Measured entry

magicui-shimmer-button

buttonunclassifiedmotion on file

A React button with a traveling perimeter shimmer, hover and press feedback, and configurable color, timing, radius, and background. It ships as a shadcn registry TSX component, uses Tailwind utility classes and registry-provided keyframes, and imports the usual cn helper through the @ alias.

What the harness recorded

BARE BUILD

Verdict

A focused call-to-action effect with clean button semantics and useful visual controls. The verified project build and mount are healthy, but the bare import fails on the missing cn utility, so it needs a shadcn-style setup or a small manual adaptation.

Use it if

  • You need a prominent call-to-action on a dark hero or landing-page section.
  • Your React app already uses Tailwind and can absorb shadcn registry CSS variables and keyframes.
  • You want a native button that still accepts standard button props and a forwarded ref.

Skip it if

  • Your interface avoids continuously moving decoration or requires a built-in reduced-motion treatment.
  • You need a neutral button that works without Tailwind, custom keyframes, or project aliases.
  • Your design system cannot accommodate its dark default surface and animated perimeter treatment.

Providerno provider required in the harness

In a non-shadcn project, add a class-name merging helper or replace cn, change the @ alias import to a valid local path, ensure Tailwind processes the component classes, and copy the shimmer and spin keyframes plus their animation theme entries into your global styling setup. Add your own reduced-motion rule if required.
