react-best-practices

React and Next.js performance optimization best practices include eliminating data waterfalls, reducing bundle size, and optimizing server-side rendering. These guidelines span eight categories with concrete examples covering both client and server workflows.

To reduce bundle size and improve rendering speed in Next.js, apply practical patterns for efficient data fetching and server-side performance. Implementing rules from these categories during component building or refactoring yields faster load speeds.

Yes, you can use these React performance guidelines during code reviews. They provide practical patterns and references that enforce efficient rendering, reduced bundle size, and optimal data fetching across client and server components.

No, you do not need proprietary tooling to optimize React and Next.js app performance. These guidelines require only standard React and Next.js workflows, enforcing practical patterns without any additional specialized software dependencies.

React performance guidelines cover eight categories: eliminating waterfalls, bundle size optimization, server-side performance, client-side data fetching, re-render optimization, rendering performance, JavaScript performance, and advanced patterns.

Server-side rendering may not be optimal when it introduces data fetching waterfalls. The guidelines address this by providing patterns for client-side data fetching and advanced rendering techniques to balance server and client performance.
