Research direction

Start by reading src/index.js at line 9, where the legacy ReactDOM root API is used. Replace that deprecated entry point with the React 18+ client root API described in the issue, then verify the application still mounts and the React Review warning is gone.

1. [warning] no-react-dom-deprecated-apis — src/index.js:9
   ReactDOM.render is the legacy root API — switch to `import { createRoot } from 'react-dom/client'` and call `createRoot(container).render(...)` (REMOVED in React 19)
⚠️ Warnings (1)

no-react-dom-deprecated-apis

ReactDOM.render is the legacy root API — switch to import { createRoot } from 'react-dom/client' and call createRoot(container).render(...) (REMOVED in React 19)

Switch the legacy react-dom root API (render / hydrate / unmountComponentAtNode) to createRoot / hydrateRoot / root.unmount() from react-dom/client. Replace findDOMNode with a ref. The whole react-dom/test-utils entry point is removed in React 19 — use act from react and fireEvent / render from @testing-library/react. Only enabled on projects detected as React 18+.
