Marketplace — RSC performance demo
A marketplace built on Pro + RSC, with Lighthouse reports and bundle-size evidence you can inspect.
An additive layer on open-source React on Rails
React on Rails Pro
Pro adds React Server Components, streaming SSR, concurrent and cached rendering, and a dedicated Node renderer on top of the open-source gem. The gem and npm package are public — install and build today under ShakaCode Trust-Based Commercial Licensing.
bundle add react_on_rails_proFree to learn. Paid for private business value.No token is required for development, test, CI/CD, and staging, plus demos, education, or qualifying open-source projects. Production use that creates private business value requires a paid React on Rails Pro license.
What Pro adds
Every feature below ships in the public Pro gem. Trust-based commercial licensing covers production use and support — not access to evaluate the package.
React Server Components
Render React Server Components from Rails and stream their payload to the browser, shipping interactive UI with dramatically less client JavaScript.
Streaming SSR with immediate hydration
stream_react_component flushes server-rendered HTML as each Suspense boundary resolves, and every piece hydrates the moment it streams in — first paint never waits on the slowest data, and the page turns interactive sooner.
Concurrent component rendering
async_react_component renders multiple components in parallel through the Node renderer instead of one after another, cutting response time on component-heavy pages.
Streaming-aware caching
Fragment-cache rendered output — including streamed components — and add prerender caching so cache hits skip props, serialization, and JS execution entirely.
Dedicated Node renderer
A concurrent Fastify-based Node.js renderer pool delivers higher SSR throughput than single-threaded ExecJS, and powers RSC, streaming, and parallel rendering.
Code splitting + bundle caching
Loadable-component code splitting with SSR-aware bundle caching keeps large client bundles fast to build and ship.
See it running, read the source
Both demos are public — live apps and full source. Inspect the performance evidence and the code before you talk to us about a license.
TanStack starter — Rails-centered React
Keep Rails at the center and use Pro for the React paths that need Node: RSC and streaming on public pages, SSR with TanStack Router and Table on app surfaces.
Upgrade path
Three steps to build with Pro
- 1Add the gem and package
Add react_on_rails_pro and the Node renderer npm package — both public on RubyGems and npm, no account needed to start.
- 2Turn on the features you need
Enable RSC, streaming SSR, fragment caching, or the Node renderer on the paths where they actually help.
- 3Align licensing before production
Confirm production rendering and performance on the paths that matter, then add a paid license before private business value ships.
Trust-Based Commercial Licensing
Free to learn. Paid when it creates private business value.
React on Rails Pro uses ShakaCode Trust-Based Commercial Licensing: free for learning, demos, tutorials, education, and qualifying OSS; paid for production use that creates private business value. Visit Pro pricing and sign up for current options.
The umbrella philosophy is separate from the legal terms: production use remains governed by the React on Rails Pro EULA. Budget-constrained? Email justin@shakacode.com about free or low-cost licenses in qualifying cases.
