Observer Patterns

Hello!

I’m making my first app on this platform and would like to include some observer patterns. The more difficult one involves a new user sign up. I’m using your user library and your login function and I’d like to be able to trigger some functions when a new person signs up. In other programs I’d use an observer pattern to watch for events but since I don’t have access to the login functions inner workings I’m not sure how to do that here. Can anyone help? Thanks!
