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;

1. 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;
   

   
   

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

   
   
   

   Right now, you will see that the cookies you have isn't show on the response.
   
   
   
4. 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}`));
