Article Summary
Building offline-first React Native apps? The network will fail. Your app doesn't have to.
Callstack's guide tackles the reality that mobile apps lose connectivity constantly. This 2017 piece remains relevant as it walks through practical strategies for handling offline states, caching data, and syncing when connections return in React Native applications.
Key Takeaways
- Detect network state changes using NetInfo for real-time connectivity awareness
- Implement Redux middleware to queue actions when offline and replay on reconnect
- Use AsyncStorage for persistent local data that survives app restarts
- Handle optimistic UI updates so users never wait for network responses
Critical Insight
Offline-first architecture turns network failures from app-breaking bugs into seamless user experiences through strategic caching and action queuing.
