React and Next.js performance optimization involves applying curated patterns for code splitting, lazy loading, and server actions to improve runtime efficiency. These rules guide safe data fetching and rendering behavior to reduce waterfalls and accelerate initial paint.

Reduce Next.js bundle size and waterfalls by reviewing your project and applying documented patterns for code splitting and Suspense usage. This refactoring enforces concrete rules for data fetching and bundling to optimize initial loads.

Use Suspense and server actions in Next.js when you need to improve rendering behavior and runtime efficiency. Applying these patterns ensures safe serialization and helps developers reduce data-fetching waterfalls across components and pages.

This React optimization approach works for existing projects across teams by enforcing concrete refactoring rules for rendering, data fetching, and bundling. It guides developers to review and refactor code to ensure compliance with performance patterns.

Limitations of code splitting and lazy loading in React involve ensuring safe serialization and proper Suspense usage to avoid degrading reliability. Developers must apply these patterns carefully to prevent suboptimal rendering and maintain efficiency.
