How to use the angular-formio/resource.FormioResourceRoutes function in angular-formio

// provide our own Event resource page.
@Component({
  styles: [
    'ul.nav.nav-tabs { margin-bottom: 20px; }',
    '.resource-back-icon { font-size: 1.2em; padding: 0.6em; }'
  ],
  template: require('./event.html')
})
export class EventResourceComponent extends FormioResourceComponent {
  constructor(public service: FormioResourceService, public route: ActivatedRoute) {
    super(service, route);
  }
}

// add the Activity nested resource.
let eventResourceRoutes: Routes = FormioResourceRoutes({
  resource: EventResourceComponent
});
eventResourceRoutes[2].children.push({
  path: 'activity',
  loadChildren: 'es6-promise-loader?,[name]!../activity/activity.module#ActivityResource'
});
