To use React 19 hooks like useTransition for non-urgent updates, you can invoke modern React patterns to mark state updates as transitions. This keeps the UI responsive during heavy rendering tasks by prioritizing urgent user interactions over background data fetching.

useDeferredValue is used in modern React applications to defer re-rendering of less urgent parts of the screen. It allows you to optimize performance by keeping the main thread unblocked while slower components catch up with new data without blocking input.

Yes, you can use modern React patterns with your existing Next.js project. The skill is tailored for React 19+ applications and provides optimizations that work seamlessly within both frontend and server-side Next.js environments.

The best way to implement optimistic UI updates in React 19 is by using the useOptimistic hook. It allows you to immediately show the expected result of an action before the server response arrives, enhancing perceived performance and user experience.

You need to use useTransition instead of useDeferredValue when you want to mark a specific event handler's state update as non-urgent. useDeferredValue is used when you need to defer a value received from a parent component that causes expensive re-renders.
