Ember/5/Deprecate Router Events

Last update

Jan 10, 2025

This codemod removes all calls to willTransition or didTransition events on the Router via usage of routeWillChange event listener and routeDidChange event listener.

Before

import Router from "@ember/routing/router";
import { inject as service } from "@ember/service";

export default Router.extend({
  currentUser: service("current-user"),

  willTransition(transition) {
    this._super(...arguments);
    if (!this.currentUser.isLoggedIn) {
      transition.abort();
      this.transitionTo("login");
    }
  },

  didTransition(privateInfos) {
    this._super(...arguments);
    ga.send("pageView", {
      pageName: privateInfos.name,
    });
  },
});

After

import Router from "@ember/routing/router";
import { inject as service } from "@ember/service";

export default Router.extend({
  currentUser: service("current-user"),

  init() {
    this._super(...arguments);

    this.on("routeWillChange", (transition) => {
      if (!this.currentUser.isLoggedIn) {
        transition.abort();
        this.transitionTo("login");
      }
    });

    this.on("routeDidChange", (transition) => {
      ga.send("pageView", {
        pageName: privateInfos.name,
      });
    });
  },
});
