To optimize React and Next.js performance during refactoring, apply priority-based rules across 8 categories covering server/client rendering, data fetching, and bundle optimization to guide automated code generation and reduce waterfalls.

Best practices for reducing bundle size in Next.js involve applying bundle optimization patterns from Vercel engineering guidelines, which enforce safe code-generation constraints to shrink bundles and ensure scalable, auditable improvements.

Server and client rendering optimization in React works by applying explicit frontmatter metadata and priority-driven rules to categorize and enforce rendering patterns, ensuring faster and more reliable data fetching across components.

Yes, you can use these React and Next.js performance patterns for automated code generation, as the guidelines enforce safe constraints and priority-based categories to ensure scalable and auditable refactoring outputs.

You need to apply data fetching optimization patterns in Next.js when writing, reviewing, or refactoring pages and performance-sensitive code to reduce waterfalls and improve server and client rendering efficiency.
