How do I implement Passport.js in my Express application?

To implement Passport.js in your Express app, first install it using npm. You can do this by running npm install passport passport-local express-session.

What are the steps after installing it?

After installation, you need to set up session management, initialize Passport, and define your authentication strategy.

Can you give me a code example for setting up the local strategy?

Sure! Here's a basic example:

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

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

How do I handle user sessions?

You can handle user sessions by using express-session. Set it up like this:

app.use(session({ secret: 'your_secret', resave: false, saveUninitialized: true }));
app.use(passport.initialize());
app.use(passport.session());
