Routing
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.// Old Style
http://localhost/index.cfm?event=home.about&page=2
http://localhost/index.cfm?city=24&page=3&county=234324324
// New Routing Style
http://localhost/home/about/page/2
http://localhost/dade/miami/page/3
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
config/Router.cfc
function configure(){
// Routing with placeholders to an event with placeholders
route( "/blog/:year-numeric{4}/:month?/:day?" )
.to( "blog.list" );
// Redirects
route( "/old/book" )
.toRedirect( "/mybook" );
// Responses
route( "/echo" ).toResponse( (event,rc,prc) => {
return "hello luis";
} );
// Shortcut to above
route( "/echo", (event,rc,prc) => {
return "hello luis";
} );
// Show view
route( "/contact-us" )
.toView( "main/contact" );
// Direct to handler with action from URL
route( "/users/:action" )
.toHandler( "users" );
// Inline pattern + target and name
route( pattern="/wiki/:page", target="wiki.show", name="wikipage" );
}
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.
