Type-safe, file-based React routing with route loaders, search params validation, code splitting, preloading, navigation, route context, and TanStack Query integration. Use when setting up file-based routing, adding search params validation, implementing route loaders, code splitting routes, configuring virtual file routes, protecting routes with auth guards, or fixing type registration errors. Use for router setup, navigation patterns, URL state management, data loading.
Explains JavaScript bundling, code splitting, chunking strategies, tree shaking, and build pipelines. Use when optimizing bundle size, understanding how modern build tools work, configuring Webpack/Vite/esbuild, or debugging build output.
Reduces JS/TS bundle size via unused deps, tree-shaking, code splitting with keep/discard
WHEN: Performance analysis, bundle size optimization, rendering, Core Web Vitals, code splitting WHAT: Bundle analysis + large dependency detection + re-render issues + useMemo/useCallback suggestions + LCP/FID/CLS improvements WHEN NOT: Code quality → code-reviewer, Security → security-scanner
React/Next.js 앱의 성능을 분석하고 최적화하는 스킬. 번들 사이즈, 렌더링 최적화, 코드 분할, 이미지 최적화, SSR/SSG 전략 등. "성능", "performance", "최적화", "느려", "번들 사이즈", "렌더링" 등의 요청 시 사용.
Optimize React apps for 60fps performance. Implements memoization, virtualization, code splitting, bundle optimization. Use for slow renders, large lists, bundle bloat. Activate on "React performance", "slow render", "useMemo", "bundle size", "virtualization". NOT for backend optimization, non-React frameworks, or premature optimization.
Code splitting and lazy loading with React.lazy, Suspense, route-based splitting, intersection observer, and preload strategies for optimal bundle performance. Use when implementing lazy loading or preloading.
Provides comprehensive guidance for Webpack bundler including configuration, loaders, plugins, code splitting, optimization, and development setup. Use when the user asks about Webpack, needs to configure Webpack, set up build pipelines, optimize bundles, or work with Webpack plugins.
React performance optimization patterns - React.memo, useMemo, useCallback, code splitting, and preventing unnecessary re-renders
React performance optimization patterns including memoization, code splitting, bundle size reduction, re-render elimination, and profiling. Covers React Compiler automatic optimization, manual memo/useMemo/useCallback targeting, React.lazy with Suspense, barrel file avoidance, content-visibility for large lists, startTransition for non-urgent updates, and React DevTools profiling. Use when optimizing React app performance, reducing bundle size, eliminating unnecessary re-renders, debugging slow components, code splitting, or profiling rendering bottlenecks. Use for performance audit, bundle analysis, re-render diagnosis, lazy loading, virtualization.
Refactor high-complexity React components in frontend. Use when the user asks for code splitting, hook extraction, or complexity reduction, or when you come across a component that is too complex to understand and refactor it.
