Firebase Firestore Database beta

As you possibly know, yesterday Google released their new fully-managed NoSQL document database for mobile and web app development aka Firestore Database. It include a lot of new features regarding the data storage in the cloud. I just wrap all the new methods in a pre-release for you all.

This way you will be able to experiment with Firestore without needing of mixing normal Firebase API and Rx2Firebase. This pre-release is also a Beta, so please, any error, suggestion or change that you see viable, don't doubt in launch a PR to the firestore-beta branch. The tests will be added in the future, but if you want to add a bit of security and mockito work, feel free to do it 👍

If you don't know nothing about Firestore yet, read the next posts to learn about it:
