React New Hooks 2023

The useInsertionEffect hook is designed for managing CSS and style insertions. It runs synchronously before all DOM mutations, making it useful for situations where you need to make changes that affect layout before the browser paints the DOM.

useInsertionEffect(() => {
    // Your style or CSS insertion logic here
}, []);

The useEvent hook is designed to handle events in a way that ensures optimal performance and consistency. It provides a stable reference for event handlers, avoiding issues related to closures in React components.

const handleClick = useEvent(() => {
    // Your event handling logic here
});

The useSyncExternalStore hook is used to subscribe to an external store, allowing you to integrate with external state management libraries more easily. It helps manage subscriptions and ensures that the store updates are synchronized with React's rendering process.

const state = useSyncExternalStore(
    subscribe, 
    getSnapshot, 
    getServerSnapshot
);

The useId hook generates unique IDs that are stable across server and client renders. It is particularly useful for accessibility purposes, such as associating labels with form elements.

const id = useId();
// Use the id in your component
<label htmlFor={id}>Name</label>
<input id={id} type="text" />
