To fix React performance issues, review component design and rendering behavior to apply proven refactoring patterns that reduce re-renders and keep interactions responsive. This process targets component structure to eliminate janky UI behavior.

Optimizing bundle size in a Next.js application involves improving load times through better import patterns, dynamic loading, and statically analyzable paths. This refactoring approach reduces initial bundle weight for faster page loads.

Avoiding data fetching waterfalls requires applying rules for caching, serialization, and immutability to guide safe changes. Refactoring Next.js routes and actions improves concurrency and response time without altering business logic.

Yes, you can safely handle server-side fetching, caching, and serialization alongside client-side state patterns. This guidance ensures secure, high-impact changes to server and client workflows in production web applications.

Refactoring React code for performance requires careful adherence to rules for serialization and immutability to prevent unsafe changes. Limitations arise when altering rendering behavior or server action workflows without maintaining business logic integrity.

You need to review React or Next.js code for performance optimizations when a page feels sluggish or before slow builds and janky UIs occur. Targeted changes improve data fetching, component structure, and rendering behavior.
