Explanation

A production-ready React application should use an optimized build rather than the development server. Build the application and deploy only the required output files.

Code:

npm ci
npm run build

# Deploy the generated directory
dist/

Explanation

Use HTTPS to protect data transferred between users and the application. CloudFront can use an AWS Certificate Manager certificate for a custom domain.

Code:

Production URL:
https://www.example.com

Recommended:
CloudFront + ACM certificate + custom domain

Explanation

Monitor application availability, API failures, and frontend errors. AWS services such as CloudWatch can help track infrastructure and backend behavior.

Code:

Monitor:
- CloudFront errors
- API Gateway 4xx and 5xx responses
- Lambda execution errors
- Application performance
- Deployment failures

Explanation

Optimize bundle size and loading performance using lazy loading, code splitting, image optimization, and memoization where appropriate.

Code:

import { lazy, Suspense } from 'react';

const ReportsPage = lazy(() => import('./ReportsPage'));

function App() {
  return (
    <Suspense fallback={<p>Loading...</p>}>
      <ReportsPage />
    </Suspense>
  );
}

Explanation

Before releasing a React application, verify security, routing, caching, monitoring, and rollback procedures. A checklist reduces deployment mistakes.

Code:

Production checklist:
- Build succeeds
- Tests pass
- HTTPS is enabled
- API CORS is configured
- Secrets are not exposed
- React routes work after refresh
- CloudFront cache is managed
- Monitoring is enabled
- Rollback plan is available
