How does it improve bundle sizes?

The skill identifies opportunities for dynamic imports, warns against heavy barrel files, and suggests deferring third-party scripts to optimize the initial hydration phase.

Can this skill help with Next.js App Router optimization?

Yes, it includes specific guidelines for server-side performance, data fetching, and streaming using Suspense boundaries tailored for modern Next.js architectures.

Is this skill useful for existing projects?

Absolutely. It is specifically designed for refactoring and reviewing existing codebases to find and fix performance bottlenecks like async waterfalls and excessive re-renders.

What does the Vercel React Best Practices skill do?

It provides Claude with a set of 45 performance-oriented rules to optimize React and Next.js code for speed, efficiency, and better user experience.

Developer Tools

Optimizes React and Next.js application performance using Vercel Engineering's production-grade guidelines and implementation patterns.

About

This skill integrates Vercel's comprehensive performance optimization framework directly into your development workflow. It provides Claude with 45 specific rules across eight critical categories—from eliminating async waterfalls and optimizing bundle sizes to fine-tuning server-side rendering and reducing unnecessary re-renders. By applying these standards during code generation, reviews, or refactoring, developers can ensure their React and Next.js applications meet high-performance benchmarks for speed, Core Web Vitals, and efficient resource utilization.

Key Features

Optimizes JavaScript bundle sizes through dynamic imports and barrel file removal
Improves server-side performance using React cache and serialization best practices
3 GitHub stars
Reduces client-side re-renders by implementing memoization and derived state patterns
Eliminates asynchronous waterfalls with parallelized data fetching patterns
Enhances rendering performance through content-visibility and static JSX hoisting

Use Cases

Refactoring existing Next.js pages to improve Core Web Vitals and load times
Conducting performance-focused code reviews for complex React component hierarchies
Implementing efficient data fetching strategies in both Server and Client Components
