To optimize React and Next.js performance during refactoring, apply structured guidelines covering server-side rendering, client-side data fetching, and bundle optimization. This enforces guardrails and safety checks to ensure robust improvements.

The best way to avoid data fetching waterfalls in Next.js is implementing parallel data fetching patterns. Deferring non-critical libraries also minimizes blocking and improves overall Time to Interactive metrics.

You need server-side rendering versus client-side rendering in Next.js when evaluating specific route data requirements. Applying rendering performance guidelines helps determine the optimal pattern for components and pages to improve metrics.

Improve bundle optimization in a React application by deferring non-critical libraries and applying established patterns. This reduces initial load size and directly improves First Input Delay and Cumulative Layout Shift scores.

Yes, you can use these React performance patterns for code reviews and audits on existing codebases. The guidelines provide ready-to-apply rules to validate server and client rendering patterns across both new and established projects.
