React Google Login

A React Google Login Component.


npm install react-google-login

How to use

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

const responseGoogle = (response) => {


Google button without styling or custom buttom

    render={renderProps => (
      <button onClick={renderProps.onClick}>This is my custom Google button</button>

onSuccess callback

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

If responseType is 'code', callback will return the offline token for use on your 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.hg.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
  4. The returned decoded token should have an hd key equal to the hosted domain you'd like to restrict to.


Use GoogleLogout button to logout the user from google.

    import { GoogleLogout } from 'react-google-login';
