ReactBundle integrates ReactRenderer with Symfony. This lets you implement React.js client and server-side rendering in your Symfony projects, allowing the development of universal (isomorphic) applications.

Note: If you are new to React.js, please note that this bundle is not by any means required to use React with Symfony. This allows you to do some advanced features such as Server Side Rendering, or injecting components directly from Twig tags.

Features include:

  • Prerender server-side React components for SEO, faster page loading, and users that have disabled JavaScript.
  • Twig integration.
  • Client-side render will take the server-side rendered DOM, recognize it, and take control over it without rendering again the component until needed.
  • Error and debug management for server and client side code.
  • Simple integration with Webpack.
