React Hooks・Next.js パターン

To prevent infinite re-render loops, apply the useCallback pattern to stabilize your fetchData function before adding it to the useEffect dependency array, ensuring the function reference remains stable across renders.

The best way to implement optimistic UI updates with Next.js Server Actions is using the useOptimistic hook to immediately reflect expected state changes on the client before the server confirms the transaction. This approach enhances perceived performance and user experience.

Suspense works with loading.tsx by wrapping asynchronous components to stream HTML and display fallback UI while data resolves, enabling seamless asynchronous data fetching without blocking the entire page render.

Yes, you can use Zustand for state management in Next.js Client Components by applying selective subscriptions to prevent unnecessary re-renders and efficiently passing server-to-client data into the Zustand store. This integration maintains robust state synchronization.

Your custom useFetch hook might cause performance issues if it lacks proper dependency management or debounce logic. Implementing patterns like useDebounce alongside stable callback references prevents redundant network requests and optimizes rendering performance.
