What problem does it solve? React and Next.js applications often suffer from slow load times, unnecessary re-renders, bloated bundles, and async waterfalls that degrade user experience. This Skill provides a structured, prioritized rule set so AI agents and developers can systematically identify and fix performance issues during code generation, review, and refactoring. ## Core Features & Use Cases - 57 Prioritized Rules Across 8 Categories: Covers eliminating waterfalls, bundle size optimization, server-side performance, client-side data fetching, re-render optimization, rendering performance, JavaScript micro-optimizations, and advanced patterns, each tagged with an impact level from CRITICAL to LOW. - Incorrect vs. Correct Code Examples: Every rule includes concrete TypeScript/TSX examples showing the anti-pattern and the optimized implementation, with impact metrics like 2-10x improvements or 200-800ms import cost reductions. - Use Case: When reviewing a Next.js page that fetches user, posts, and comments sequentially, apply the async-parallel rule to rewrite the fetches with Promise.all(), cutting three network round trips down to one. ## Quick Start Ask the AI to review your React component or Next.js page for performance issues using the react-best-practices guidelines and apply the highest-impact fixes first.
