Measured entry

magicui-shiny-button

buttongradient-glowmotion on file

A client-side React button shipped as a shadcn registry TSX file. It uses Motion for a looping shine and press response, Tailwind utility classes for appearance, a local cn class-merging helper, and the theme's primary CSS variable.

Verdict

A focused accent button that builds, mounts, and stays contained in the configured harness. It needs a shadcn-style setup because the bare project cannot resolve its local utility import. Best used sparingly for a primary action.

Use it if

  • You want an animated call-to-action that works across light and dark themes.
  • Your app already uses Tailwind, shadcn conventions, and Motion.
  • You need a real button element that accepts Motion and standard React props.

Skip it if

  • You want a dependency-free button or cannot justify adding Motion for one control.
  • Your design system does not use Tailwind utilities or shadcn path aliases.
  • You require animation to honor reduced-motion preferences without modifying the component.
  • A continuously moving highlight would distract from the surrounding interface.

In a non-shadcn project, install Motion, add a cn class-merging utility, configure the local import alias or replace it with a relative import, enable the Tailwind classes used here, and define the primary theme variable. Add a reduced-motion variant if your accessibility policy requires one.
