Testing Google reCAPTCHA Integration And Google-Oauth2 with Frontend and Backend & Implementing useForm Hook

To ensure the effectiveness of Google reCAPTCHA and improve your form handling practices, follow these steps:

1. Testing Google reCAPTCHA Integration:

Frontend:

• Integrate the Google reCAPTCHA widget into your frontend application.
• Verify that the reCAPTCHA challenge appears correctly on your forms.
• Ensure that users can complete the reCAPTCHA challenge and that the token is included in form submissions.

Backend:

• Check that your backend correctly receives the reCAPTCHA token from the frontend.
• Confirm that the backend makes a request to Google’s reCAPTCHA verification API using the correct secret key and token.
• Ensure the backend properly handles the verification response and returns appropriate success or error messages based on the result.

2. Implementing useForm Hook for Practice:

Setup:

• Create a custom useForm hook to manage form state and handle form submissions.
• Use the hook to simplify form handling by managing input values, validation, and submission logic in a reusable manner.

Implementation:

• Initialize form state and validation rules within the hook.
• Provide functions to handle input changes, form submission, and validation.
• Ensure the hook integrates well with your frontend components and provides a smooth user experience.

Testing:

• Test the useForm hook to ensure it correctly manages form state and handles form submissions.
• Validate that the hook integrates seamlessly with the reCAPTCHA functionality and other form elements.

3. Google OAuth2 Integration

• This Node.js application features Google OAuth2 authentication, enabling secure user login via Google accounts.
• The integration uses Google's OAuth2.0 credentials to authenticate users.
• Upon successful login, an index.html page is generated dynamically, displaying user-specific information retrieved from Google's services.
• This implementation ensures a seamless and secure authentication process for users, leveraging Google's robust authentication infrastructure.

By following these steps, you will ensure both a robust Google reCAPTCHA integration, Google-Oauth2 and effective form handling using a custom useForm hook. This approach will enhance your form security and user experience while practicing advanced form management techniques.

reCAPTCHA

Client side:

import ReCAPTCHA from 'react-google-recaptcha';

function onChange(value: any) { console.log(value); }

<ReCAPTCHA style={{display: 'inline-block'}} sitekey={secrete_site_key} onChange={onChange} ref={recaptchaRef} /> Server side:

const { valueReCapcha } = req.body;

const response = await axios.post(https://www.google.com/recaptcha/api/siteverify?secret=${process.env.BackEndSecret}&response=${valueReCapcha});

const data = response.data;

Google Oauth2

Cient side: login with Login

Server side: 1: auth.js file

2: import express from 'express';

import 'dotenv/config';

import session from 'express-session';

import passport from 'passport';

import { fileURLToPath } from 'url';

import path from 'path';

import './controllers/auth.js';

const app = express();

const PORT = process.env.PORT || 4001;

const __filename = fileURLToPath(import.meta.url);

const __dirname = path.dirname(__filename);app.use( session({ secret: process.env.SESSION_SECRET || 'mysecret', resave: false, saveUninitialized: true, cookie: { secure: false }, }) );

app.use(passport.initialize()); app.use(passport.session());

// Static files app.use(express.static(path.join(__dirname, './index.html')));

// Authentication check middleware function isLoggedIn(req, res, next) { req.user ? next() : res.sendStatus(401); }

// Routes app.get('/', (req, res) => { res.sendFile(path.join(__dirname, 'index.html')); });

app.get('/auth/google', passport.authenticate('google', { scope: ['email', 'profile'] }) );

app.get('/auth/google/callback', passport.authenticate('google', { successRedirect: '/auth/google/success', failureRedirect: '/auth/google/failure', }) );

app.get('/auth/google/failure', (req, res) => { res.send('Something went wrong!'); });

app.get('/auth/protected', isLoggedIn, (req, res) => { let name = req.user.displayName; res.send(Hello ${name}); });

app.use('/auth/logout', (req, res) => { req.session.destroy(); res.send('See you again!'); });

app.use('/auth/google/success', (req, res) => { res.send('Login successfully!'); });
