native-data-fetching

Network requests, API calls, and data fetching for Expo apps with caching, error handling, and offline support. You MUST use this skill for ANY networking work including API requests, data fetching, caching, or network debugging. Consult these resources as needed: Use this skill when: Simple GET request : POST request with body : Setup : Fetching data : Mutations : Comprehensive error handling : Retry logic : Token management : Token refresh : Check network status : Offline-first with React Query : Using environment variables for API configuration : Expo supports environment variables with the EXPO_PUBLIC_ prefix. These are inlined at build time and available in your JavaScript code. Environment-specific configuration : Creating an API client with environment config : Important notes : TypeScript support : Cancel on unmount : With React Query (automatic): Wrong: No error handling Right: Check response status Wrong: Storing tokens in AsyncStorage Right: Use SecureStore for sensitive data User: "How do I make API calls in React Native?" -> Use fetch, wrap with error handling User: "Should I use React Query or SWR?" -> React Query for complex apps, SWR for simpler needs User: "My app needs to work offline" -> Use NetInfo for status, React Query persistence for caching User: "How do I handle authentication tokens?" -> Store in expo-secure-store, implement refresh flow User: "API...
