Contributions

PRs are welcome and much appreciated that keeps this plugin up to date with Capacitor and official Google Auth platform library feature parity.

Try to follow good code practices. You can even help keeping the included demo updated.

PRs for features that are not aligned with the official Google Auth library are discouraged.

(We are beginner-friendly here)

npm i --save @codetrix-studio/capacitor-google-auth

# pnpm 
pnpm add @codetrix-studio/capacitor-google-auth

# yarn 
yarn add @codetrix-studio/capacitor-google-auth

Updating

If need migrate to different Capacitor versions see instruction for migrate plugin to new version.

Usage

WEB

Register plugin and manually initialize

import { GoogleAuth } from '@codetrix-studio/capacitor-google-auth';

// use hook after platform dom ready
GoogleAuth.initialize({
  clientId: 'CLIENT_ID.apps.googleusercontent.com',
  scopes: ['profile', 'email'],
  grantOfflineAccess: true,
});

or if need use meta tags (Optional):

<meta name="google-signin-client_id" content="{your client id here}" />
<meta name="google-signin-scope" content="profile email" />

Options

  • clientId - The app's client ID, found and created in the Google Developers Console.
  • scopes – same as Configure scopes
  • grantOfflineAccess – boolean, default false, Set if your application needs to refresh access tokens when the user is not present at the browser.

Use it

GoogleAuth.signIn();

Angular

init hook

// app.component.ts
constructor() {
  this.initializeApp();
}

initializeApp() {
  this.platform.ready().then(() => {
    GoogleAuth.initialize()
  })
}

sign in function

async googleSignIn() {
  let googleUser = await GoogleAuth.signIn();

  /*
    If you use Firebase you can forward and use the logged in Google user like this:
  */
  const credential = auth.GoogleAuthProvider.credential(googleUser.authentication.idToken);
  return this.afAuth.auth.signInAndRetrieveDataWithCredential(credential);
}

Vue 3

<script setup lang="ts">
import { defineComponent, onMounted } from 'vue';
import { GoogleAuth } from '@codetrix-studio/capacitor-google-auth';

onMounted(() => {
  GoogleAuth.initialize();
});

async function logIn() {
  const response = await GoogleAuth.signIn();
  console.log(response);
}
</script>

or see more CapacitorGoogleAuth-Vue3-example

iOS

  1. Create in Google cloud console credential Client ID for iOS and get Client ID and iOS URL scheme

  2. Add identifier REVERSED_CLIENT_ID as URL schemes to Info.plist from iOS URL scheme
    (Xcode: App - Targets/App - Info - URL Types, click plus icon)

  3. Set Client ID one of the ways:

    1. Set in capacitor.config.json
      • iosClientId - specific key for iOS
      • clientId - or common key for Android and iOS
    2. Download GoogleService-Info.plist file with CLIENT_ID and copy to ios/App/App necessarily through Xcode for indexing.

plugin first use iosClientId if not found use clientId if not found use value CLIENT_ID from file GoogleService-Info.plist

Android

Set Client ID :

  1. In capacitor.config.json

    • androidClientId - specific key for Android
    • clientId - or common key for Android and iOS
  2. or set inside your strings.xml

plugin first use androidClientId if not found use clientId if not found use value server_client_id from file strings.xml

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

Refresh method

This method should be called when the app is initialized to establish if the user is currently logged in. If true, the method will return an accessToken, idToken and an empty refreshToken.

checkLoggedIn() {
    GoogleAuth.refresh()
        .then((data) => {
            if (data.accessToken) {
                this.currentTokens = data;
            }
        })
        .catch((error) => {
            if (error.type === 'userLoggedOut') {
                this.signin()
            }
        });
}
