Command

Commands as classes can use ember's dependency injection system as much as ember developers are used to. That's what the Command base class is for. Here is how we write our command from above with access to the data layer (an ember service) to fire off a command to the backend:

import { inject as service } from '@ember/service';
import { Command } from 'ember-command';
import DataService from 'super-rentals/services/data';

export default class RequestOfferCommand extends Command {
  @service declare data: DataService;

  execute(): void {
    this.data.sendCommand('super-rentals.recommendations.request-offer', {...});
  }
}
