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}`));
