How can I manage sessions in an Express application?

You can manage sessions in an Express application using the express-session middleware. Would you like a code example?

Yes, please provide a code example.

Here's a simple example:

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, () => {
  console.log('Server is running on port 3000');
});

This sets up a basic session management system.

What are the security considerations I should keep in mind?

You should ensure that your session secret is strong, use HTTPS to protect cookies, and consider setting cookie options like httpOnly and secure.
