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

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

What are the steps to set it up for local authentication?

You'll need to configure Passport with a local strategy, set up session management, and create routes for login and logout.

Can you show me a code example for 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
  }
));

How do I handle user sessions with Passport?

You can use express-session to manage user sessions. Initialize it and use passport.session() middleware.
