Offline-First

Writes go to local database first (fast!)

Background Sync

Syncs to cloud in background

Cross-Device

Access from all devices

Optional

​
Quick Overview

1

Run Migration

Create Supabase tables:
# In Supabase Dashboard SQL Editor
# Run: supabase/migrations/20241016000000_chat_sync.sql
2

Enable Feature Flag

In FeatureFlags.swift:
public static var chatSyncEnabled: Bool {
    #if DEBUG
    return true  // Change from false
    #else
    return true
    #endif
}
3

Uncomment Implementations

Uncomment in Storage package:
  • SupabaseConversationRepository.swift
  • SupabaseMessageRepository.swift

Wire Up in CompositionRoot

Enable hybrid repositories:
self.conversationRepository = HybridConversationRepository(
    local: localRepo,
    remote: remoteRepo
)
