Offlining mobile apps require robust local storage, reliable data synchronization, and effective conflict resolution to stay productive even when the network is unavailable.
Initialize storage with MMKV, implement an optimistic update, and configure a minimal background sync loop.

Offline-first architecture stores data locally using AsyncStorage, MMKV, SQLite, or WatermelonDB, then syncs with the server when connectivity returns. This keeps your app functional even without network access and enables fast load times by reading from local storage first.
Implement background synchronization with optimistic updates: write changes to local storage immediately, mark them with a _synced flag, queue failed requests for retry, and sync when the network is available. This provides instant feedback while ensuring eventual consistency with the server.
Offline-first sync strategies include last-write-wins, where the most recent change takes precedence, or manual resolution, where you define custom logic. The approach you choose depends on whether data conflicts are acceptable or require user intervention.
Yes, React Native apps can use offline-first storage and sync. AsyncStorage, MMKV, SQLite, and WatermelonDB all work with React Native to enable local persistence and background synchronization across iOS and Android.
AsyncStorage suits simple key-value data, MMKV offers faster performance for moderate datasets, SQLite provides relational querying for complex data, and WatermelonDB adds reactive queries and built-in sync. Choose based on data structure complexity and query needs.
