native-data-fetching

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 calls are slow" -> Check caching strategy, use React Query staleTime User: "How do I configure different API URLs...
