React

Example Prompts

• "Build a multi-step form wizard with validation and progress tracking"
• "Create a custom hook for infinite scroll with intersection observer"
• "Refactor class components to modern hooks with proper state management"

Example Output

function useInfiniteScroll<T>(fetchFn: (page: number) => Promise<T[]>) {
  const [items, setItems] = useState<T[]>([]);
  const [page, setPage] = useState(1);
  const observerRef = useRef<IntersectionObserver>();
  const lastItemRef = useCallback((node: HTMLElement | null) => {
    if (observerRef.current) observerRef.current.disconnect();
    observerRef.current = new IntersectionObserver(entries => {
      if (entries[0].isIntersecting) setPage(p => p + 1);
    });
    if (node) observerRef.current.observe(node);
  }, []);
  return { items, lastItemRef };
}
