Angular4 Social Login

Social login and authentication module for Angular 4. Supports authentication with Google and Facebook. Can be extended to other providers also.

Forked from EasyApps Co.

Getting started

Install via npm

npm install --save angular4-oauth-login

Import the module

In your AppModule, import the SocialLoginModule

import { SocialLoginModule, AuthServiceConfig } from "angular4-oauth-login";
import { GoogleLoginProvider, FacebookLoginProvider } from "angular4-oauth-login";

let config = new AuthServiceConfig([
  {
    id: GoogleLoginProvider.PROVIDER_ID,
    provider: new GoogleLoginProvider("Google-OAuth-Client-Id", 'email picture')
  },
  {
    id: FacebookLoginProvider.PROVIDER_ID,
    provider: new FacebookLoginProvider("Facebook-App-Id")
  }
]);

@NgModule({
  declarations: [
    ...
  ],
  imports: [
    ...
    SocialLoginModule.initialize(config)
  ],
  providers: [],
  bootstrap: [...]
})
export class AppModule { }

Sign in and out users

import { AuthService } from "angular4-oauth-login";
import { FacebookLoginProvider, GoogleLoginProvider } from "angular4-oauth-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);
  }

  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 "angular4-oauth-login";
import { SocialUser } from "angular4-oauth-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>
