Anyways, this was the last piece of the Firebase puzzle for me. Between this, Authentication, Analytics, the DB (obviously) and Storage, Firebase has been indispensable in getting my side project app up and running -- and most importantly, feeling "real."
My only request at this point would be a bit more TLC given to how Firebase integrates with React Native. I'm sure it's coming as it's likely a "still-small-but-growing" subset of use cases. As an example, there's not an obvious way to say, get Twitter auth working in a React Native app (last I checked a few weeks ago.) There are workarounds, of course.
PS- The Firebase console and docs are some of the most slick and well-designed examples of what they do I've seen. I really enjoy the web console and the CLI tool. Just a real joy to use, and I'm not being sarcastic. :)
