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`).
How to use it
- Start your plan and connect your AI once
- Ask for the task in your own words, or say it directly:
Use the Native data fetching skill to help me with this.Without a connection: copy the SKILL.md below into your AI's project instructions.
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](references/detailed-guide.md) 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.
- Do not treat generated examples as a substitute for environment-specific tests, security review, or user approval for destructive or costly actions.
