How can I implement advanced usage of Passport.js with OAuth2?

To implement advanced usage of Passport.js with OAuth2, you can start by configuring multiple OAuth2 providers. This allows your application to authenticate users from different platforms like Google, Facebook, or GitHub.

Can you give me an example of configuring multiple providers?

Sure! You can set up multiple strategies in your Passport configuration like this:

passport.use(new GoogleStrategy({
  clientID: GOOGLE_CLIENT_ID,
  clientSecret: GOOGLE_CLIENT_SECRET,
  callbackURL: '/auth/google/callback'
}, function(accessToken, refreshToken, profile, done) {
  // User authentication logic
}));

passport.use(new FacebookStrategy({
  clientID: FACEBOOK_APP_ID,
  clientSecret: FACEBOOK_APP_SECRET,
  callbackURL: '/auth/facebook/callback'
}, function(accessToken, refreshToken, profile, done) {
  // User authentication logic
}));

What about handling user sessions?

You can manage user sessions by using express-session along with Passport. After successful authentication, you can serialize the user and store their information in the session.
