| Resource ID | Type | Environment | Blockers |
|---|---|---|---|
| frontend-app | compute | dev | deprecated, no-containerization |
đ¯ Migration Strategy
Update dependencies, config scaffolding, and align scripts.
- Replace deprecated React lifecycle methods with hooks where applicable
- Prefer functional components over classes
- Replace default exports with named exports for tree-shaking
Run ESLint/TypeScript checks to ensure safe deployment.
Upload built assets to AWS S3 for static hosting.
đĻ Dependency Updates
- â dependencies.react (16.x â 18.3.1)
- â dependencies.react-dom (16.x â 18.3.1)
- â devDependencies.typescript (â 5.6.3)
â Quality Gates
đ¨ Build Results
âī¸ Deployment Status
đ° Cost Optimization Recommendations
Implement S3 lifecycle policies to transition infrequently accessed files to cheaper storage tiers
Add CloudFront CDN to reduce S3 request costs and improve global performance
Implement browser and edge caching to reduce origin requests by 70%
Enable gzip/brotli compression to reduce bandwidth costs by 60%
⥠Performance Optimization Recommendations
Distribute content via CDN edge locations for 50-70% faster global load times
Implementation Guide
Configure CloudFront distribution with S3 origin, enable all edge locations
Implement responsive images and modern formats (WebP, AVIF) to reduce payload by 40%
Implementation Guide
Use next/image or similar, implement picture elements with source sets
Implement route-based code splitting to reduce initial bundle size by 60%
Implementation Guide
Use React.lazy() and Suspense for route components, analyze bundle with webpack-bundle-analyzer
Add for critical resources to improve perceived performance
Implementation Guide
Identify critical routes and assets, add prefetch hints in HTML head
Implement service worker for offline capability and instant repeat visits
Implementation Guide
Use Workbox for React apps, configure cache strategies for static and dynamic content
đ Security Enhancement Recommendations
Enforce HTTPS for all traffic using CloudFront with ACM certificate
Create CloudFront distribution with custom SSL certificate, redirect HTTP to HTTPS
Enable S3 bucket encryption at rest and block public ACLs
Enable default encryption with AES-256 or KMS, set BucketPublicAccessBlock
Implement Content Security Policy headers to prevent XSS attacks
Configure CloudFront to add CSP headers: default-src 'self'; script-src 'self' 'unsafe-inline'
Add security headers (X-Frame-Options, X-Content-Type-Options, Referrer-Policy)
Configure response headers in CloudFront or Lambda@Edge function
Set up automated dependency vulnerability scanning in CI/CD
Integrate npm audit or Snyk into GitHub Actions workflow
Enable AWS WAF to protect against common web exploits
Attach AWS WAF WebACL to CloudFront distribution with AWS Managed Rules
