Offline-first or local-first options for React Native run down | TanStack | Page 1

I'd like to know all my options to create a offline/local-first React Native app with Tanstack DB.

The mobile app would have a local persisted database (SQLite?). The user can read/write from that local database. The local database syncs with a remote database when online.

I'm unsure if each of these supports what I'm looking for.

QueryCollection + persistQueryClient ❓
- No mutation queuing
- Manual conflict resolution
- Manual server data change notification
ElectricCollection ❓
- No local persited store
RxDBCollection ✅
PowerSyncCollection ✅

Do I have the right understanding?

As far as I know ElectricCollection does not persist to the local device - only in-memory

Good to know! Looks amazingly comprehensive.

Would this have a sync engine built in for Postgres?
