1. Push your code to GitHub
2. Import project in Vercel
3. Set environment variable: REACT_APP_API_URL
4. Deploy!

npm install -g vercel
vercel login
vercel

Set in Vercel dashboard or .env.production:

REACT_APP_API_URL=https://your-backend.railway.app/api

npm run build

Creates optimized production build in build/ directory.

Ensure backend FRONTEND_URL matches your deployed frontend URL.

For Vercel, the vercel.json config handles SPA routing. For other hosts, configure redirects to /index.html.

Check that REACT_APP_API_URL is correct and backend is running.
