Make an example with tests

Feature request:

It would be great to make a canonical example with automated testing to ensure the API is covered and working as expected.

I have a starting app here. I'll update this issue with more details when I push the example app for automating testing.

The example app (currently just app structure) is a WIP at: https://github.com/fullstackio/FirestackApp
