Feel free to use it to test new features and functionalities.\n\n\u003e **Note:** This repository is not meant to be used in production.\n\u003e\n\u003e **Note:** I choose to use `nextjs` to test React 19 features since some features need a React framework to work.\n\n## How to use\n\n1. Clone the repository\n2. Install the dependencies\n3. Run the project:\n\n```bash\nnpm run dev\n```\n\n## React Compiler\n\nReact 19 introduces a new experimental compiler that automatically memoizes your code. This greatly reduces the need to use `useMemo`, `useCallback`, and `React.memo`.\n\nTo test the new compiler in your Next.js 15 RC project, you need to add the following configuration to your `next.config.js` file:\n\n```js\nconst nextConfig = {\n  experimental: {\n    reactCompiler: true,\n  },\n}\n\nexport default nextConfig\n```\n\n\u003e Note: Check the Next.js documentation for updated information on how to use the React Compiler in Next.js. The above configuration may change in the future since we are using a beta version of Next.js (Next.js 15 RC) at the time of writing this document\n\n## Resources\n\n- [React 19](https://react.dev/blog/2024/04/25/react-19)\n- [React 19 on Medium](https://medium.com/@hassan.djirdeh/react-19-beta-is-out-4d41aa1d4eee)\n- [React Compiler](https://19.react.dev/learn/react-compiler)\n- [Next.js](https://nextjs.org/)\n\n## License\n\n- [MIT](LICENSE.md)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Femanuelefavero%2Freact-19","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Femanuelefavero%2Freact-19","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Femanuelefavero%2Freact-19/lists"}
