How can I implement advanced OAuth in Express.js?

To implement advanced OAuth in Express.js, you can use the 'passport' library along with specific strategies for different providers.

What are the steps to set up Passport.js for OAuth?

First, install Passport and the required strategies. Then, configure your Express app to use Passport middleware and set up routes for authentication.

Can you explain how to handle callbacks after authentication?

Sure! After authentication, the provider will redirect to your callback URL. You need to handle this route to process the user data and establish a session.

What if I want to add support for multiple OAuth providers?

You can do this by configuring multiple strategies in Passport. Each provider will have its own setup, but the overall process remains similar.
