Research direction

Open src/index.tsx at line 8 and inspect the existing ReactDOM root call. Replace the legacy root API with the React client root API described in the issue. Done means the application entry point no longer uses ReactDOM.render and still renders the app through the new root API.

⚠️ 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+.
