How do I use express-session in my Node.js application?

To use express-session, first install it via npm: npm install express-session. Then, require it in your app.

What are the main options I can configure for express-session?

You can configure options like secret, resave, saveUninitialized, and cookie settings.

Can you show me a basic example of setting it up?

Sure! Here's a simple setup:

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

const app = express();

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

app.get('/', (req, res) => {
  req.session.views = (req.session.views || 0) + 1;
  res.send(`Number of views: ${req.session.views}`);
});

app.listen(3000);

What does the secure option do in the cookie settings?

The secure option ensures that cookies are only sent over HTTPS connections, enhancing security.
