Animate SVG Wrapper Instead of SVG Element

Many browsers don't have hardware acceleration for CSS3 animations on SVG elements. Wrap SVG in a <div> and animate the wrapper instead.

Incorrect (animating SVG directly - no hardware acceleration):

function LoadingSpinner() {
  return (
    <svg className="animate-spin" width="24" height="24" viewBox="0 0 24 24">
      <circle cx="12" cy="12" r="10" stroke="currentColor" />
    </svg>
  );
}

Correct (animating wrapper div - hardware accelerated):

function LoadingSpinner() {
  return (
    <div className="animate-spin">
      <svg width="24" height="24" viewBox="0 0 24 24">
        <circle cx="12" cy="12" r="10" stroke="currentColor" />
      </svg>
    </div>
  );
}

This applies to all CSS transforms and transitions (transform, opacity, translate, scale, rotate). The wrapper div allows browsers to use GPU acceleration for smoother animations.

README badge for vercel-labs/openreview/vercel-react-best-practices

Provides 58 prioritized React and Next.js performance rules from Vercel Engineering, organized across waterfalls, bundle size, server/client data fetching, re-renders, and rendering patterns. Use when writing or refactoring React components and Next.js pages to apply production-grade optimization practices.

Generated from the current SKILL.md.

Does this skill apply to both React and Next.js?
Yes. The skill covers React components, Next.js pages, server components, server actions, and data fetching patterns for both frameworks.
Can I use this skill to review existing code for performance issues?
Yes. The skill is designed for reviewing and refactoring React/Next.js code against 58 prioritized rules organized by impact (critical, high, medium, low).
Does this skill cover bundle size optimization?
Yes. Bundle size optimization is marked as a critical priority category with 5 rules, including barrel imports, dynamic imports, and third-party script deferral.
What about server-side performance and data fetching?
The skill covers both. It includes rules for server components, React.cache(), LRU caching, parallel fetching, and client-side patterns like SWR deduplication and event listener optimization.
