React Hooks and Features Overview

useTransition

- Description: useTransition allows you to defer updates to the UI while keeping the interface responsive.
- Usage: It takes two parameters, isPending and startTransition. You wrap the asynchronous function in startTransition
- to handle state updates.
- Usage:


1const [isPending, startTransition] = useTransition();
2
3startTransition(() => {
4  // Your async function here
5});

useActionState

- Description: This hook is used when a component state is updated by an existing action and provides a new action. It takes three arguments: error, submitAction, isPending.
- Usage:


1const [error, submitAction, isPending] = useActionState(
2  async (previousState, formData) => {
3    // Your async function here
4  }
5);

useFormStatus

- Description: A react-dom hook that shows the status of a form, useful for handling form submissions and their states.
- Usage:


1const { pending } = useFormStatus();

useOptimistic

- Description: When making an asynchronous request, useOptimistic shows the final state optimistically while data is being updated.
- Usage:


1const [optimisticName, setOptimisticName] = useOptimistic(currentName);

API use

- Description: This hook is used to read context resources and promises, enabling the passing of data from the server to the client.
- Usage:


1const theme = use(ThemeContext);

ref={ref}

- Description: Instead of using forwardRef, you can directly use ref as a prop for functional components.
- Usage:


1function MyInput({placeholder, ref}) {
2  return <input placeholder={placeholder} ref={ref} />
3}
4
5//...
6<MyInput ref={ref} />

<Context>

- Description: Instead of using context.provider, you can directly use context to simplify context usage.
- Usage:


1const ThemeContext = createContext('');
