2. From a CommonJS file, use a dynamic import inside an async function: const eslintPluginReactRefresh = await import("eslint-plugin-react-refresh"). That works on every Node.js version the package supports.
3. If you need a synchronous require() or run Node.js 18: npm install eslint-plugin-react-refresh@0.4.26, the last CommonJS release (published Dec 16, 2025).
4. TypeScript: types are bundled; install nothing extra.
