Description: Google OAuth2 using Google Identity Services for React 🚀
Latest version: 0.12.2

# React OAuth2 | Google

Google OAuth2 using the new [**Google Identity Services SDK**](https://developers.google.com/identity/gsi/web) for React [@react-oauth/google](https://www.npmjs.com/package/@react-oauth/google)🚀

## Install

```sh
$ npm install @react-oauth/google@latest

# or

$ yarn add @react-oauth/google@latest
```

## Demo

https://react-oauth.vercel.app/

## Seamless sign-in and sign-up flows

### Sign In With Google

Add a personalized and customizable sign-up or sign-in button to your website.

### One-tap sign-up

Sign up new users with just one tap, without interrupting them with a sign-up screen. Users get a secure, token-based, passwordless account on your site, protected by their Google Account.

### Automatic sign-in

Sign users in automatically when they return to your site on any device or browser, even after their session expires.

## User authorization for Google APIs (with custom button)

OAuth 2.0 implicit and authorization code flows for web apps

> The Google Identity Services JavaScript library helps you to quickly and safely obtain access tokens necessary to call Google APIs. Your web application, complete either the OAuth 2.0 implicit flow, or to initiate the authorization code flow which then finishes on your backend platform.

## How to use

1. Get your [**Google API client ID**](https://console.cloud.google.com/apis/dashboard)

> Key Point: Add both `http://localhost` and `http://localhost:<port_number>` to the Authorized JavaScript origins box for local tests or development.

2. Configure your OAuth [**Consent Screen**](https://console.cloud.google.com/apis/credentials/consent)

3. Wrap your application with `GoogleOAuthProvider`

```jsx
import { GoogleOAuthProvider } from '@react-oauth/google';

<GoogleOAuthProvider clientId="<your_client_id>">...</GoogleOAuthProvider>;
```

### Sign In With Google

```jsx
import { GoogleLogin } from '@react-oauth/google';

<GoogleLogin
  onSuccess={credentialResponse => {
    console.log(credentialResponse);
  }}
  onError={() => {
    console.log('Login Failed');
  }}
/>;
```

### One-tap

```jsx
import { useGoogleOneTapLogin } from '@react-oauth/google';

useGoogleOneTapLogin({
  onSuccess: credentialResponse => {
    console.log(credentialResponse);
  },
  onError: () => {
    console.log('Login Failed');
  },
});
```

or

```jsx
import { GoogleLogin } from '@react-oauth/google';

<GoogleLogin
  onSuccess={credentialResponse => {
    console.log(credentialResponse);
  }}
  onError={() => {
    console.log('Login Failed');
  }}
  useOneTap
/>;
```

> If you are using one tap login, when logging user out consider [this issue](https://developers.google.com/identity/gsi/web/guides/automatic-sign-in-sign-out#sign-out) may happen, to prevent it call `googleLogout` when logging user out from your application.

```jsx
import { googleLogout } from '@react-oauth/google';

googleLogout();
```

### Automatic sign-in

> `auto_select` prop `true`

```jsx

<GoogleLogin
    ...
    auto_select
/>

useGoogleOneTapLogin({
    ...
    auto_select
});
```

### Custom login button (implicit, authorization code & credential flow)

#### Implicit flow

```jsx
import { useGoogleLogin } from '@react-oauth/google';

const login = useGoogleLogin({
  onSuccess: tokenResponse => console.log(tokenResponse),
});

<MyCustomButton onClick={() => login()}>
  Sign in with Google 🚀{' '}
</MyCustomButton>;
```

#### Authorization code flow

> Requires backend to exchange code with access and refresh token.

```jsx
import { useGoogleLogin } from '@react-oauth/google';

const login = useGoogleLogin({
  onSuccess: codeResponse => console.log(codeResponse),
  flow: 'auth-code',
});

<MyCustomButton onClick={() => login()}>
  Sign in with Google 🚀{' '}
</MyCustomButton>;
```

#### Credential flow

This will return a JWT token in `tokenResponse.credential`.

```jsx
import { useGoogleLogin } from '@react-oauth/google';

const login = useGoogleLogin({
  onSuccess: credentialsResponse => console.log(tokenResponse),
  flow: 'credential',
});

<MyCustomButton onClick={() => login()}>
  Sign in with Google 🚀{' '}
</MyCustomButton>;
```

#### Checks if the user granted all the specified scope or scopes

```jsx
import { hasGrantedAllScopesGoogle } from '@react-oauth/google';

const hasAccess = hasGrantedAllScopesGoogle(
  tokenResponse,
  'google-scope-1',
  'google-scope-2',
);
```

#### Checks if the user granted any of the specified scope or scopes

```jsx
import { hasGrantedAnyScopeGoogle } from '@react-oauth/google';

const hasAccess = hasGrantedAnyScopeGoogle(
  tokenResponse,
  'google-scope-1',
  'google-scope-2',
);
```
