Why does this skill prefer fetch over axios?

Standard fetch is built into the Expo environment and is highly optimized. Using fetch reduces bundle size and dependency overhead while providing all necessary features when combined with the provided error-handling wrappers.

Where should I store authentication tokens in Expo?

The skill strictly recommends using expo-secure-store for sensitive data like JWTs rather than AsyncStorage, ensuring tokens are encrypted at rest on both iOS and Android.

Does this skill support offline-first applications?

Yes, it includes implementation guides for NetInfo to monitor connectivity and React Query integration to pause and resume requests automatically based on the user's online status.

How does this skill handle sensitive API keys?

It provides patterns for using environment variables, specifically distinguishing between client-side keys (using the EXPO_PUBLIC_ prefix) and server-side secrets that should never be exposed in the mobile bundle.
