Measured entry

magicui-number-ticker

text-effectunclassifiedmotion on file

A client-side React span that spring-animates from a starting value to a target when it enters the viewport. It ships as a shadcn registry component, uses Motion for animation, formats output with Intl.NumberFormat, and relies on a cn utility backed by clsx and tailwind-merge plus Tailwind classes.

Verdict

A focused, working ticker with clean viewport-triggered behavior and no provider requirement. The configured harness passed, but the bare check timed out and did not mount, so it needs a shadcn-style setup or equivalent project wiring before adoption.

Use it if

  • You need a one-time count-up or count-down effect for a dashboard metric, price, or milestone.
  • Your React app already uses Tailwind and a shadcn-style cn helper.
  • US-style number formatting and fixed decimal-place control fit the display requirement.

Skip it if

  • You need locale-aware formatting chosen from the viewer or application settings.
  • The value must update continuously after the first in-view animation.
  • You want a dependency-free text effect or cannot justify adding Motion for one counter.
  • Your project does not support client components or browser viewport observation.

In a non-shadcn project, add Motion, clsx, and tailwind-merge; provide a compatible cn helper and configure the source alias it imports. Ensure Tailwind processes the component classes, and place it in a React environment that supports client components.
