vercel-react-best-practices

To identify React and Next.js performance bottlenecks during a code review, evaluate code against Vercel's best-practice patterns covering eight categories like eliminating waterfalls, bundle size optimization, and re-render optimization to detect and resolve suboptimal rendering and data fetching.

Best practices for reducing bundle size and client-side data fetching in Next.js include applying concrete rules for precise data fetching, eliminating waterfall requests, and enforcing safe defaults to improve Time to Interactive, FID, and LCP metrics.

Server-side performance optimization in React and Next.js works by applying Vercel's best-practice guidelines to improve server-side rendering and precise data fetching, which helps reduce waterfalls and overall bundle size for better UX.

Yes, you can use these React performance refactoring guidelines to improve LCP and FID metrics, as the skill provides real-world refactoring guidance and actionable patterns specifically designed to enhance Time to Interactive and overall UX in Next.js projects.

To optimize React re-rendering and rendering performance when refactoring frontend projects, apply the skill's concrete rules and advanced patterns for careful re-rendering with safe defaults, addressing both JavaScript performance and client rendering concerns.
