React Native

Example Prompts

• "Build a React Native app with tab navigation, auth, and push notifications"
• "Add offline-first data sync with optimistic updates"
• "Create a custom native module for biometric auth"

Example Output

const useOfflineSync = <T>(key: string, fetchFn: () => Promise<T[]>) => {
  const [data, setData] = useState<T[]>([]);
  const netInfo = useNetInfo();
  useEffect(() => {
    AsyncStorage.getItem(key).then(cached => { if (cached) setData(JSON.parse(cached)); });
    if (netInfo.isConnected) {
      fetchFn().then(fresh => { setData(fresh); AsyncStorage.setItem(key, JSON.stringify(fresh)); });
    }
  }, [netInfo.isConnected]);
  return { data, isOffline: !netInfo.isConnected };
};
