EmberJS - Router


Advertisements


Router is a core feature of EmberJs which translates an URL into a series of templates and represents the state of an application.The Ember uses the router to map the URL to a route handler. The router matches the current URL to other routes which are used for loading data, displaying the templates and to set up an application state.

Route handler performs some actions such as −

  • It provides the template.

  • It defines the model and it will be accessible to the template.

  • If there is no permission for user to visit the particular part of an app, then router will redirect to a new route.

The following table lists down the different routers in Ember.js along with their description −
