Does this skill support Next.js specific optimizations?

Yes, it covers Next.js specific features like the Image component for automatic layout shift prevention and optimized asset delivery.

When should I use React.memo instead of standard components?

Use React.memo when a component renders frequently with the same props and is expensive to re-render. It is most effective when the parent component re-renders often but the child's data remains stable.

How do I fix unnecessary re-renders caused by object props?

The skill suggests using useMemo for stable object references or extracting primitive values in dependency arrays to prevent infinite loops and redundant render cycles.

Does this skill provide guidance on list virtualization?

Yes, it includes implementation patterns for virtualization (like @tanstack/react-virtual) which ensures only the items currently in the viewport are rendered, significantly improving performance for long lists.

Developer Tools

Optimizes React application speed and efficiency using memoization, code splitting, and advanced rendering techniques.

About

This skill empowers Claude to identify and resolve React performance bottlenecks through a comprehensive set of industry-standard optimization patterns. It provides specific guidance on implementing memoization via React.memo, useMemo, and useCallback, reducing bundle sizes through code splitting, and managing high-density data with virtualization. Following the 'Measure First' philosophy, this skill helps developers fix rendering lags, optimize state management, and improve Core Web Vitals without introducing unnecessary architectural complexity.
