Measured entry

fancy-marquee-along-svg-path

scroll-effectspatialmotion on file

A React and TypeScript marquee that repeats arbitrary children along a supplied SVG path using CSS offset-path. It ships as a shadcn registry component, relies on Motion for frame, spring, scroll, and drag behavior, and imports a project-local cn utility alongside utility CSS classes.

Verdict

A flexible specialty effect with clean harness behavior and a broad interaction surface. It needs a shadcn-style setup to mount as supplied, and the hooks inside its item loop make dynamically changing the rendered item count a meaningful React risk.

Use it if

  • You need labels, logos, or decorative content to circulate along a custom curve.
  • Your interface benefits from optional scroll-reactive direction, hover slowdown, or pointer dragging.
  • Your project already uses a shadcn-style alias, utility classes, and Motion.

Skip it if

  • You need a lightweight static path treatment without a continuous animation dependency.
  • You require built-in reduced-motion behavior rather than adding that policy around the component.
  • The children or repeat setting must change dynamically, because hooks are created inside the rendered item loop.
  • You cannot rely on CSS motion-path support in your target browsers.

Providerno provider required in the harness

In a non-shadcn project, install Motion, replace or configure the project alias, provide a cn class-merging helper, and supply equivalents for the positioning and cursor utility classes. Mark the module as client-side where your framework requires a client boundary for React hooks and browser APIs.
