Nearly every app requires an authorization system on top of an authentication system. We often need a fine-grained permissions model to allow only specific users to access certain resources while simultaneously restricting access for everyone else.

Called a role-based authentication, we’ll learn how to implement this system in an API using Node.js and Firebase.
