More Functions, Emulators and Express!

Since I made this video back in 2016, Firebase has come a very long way. One of the really neat things they added was the ability to tie an Express application (Node web framework) into your functions and tell Firebase hosting that's where your site lives! This is a "best of both worlds" scenario and amounts to having a virtually free Express app powered by Functions.

Google also released a suite of emulators to help when building out Functions, making testing a bit nicer. Finally, they also have the notion of "callable" functions which can be invoked from the client SDK rather than an HTTP request. Fascinating stuff!
