How do I use sessions in my application?

To use sessions, you first need to set up a session management system. Are you using a specific framework?

Yes, I'm using Express.js. How do I implement sessions there?

In Express.js, you can use the 'express-session' middleware. First, install it using npm, then set it up in your app.

Can you show me a code example?

Sure! Here's a basic example:

const session = require('express-session');

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

This initializes the session middleware.

What about storing user data in the session?

You can store user data in the session like this:

req.session.user = { id: userId, name: userName };

This way, you can access it in subsequent requests.
