React Google Login

A Google OAuth Sign-in / Log-in Component for React. Forked from anthonyjgrove/react-google-login.

⚠️ Google is discontinuing Google Sign-In JavaScript Platform Library for web. By default, newly created Client IDs are blocked and if you create IDs before July 29th, 2022, you can set plugin_name to use it. Please migrate to Google Identity Services before March 31, 2023.

Note: This package uses Google Sign-In JavaScript Platform Library and has added support for plugin_name.

Storybook

Demo Link

Install

npm install @leecheuk/react-google-login

How to use

import React from 'react';
import ReactDOM from 'react-dom';
import GoogleLogin from '@leecheuk/react-google-login';
// or
import { GoogleLogin } from '@leecheuk/react-google-login';


const responseGoogle = (response) => {
  console.log(response);
}

ReactDOM.render(
  <GoogleLogin
    clientId="658977310896-knrl3gka66fldh83dao2rhgbblmd4un9.apps.googleusercontent.com"
    buttonText="Login"
    onSuccess={responseGoogle}
    onFailure={responseGoogle}
    cookiePolicy={'single_host_origin'}
  />,
  document.getElementById('googleButton')
);

Google button without styling or custom button

ReactDOM.render(
  <GoogleLogin
    clientId="658977310896-knrl3gka66fldh83dao2rhgbblmd4un9.apps.googleusercontent.com"
    render={renderProps => (
      <button onClick={renderProps.onClick} disabled={renderProps.disabled}>This is my custom Google button</button>
    )}
    buttonText="Login"
    onSuccess={responseGoogle}
    onFailure={responseGoogle}
    cookiePolicy={'single_host_origin'}
  />,
  document.getElementById('googleButton')
);

Stay Logged in

isSignedIn={true} attribute will call onSuccess callback on load to keep the user signed in.

<GoogleLogin
  clientId="658977310896-knrl3gka66fldh83dao2rhgbblmd4un9.apps.googleusercontent.com"
  onSuccess={responseGoogle}
  isSignedIn={true}
/>

Login Hook

import { useGoogleLogin } from '@leecheuk/react-google-login'

const { signIn, loaded } = useGoogleLogin({
    onSuccess,
    onAutoLoadFinished,
    clientId,
    cookiePolicy,
    loginHint,
    hostedDomain,
    autoLoad,
    isSignedIn,
    fetchBasicProfile,
    redirectUri,
    discoveryDocs,
    onFailure,
    uxMode,
    scope,
    accessType,
    responseType,
    jsSrc,
    onRequest,
    prompt
  })

Logout Hook

import { useGoogleLogout } from '@leecheuk/react-google-login'

const { signOut, loaded } = useGoogleLogout({
    jsSrc,
    onFailure,
    clientId,
    cookiePolicy,
    loginHint,
    hostedDomain,
    fetchBasicProfile,
    discoveryDocs,
    uxMode,
    redirectUri,
    scope,
    accessType,
    onLogoutSuccess
  })

onSuccess callback

If responseType is not 'code', callback will return the GoogleAuth object.

If responseType is 'code', callback will return the authorization code that can be used to retrieve a refresh token from the server.

If you use the hostedDomain param, make sure to validate the id_token (a JSON web token) returned by Google on your backend server:

  1. In the responseGoogle(response) {...} callback function, you should get back a standard JWT located at response.tokenId or res.getAuthResponse().id_token
  2. Send this token to your server (preferably as an Authorization header)
  3. Have your server decode the id_token by using a common JWT library such as jwt-simple or by sending a GET request to https://www.googleapis.com/oauth2/v3/tokeninfo?id_token=YOUR_TOKEN_HERE
  4. The returned decoded token should have an hd key equal to the hosted domain you'd like to restrict to.

Logout

Use GoogleLogout button to logout the user from google.

    import { GoogleLogout } from '@leecheuk/react-google-login';
    <GoogleLogout
      clientId="658977310896-knrl3gka66fldh83dao2rhgbblmd4un9.apps.googleusercontent.com"
      buttonText="Logout"
      onLogoutSuccess={logout}
    >
    </GoogleLogout>
