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 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.
Use when React performance optimization including memoization, lazy loading, and virtualization. Use when optimizing React applications.
Performance patterns for Apollo caching, Redis, and CloudFront optimization
Cloudflare Workers performance optimization with CPU, memory, caching, bundle size. Use for slow workers, high latency, cold starts, or encountering CPU limits, memory issues, timeout errors.
Reduces JS/TS bundle size via unused deps, tree-shaking, code splitting with keep/discard
Create optimized production bundles with Bun's native bundler. Use when building applications for production, optimizing bundle sizes, setting up multi-environment builds, or replacing webpack/esbuild/rollup.
Web Vitals, Lighthouse CI, bundle optimization, CDN, caching, and load testing
Coordinates code modernization: OSS replacement and bundle optimization workers
Use when optimizing application performance, reducing load times, improving database queries, meeting performance budgets, or diagnosing bottlenecks in web applications or APIs. Triggers: slow page loads, poor Web Vitals, database timeouts, large bundle size, user-reported sluggishness, scaling preparation.
Performance review and testing: evaluate Core Web Vitals, page load times, bundle sizes, runtime performance, resource optimization, and rendering efficiency with browser-based measurement and benchmarking.
