Optimize React bundle size by using dynamic imports to code-split non-critical components. This prevents large dependencies from bloating the initial JavaScript payload, ensuring faster page loads for Next.js applications.

Place Suspense boundaries strategically around components that suspend during server rendering to defer non-critical work. This allows the page to stream HTML progressively, improving perceived performance while maintaining robust data fetching patterns.

Vercel's best practices for server and client serialization require careful data passing between server and client components to avoid excessive payload transfer. Proper serialization maintains robust performance and prevents hydration mismatches in Next.js.

You can audit an existing Next.js project using these React performance best practices to evaluate components and implement refactors. The guidelines cover eight categories, helping identify and fix waterfalls, bundle bloat, and server rendering edge cases.
