How are sensitive authentication tokens handled?

It implements secure storage patterns using expo-secure-store rather than AsyncStorage to ensure sensitive data like JWTs are encrypted on the device.

Does it support offline functionality?

Yes, the skill provides implementation patterns for NetInfo to detect connectivity and React Query logic to pause and resume requests based on network status.

Does this skill recommend Axios or Fetch for Expo?

This skill prioritizes the native fetch API (expo/fetch) over Axios to minimize bundle size and ensure better compatibility with the Expo ecosystem.

How do I manage different API URLs for dev and production?

The skill guides you in using EXPO_PUBLIC_ environment variables and .env files to switch between local, staging, and production endpoints at build time.

Mobile Development

Optimizes network requests and data synchronization for Expo and React Native applications using best practices for fetch and React Query.

This skill provides a comprehensive framework for managing networking and data persistence within Expo environments. It guides developers through implementing robust API clients using the native fetch API, setting up advanced server-state management with TanStack Query, and securing sensitive authentication tokens with SecureStore. By emphasizing standardized error handling, exponential backoff retries, and offline-first patterns using NetInfo, it ensures mobile applications remain reliable and performant across diverse network conditions.
