To optimize React and Next.js performance, apply over 40 category-based rules covering API routes, server components, client data fetching, and bundle optimization to reduce latency and bundle size.

Reducing Next.js bundle size involves applying bundle optimization rules that prioritize code splitting, minimize client-side payloads, and leverage server components to offload rendering work.

Fixing client-side data fetching waterfalls requires moving data fetching to server components or parallelizing client requests, aligning with guidelines to minimize sequential loading delays.

Yes, this approach works for both client-side and server-side React patterns, providing concrete examples and metrics to guide refactoring across API routes, server components, and client fetching.

Prioritize Next.js server components when you need to reduce client bundle size and minimize data fetching waterfalls, reserving client components for interactivity requiring browser APIs.
