expressjsHow do I use cookies with Express.js?

Cookies are small pieces of data stored in the browser of a user that can be used to identify the user and enable user-specific functionality in the application. Express.js provides a middleware to handle cookie-based authentication.

To use cookies with Express.js, first install the cookie-parser middleware:

npm install cookie-parser

Then, add the cookie-parser middleware to your Express.js application:

const express = require('express');
const cookieParser = require('cookie-parser');

const app = express();
app.use(cookieParser());

Now, you can set and get cookies from the request and response objects:

// Set cookie
res.cookie('name', 'value', { maxAge: 3600 });

// Get cookie
const name = req.cookies.name;

The code above sets a cookie with the name name and the value value that will expire after one hour. You can also use the cookie-parser middleware to sign and verify cookies.
