Last Updated : 28 Apr, 2025

Ember.js is an open-source JavaScript framework used for developing large client-side web applications which is based on Model-View-Controller (MVC) architecture. Ember.js is one of the most widely used front-end application frameworks. It is made to speed up development and increase productivity. Currently, it is utilized by a large number of websites, including Square, Discourse, Groupon, Linked In, Live Nation, Twitch, and Chipotle.

The replaceWith() method of the RouterService is used to replace the current route with a new route in the application's URL history. This method works similarly to the transitionTo() method, but instead of adding a new entry to the history, it replaces the current entry.

Syntax:

this.router.replaceWith(routeName, models, options );

Parameters:

routeName: It is the URL for the desired location.
model: It is an object of params to pass to the destination route.
options: It is a hash containing queryParams property.

Return type: Transition object associated with the transition.
