React Google Login

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

:warning: 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.

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:

• In the responseGoogle(response) {...} callback function, you should get back a standard JWT located at response.tokenId or res.getAuthResponse().id_token
• Send this token to your server (preferably as an Authorization header)
• 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
• 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>
