How do I implement user login in my Express app?

To implement user login in your Express app, you can use middleware like Passport.js for authentication.

What are the steps to set up Passport.js?

First, install Passport and the necessary strategies. Then, configure it in your Express app and set up routes for login.

Can you show me a code example?

Sure! Here's a basic example:

const passport = require('passport');
const LocalStrategy = require('passport-local').Strategy;

passport.use(new LocalStrategy((username, password, done) => {
  // Verify username and password
}));

What about session management?

You can use express-session to manage user sessions. Just set it up in your Express app and configure Passport to use it.
