What problem does it solve?
Vercel React Best Practices codifies common performance pitfalls and remediation patterns for React and Next.js projects so engineers and agents can identify and fix costly waterfalls, oversized bundles, and inefficient server/client data flows.
Core Features & Use Cases
- Comprehensive Ruleset: 58 rules across Eliminating Waterfalls, Bundle Size Optimization, Server-Side Performance, Client-Side Data Fetching, Re-render Optimization, Rendering Performance, JavaScript Performance, and Advanced Patterns.
- Actionable Guidance: Concrete incorrect vs correct examples, prioritized impact levels, and patterns for parallelization, dynamic imports, caching, and serialization minimization.
- Use Cases: Automated code review and refactoring, performance audits before release, educating engineers or agents on best practices, and generating performance-minded replacements for slow components or API routes.
Quick Start
Ask the skill to audit a React or Next.js file and produce prioritized, concrete refactors to eliminate waterfalls, reduce bundle size, and improve server/client data fetching.
