Once the addon is installed, the cable service can be injected wherever needed in the application.

// app/controllers/application.js
import Ember from 'ember';
 
export default Ember.Controller.extend({
  cableService: Ember.inject.service('cable'),
  consumer: null,
 
  setupConsumer: Ember.on('init', function() {
    var consumer = this.get('cableService').createConsumer('ws://localhost:4200/cable');
 
    consumer.subscriptions.create("NotificationChannel", {
      connected() {
        this.perform('hello', { foo: 'bar' });
        this.perform('hello');
      },
      received(data) {
        Ember.debug( "received(data) -> " + Ember.inspect(data) );
      },
      disconnected() {
        Ember.debug("NotificationChannel#disconnected");
      }
    });
 
    // Passing Parameters to Channel
    const subscription = consumer.subscriptions.create({ channel: 'NotificationChannel', room: 'Best Room' }, {
      received: (data) => {
        this.updateRecord(data);
      }
    });
 
    // Using mixin and inject your services
    var channelMixin = Ember.Mixin.create({
      store: Ember.inject.service(),
 
      received(data) {
        this.get("store").pushPayload(data);
      }
    });
 
    consumer.subscriptions.create({ channel: 'NotificationChannel' }, channelMixin);
 
    // Send actions to your Action Cable channel class
    subscription.perform("your_channel_action", { hey: "hello" });
 
    // Save consumer to controller to link up computed props
    this.set('consumer', consumer);
  }),
 
  updateRecord(data) {
    Ember.debug( "updateRecord(data) -> " + Ember.inspect(data) );
  },
 
  // Flag indicating a connection is being attempted
  isConnecting: Ember.computed.readOnly('consumer.isConnecting'),
 
  // Milliseconds until the next connection attempt
  nextConnectionAt: Ember.computed.readOnly('consumer.nextConnectionAt'),
});
