React on Rails Tutorial

A cleaner way to explore Rails, React, and server rendering together.

Start with the live demo, then branch into the React on Rails gem and Shakapacker gem integration patterns without digging through a wall of docs first.

React-only Route Classic Rails README

This Demo Covers

Server rendering and hydration.
React Router transitions and redirects.
Live comments over Action Cable.

Review Apps

Three commands, one preview environment.

Use control-plane-flow to deploy, inspect, or remove a PR preview without leaving the thread.

Why this workflow matters

The review-app flow turns deployment into a lightweight PR action instead of a separate setup task.

Classic Rails No Router React

React Router Demo

The same comments app, with routing.

Use the pills to view the comments route, a plain routed screen, and a redirect back to root.

What this demo proves

Server render first, then hydrate on the client.
Keep routing and comments in the same Redux-backed flow.
Verify redirects still resolve cleanly after SSR.

Route Example

React Router is working!

This route swaps the content area without leaving the router-enabled demo shell.
