native-data-fetching

API authentication and secure token storage in Expo apps are handled using the fetch API combined with expo-secure-store. This pattern ensures tokens are safely persisted and automatically retrieved for authorized network requests.

Offline data fetching and caching with React Query are managed using NetInfo integration and the React Query online manager. This setup handles staleTime, persistence, and query invalidation across network changes for reliable offline sync.

API endpoints in Expo are configured using build-time EXPO_PUBLIC_ environment variables. This approach provides configurable environment URLs for client applications to point to different API endpoints securely.

Retry logic with exponential backoff for fetch requests is supported through typed error handling and abortable requests. This ensures robust network requests automatically recover from transient failures.

Yes, stateful caching and synchronization work with SWR or React Query. Both libraries manage staleTime, retries, and invalidation to synchronize remote data effectively across network changes.

Abortable requests and typed API error handling are implemented by wrapping the fetch API with configurable logic. This ensures network requests can be safely cancelled and API errors are structurally typed for debugging.
