How Offline Mode Works: WatermelonDB Architecture
Traditional vs Offline-First architecture
Traditional Apps
CLIENT-SERVER ARCHITECTURE
Mobile App → Internet → Cloud → Internet → Mobile App
Problems:
No internet = app doesn't work
Every action requires server roundtrip (200-500ms)
Failed requests = lost data
Slow on 2G/3G networks (3-10 seconds per action)
