核心网页指标、懒加载、代码分割与包分析。
该技能专注于前端性能优化，涵盖核心网页指标（Core Web Vitals）、懒加载、代码分割、图片优化、包分析、缓存策略和数据库查询调优等关键领域。它提供了一个全面的性能优化规则集，适用于 Next.js、React 等现代前端框架，帮助开发者确保 LCP < 2.5s、INP < 200ms、CLS < 0.1 等指标达标。技能支持通过 React.lazy 和 next/dynamic 实现组件级懒加载，通过路由级代码分割减少首屏加载体积，并通过 WebP/AVIF 图片格式和 next/image 组件优化图片加载性能。此外，它还包括使用 @next/bundle-analyzer 进行包分析以识别大型依赖、HTTP 缓存头和 Service Worker 实现缓存策略、数据库索引优化和 EXPLAIN ANALYZE 慢查询排查，以及通过显式设置元素尺寸避免布局偏移等最佳实践。
