## What it is
A Ruby gem that integrates React.js into Ruby on Rails applications, supporting server-side and client-side rendering with views, controllers, and asset pipelines like Sprockets, Propshaft, and Shakapacker. It allows writing React components in JSX, ES6, TypeScript, or CoffeeScript within Rails projects.

## Use cases
- render React components inside Rails views
- server-side render React in a Rails app
- use JSX with the Rails asset pipeline
- mount React components via Sprockets or Shakapacker
- add React to an existing Rails monolith
- wire React components to Rails controllers and props

## When to choose
- you have an existing Rails app and want to add React components incrementally
- you use Sprockets, Propshaft, or Shakapacker and want React integration
- you need simple server-side rendering of React within Rails views

## When to avoid
- you are starting a new project and want active development and modern React features like Server Components - prefer React on Rails
- you need a dedicated Node-based rendering pipeline with TypeScript support
- your frontend is a separate SPA not embedded in Rails views

## Facets
- artifact type: library
- maturity: maintenance
- function: ssr, templating, frontend-framework, middleware
- domain: web-development, frontend, developer-tools
- platform: ruby
- tags: react, rails, ruby-gem, server-side-rendering, jsx, webpacker, sprockets, shakapacker, nodejs, web-server
