These are the docs for React on Rails 13. To see the older docs: v12 and v11.

React on Rails integrates Rails with (server rendering of) React.

This project is maintained by ShakaCode.

ShakaCode focuses on helping Ruby on Rails teams better use React and Webpack. We can upgrade your project and improve your development and customer experiences, allowing you to focus on building new features or fixing bugs instead.

For an overview of working with us, see our Client Engagement Model article and how we bill for time.

We also specialize in helping development teams lower infrastructure and CI costs. Check out our project Control Plane Flow, which can allow you to get the ease of Heroku with the power of Kubernetes and big cost savings.

Are you interested in optimizing your webpack setup for React on Rails, including code splitting with react-router and loadable-components with server-side rendering for SEO and hot-reloading for developers? We did this for Popmenu, lowering Heroku costs 20-25% while getting a 73% decrease in average response times. Several years later, Popmenu serves tens of millions of SSR requests daily with React on Rails Pro.

To provide a high-performance framework for integrating Ruby on Rails with React, especially regarding React Server-Side Rendering for better SEO and improved performance.

Given that shakacode/shakapacker gem already provides basic React integration, why would you use "React on Rails"?

1. Automatic configuration of what bundles are added to the page based on what React components are on the page. This results in faster browser loading time via smaller bundle sizes.
2. Keep up with the latest changes in different versions of React. React 18 is supported.
3. Easy passing of props directly from your Rails view to your React components rather than having your Rails view load and then make a separate request to your API. Tight integration with shakapacker (or its predecessor rails/webpacker).
4. Server-Side Rendering (SSR), often used for SEO crawler indexing and UX performance.
5. Automated optimized entry-point creation and bundle inclusion when placing a component on a page. With this feature, you no longer need to configure javascript_pack_tags and stylesheet_pack_tags on your layouts based on what’s shown. “It just works!”
6. Redux and React Router integration with server-side-rendering.
7. Internationalization (I18n) and (localization)
8. A supportive community. This web search shows how live public sites are using React on Rails.
9. ReScript Support.
