CAPACITOR 5
Capacitor plugin for Google Auth.
If you want to contribute, you can do so in the original repo by CodetrixStudio. This fork is intended for custom adjustments.
npm i --save @SangrePrimitiva/capacitor-google-auth
# pnpm
pnpm add @SangrePrimitiva/capacitor-google-auth
# yarn
yarn add @SangrePrimitiva/capacitor-google-auth
npx cap update
If need migrate to different Capacitor versions see instruction for migrate plugin to new version.
Register plugin and manually initialize
import { GoogleAuth } from '@SangrePrimitiva/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" />
clientId
- The app's client ID, found and created in the Google Developers Console.scopes
– same as Configure scopesgrantOfflineAccess
– boolean, defaultfalse
, Set if your application needs to refresh access tokens when the user is not present at the browser.
Use it
GoogleAuth.signIn();
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);
}
<script setup lang="ts">
import { defineComponent, onMounted } from 'vue';
import { GoogleAuth } from '@SangrePrimitiva/capacitor-google-auth';
onMounted(() => {
GoogleAuth.initialize();
});
async function logIn() {
const response = await GoogleAuth.signIn();
console.log(response);
}
</script>

-
Create in Google cloud console credential Client ID for iOS and get Client ID and iOS URL scheme
-
Add identifier
REVERSED_CLIENT_ID
as URL schemes toInfo.plist
from iOS URL scheme
(Xcode: App - Targets/App - Info - URL Types, click plus icon) -
Set Client ID one of the ways:
- Set in
capacitor.config.json
iosClientId
- specific key for iOSclientId
- or common key for Android and iOS
- Download
GoogleService-Info.plist
file withCLIENT_ID
and copy to ios/App/App necessarily through Xcode for indexing.
- Set in
plugin first use iosClientId
if not found use clientId
if not found use value CLIENT_ID
from file GoogleService-Info.plist
Set Client ID :
-
In
capacitor.config.json
androidClientId
- specific key for AndroidclientId
- or common key for Android and iOS
-
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()
}
});
}
