Best Practices

• Use resource for async data

import { resource } from '@angular/core/rxjs-interop';

@Component({})
export class MyComponent {
  private http = inject(HttpClient);
  
  users = resource({
    loader: () => this.http.get<User[]>('/api/users').toPromise()
  });
}

• Use with request

id = signal<string>('');

user = resource({
  request: () => ({ id: this.id() }),
  loader: ({ request }) => this.http.getUser(request.id).toPromise()
});
