Frontend Performance Optimization

Overview

Comprehensive frontend performance optimization implementing React.memo across 30+ components, bundle analysis infrastructure, and performance monitoring tools to achieve sub-2-second load times.

Changes

• React.memo Optimization: Applied React.memo to all 30+ components preventing unnecessary re-renders
• Bundle Analysis: Added comprehensive bundle analyzer with webpack-bundle-analyzer, source-map-explorer, and lighthouse-ci integration
• Performance Monitoring: Implemented Core Web Vitals tracking (LCP, FID, CLS, TTFB) with historical data storage
• Performance Budgets: Configured budgets for bundle sizes and Core Web Vitals with CI enforcement
• Error Boundaries: Added comprehensive error handling to prevent cascade failures
• Documentation: Created performance optimization guide with best practices and troubleshooting
• CI Integration: Enhanced CI pipeline with performance testing and budget enforcement
• Code Quality: Fixed Prettier formatting issues

How to Test

1. Bundle Analysis: npm run bundle:analyze - Check bundle sizes against budgets
2. Performance Monitoring: npm run performance:monitor - Run Lighthouse CI audits
3. Web Vitals: npm run web-vitals:track - Monitor Core Web Vitals
4. Local Development: Verify dev server performance improvements
5. Storybook: Test component rendering performance

Notes

• Performance targets: LCP < 2.5s, FID < 100ms, CLS < 0.1, Bundle < 250KB
• Bundle analysis reports in coverage/ directory
• Performance budgets enforced in CI pipeline
• Monitoring dashboard available at /monitor
• Foundation for future optimizations (code splitting, lazy loading, image optimization)
