Package Firebase apps for self-hosting by using Supabase as a drop-in replacement for Firebase.

⚠️ Warning: Under Active Development!

This repo is under active development. It is not ready to be used (definitely not in production, and probably not even in testing).

We'd love help, feedback, and contributions. Please use GitHub Discussions to get involved.

Background

At Roboflow we are heavy users of Firebase. But we are working on on-prem deployment for our customers and there is no self-hosted version of Firebase.

This is where Supabase and supashim come in. Supabase is an open-source Firebase alternative that shares many of the features of Firebase and is able to be self-hosted using Docker Compose or Kubernetes.

Supashim is a shim that hooks into the Firebase calls from your app and translates them into the Supabase equivalents. This means you will be able to take an existing Firebase app and simply swap out the firebase global for supashim to package a self-hosted version of your Firebase app (or to migrate to a Supabase backend) without having to change any application code.

Currently In Progress

Firestore

The shim for firestore is in development on the prototype/firestore branch. Currently, it is working to connect to Supabase, read/write data, recommend and create Postgres indexes (via RPC).

Firestore features currently in active development are:

• Support for realtime queries (this is mocked by polling the query for now)
• Translating Firestore Security Rules into Supabase/Postgres Row Level Security.

Roadmap

We plan to work on shimming the following features next (in this order):

• storage Firebase Cloud Storage
• auth Firebase Authentication

Not Currently Planned

We don't need the following Firebase features for our use-case so do not plan to build them ourselves (and there may not be clear Supabase equivalents) but we would love to have them added to the project by an external contributor if possible:

• analytics Firebase Analytics
• app-check Firebase App Check
• database Firebase Realtime Database
• functions Firebase Functions
• messaging Firebase Cloud Messaging
• performance Firebase Performance Monitoring
• remote-config Firebase Remote Config
• Other features not included in the JS API like Firebase Hosting and Firebase ML.

Please start a Discussion to make a proposal if you'd like to work on any of these or see them added.
