Supabase migration

[lebaaar]

Migrate backend to Supabase;

• Migrate DB to PostgreSQL
  • Design new schema
  • Implement RLS in supabase
• Migrate authentication
• Migrate Firebase cloud functions to Supabase edge functions

---

Migrating because:

• Firebase bills per Db read, which we have almost hit daily limits just when developing locally. Supabase has no read limits (only a smaller DB capacity, fair tradeoff)
• Easier migration to custom backend

We will eventually migrate to custom backend, so keep in mind when migrating. Try not to vendor lock in to Supabase
