all generated URLs. Default is false.
setUniqueURLS( boolean )
Enables SES only URL's with permanent redirects for non-ses urls. Default is true. If true and a URL is detected with ? or & then the application will do a 301 Permanent Redirect and try to translate the URL to a valid SES URL.
setBaseURL( string )
The base URL to use for URL writing and relocations. This is automatically detected by ColdBox 5 e.g. http://www.coldbox.org/, http://mysite.com/index.cfm''
setLooseMatching( boolean )
By default URL pattern matching starts at the beginning of the URL, however, you can choose loose matching so it searches anywhere in the URL. Default is false.
setExtensionDetection( boolean )
By default ColdBox detects URL extensions like json, xml, html, pdf
which can allow you to build awesome RESTful web services. Default is true.
setValidExtensions( list )
Tell the interceptor what valid extensions your application can listen to. By default it listens to: json, jsont, xml, cfm, cfml, html, htm, rss, pdf
setThrowOnInvalidExtensions( boolean )
By default ColdBox does not throw an exception when an invalid extension is detected. If true, then the interceptor will throw a 406 Invalid Requested Format Extension: {extension} exception. Default is false.
You can create a-la-carte namespaces for URL routes. Namespaces are cool groupings of routes according to a specific URL entry point. So you can say that all URLs that start with /testing
will be found in the testing namespace and it will iterate through the namespace routes until it matches one of them.
Much how modules work, where you have a module entry point, you can create virtual entry point to ANY route by namespacing it. This route can be a module a non-module, package, or whatever you like. You start off by registering the namespace using the addNamespace( pattern, namespace )
method or the fluent route().toNamespaceRouting()
method.
Once you declare the namespace you can use the grouping functionality to declare all the namespace routes or you can use a route().withNamespace()
combination.
Hint You can also register multiple URL patterns that point to the same namespace
The base
tag in HTML allows you to tell the browser what is the base URL for assets in your application. This is something that is always missed when using frameworks that enable routing.
base
tag defines the base location for links on a page. Relative links within a document (such as <a href="someplace.html"... or <img src="someimage.jpg"... ) will become relative to the URI specified in the base tag. The base tag must go inside the head element.
We definitely recommend using this HTML tag reference as it will simplify your asset retrievals.
Caution If you do not use this tag, then every asset reference must be an absolute URL reference.
By default, the URL mapping processor will detect routes by looking at the CGI.PATH_INFO
variable, but you can override this and provide your own function. This feature can be useful to set flags for each request based on a URL and then clean or parse the URL to a more generic form to allow for simple route declarations. Uses may include internationalization (i18n) and supporting multiple experiences based on devices such as Desktop, Tablet, Mobile and TV.
To modify the URI used by the Routing Services before route detection occurs simply follow the convention of adding a function called pathInfoProvider()
to your application Router (config/Router.cfc
).
The pathInfoProvider()
function is responsible for returning the string used to match a route.
In your views, layouts and handlers you can use the buildLink
method provided by the request context object (event) to build routable links in your application.
Just pass in the routed URL or event and it will create the appropriate routed URL for you:
The request context object (event) also has some handy methods to tell you the name or even the current route that was selected for execution:
getCurrentRouteName()
- Gives you the name of the current route, if any
getCurrentRoute()
- Gives you the currently executed route
getCurrentRoutedURL()
- Gives you the complete routed URL pattern that matched the route
getCurrentRoutedNamespace()
- Gives you the current routed namespace, if any
There will be a time where your routes will become very verbose and you would like to group them into logical declarations. These groupings can also help you prefixes repetitive patterns in many routes with a single declarative construct. These needs are met with the group()
method in the router.
The best way to see how it works is by example:
As you can see from the routes above, we have lots of repetitive code that we can clean out. So let's look at the same routes but using some nice grouping action.
The options struct can contain any values that you can use within the closure. Grouping can also be very nice when creating namespaces, which is our next section.
Event handlers are ColdBox's version of controllers in the MVC design pattern. So every time you hear "event handler", you are talking about a controller that can listen to external events or internal events in ColdBox. Event handlers are responsible for controlling your application flow, calling business logic, preparing a display to a user and much more.
Tip: You can create packages or sub-folders inside of the handlers directory. This is encouraged on large applications so you can organize or package handlers logically to facilitate better maintenance and URL experience.
If an external event handler has the same name as an internal conventions event, the internal conventions event will take precedence.
By default, ColdBox will only scan for event handlers on startup. For development we highly encourage you leverage the following configuration directives:
They are composed of functions which are called actions that will always have the following signature:
Each action receives three arguments:
event
- An object that models and is used to work with the current request
rc
- A struct that contains both URL/FORM
variables (unsafe data)
prc
- A secondary struct that is private. This structure is only accessible from within your application (safe data)
An action will usually do one of the following:
Set a view/layout to render
Return HTML
Return Complex Data which is converted to JSON by default
Relocate to another event/URL Route
The default action for all event handlers is called index()
. This means that when you execute an event, you can omit the index if you so desire.
So what about private
functions? Private functions are not executable from the outside world, but can be executed internally via a function available to all handlers called runEvent()
, which we will explore later.
It is important to note that there is a pre-defined object model behind every event handler controller that will enable you to do your work more efficiently. The following are the automatically generated properties every event handler makes available in their variables
scope:)
controller : A reference to the Application Controller (coldbox.system.web.Controller
)
flash: A flash memory object (coldbox.system.web.flash.AbstractFlashScope
)
$super: A reference to the virtual super class if using non-inheritance approach.
We all need values in our applications. That is why we interact with the in order to place data from our model layer into it so our views can display it, or to retrieve data from a user's request. You will either interact with the event object to get/set values or put/read values directly via the received rc
and prc
references.
We would recommend you use the private request collection (prc
) for setting manual data and using the standard request collection (rc
) for reading the user's unsafe request variables. This way a clear distinction can be made on what was sent from the user and what was set by your code.
Important The most important paradigm shift from procedural to an MVC framework is that you NO LONGER will be talking to URL, FORM, REQUEST or any ColdFusion scope from within your handlers, layouts, and views. The request collection already has URL, FORM, and REQUEST scope capabilities, so leverage it.
The framework provides you with the relocate()
method that you can use to relocate to other events thanks to the framework super type object, the grand daddy of all things ColdBox.
Please see the for further investigation of all the goodness of methods you have available.
It is extremely important that you use this method when relocating instead of the native ColdFusion methods as it allows you to gracefully relocate to other events or external URIs. By graceful, we mean it does a lot more behind the scenes like making sure the flash scope is persisted, logging, post processing interceptions can occur and safe relocations.
So always remember that you relocate via relocate()
and if I asked you: "Where in the world does event handlers get this method from?", you need to answer: "From the super typed inheritance".
The event
object is the object that will let you set the views that you want to render, so please explore its API in the CFC Docs. To quickly set a view to render, do the following:
The view name is the name of the template in the views directory without appending the .cfm. If the view is inside another directory, you would do this:
The views you set will use the default layout defined in your configuration file which by default is the layouts/Main.cfm
We recommend that you set your views following the naming convention of your event. If your event is users.index, your view should be users/index. This will go a long way with maintainability and consistency and also will activate implicit views where you don't even have to use the set view method call.
You can also use the setView(), setLayout()
methods to tell the framework which view and layout combination to use:
You can also tell the framework to set a view for rendering by itself with no layout using the noLayout
argument
Here are the arguments for the setView()
method:
You can leverage the caching arguments in the setView()
method in order to render and cache the output of the views once the framework renders it. These cached views will be stored in the template cache region, which you can retrieve or purge by talking to it: getCache( 'template' )
.
Data can be passed from your handler to the view via rc or prc. If you want to pass data to a view without polluting rc and prc, you can pass it directly via the args parameter, much like a method call.
Access the data in the view like so:
If you don't want to, you don't have to. The framework gives you a method in the event object that you can use if this specific request should just terminate gracefully and not render anything at all. All you need to do is use the event object to call on the noRender()
method and it will present to the user a lovely white page of death.
All your handlers will be stored in the handlers folder of your application template. If you get to the point where your application needs even more decoupling and separation, please consider building instead.
You can also declare a HandlersExternalLocation
directive in your . This will be a dot notation path or instantiation path where more external event handlers can be found.
Event handlers are CFCs that will respond to FORM posts, HTTP requests and/or remote requests (like Flex,Air, SOAP, REST) via an incoming RC variable called event or by (Which we saw in the previous section).
You can also remove the inheritance from the CFC and WireBox will extend the coldbox.system.EventHandler
for you using .
Event Handlers are treated as singletons by ColdBox, so make sure you make them thread-safe and properly scoped. Persistence is controlled by the coldbox.handlerCaching
cachebox : A reference to the library (coldbox.system.cache.CacheFactory
)
logbox: A reference to the application (coldbox.system.logging.LogBox
)
log: A pre-configured logging (coldbox.system.logging.Logger
)
wirebox : A reference to the application (coldbox.system.ioc.Injector
)
Apart from executing events from the URL/FORM or Remote interfaces, you can also execute events internally, either public or private from within your event handlers or from interceptors, other handlers, layouts or views.
You do this by using the runEvent()
method which is inherited from our FrameworkSuperType
class. Here is the method signature:
The interesting aspect of internal executions is that all the same rules apply, so your handlers can return content like widgets, views, or even data. Also, the eventArguments enables you to pass arguments to the method just like method calls:
As you can see from the function signature you can tell ColdBox to cache the result of the event call. All of the cached content will go into the template cache by default unless you use the cacheProvider
argument. The cache keys are also based on the name of the event and the signature of the eventArguments
structure. Meaning, the framework can cache multiple permutations of the same event call as long as the eventArguments
are different.
Tip: You can disable event caching by using the coldbox.eventCaching
directive in your config/ColdBox.cfc
More often you will find that certain web operations need to be restricted in terms of what HTTP verb is used to access a resource. For example, you do not want form submissions to be done via GET but via POST or PUT operations. HTTP Verb recognition is also essential when building strong RESTFul APIs when security is needed as well.
You can do this manually, but why do the extra coding :)
This solution is great and works, but it is not THAT great. We can do better.
Another feature property on an event handler is called this.allowedMethods
. It is a declarative structure that you can use to determine what the allowed HTTP methods are for any action on the event handler.
If the request action HTTP method is not found in the approved list, it will look for a onInvalidHTTPMethod()
on the handler and call it if found. Otherwise ColdBox throws a 405 exception that is uniform across requests.
You can listen for global invalid HTTP methods using the coldbox.onInvalidHTTPMethodHandler
located in your config/ColdBox.cfc.
If the action is not listed in the structure, then it means that we allow all HTTP methods. Just remember to either use the onError()
or onInvalidHTTPMethod()
method conventions or an exception handler to deal with the security exceptions.
You can tag your event actions with a allowedMethods
annotation and add a list of the allowed HTTP verbs as well. This gives you a nice directed ability right at the function level instead of a property. It is also useful when leveraging DocBox documentation as it will show up in the API Docs that are generated.
Every event handler controller has some implicit methods that if you create them, they come alive. Just like the implicit methods in Application.cfc
With this convention you can create virtual events that do not even need to be created or exist in a handler. Every time an event requests an action from an event handler and that action does not exist in the handler, the framework will check if an onMissingAction()
method has been declared. If it has, it will execute it. This is very similar to ColdFusion's onMissingMethod()
but on an event-driven framework.
This event has an extra argument: missingAction which is the missing action that was requested. You can then do any kind of logic against this missing action and decide to do internal processing, error handling or anything you like. The power of this convention method is extraordinary, you have tons of possibilities as you can create virtual events on specific event handlers.
This is a localized error handler for your event handler. If any type of runtime error occurs in an event handler and this method exists, then the framework will call your method so you can process the error first. If the method does not exist, then normal error procedures ensue.
Please note that compile time errors will not fire this method, only runtime exceptions.
This method will be called for you if a request is trying to execute an action in your handler without the proper approved HTTP Verb. It will then be your job to determine what to do next:
You can pass localized arguments to the renderView() and renderLayout()
methods in order to encapsulate the rendering via the args
struct argument. Much like how you make method calls with arguments. Inside of your layouts and views you will receive the same args
struct reference as well.
This gives you great DRYness (yes that is a word) when building new and edit forms or views as you can pass distinct arguments to distinguish them and keep structure intact.
There are several simple implicit AOP (Aspect Oriented Programming) interceptor methods, usually referred to as advices, that can be declared in your event handler that the framework will use in order to execute them before/after and around an event as its fired from the current handler.
This is great for intercepting calls, pre/post processing, localized security, logging, RESTful conventions, and much more. Yes, you got that right, Aspect Oriented Programming just for you and without all the complicated setup involved! If you declared them, the framework will execute them.
Interceptor Method
Description
preHandler()
Executes before any requested action (In the same handler CFC)
pre{action}()
Executes before the {action}
requested ONLY
postHandler()
Executes after any requested action (In the same handler CFC)
post{action}()
Executes after the {action}
requested ONLY
aroundHandler()
Executes around any request action (In the same handler CFC)
around{action}()
Executes around the {action}
requested ONLY
Around advices are the most powerful of all as you completely hijack the requested action with your own action that looks, smells and feels exactly as the requested action. This is usually referred to as a proxy design pattern.
This will allow you to run both before and after advices but also surround the method call with whatever logic you want like transactions
, try/catch
blocks, locks
or even decide to NOT execute the action at all.
You can do it globally by using the aroundHandler()
method or targeted to a specific action around{actionName}()
.
Examples
The arguments received by these interceptors are:
event
: The request context reference
targetAction
: The function pointer to the action that got the around interception. It will be your job to execute it (Look at samples)
eventArguments
: The struct of extra arguments sent to an action if any
rc
: The RC reference
prc
: The PRC Reference
You can fine tune these interception methods by leveraging two public properties in the handler:
this.aroundhandler_only
: A list of actions that the aroundHandler()
action will fire ONLY!
this.aroundhandler_except
: A list of actions that the aroundHandler()
action will NOT fire on
We have a complete section dedicated to the Model Layer, but we wanted to review a little here since event handlers need to talk to the model layer all the time. By default, you can interact with your models from your event handlers in two ways:
Dependency Injection (Aggregation)
Request, use and discard model objects (Association)
ColdBox offers its own dependency injection framework, WireBox, which allows you, by convention, to talk to your model objects. However, ColdBox also allows you to connect to third-party dependency injection frameworks via the IOC module: http://forgebox.io/view/cbioc
Aggregation differs from ordinary composition in that it does not imply ownership. In composition, when the owning object is destroyed, so are the contained objects. - wikipedia
Your event handlers can be autowired with dependencies from WireBox by convention. By autowiring dependencies into event handlers, they will become part of the life span of the event handlers (singletons), since their references will be injected into the handler's variables
scope. This is a huge performance benefit since event handlers are wired with all necessary dependencies upon creation instead of requesting dependencies (usage) at runtime. We encourage you to use injection whenever possible.
Warning As a rule of thumb, inject only singletons into singletons. If not you can create unnecessary scope-widening injection issues and memory leaks.
You will achieve this in your handlers via property
injection, which is the concept of defining properties in the component with a special annotation called inject
, which tells WireBox what reference to retrieve via the WireBox Injection DSL. Let's say we have a users handler that needs to talk to a model called UserService. Here is the directory layout so we can see the conventions
Here is the event handler code to leverage the injection:
Notice that we define a cfproperty
with a name and inject
attribute. The name
becomes the name of the variable in the variables
scope and the inject
annotation tells WireBox what to retrieve. By default it retrieves model objects by name and path.
Tip: The injection DSL is vast and elegant. Please refer to it. Also note that you can create object aliases and references in your config binder: config/WireBox.cfc
The other approach to integrating with model objects is to request and use them as associations via the framework super type method: getInstance()
, which in turn delegates to WireBox's getInstance()
method. We would recommend requesting objects if they are transient (have state) objects or stored in some other volatile storage scope (session, request, application, cache, etc). Retrieving of objects is okay, but if you will be dealing with mostly singleton objects or objects that are created only once, you will gain much more performance by using injection.
Association defines a relationship between classes of objects that allows one object instance to cause another to perform an action on its behalf. - 'wikipedia'
In this practical example we will see how to integrate with our model layer via WireBox, injections, and also requesting the objects. Let's say that we have a service object we have built called FunkyService.cfc
and by convention we will place it in our applications models
folder.
FunkyService.cfc
Our funky service is not that funky after all, but it is simple. How do we interact with it? Let's build a Funky event handler and work with it.
By convention, I can create a property and annotate it with an inject
attribute. ColdBox will look for that model object by the given name in the models
folder, create it, persist it, wire it, and return it. If you execute it, you will get something like this:
Great! Just like that we can interact with our model layer without worrying about creating the objects, persisting them, and even wiring them. Those are all the benefits that dependency injection and model integration bring to the table.
You can use the value of the inject
annotation in several ways. Below is our recommendation.
Let's look at the requesting approach. We can either use the following approaches:
Via Facade Method
Directly via WireBox:
Both approaches do exactly the same thing. In reality getInstance()
does a wirebox.getInstance()
callback (Uncle Bob), but it is a facade method that is easier to remember. If you run this, you will also see that it works and everything is fine and dandy. However, the biggest difference between injection and usage can be seen with some practical math:
As you can see, the best performance is due to injection as the handler object was wired and ready to roll, while the requested approach needed the dependency to be requested. Again, there are cases where you need to request objects such as transient or volatile stored objects.
With this interceptor you can intercept local event actions and execute things after the requested action executes. You can do it globally by using the postHandler()
method or targeted to a specific action post{actionName}()
.
The arguments received by these interceptors are:
event
: The request context reference
action
: The action name that was intercepted
eventArguments
: The struct of extra arguments sent to an action if executed via runEvent()
rc
: The RC reference
prc
: The PRC Reference
You can fine tune these interception methods by leveraging two public properties in the handler:
this.posthandler_only
: A list of actions that the postHandler()
action will fire ONLY!
this.posthandler_except
: A list of actions that the postHandler()
action will NOT fire on
ColdBox provides you with a very simple but flexible and powerful layout manager and content renderer. You no longer need to create module tags or convoluted broken up HTML anymore. You can concentrate on the big picture and create as many layouts as your application needs. Then you can programmatically change rendering schemas (or skinning) and also create composite or component based views.
In this section we will explore the different rendering mechanisms that ColdBox offers and also how to utilize them. As you know, event handlers are our controller layer in ColdBox and we will explore how these objects can interact with the user in order to render content, whether HTML, JSON, XML or any type of rendering data.
Please note that you can use ColdBox as a pure API solution with modern JavaScript frameworks for the front end like VueJS, Reactor, Angular, etc.
Let's do a recap of our conventions for layouts and view locations:
It is imperative to know who does the rendering in ColdBox and that is the Renderer class that you can see from our diagram above. As you can tell from the diagram, it includes your layouts and/or views into itself in order to render out content. So by this association and inheritance all layouts and views have some variables and methods at their disposal since they get absorbed into the object. You can visit the API docs to learn about all the Renderer methods.
The Renderer is a transient object in order to avoid variable collisions, meaning it is recreated on each request. All of the following property members exist in all layouts and views rendered by the Renderer:
Property
Description
event
A reference to the Request Context object
rc
A reference to the request collection inside of the request context (For convenience)
prc
A reference to the private request collection inside of the request context (For convenience)
html
cacheBox
controller
A reference to the application's ColdBox Controller (coldbox.system.web.Controller)
flash
logbox
log
wirebox
As you can see, all views and layouts have direct reference to the request collections so it makes it incredibly easy to get and put data into it. Also, remember that the Renderer inherits from the Framework SuperType so all methods are at your disposal if needed.
You can also use the ColdBox Renderer in your models so you can render email templates, views, etc. We won't inject the renderer directly because remember that the renderer is a transient object. So we will use a WireBox feature called provider, which will inject a proxy placeholder that looks like the renderer and behaves like the renderer. But behinds the scene it takes care of the persistence. So you can just use it!
Views are HTML content that can be rendered inside of a layout or by themselves. They can be either rendered on demand or by being set by an event handler. Views can also produce any type of content apart from HTML like JSON/XML/WDDX via our view renderer that we will discover also. So get ready for some rendering goodness!
Usually, event handlers are the objects in charge of setting views for rendering. However, ANY object that has access to the request context object can do this also. This is done by using the setView()
method in the request context object.
Setting a view does not mean that it gets rendered immediately. It means that it is deposited in the request context. The framework will later on in the execution process pick those variables up and do the actual rendering. To do immediate rendering you will use the inline rendering methods describe later on.
We use the setView()
method to set the view views/general/index.cfm
to be rendered. Now the cool thing about this, is that we can override the view to be rendered anytime during the flow of the request. So the last process to execute the setView()
method is the one that counts. Also notice a few things:
No .cfm
extension is needed.
You can traverse directories by using /
like normal cfinclude
notation.
The view can exist in the conventions directory views
or in your configured external locations
You did not specify a layout for the view, so the application's default layout (main.cfm
) will be used.
It is best practice that view locations should simulate the event. So if the event is general.index, there should be a general folder in the root views folder with a view called index.cfm.
Let's look at the view code:
I am using our cool HTML Helper class that is smart enough to render tables, data, HTML 5 elements etc and even bind to ColdFusion ORM entities.
So what happens if I DO NOT want the view to be rendered within a layout? Am I doomed? Of course not, just use the same method with the noLayout
argument or event.noLayout()
method:
If you need the view to be rendered in a specific layout, then use the layout
argument or the setLayout()
method:
If you need the set a view to be rendered from a specific ColdBox Module then use the module
argument alongside any other argument combination:
You can also tell the renderer to not render back anything to the user by using the event.noRender()
method. Maybe you just took some input and need to gracefully shutdown the request into the infamous white screen of death.
You can also omit the explicit event.setView()
if you want, ColdBox will then look for the view according to the executing event's syntax by convention. So if the incoming event is called general.index
and no view is explicitly defined in your handler, ColdBox will look for a view in the general
folder called index.cfm
. That is why we recommend trying to match event resolution to view resolution even if you use or not implicit views.
Tip: This feature is more for conventions purists than anything else. However, we do recommend as best practice to use explicitly declare the view to be rendered when working with team environments as everybody will know what happens.
Caution If using implicit views, please note that the name of the view will ALWAYS be in lower case. So please be aware of this limitation. I would suggest creating URL Mappings with explicit event declarations so case and location can be controlled. When using implicit views you will also loose fine rendering control.
You can also disable implicit views by using the coldbox.implicitViews
configuration setting in your config/ColdBox.cfc
. This is useful as implicit lookups are time-consuming.
The ColdBox rendering engine can also be tweaked to use case-insensitive or sensitive implicit views by using the coldbox.caseSensitiveImplicitViews
directive in your config/ColdBox.cfc
. The default is to turn all implicit views to lower case, so the value is always false.
This is a nifty little feature that enables you to create nice helper templates on a per-view, per-folder and per-application basis. If the framework detects the helper, it will inject it into the rendering view so you can use methods, properties or whatever. All you need to do is follow a set of conventions. Let's say we have a view in the following location:
Then we can create the following templates
homeHelper.cfm
: Helper for the home.cfm view.
generalHelper.cfm
: Helper for any view in the general folder.
homeHelper.cfm
That's it. Just append Helper to the view or folder name and there you go, the framework will use it as a helper for that view specifically. What can you put in these helper templates:
NO BUSINESS CODE
UI logic functions or properties
Helper functions or properties
Dynamic JavaScript or CSS
Hint External views can also use our helper conventions
You can also use the coldbox.viewsHelper
directive to tell the framework what helper file to use for ALL views and layouts rendered:
ColdBox makes it easy to access the configuration stored in your Java system properties and your server's environment variables, even if you don't know which one it is in! Three methods are provided for your convenience:
config/ColdBox.cfc
or a ModuleConfig.cfc
If you are inside config/ColdBox.cfc
or a ModuleConfig.cfc
or a config/WireBox.cfc
you can use the three system settings functions directly! No additional work required.
Application.cfc
If you would like to access these methods in your Application.cfc
, create an instance of coldbox.system.core.util.Util
and access them off of that component. This is required when adding a datasource from environment variables.
Example:
A reference to the that can help you build interactive and safe HTML
A reference to the framework factory (coldbox.system.cache.CacheFactory)
A reference to the current configured Flash Object Implementation that inherits from the AbstractFlashScope (derived coldbox.system.web.flash.AbstractFlashScope)
The reference to the library (coldbox.system.logging.LogBox)
A pre-configured LogBox object for this specific class object (coldbox.system.logging.Logger)
A reference to the object factory (coldbox.system.ioc.Injector)
If you need to access these configuration values in other components, consider adding the values to your and injecting the values into your other components
Name
Arguments
Description
getSystemSetting
( key, defaultValue )
Looks for key
in properties first, env second. Returns the defaultValue
if neither exist.
getSystemProperty
( key, defaultValue )
Returns the Java System property for key
. Returns the defaultValue
if it does not exist.
getEnv
( key, defaultValue )
Returns the server environment variable for key
. Returns the defaultValue
if it does not exist.
Although we have access to all the HTTP verbs, modern browsers still only support GET and POST. With ColdBox and HTTP Method Spoofing, you can take advantage of all the HTTP verbs in your web forms.
By convention, ColdBox will look for an _method
field in the FORM scope. If one exists, the value of this field is used as the HTTP method instead of the method from the execution. For instance, the following block of code would execute with the DELETE action instead of the POST action:
You can manually add these _method
fields yourselves, or you can take advantage of ColdBox's HTML Helper startForm()
method. Just pass the method you like, we will take care of the rest:
ColdBox allows you to detect incoming extensions from incoming paths automatically for you. This is great for building multi-type responses or to just create virtual extensions for events.
If an extension is detected in the incoming URL, ColdBox will grab it and store it in the request collection (RC
) as the variable format
. If there is no extension, then rc.format
will not be stored and thus will not exist.
You can configure the extension detection using the following configuration methods:
Method
Description
setExtensionDetection( boolean )
By default ColdBox detects URL extensions like json, xml, html, pdf
which can allow you to build awesome RESTful web services. Default is true.
setValidExtensions( list )
Tell the interceptor what valid extensions your application can listen to. By default it listens to: json, jsont, xml, cfm, cfml, html, htm, rss, pdf
setThrowOnInvalidExtensions( boolean )
By default ColdBox does not throw an exception when an invalid extension is detected. If true, then the interceptor will throw a 406 Invalid Requested Format Extension: {extension} exception. Default is false.
Please note that if you have set to throw exceptions if an invalid extension is detected then a 406 exception will be thrown.
You can register routes in ColdBox with a human friendly name so you can reference them later for link generation and more.
You will do this in two forms:
Using the route()
method and the name
argument
Using the as()
method
You will generate URLs to named routes by leveraging the route()
method in the request context object (event).
Let's say you register the following named routes:
Then we can create routing URLs to them easily with the event.route()
method:
The request context object (event) also has some handy methods to tell you the name or even the current route that was selected for execution:
getCurrentRouteName()
- Gives you the name of the current route, if any
getCurrentRoute()
- Gives you the currently executed route
getCurrentRoutedURL()
- Gives you the complete routed URL pattern that matched the route
getCurrentRoutedNamespace()
- Gives you the current routed namespace, if any
Apart from routing by convention, you can also register your own expressive routes. Let's investigate the routing approaches.
The route()
method allows you to register a pattern and immediately assign it to execute an event or a response via the target argument.
The first pattern registers and if matched it will execute the wiki.page event. The second pattern if matched it will execute the profile.show event from the users module and register the route with the userprofile name.
You can also pass in a closure or lambda to the target argument and it will be treated as an inline action:
You can also pass just an HTML string with {rc_var}
replacements for the routed variables place in the request collection
to
EventsIf you will not use the inline terminators you can do a full expressive route definition to events using the to()
method, which allows you to concatenate the route pattern with modifiers:
You can also route to a handler and an action using the modifiers instead of the to()
method. This long-form is usually done for visibility or dynamic writing of routes. You can use the following methods:
withHandler()
withAction()
toHandler()
end()
You can also route to views and view/layout combinations by using the toView()
terminator:
You can also use the toRedirect()
method to re-route patterns to other patterns.
The default status code for redirects are 301 redirects which are PERMANENT redirects.
You can also redirect a pattern to a handler using the toHandler()
method. This is usually done if you have the action coming in via the URL or you are using RESTFul actions.
You can also route a pattern to HTTP RESTFul actions. This means that you can split the routing pattern according to incoming HTTP Verb. You will use a modifier withAction()
and then assign it to a handler via the toHandler()
method.
The Router allows you to create inline responses via closures/lambdas or enhanced strings to incoming URL patterns. You do not need to create handler/actions, you can put the actions inline as responses.
If you use a response closure/lambda, they each accepts three arguments:
event
- An object that models and is used to work with the current request (Request Context)
rc
- A struct that contains both URL/FORM
variables merged together (unsafe data)
prc
- A secondary struct that is private only settable from within your application (safe data)
If the response is an HTML string, then you can do {rc_var}
replacements on the strings as well:
You can also register routes that will respond to sub-domains and even capture portions of the sub-domain for multi-tenant applications or SaaS applications. You will do this using the withDomain()
method.
You can leverage the full routing DSL as long as you add the withDomain()
call with the domain you want to bind the route to. Also note that the domain string can contain placeholders which will be translated to RC
variables for you if matched.
Tip: Please note that you can leverage Routing Groups as well for domains
You can also add variables to the RC and PRC structs on a per-route basis by leveraging the following methods:
rc( name, value, overwrite=true )
- Add an RC
value if the route matched
rcAppend map, overwrite=true )
- Add multiple values to the RC
collection if the route matched
prc( name, value, overwrite=true )
- Add an PRC
value if the route matched
prcAppend map, overwrite=true )
- Add multiple values to the PRC
collection if the route matched
This is a great way to manually set variables in the incoming structures:
You can also apply runtime conditions to a route in order for it to be matched. This means that if the route matches the URL pattern then we will execute a closure/lambda to make sure that it meets the runtime conditions. We will do this with the withCondition(
) method.
Let's say you only want to fire some routes if they are using Firefox, or a user is logged in, or whatever.
We all need to deliver files to users at one point in time. ColdBox makes it easy to deliver any type of file even binary files via the Request Context's (event) sendFile()
method.
The API Docs can help you see the entire format of the method: https://apidocs.ortussolutions.com/coldbox/5.1.4/coldbox/system/web/context/RequestContext.html#sendFile()
The method signature is as follows:
Please note that the file
argument can be an absolute path or an actual binary file to stream out.
In ColdBox, you can register resourceful routes to provide automatic mappings between HTTP verbs and URLs to event handlers and actions by convention. By convention, all resources map to a handler with the same name or they can be customized if needed. This allows for a standardized convention when building routed applications.
You can leverage the resources()
method in your router to register resourceful routes.
This single resource declaration will create all the necessary variations of URL patterns and HTTP Verbs to actions to handle the resource. Please see the table below with all the permutations it will create for you.
For in-depth usage of the resources()
method, let's investigate the API Signature:
We have created a scaffolding command in CommandBox to help you register and generate resourceful routes. Just run the following command in CommandBox to get all the help you will need in generating resources:
Events are determined via a special variable that can be sent in via the FORM, URL, or REMOTELY called event
. If no event is detected as an incoming variable, the framework will look in the configuration directives for the DefaultEvent
and use that instead. If you did not set a DefaultEvent
setting then the framework will use the following convention for you: main.index
Hint : You can even change the event
variable name by updating the EventName
setting in your coldbox
configuration directive.
Please note that ColdBox supports both normal variable routing and URL mapping routing, usually referred to as pretty URLs.
In order to call them you will use the following event syntax notation format:
no event : Default event by convention is main.index
event={handler} : Default action method by convention is index()
event={handler}.{action} : Explicit handler + action method
event={package}.{handler}.{action} : Packaged notation
event={module}:{package}.{handler}.{action} : Module Notation (See ColdBox Modules)
This looks very similar to a Java or CFC method call, example: String.getLength(),
but without the parentheses. Once the event variable is set and detected by the framework, the framework will tokenize the event string to retrieve the CFC and action call to validate it against the internal registry of registered events. It then continues to instantiate the event handler CFC or retrieve it from cache, finally executing the event handler's action method.
Examples
With this interceptor you can intercept local event actions and execute things before the requested action executes. You can do it globally by using the preHandler()
method or targeted to a specific action pre{actionName}()
.
The arguments received by these interceptors are:
event
: The request context reference
action
: The action name that was intercepted
eventArguments
: The struct of extra arguments sent to an action if executed via runEvent()
rc
: The RC reference
prc
: The PRC Reference
Here are a few options for altering the default event execution:
Use event.overrideEvent('myHandler.myAction')
to execute a different event than the default.
Use event.noExecution()
to halt execution of the current event
You can fine tune these interception methods by leveraging two public properties in the handler:
this.prehandler_only
: A list of actions that preHandler()
will ONLY fire on
this.prehandler_except
: A list of actions that preHandler()
will NOT fire on
The framework also offers you the capability to bind incoming FORM/URL/REMOTE/XML/JSON/Structure data into your model objects by convention. This is done via capabilities. The easiest approach is to use our populateModel()
function which will populate the object from many incoming sources:
request collection RC
Structure
json
xml
query
This will try to match incoming variable names to setters or properties in your domain objects and then populate them for you. It can even do ORM entities with ALL of their respective relationships. Here is a snapshot of the method:
Let's do a quick example:
Person.cfc
editor.cfm
Event Handler -> person.cfc
In the dump you will see that the name
and email
properties have been bound.
A viewlet is a self sufficient view or a widget that can live on its own, its data is pre-fetched and can just be renderer anywhere in your system.
What in the world is this? Well, imagine a portal, in which each section of the portal is self-sufficient, with controls and data. You don't want to call all the handlers for this data for every single piece of content. It's not efficient, you need to create a separation. Well, a viewlet is such a separation that provides you with the ability to create reusable events. So how do we achieve this?
You will use the method runEvent()
anywhere you want a viewlet to be displayed or the content rendered. This calls an internal event that will be in charge to prepare and render the viewlet.
Create the portable event but make sure it returns the produced content.
This code just renders out the results of a runEvent()
method call. Please note that you can pass in arguments to the event using the eventArguments
argument. This makes the event act like a method call with arguments to ti. Remember that all events you call via runEvent()
will share the same RC/PRC.
I would suggest you look at to discover all arguments to the runEvent()
method call.
As you can see from the code above, the handler signature can accept arguments which are passed via the eventArguments
structure. It talks to a service layer and place some data on the private request collection the viewlet will use. It then returns the results of a renderView()
call that will render out the exact viewlet I want. You can be more creative and do things like:
render a layout + view combo
render data
return your own custom strings
etc
Caution We would suggest you namespace or prefix your private request collection variables for viewlets in order to avoid collisions from multiple viewlet events in the same execution thread or instead pass the necessary arguments into a view via the args
argument.
The view is a normal standard view, it doesn't even know it is a viewlet, remember, views are DUMB!
A content variable is a variable that contains HTML/XML or any kind of visual content that can easily be rendered anywhere. So instead of running the viewlet event in the view, you can abstract it to the controller layer and assign the output to a content variable:
So how do I render it?
Another example, is what if we do not know if the content variable will actually exist? How can we do this? Well, we use the event object for this and its magic getValue() method.
So now, if no content variable exists, an empty string will be rendered.
Important String manipulation in Java relies on immutable structures, so performance penalities might ensue. If you will be doing a lot of string manipulation, concatenation or rendering, try to leverage native java objects: StringBuilder or StringBuffer
Handler actions can return data back to its callers in different formats
Complex Data
HTML
Rendered Data via event.renderData()
By default, any complex data returned from handler actions will automatically be marshaled to JSON by default:
Simple as that. ColdBox detects the complex object and tries to convert it to JSON for you automatically.
renderdata
Action AnnotationIf you want ColdBox to marshall the content to another type like XML or PDF. Then you can use the renderdata
annotation on the action itself. The renderdata
annotation can be any of the following values:
json
jsonp
jsont
xml
html
text
renderdata
Component AnnotationYou can also add the renderData annotation to the component definition and this will override the default of JSON. So if you want XML as the default, you can do this:
If the returned complex data is an object and it contains a function called $renderData(),
then ColdBox will call it for you automatically. So instead of marshaling to JSON automatically, your object decides how to marshal itself.
By default if your handlers return simple values, then they will be treated as returning HTML.
Using the renderdata()
method of the event object is the most flexible for RESTFul web services or pure data marshaling. Out of the box ColdBox can marshall data (structs, queries, arrays, complex or even ORM entities) into the following output formats:
XML
JSON
JSONP
JSONT
HTML
TEXT
WDDX
CUSTOM
Here is the method signature:
Below are a few simple examples:
As you can see, it is very easy to render data back to the browser or caller. You can even choose plain and send HTML back if you wanted to.
You can also render out PDFs from ColdBox using the render data method. The data argument can be either the full binary of the PDF or simple values to be rendered out as a PDF; like views, layouts, strings, etc.
The renderData()
method also has two powerful arguments: formats & formatsView
. If you currently have code like this:
Where you need to param the incoming format extension, then do a switch and do some code for marshalling data into several formats. Well, no more, you can use our formats argument and ColdBox will marshall and code all that nasty stuff for you:
That's it! ColdBox will figure out how to deal with all the passed in formats for you that renderdata
can use. By convention it will use the name of the incoming event as the view that will be rendered for HTML and PDF; implicit views. If the event was users.list, then the view would be views/users/list.cfm. However, you can tell us which view you like if it is named different:
If you need to redirect for html events, you can pass any arguments you normally would pass to setNextEvent
to formatsRedirect
.
You can do custom data conversion by convention when marshalling CFCs. If you pass in a CFC as the data
argument and that CFC has a method called $renderdata()
, then the marshalling utility will call that function for you instead of using the internal marshalling utilities. You can pass in the custom content type for encoding as well:
The CFC converter:
In this approach your $renderdata()
function can be much more customizable than our internal serializers. Just remember to use the right contentType argument so the browser knows what to do with it.
See the documentation for more details.
There is also a pdfArgs
argument in the render data method that can take in a structure of name-value pairs that will be used in the cfdocument
() tag when generating the PDF. This is a great way to pass in arguments to really control the way PDF's are generated uniformly.
So what if I want to render a view outside of my application without using the setting explained above? Well, you use the renderExternalView()
method.
ColdBox Core MVC does not have validation built-in but it is implemented via the offical core cbValidation
module. You can easily install the module in your application via:
You can find much more information about this module in the following resources:
Documentation: https://github.com/coldbox-modules/cbox-validation/wiki
ForgeBox : http://forgebox.io/view/cbvalidation
We have now seen how to set views to be rendered from our handlers. However, we can use some cool methods to render views and layouts on-demand. These methods exist in the Renderer and several facade methods exist in the super type so you can call it from any handler, interceptor, view or layout.
renderView()
renderExternalView()
renderLayout()
Check out the latest API Docs for the latest arguments:
Inline renderings are a great asset for reusing views and doing layout compositions
If you need rendering capabilities in your model layer, we suggest using the following injection DSL:
This will inject a provider of a Renderer into your model objects. Remember that renderers are transient objects so you cannot treat them as singletons. The provider is a proxy to the transient object, but you can use it just like the normal object:
A part from using runEvent()
to execute events, you can also abstract it by using the runRoute()
method. This method is fairly similar but with the added benefit of executing a NAMED route instead of the direct event it represents. This gives you the added flexibility of abstracting the direct event and leveraging the named route.
All the same feature of runEvent()
apply to runRoute()
Just like you can create links based on named routes and params, you can execute named routes and params as well internally via runRoute()
The params argument you pass to the runRoute() method will be translated into event arguments. Therefore they will be passed as arguments to the event the route represents:
In the example above, the userData
named route points to the user.data
event.
If you want to execute module routes, no problem! Just use our @ or :
notation to tell the controller from which module's router we should pick the route from.
You can also pass in the caching arguments below and your view will be rendered once and then cached for further renderings. Every ColdBox application has two active cache regions: default and template
. All view and event caching renderings go into the template
cache.
Argument
Type
Required
Default
Description
cache
boolean
false
false
Cache the view to be rendered
cacheTimeout
numeric
false
(provider default)
The timeout in minutes or whatever the cache provider defines
cacheLastAccessTimeout
numeric
false
(provider default)
The idle timeout in minutes or whatever the cache provider defines
cacheSuffix
string
false
---
Adds a suffix key to the cached key. Used for providing uniqueness to the cacheable entry
So now that our views are cached, how do I purge them programmatically? Well, you need to talk to the template
cache provider and use the clearing methods:
Then we can perform several operations on views:
clearView(string viewSnippet)
: Used to clear a view from the cache by using a snippet matched according to name + cache suffix.
clearMultiView(any viewSnippets)
: Clear using a list or array of view snippets.
clearAllViews([boolean async=true])
: Can clear ALL cached views in one shot and can be run asynchronously.
To turn off view caching for your entire application, set the viewCaching
setting to false in your config/Coldbox.cfc
config file.
Event caching is extremely useful and easy to use. ColdBox will act like a cache proxy between your events and the clients requesting the events, much like squid, nginx or HA Proxy. All you need to do is add several metadata arguments to the action methods and the framework will cache the output of the event in the template cache provider in CacheBox. In other words, the event executes and produces output that the framework then caches. Subsequent calls to the same event with the same incoming RC variables will not do any processing, but just output the content back to the user.
For example, you have an event called blog.showEntry
. This event executes, gets an entry from the database and sets a view to be rendered. The framework then renders the view and if event caching is turned on for this event, the framework will cache the HTML produced. So the next incoming show entry event will just spit out the cached HTML. The cache key is created by hashing the incoming request collection.
Important to note also, that any combination of URL/FORM parameters on an event will produce a unique cacheable key. So event=blog.showEntry&id=1
& event=blog.showEntry&id=2
are two different cacheable events.
To enable event caching, you will need to set a setting in your ColdBox.cfc
called coldbox.eventcaching
to true
.
Important Enabling event caching does not mean that ALL events will be cached. It just means that you enable this feature.
The way to set up an event for caching is on the function declaration with the following annotations:
Annotation
Type
Description
cache
boolean
A true or false will let the framework know whether to cache this event or not. The default is FALSE. So setting to false makes no sense
cachetimeout
numeric
The timeout of the event's output in minutes. This is an optional attribute and if it is not used, the framework defaults to the default object timeout in the cache settings. You can place a 0 in order to tell the framework to cache the event's output for the entire application timeout controlled by coldfusion, NOT GOOD. Always set a decent timeout for content.
cacheLastAccesstimeout
numeric
The last access timeout of the event's output in minutes. This is an optional attribute and if it is not used, the framework defaults to the default last access object timeout in the cache settings. This tells the framework that if the object has not been accessed in X amount of minutes, then purge it.
cacheProvider
string
The cache provider to store the results in. By default it uses the template cache.
Important Please be aware that you should not cache output with 0 timeouts (forever). Always use a timeout.
Alert: DO NOT cache events as unlimited timeouts. Also, all events can have an unlimited amount of permutations, so make sure they expire and you purge them constantly. Every event + URL/FORM variable combination will produce a new cacheable entry.
All event and view caching are stored in a named cache called template
which all ColdBox applications have by default. You can open or create a new CacheBox configuration object and decide where the storage is, timeouts, providers, etc. You have complete control of how event and view caching is stored.
We also have a great way to purge these events programmatically via our cache provider interface.
Methods for event purging:
clearEvent( string eventSnippet, string querystring="" )
: Clears all the event permutations from the cache according to snippet and querystring. Be careful when using incomplete event name with query strings as partial event names are not guaranteed to match with query string permutations
clearEventMulti( eventsnippets,string querystring="" )
: Clears all the event permutations from the cache according to the list of snippets and querystrings. Be careful when using incomplete event name with query strings as partial event names are not guaranteed to match with query string permutations
clearAllEvents( [boolean async=true] )
: Can clear ALL cached events in one shot and can be run asynchronously.
You can now leverage the cache suffix property in handlers to be declared as a closure so it can be evaluated at runtime so it can add dynamic suffixes to cache keys. This can allow you to incorporate elements into the cache key at runtime instead of statically. This is a great way to incorporate the user's language locale or session identifier to make unique entries.
OnRequestCapture
- Influence Cache KeysWe have provided an interception point in ColdBox that allows you to add variables into the request collection before a snapshot is made so you can influence the cache key of a cacheable event. What this means is that you can use it to mix in variables into the request collection that can make this event cache unique for a user, a specific language, country, etc. This is a great way to leverage event caching on multi-lingual or session based sites.
With the simple example above, the user's locale will be addded to all your event caching permutations and thus create entries for different languages.
Several event interception points are NOT available during event caching.
When using event caching the framework will NOT execute ANY event at all. It will stream the content directly from the selected cache provider. This means that any interceptors or code that executes in the event is also NOT executed. The only interception points that will execute are:
preProcess
postProcess
So please make sure you take note of this when planning for event security.
CacheBox has an intuitive and powerful monitor that can be used via the ColdBox Debugger Module. From the monitor you can purge, expire and view cache elements, etc.
You have a few arguments in the renderView()
method that deal with collection rendering. Meaning you can pass any array or query and the Renderer will iterate over that collection and render out the view as many times as the records in the colleciton.
collection
: A data collection that can be a query or an array of objects, structs or whatever
collectionAs
: The name of the variable in the variables scope that will hold the collection pivot.
collectionStartRow
: Defaults to 1 or your offset row for the collection rendering
collectionMaxRows
: Defaults to show all rows or you can cap the rendering display
collectionDelim
: An optional delimiter to use to separate the collection renderings. By default it is empty.
Once you call renderView()
with a collection, the renderer will render the view once for each member in the collection. The views have access to the collection via arguments.collection or the member currently iterating. The name of the member being iterated as is by convention the same name as the view. So if we do this in any layout or simple view:
Then the tags/comment
will be rendered as many times as the collection rc.comments
has members on it and by convention the name of the variable is comment the same as the view name.
If you don't like that, then use the collectionAs argument:
So let's see the collection view now:
You can see that I just call methods on the member as if I was looping (which we are for you). But you will also see two little variables here:
_counter
: A variable created for you that tells you in which record we are currently looping on
_items
: A variable created for you that tells you how many records exist in the collection
This will then render that specific dynamic HTML view as many times as their are records in the rc.comments array and concatenate them all for you. In my case, I separate each iteration with a simple but you can get fancy and creative.
All rendered views have associated events that are announced whenever the view is rendered via ColdBox Interceptors. These are great ways for you to be able to intercept when views are rendered and transform them, append to them, or even remove content from them in a completely decoupled approach. The way to listen for events in ColdBox is to write Interceptors, which are essential simple CFC's that by convention have a method that is the same name as the event they would like to listen to. Each event has the capability to receive a structure of information wich you can alter, append or remove from. Once you write these Interceptors you can either register them in your Configuration File or programmatically.
Caution You can disable the view events on a per-rendering basis by passing the
prePostExempt
argument as true when callingrenderView()
methods.
Here is a sample interceptor that trims any content before it is renderer:
Of course, I am pretty sure you will be more creative than that!
