Node CSRF Middleware

csrf-protection is a Node.js library that provides middleware functions for generating and validating CSRF tokens in web applications.

Installation

To install the library, use the following npm command:

npm install csrf-protection

Usage

$3

const csrf = require('csrf-protection');

$3

This middleware generates a CSRF token and adds it to the response cookie. The token is also available in the res.locals.csrfToken variable for use in forms.

$3

This middleware checks the CSRF token in the request against the one stored in the cookie. If the tokens match, the request is allowed to proceed; otherwise, a 403 Forbidden response is sent.

Configuration

Example

``javascript
const express = require('express');
const csrf = require('csrf-protection');
const cookieParser = require('cookie-parser');
const app = express();

app.use(express.urlencoded({ extended: true })); // Required
app.use(cookieParser()); // Required

const csrff = csrf({
secret: 'Hello World!' // Your Secret Key
});

app.get('/', csrff.csrfCreate, (req, res) => {
const csrfToken = res.locals.csrfToken;

console.log(csrfToken);

res.send(

Example

User Name:

Send

);
});

app.post('/submit', csrff.csrfCheck, (req, res) => {
res.send(Hello World!);
});

app.listen(3000, () => { console.log('Server is running on port 3000'); });
``
