Capacitor Google Auth plugin

Install

npm i capacitor-google-auth

npx cap update

iOS

Make sure you have GoogleService-Info.plist with CLIENT_ID

Add REVERSED_CLIENT_ID as url scheme to Info.plist

Android

Inside your strings.xml

<resources>
  <string name="server_client_id">Your Web Client Key</string>
</resources>

Import package inside your MainActivity

import com.rediska1114.plugins.GoogleAuth;

Register plugin inside your MainActivity.onCreate

this.init(savedInstanceState, new ArrayList<Class<? extends Plugin>>() {{
  add(GoogleAuth.class);
}});

Configure

Provide configuration in root capacitor.config.json

{
  "plugins": {
    "GoogleAuth": {
      "scopes": ["profile", "email"],
      "serverClientId": "xxxxxx-xxxxxxxxxxxxxxxxxx.apps.googleusercontent.com",
      "forceCodeForRefreshToken": true
    }
  }
}

Note : forceCodeForRefreshToken force user to select email address to regenerate AuthCode used to get a valid refreshtoken (work on iOS and Android) (This is used for offline access and serverside handling)

Available methods:

• signIn()
• refresh() (iOS only)
• signOut()

Usage example:

1. In your module (e.g. app.module.ts)

...
import { GoogleAuth } from 'capacitor-google-auth'

@NgModule({
	...
	providers: [
		...
		GoogleAuth,
	],
})
export class AppModule {}

2. In your component or service (e.g. auth.service.ts)

...
import { GoogleAuth } from 'capacitor-google-auth'

@Injectable()
export class AuthService {
	constructor(private googleAuth: GoogleAuth, private api: ApiService) {}

    async googleSignIn() {
		const googleUser = await this.googleAuth.signIn();
		const { token } = await this.api.signInWithGoogle(googleUser)
	}
}
