Performance Optimization Skill

Purpose

Expert knowledge in optimizing web performance focusing on Core Web Vitals, bundle size reduction, and efficient caching strategies.

Core Principles

  1. Measure First - Use Lighthouse/PageSpeed Insights
  2. Core Web Vitals - LCP < 2.5s, FID < 100ms, CLS < 0.1
  3. Progressive Enhancement - Core functionality works everywhere
  4. Lazy Loading - Load content as needed
  5. Caching Strategy - Maximize cache hits

Enforces

  • Core Web Vitals targets:
    • LCP (Largest Contentful Paint) < 2.5s
    • FID (First Input Delay) < 100ms
    • CLS (Cumulative Layout Shift) < 0.1
  • Bundle size optimization (< 100KB initial)
  • Image optimization (WebP, lazy loading)
