Using Cookies

How to use cookies

Now as we can send cookies, I'll show you an example of how to get that cookies from user and use it.

const ShowCookies = (req, res) => {
	const cookies = req.cookies;
	res.send(cookies);
};

module.exports = ShowCookies;

First let's create new file at /controllers/cookies name showCookies.js

const ShowCookies = (req, res) => {
	const cookies = req.cookies;
	res.send(cookies);
};

module.exports = ShowCookies;

Also add the routes as /cookies/show in your cookiesRouter file. Now try get the locahlost:4000/cookies/show

Right now, you will see that the cookies you have isn't show on the response.


Install the cookie-parser by npm i cookie-parser and use it in the index.js as show:

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

const app = express();
const port = 4000;

app.use(cookieParser());

app.get('/', (req, res) => res.send('Hello World!'));

app.use('/cookies', require('./routes/cookies'));

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