Getting started

Install via npm

npm i @abacritt/angularx-social-login

Import the module

In your AppModule, import the SocialLoginModule

import { SocialLoginModule, SocialAuthServiceConfig } from '@abacritt/angularx-social-login';
import {
  GoogleLoginProvider,
  FacebookLoginProvider
} from '@abacritt/angularx-social-login';

@NgModule({
  declarations: [
    ...
  ],
  imports: [
    ...
    SocialLoginModule
  ],
  providers: [
    {
      provide: 'SocialAuthServiceConfig',
      useValue: {
        autoLogin: false,
        providers: [
          {
            id: GoogleLoginProvider.PROVIDER_ID,
            provider: new GoogleLoginProvider(
              'clientId'
            )
          },
          {
            id: FacebookLoginProvider.PROVIDER_ID,
            provider: new FacebookLoginProvider('clientId')
          }
        ],
        onError: (err) => {
          console.error(err);
        }
      } as SocialAuthServiceConfig,
    }
  ],
  bootstrap: [...]
})
export class AppModule { }

Sign in and out users

import { SocialAuthService } from "@abacritt/angularx-social-login";
import { FacebookLoginProvider } from "@abacritt/angularx-social-login";

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

  constructor(private authService: SocialAuthService) { }

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

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

}

Sign in with google

GoogleLoginProvider has no signIn() method as other providers, the login flow is triggered by a button that the gis client is generating. Calling SocialAuthService.signIn(GoogleLoginProvider.PROVIDER_ID) will have no effect.

Instead make sure you subscribed to the authentication state and add the following GoogleSigninButtonDirective (exported from the GoogleSigninButtonModule) to your component template to wrap the 'Sign In With Google' button:

ALSO

Check out the Google button generator. Link to Button attributes

<asl-google-signin-button type='icon' size='medium'></asl-google-signin-button>

Options:

Name Type Value Default
type string 'icon' or 'standard' 'icon'
size string 'small', 'medium' or 'large' 'medium'
shape string 'square','circle','pill' or 'rectangular' 'rectangular'
text string 'signin_with','signup_with'or 'continue_with' 'signin_with'
width string '200 - 400 '
theme string 'outline','filled_blue' or 'filled_black' 'outline'
logo_alignment string 'left' or 'center' 'left'

This will only work if the GoogleLoginProvider is registered in SocialAuthServiceConfig.

Refresh google Auth Token

Once a user is logged in manual refresh token method can be triggered

import { SocialAuthService } from "@abacritt/angularx-social-login";
import { GoogleLoginProvider } from "@abacritt/angularx-social-login";

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

  constructor(private authService: SocialAuthService) { }

  refreshToken(): void {
    this.authService.refreshAuthToken(GoogleLoginProvider.PROVIDER_ID);
  }

}

Request google Access Token

Once a user is logged in an access token can be requested for the scopes we specified in GoogleInitOptions.scopes, you can then reuse this access token to make calls to google apis

import { HttpClient } from '@angular/common/http';
import { SocialAuthService } from "@abacritt/angularx-social-login";
import { GoogleLoginProvider } from "@abacritt/angularx-social-login";

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

  private accessToken = '';

  constructor(private authService: SocialAuthService, private httpClient: HttpClient) { }

  getAccessToken(): void {
    this.authService.getAccessToken(GoogleLoginProvider.PROVIDER_ID).then(accessToken => this.accessToken = accessToken);
  }

  getGoogleCalendarData(): void {
    if (!this.accessToken) return;

    this.httpClient
      .get('https://www.googleapis.com/calendar/v3/calendars/primary/events', {
        headers: { Authorization: `Bearer ${this.accessToken}` },
      })
      .subscribe((events) => {
        alert('Look at your console');
        console.log('events', events);
      });
  }
}

Refresh google Access Token

Once a user is logged in and an access token was obtained, the access token can be refreshed (revoked)

import { SocialAuthService } from "@abacritt/angularx-social-login";
import { GoogleLoginProvider } from "@abacritt/angularx-social-login";

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

  constructor(private authService: SocialAuthService) { }

  refreshToken(): void {
    this.authService.refreshAccessToken(GoogleLoginProvider.PROVIDER_ID);
  }

}

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. along with the auth_token. You can communicate the auth_token to your server to authenticate the user in server and make API calls from server.

import { SocialAuthService } from "@abacritt/angularx-social-login";
import { SocialUser } from "@abacritt/angularx-social-login";

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

  user: SocialUser;
  loggedIn: boolean;

  constructor(private authService: SocialAuthService) { }

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

}

Display the user information

<img src="{{ user.photoUrl }}" referrerpolicy="no-referrer">
<div>
  <h4>{{ user.name }}</h4>
  <p>{{ user.email }}</p>
</div>

Custom Provider

We can use a custom provider, implementing our own logic and needs like the following example:

@Injectable({ providedIn: 'root' })
export class MyCustomLoginProvider extends BaseLoginProvider {
  public static readonly PROVIDER_ID = 'CUSTOM' as const;

  constructor(/* infinite list of dependencies*/) {}
}
@NgModule({
  declarations: [AppComponent, NavbarComponent, DemoComponent],
  imports: [BrowserModule, FormsModule, SocialLoginModule],
  providers: [
    {
      provide: 'SocialAuthServiceConfig',
      useValue: {
        autoLogin: true,
        providers: [
          {
            id: MyCustomLoginProvider.PROVIDER_ID,
            provider: MyCustomLoginProvider,
          },
        ],
      } as SocialAuthServiceConfig,
    },
  ],

Specifying custom scopes, fields etc. on initialization

const fbLoginOptions = {
  scope: 'pages_messaging,pages_messaging_subscriptions,email,pages_show_list,manage_pages',
  return_scopes: true,
  enable_profile_selector: true
}; // https://developers.facebook.com/docs/reference/javascript/FB.login/v2.11

const googleLoginOptions: GoogleInitOptions = {
  oneTapEnabled: false, // default is true
  scopes: 'https://www.googleapis.com/auth/calendar.readonly'
}; // https://developers.google.com/identity/oauth2/web/guides/use-token-model#initialize_a_token_client

const vkLoginOptions = {
  fields: 'photo_max,contacts', // Profile fields to return, see: https://vk.com/dev/objects/user
  version: '5.124', // https://vk.com/dev/versions
}; // https://vk.com/dev/users.get

let config = [
  {
    id: GoogleLoginProvider.PROVIDER_ID,
    provider: new GoogleLoginProvider("Google-OAuth-Client-Id", googleLoginOptions)
  },
  {
    id: FacebookLoginProvider.PROVIDER_ID,
    provider: new FacebookLoginProvider("Facebook-App-Id", fbLoginOptions)
  },
  {
    id: VKLoginProvider.PROVIDER_ID,
    provider: new VKLoginProvider("VK-App-Id", vkLoginOptions)
  },
];

Specifying custom scopes, fields etc. on login

const fbLoginOptions = {
  scope: 'pages_messaging,pages_messaging_subscriptions,email,pages_show_list,manage_pages'
}; // https://developers.facebook.com/docs/reference/javascript/FB.login/v2.11

this.authService.signIn(FacebookLoginProvider.PROVIDER_ID, fbLoginOptions);
