React DOM APIs

These APIs can be imported from your components. They are rarely used:

• createPortal lets you render child components in a different part of the DOM tree.
• flushSync lets you force React to flush a state update and update the DOM synchronously.

---

React DOM entry points

The react-dom package provides two additional entry points:

• react-dom/client contains APIs to render React components on the client (in the browser).
• react-dom/server contains APIs to render React components on the server.

Deprecated React DOM APIs

• findDOMNode finds the closest DOM node corresponding to a class component instance.
• hydrate mounts a tree into the DOM created from server HTML. Deprecated in favor of hydrateRoot.
• render mounts a tree into the DOM. Deprecated in favor of createRoot.
• unmountComponentAtNode unmounts a tree from the DOM. Deprecated in favor of root.unmount().
