API Reference

extend Router.extend(properties)

Get started by creating a custom router class. Define actions that are triggered when certain URL are matched, and provide a routes hash that pairs routes to actions. Note that you'll want to avoid using a leading slash in your route definitions:

var UserRouter = Router.extend({
 
  routes: {
    "users|get":                 "all",    // /users
    "users/:id|get":        "show",  // /users/11
  },
 
  before_filters: {
    "users|get":                 "all",    // this filter will run before /users
    "users/:id|get":        "show",  // this filter will run before /users/11
  },
 
  all: function(request,response,next) {
    //...
  },
 
  show: function(request,response,next) {
    //...
  },
 
  beforeAll: function(request,response,next) {
    //...
    next(); //dont forget to call next()
  },
 
  beforeShow: function(request,response,next) {
    //...
    next(); //dont forget to call next()
  }
 
});

routers router.routes

The routes hash maps URLs with parameters to functions on your router. Routes can contain path parameter parts, :param.

routers router.before_filters

The before filters hash maps URLs with parameters to functions on your router. Route filters can contain path parameter parts, :param.

constructor / initialize new Router([options])

When creating a new router, you must pass an instance of express application which this router will be mounted into and additional express router options.
