## Breaking change in V6

In the v6 version, `clientId` in the initialize method is used in priority over other places you could set up. If before you were using this only on the web, unset it on mobile. Or set it conditionally to replicate old behavior.

## 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)

## Install

#### 1. Install package

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

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

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

#### 2. Update capacitor deps

```sh
npx cap update
```

## Updating

If need migrate to different Capacitor versions [see instruction for migrate plugin to new version](#migration-guide).

## Usage

### WEB

```ts
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):

```html
<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](#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

```ts
GoogleAuth.signIn();
```

#### Angular

init hook

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

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

```ts
import { GoogleAuth } from "@codetrix-studio/capacitor-google-auth";
import { Auth, GoogleAuthProvider, signInWithCredential } from '@angular/fire/auth';

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

/*
    If you use Firebase you can forward and use the logged in Google user like this:
  */
  constructor(private auth: Auth){}

const googleUser = await GoogleAuth.signIn();
  const _credential = GoogleAuthProvider.credential(googleUser.authentication.idToken);
  return signInWithCredential(this.auth, _credential);
}
```

#### Vue 3

```vue
<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](https://github.com/reslear/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**<br>
   (Xcode: App - Targets/App - Info - URL Types, click plus icon)

3. Set **Client ID** one of the ways (by order of importance in the plugin):
   1. Set `clientId` in initialize method
   2. Set `iosClientId` in `capacitor.config.json`
   3. Set `clientId` in `capacitor.config.json`
   4. Set `CLIENT_ID` in `GoogleService-Info.plist`

### Android

Set **Client ID** (by order of importance in the plugin):
1. Set `clientId` in initialize method
2. Set `androidClientId` in `capacitor.config.json`
3. Set `clientId` in `capacitor.config.json`
4. Set `server_client_id` in `strings.xml`

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

Changing Play Services Auth version (Optional) :

This plugin uses `com.google.android.gms:play-services-auth:21.2.0` by default, you can override it providing `gmsPlayServicesAuthVersion` at `variables.gradle`

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

      "scopes": ["profile", "email"],
      "serverClientId": "xxxxxx-xxxxxxxxxxxxxxxxxx.apps.googleusercontent.com",

const config: CapacitorConfig = {
  plugins: {
    GoogleAuth: {
      scopes: ['profile', 'email'],
      serverClientId: 'xxxxxx-xxxxxxxxxxxxxxxxxx.apps.googleusercontent.com',
      forceCodeForRefreshToken: true,
    },
  },
