performance-optimization

Improve Core Web Vitals by running Lighthouse audits, analyzing your bundle, and configuring caching strategies. Implement code splitting, lazy loading, and image optimization to target LCP, FID/INP, and CLS metrics directly.

Profile web performance by running Lighthouse via command line to generate JSON reports and using webpack-bundle-analyzer to inspect build output. Execute builds with analysis flags enabled to visualize and identify heavy dependencies.

The best way to reduce bundle size is implementing code splitting and lazy loading for your routes and components. Use bundle analysis tools to identify large modules and split them into smaller, on-demand loaded chunks.

Yes, this optimization approach serves both frontend and backend teams. Frontend efforts focus on code splitting and images, while backend work involves configuring server and CDN caching strategies to reduce latency.

Caching strategy configuration improves LCP and CLS scores by serving static assets faster via browser and CDN caches. Effective caching reduces server response times and layout shifts by ensuring resources load predictably.

Avoid code splitting for small applications where the overhead of multiple network requests outweighs the benefit of smaller chunks. If bundle analysis shows a minimal footprint, a single bundled file may load faster.
