Does this skill support SWR?

Yes, while React Query is the primary recommendation, the skill also provides guidance and patterns for using SWR in Expo environments.

Why shouldn't I use fetch in useEffect?

Bare fetch in useEffect lacks caching, automatic retries, and deduplication, often leading to race conditions and inconsistent UI states in mobile apps.

How does it handle offline data?

It provides strategies for cache persistence using libraries like MMKV or AsyncStorage to ensure a seamless offline-first user experience.

Can it fix my code automatically?

Yes, the skill includes automated validation checks that guide Claude to replace legacy fetch patterns with modern hooks like useQuery or useSWR.

Mobile Development

Optimizes data fetching in Expo and React Native applications using React Query and SWR to ensure robust remote state management.

The expo-data-fetching skill streamlines remote state management in React Native and Expo environments by enforcing best practices beyond raw fetch calls. It guides developers in implementing React Query or SWR, setting up persistent cache for offline-first capabilities, and standardizing query keys to prevent bugs. By automating validation checks—such as ensuring data isn't fetched within bare useEffect hooks and verifying that loading and error states are handled—this skill ensures mobile applications remain performant, type-safe, and resilient to network fluctuations.
