Optimizing React and Next.js performance involves applying a structured rule set covering async data fetching, bundle optimization, and server-side rendering. This approach uses categorized priorities and real-world examples to guide safe refactoring and maximize user-perceived performance metrics like TTI and LCP.

To reduce bundle size during a React refactor, apply structured best practices for bundle optimization. This involves using real-world examples and safe patterns to guide automated changes, ensuring reproducible improvements without introducing regressions to the component rendering logic.

Yes, this best practices guide covers server-side performance for Next.js pages. It provides categorized rules and actionable patterns for data fetching strategies and server-side rendering, helping teams accelerate performance-focused decisions and prevent server-side regressions.

Yes, you can use these React performance rules for automated code reviews. The guidelines are designed to ensure high-performance applications by providing a centralized, scalable rule set that helps teams consistently evaluate code and prevent regressions during review.

The best way to start a React performance refactor is to audit the codebase by checking waterfalls, bundle size, and server performance first. Then, implement prioritized patterns in a staged refactor, beginning with the highest-impact rules to ensure safe, reproducible changes.
