React + Rails: A Proven Production Stack
The React + Rails combination powers thousands of production applications — from Y Combinator startups to Fortune 500 companies. Rails handles business logic, data, and authentication, while React delivers fast, interactive user interfaces.
Architecture Options
Option 1: Separate Repos — Rails API and React app in separate repositories. Best for teams and independent scaling.
Option 2: Rails Monolith — React embedded in Rails via esbuild/jsbundling. Simpler deployment, shared authentication.
API Design Patterns
Use Blueprinter for JSON serialization, Pagy for pagination, and return consistent response formats with data and meta keys.
Authentication
For SSR (Next.js), use httponly cookies. For SPAs, JWT with refresh tokens and Axios interceptors for automatic token renewal.
TypeScript + Rails
Generate TypeScript types from your Rails serializers for end-to-end type safety.
Deployment
- Rails API: Kamal or Docker on VPS
- React SPA: Vercel, Netlify, or CloudFront + S3
- Next.js: Vercel (optimal) or self-hosted
