native-data-fetching
Use when implementing or debugging ANY network request, API call, or data fetching. Covers fetch API, React Query, SWR, error handling, caching, offline support, and Expo Router data loaders (`useLoaderData`).
Why this skill is useful
Provides specific patterns and implementations for data fetching and error handling in React and Expo that the AI wouldn't reliably generate on its own.
What it needs
Requires expo installed locally. About 2k tokens when loaded. Last updated 2026-08-07. 44,571 stars on the source repository.
What this skill does
Expo Networking You MUST use this skill for ANY networking work including API requests, data fetching, caching, or network debugging. Detailed Guide Read the detailed guide before executing this skill. It retains the complete procedure and reference material. Treat its safety, prerequisites, and validation requirements as mandatory. For focused work, load the relevant sections; for end-to-end work, read the guide completely. When to Use Use this skill when: Implementing API requests Setting up data fetching (React Query, SWR) Using Expo Router data loaders (useLoaderData, web SDK 55+) Debugging network failures Implementing caching strategies Handling offline scenarios Authentication/token management Configuring API URLs and environment variables Example Invocations 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 for dev and prod?" -> Use EXPOPUBLIC env vars with .env.development and .env.production files User: "Where should I put my API key?" -> Client-safe keys: EXPOPUBLIC in .env. Secret keys: non-prefixed env vars in API routes only User: "How do I load data for a page in Expo Router?" -> See references/expo-router-loaders.md for route-level loaders (web, SDK 55+). For native, use React Query or fetch. Limitations Use this skill only when the task clearly matches its upstream product or API scope. Verify commands, API behavior, pricing, quotas, credentials, and deployment effects against current official documentation before making changes. …
