import React, { Component } from 'react';

class GoogleLoginComponent extends Component {

    componentDidMount() {
        this.googleSDK();
        console.log('sfsfd');
    }

    prepareLoginButton = () => {

    console.log(this.refs.googleLoginBtn);

    this.auth2.attachClickHandler(this.refs.googleLoginBtn, {},
        (googleUser) => {

        let profile = googleUser.getBasicProfile();
        console.log('Token || ' + googleUser.getAuthResponse().id_token);
        console.log('ID: ' + profile.getId());
        console.log('Name: ' + profile.getName());
        console.log('Image URL: ' + profile.getImageUrl());
        console.log('Email: ' + profile.getEmail());

        }, (error) => {
            alert(JSON.stringify(error, undefined, 2));
        });

    }

    googleSDK = () => {

        window['googleSDKLoaded'] = () => {
          window['gapi'].load('auth2', () => {
            this.auth2 = window['gapi'].auth2.init({
              client_id: 'YOUR_APP_CLINT_ID',
              cookiepolicy: 'single_host_origin',
              scope: 'profile email'
            });
            this.prepareLoginButton();
          });
        }

        (function(d, s, id){
          var js, fjs = d.getElementsByTagName(s)[0];
          if (d.getElementById(id)) {return;}
          js = d.createElement(s); js.id = id;
          js.src = "https://apis.google.com/js/platform.js?onload=googleSDKLoaded";
          fjs.parentNode.insertBefore(js, fjs);
        }(document, 'script', 'google-jssdk'));

    }

    render() {

        return (
            <div className="row mt-5">

                    <div className="card mt-3">
                        <div className="card-body">

                            <div className="row mt-5 mb-5">
                                <div className="col-md-4 mt-2 m-auto ">
                                    <button className="loginBtn loginBtn--google" ref="googleLoginBtn">

    }
}

export default GoogleLoginComponent;

Step 4 – Import Google Login Component in App.js

In this step, you need to add GoogleLoginComponent.js file in src/App.js file:

import React from 'react';
import '../node_modules/bootstrap/dist/css/bootstrap.min.css';
import './App.css';
import GoogleLoginComponent from './GoogleLoginComponent';
function App() {
  return (
    <div>

        <GoogleLoginComponent />
