React on Rails integrates Rails with (server rendering of) Facebook's React front-end framework.

This project is maintained by the software consulting firm ShakaCode. We focus on Ruby on Rails applications with React front-ends, often using TypeScript or ReScript (ReasonML). We also build React Native apps and Gatsby sites. See our recent work for examples of what we do. ShakaCode.com (HiChee.com) is hiring developers that like working on open-source.

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. Check out React on Rails Pro.

Feel free to contact Justin Gordon, [email protected], maintainer of React on Rails, for more information.

Project Objective

To provide a high performance framework for integrating Ruby on Rails with React via the Webpacker gem especially in regards to React Server-Side Rendering for better SEO and improved performance.

Features and Why React on Rails?

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

  1. 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.
  2. Tight integration with rails/webpacker.
  3. Server-Side Rendering (SSR), often used for SEO crawler indexing and UX performance, is not offered by rails/webpacker.
  4. Redux and React Router integration with server-side-rendering.
  5. Internationalization (I18n) and (localization)
  6. A supportive community. This web search shows how live public sites are using React on Rails.
  7. Reason ML Support.

See Rails/Webpacker React Integration Options for comparisons to other gems.

See the react-webpack-rails-tutorial for an example of a live implementation and code.

The following companies support this open source project, and ShakaCode uses their products! Justin writes React on Rails on RubyMine. We use Scout to monitor the live performance of HiChee.com, Rails AutoScale to scale the dynos of HiChee, and HoneyBadger to monitor application errors. We love BrowserStack to solve problems with oddball browsers. Status Hero keeps the team posted on daily progress; it's so much better than live standups.
