To optimize React and Next.js performance during code review, apply rule-based best practices for component development, data fetching, code-splitting, and bundle optimization to identify bottlenecks and enable automated refactoring.

Best practices for reducing bundle size in Next.js involve applying code-splitting patterns and bundle optimization guidelines, which help safely refactor pages and server components to improve load times and user-perceived performance.

Using server components improves Next.js load times by shifting data fetching and rendering workloads to the server, following performance optimization patterns that reduce client-side bundle size and runtime overhead.

Yes, you can refactor existing React codebases safely by using structured guidelines and actionable rules to identify performance bottlenecks and apply recommended patterns quickly without breaking component logic.

The best way to identify performance bottlenecks in a React project is to review the codebase against consolidated performance best practices, allowing you to extract top optimization priorities for components and data fetching.

You should apply code-splitting in React and Next.js applications when optimizing component development and data fetching workflows to reduce initial bundle size, decrease load times, and improve overall user-perceived performance.
