Measured entry

tripled-shimmer-button-shadcnui

buttongradient-glowmotion on file

A client-side call-to-action button with a continuously animated gradient sweep and reduced-motion handling. It ships as a shadcn registry component, wraps the project-local shadcn Button, and depends on React, Framer Motion, theme tokens, and the underlying Radix-based button stack.

Verdict

A sound accent button for an existing shadcn app, with sensible reduced-motion behavior and clean rendering. It is not portable as-is: it needs a shadcn-style setup, and its fixed label and closed API make source edits necessary for normal product use.

Use it if

  • You need a prominent call to action with a restrained looping shimmer.
  • Your app already uses shadcn conventions, theme tokens, and the local Button component.
  • You want motion that automatically stops for visitors who prefer reduced motion.

Skip it if

  • You need a drop-in button for a plain React project with no shadcn component layer.
  • You want configurable text, variants, event handlers, or forwarded button props without editing the source.
  • Your interface avoids perpetual motion or cannot justify adding Framer Motion for one effect.

Providerno provider required in the harness

In a non-shadcn project, add React and Framer Motion, provide a compatible local Button component, configure the at-sign path alias, add the shared class-name utility used by that button, and define the accent theme tokens referenced by the styles. Then expose props for the label and button behavior as needed.
