Deploying React Applications

Build, deploy, and operate React apps in production with CI/CD and runtime best practices.

Production build

bash

npm run build

For Vite apps, output is generated in dist/.

Deployment targets

Vercel
Netlify
AWS S3 + CloudFront
Docker + Nginx

SPA routing fallback

Configure server rewrites so unknown routes return index.html.

Environment configuration

Keep secrets outside frontend bundles
Use environment variables for API base URLs
Separate development and production configs

CI/CD checklist

Task	Action
Lint	`npm run lint`
Tests	`npm run test`
Build	`npm run build`
Security	dependency and audit checks
Deploy	platform-specific release step
Monitor	error tracking and performance metrics

Final summary

You now have a complete React learning path covering setup, core concepts, hooks, routing, forms, state management, testing, performance, accessibility, and deployment.

Keep practicing by building projects such as:

Task manager with authentication
E-commerce frontend with cart and checkout flow
Admin dashboard with role-based access and analytics
