React and Next.js performance optimization involves applying 70 prioritized rules across 8 categories that guide automated refactoring for data fetching, rendering, and bundle size reduction to improve initial load and runtime speed.

Best practices for React data fetching and bundle optimization include applying proven patterns for caching, rendering, and bundling that target initial load and interactivity improvements during automated code generation and refactoring.

Yes, these Next.js performance rules are designed to guide both automated refactoring of existing UI components and new code generation, prioritizing impact to fix common bottlenecks in data fetching and rendering workflows.

Slow hydration and large bundle sizes in Next.js apps result from common bottlenecks that 70 prioritized best-practice rules address by consolidating clear patterns for rendering, data fetching, and bundle optimization.

This skill covers general React and Next.js optimization rules applicable across deployments, consolidating 70 proven guidelines across 8 priority categories to improve caching, interactivity, and runtime performance.

You should apply Next.js performance refactoring rules when building or refactoring UI components, data fetching workflows, and bundle optimization tasks to identify and fix performance bottlenecks in large React applications.
