Application Router

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 API Docs 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.

Application Router - Router.cfc

config/Router.cfc
component {

	function configure() {
		// Set Full Rewrites
		setFullRewrites( true );

		/**
		 * --------------------------------------------------------------------------
		 * App Routes
		 * --------------------------------------------------------------------------
		 *
		 * Here is where you can register the routes for your web application!
		 * Go get Funky!
		 *
		 */

		// A nice healthcheck route example
		route( "/healthcheck", function( event, rc, prc ) {
			return "Ok!";
		} );

		// A nice RESTFul Route example
		route( "/api/echo", function( event, rc, prc ) {
			return {
				"error" : false,
				"data"  : "Welcome to my awesome API!"
			};
		} );

		route(
			pattern : "/api/contacts",
			target  : "contacts.index",
			name    : "api.contacts"
		);

		// Conventions based routing
		route( ":handler/:action?" ).end();
	}

}

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:

  1. Configuring the Router

  2. Adding Routes via the Routing DSL

Router as an Interceptor

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.

Generated Settings

Once the routing service loads your Router it will create several application settings for you:

  • SesBaseUrl : The multi-domain URL base URL of your application: http://localhost

  • SesBasePath : The multi-domain path with no protocol or host

  • HtmlBaseUrl : The same path as SESBaseURLbut 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.

  • HtmlBasePath : Does not include protocol or host

Configuration Methods

You can use the following methods to fine tune the configuration and operation of the routing services:

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.

setBaseURL( string )

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.

setMultiDomainDiscovery( boolean )

Defaults to true. With this setting on, every request will be inspected for the incoming host for usage in building links and domain detection.

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.

function configure(){

    setFullRewrites( true );
    setExtensionDetection( true );
    setValidExtensions( "json,cfm,pdf" );
    setMultiDomainDiscovery( false )

}

The next sections will discus how to register routes for your application.
