How do services help in implementing the Facade Pattern in Angular applications

Question

Can i know How do services help in implementing the Facade Pattern in Angular applications?

Answer 1

In Angular, services help implement the Facade Pattern by acting as a single interface that hides complex logic and coordinates interactions between multiple components, APIs, or state management layers.

Example:

// user-facade.service.ts

@Injectable({ providedIn: 'root' })

export class UserFacade {

  constructor(private api: UserService, private auth: AuthService) {}

  loginUser(credentials) {

    return this.auth.login(credentials);

  }

  getUserProfile() {

    return this.api.fetchProfile();

  }

}
