Firebase fundamentals – Free Udemy Courses

This course will take you through some of Firebase’s main offerings: Authentication, Firestore, and Cloud Functions. There is a good mix of lecture content and walkthrough content; 34 minutes of content is a step-by-step guide on how you would set up a simple chat site with Firebase.

Code is included for the walkthrough and for integrating Twitch, an unofficially supported identity provider, with Firebase Authentication.
