Vercel React Best Practices

What It Is

An official Vercel skill that packs 64 performance rules for React and Next.js into a format AI agents can follow. Covers rendering strategy, state management, component design, data fetching, performance optimization, type safety, accessibility, and testing. Install it in Claude Code and the AI writes code aligned with Vercel conventions without you prompting it.

What’s Actually Different

Writing “follow React best practices” in your prompt gives you inconsistent results that vary by model. This skill encodes 64 specific, conditional rules from Vercel’s team — they don’t drift. More importantly, these rules are Next.js-aware: Server Components, App Router, use cache, and other framework-specific patterns that generic React advice ignores. The rules tell the AI not just what to do, but when and why.

Who It’s For

Anyone building with Next.js or React who wants their AI assistant to write convention-aligned code from the start. Most valuable if you deploy on Vercel, since these rules match the platform’s recommended patterns. Less useful for non-Next.js React projects (though the rendering and state management rules still apply).

Bottom Line

Vercel’s internal React expertise, packaged as an AI skill. Install once, every Claude Code session benefits.
