How does it handle authentication tokens?

It provides implementation details for using expo-secure-store to encrypt and store tokens safely, along with logic for handling token expiration and automatic refresh flows.

Can this skill help with offline functionality?

Yes, it provides patterns for using NetInfo to monitor connectivity and configuring React Query persistence to allow apps to function gracefully without an active internet connection.

Does this skill support Axios for network requests?

The skill preferences the native fetch API (expo/fetch) over Axios to reduce bundle size and maintain better compatibility with the Expo ecosystem.

How should I store API keys securely in an Expo app?

The skill recommends using EXPO_PUBLIC_ prefixed environment variables for client-side keys and non-prefixed variables for server-side secrets in API routes, while never exposing sensitive write-access keys in the client bundle.
