How are authentication tokens handled securely?

The skill implements patterns using expo-secure-store, which ensures sensitive tokens are encrypted and stored in the device's secure keychain rather than insecure storage.

Why does this skill prefer the Fetch API over Axios?

It aligns with Expo's native capabilities and reduces bundle size by utilizing the environment's built-in Fetch API rather than adding external dependencies.

How does it handle environment-specific API URLs?

It uses the EXPO_PUBLIC_ prefix for environment variables, allowing for different configurations across development, staging, and production builds.

Does this skill support offline-first development?

Yes, it provides implementation guides for NetInfo and TanStack Query persistence to allow apps to function gracefully without an active internet connection.

Mobile Development

Implements robust API requests, data fetching patterns, and offline-first strategies for Expo and React Native applications.

This skill provides standardized patterns for managing all aspects of networking within the Expo and React Native ecosystem. It streamlines the implementation of the Fetch API, TanStack Query (React Query), and SWR while enforcing best practices like avoiding Axios in favor of native solutions. The skill covers sophisticated networking requirements including secure token management with Expo SecureStore, exponential backoff retry logic, comprehensive error handling, and offline-first synchronization using NetInfo. It also ensures proper environment variable configuration and request cancellation to optimize mobile app performance and security.
