Measured entry

magicui-pulsating-button

buttondark-futuristicmotion on file

A React client button with pulse and ripple variants driven by CSS custom properties and registry-supplied keyframes. It ships as a shadcn registry component, uses Tailwind theme classes and an aliased cn helper, and relies on clsx plus tailwind-merge through that helper.

Verdict

A focused attention cue that builds and mounts cleanly in its intended environment and exposes useful styling controls. It needs a shadcn-style setup, since the bare project cannot resolve its aliased cn utility. Best used sparingly for a primary action.

Use it if

  • You need a prominent call to action whose pulse color, pace, and spread can be tuned.
  • Your React and Tailwind app already follows shadcn aliases, theme tokens, and registry CSS conventions.
  • You want native button props and ref forwarding without adding an animation library.

Skip it if

  • Your interface should avoid continuously moving calls to action or does not yet provide a reduced-motion policy.
  • You need a drop-in component for plain React without Tailwind theme wiring and path aliases.
  • Your browser support cannot rely on modern relative color syntax used by the default pulse color.

Providerno provider required in the harness

In a non-shadcn project, add React client-component support, Tailwind, the semantic primary color utilities, the registry keyframes and animation utilities, and an alias-backed cn helper using clsx and tailwind-merge. Alternatively, replace the alias import and class composition with local equivalents.
