How do I use sessions in web development?

Sessions are used to store user data across multiple pages. You can implement them using server-side languages like PHP, Node.js, or Python.

Can you explain how to set up a session in Node.js?

Sure! You can use the 'express-session' middleware. First, install it using npm, then set it up in your Express app like this:

const session = require('express-session');
app.use(session({
  secret: 'your-secret-key',
  resave: false,
  saveUninitialized: true,
  cookie: { secure: true }
}));

What is the difference between sessions and cookies?

Sessions store data on the server, while cookies store data on the client side. Sessions are more secure for sensitive information.

How can I destroy a session when a user logs out?

You can destroy a session by calling req.session.destroy() in your logout route. This will remove the session data from the server.
