Backbone Marionette - route handling inside modules

App.coffee

TodoModule  = require './modules/todo/TodoModule'

class App extends Backbone.Marionette.Application
  initialize: =>
    @router = new Backbone.Marionette.AppRouter

    @module('Todo', TodoModule)

    @addInitializer( (options) =>
      Backbone.history.start();
    )

    @start()

module.exports = new App()

TodoController.coffee

module.exports = class TodoController
  index: ->
    # routed to home, handled in another object

TodoModule.coffee

TodoController = require './TodoController'

module.exports = class TodoModule extends BaseModule
  initialize: ->
    @startWithParent = true
    
    @controller = new TodoController()

    # use TodoModule as controller
    @app.router.processAppRoutes @,
      'home': 'index'

    # OR

    # use another object as controller
    @app.router.processAppRoutes @controller,
      'home': 'index'

      
  index: ->
    # routed to home

This way you can also distribute routes amongst Marionette modules, so that each module will add only the ones it needs.
