ng Social Login

This is the refrenced library from ng4-social-login.

Social login and authentication module for Angular 4. Supports authentication with Google, Linkedin and Facebook.

Main Feature

This will also return a token (for Facebook and Google) and code (for Linked In) along with profile detail so that logged in user from client side can also be verified on server side.

Getting started

Documentation

Install via npm

npm install --save ng-social-login

Import the module

In your AppModule, import the SocialLoginModule

import {
  SocialLoginModule,
  AuthServiceConfig,
  GoogleLoginProvider,
  FacebookLoginProvider,
  LinkedinLoginProvider
} from 'ng-social-login';

const CONFIG = new AuthServiceConfig([
  {
    id: GoogleLoginProvider.PROVIDER_ID,
    provider: new GoogleLoginProvider('Google-OAuth-Client-Id')
  },
  {
    id: FacebookLoginProvider.PROVIDER_ID,
    provider: new FacebookLoginProvider('Facebook-App-Id')
  },
  {
    id: LinkedinLoginProvider.PROVIDER_ID,
    provider: new LinkedinLoginProvider('LINKEDIN_CLIENT_ID')
  }
]);

export function provideConfig() {
  return CONFIG;
}

@NgModule({
  declarations: [
    ...
  ],
  imports: [
    ...
    SocialLoginModule
  ],
  providers: [
    {
      provide: AuthServiceConfig,
      useFactory: provideConfig
    }
  ],
  bootstrap: [...]
})
export class AppModule { }

Sign in and out users

import {
  AuthService
  FacebookLoginProvider,
  GoogleLoginProvider,
  LinkedinLoginProvider
} from 'ng-social-login';

@Component({
  selector: 'app-demo',
  templateUrl: './demo.component.html',
  styleUrls: ['./demo.component.css']
})
export class DemoComponent implements OnInit {

  constructor(private authService: AuthService) { }

  signInWithGoogle(): void {
    this.authService.signIn(GoogleLoginProvider.PROVIDER_ID);
  }

  signInWithFB(): void {
    this.authService.signIn(FacebookLoginProvider.PROVIDER_ID);
  }

  signInWithLinkedIN(): void {
    this.authService.signIn(LinkedinLoginProvider.PROVIDER_ID);
  }

  signOut(): void {
    this.authService.signOut();
  }

}

Subscribe to the authentication state

You are notified when user logs in or logs out. You receive a SocialUser object when the user logs in and a null when the user logs out. SocialUser object contains basic user information such as name, email, photo URL, etc.

import { AuthService } from 'ng-social-login';
import { SocialUser } from 'ng-social-login';

@Component({
  selector: 'app-demo',
  templateUrl: './demo.component.html',
  styleUrls: ['./demo.component.css']
})
export class DemoComponent implements OnInit {

  private user: SocialUser;
  private loggedIn: boolean;

  constructor(private authService: AuthService) { }

  ngOnInit() {
    this.authService.authState.subscribe((user) => {
      this.user = user;
      this.loggedIn = (user != null);
    });
  }

}

Display the user information

<img src='{{ user.photoUrl }}'>
<div>
  <h4>{{ user.name }}</h4>
  <p>{{ user.email }}</p>
</div>
