How can I manage cookies in Node.js?

How can I manage cookies in Node.js?

You can manage cookies in Node.js using the 'cookie' package or by setting headers directly in your HTTP responses.

Can you show me an example of setting a cookie?

Sure! Here's a simple example:

const http = require('http');
const cookie = require('cookie');

const server = http.createServer((req, res) => {
    res.setHeader('Set-Cookie', cookie.serialize('myCookie', 'cookieValue', { httpOnly: true }));
    res.end('Cookie has been set!');
});

server.listen(3000);

What about reading cookies from a request?

To read cookies, you can use the 'cookie' package to parse the cookies from the request headers:

const cookies = cookie.parse(req.headers.cookie || '');
console.log(cookies.myCookie); // Outputs the value of 'myCookie'

Are there any security considerations I should be aware of?

Yes, always set the 'httpOnly' and 'secure' flags on cookies to prevent XSS attacks and ensure they are sent over HTTPS.
