Usage

usage.tsx
import CounterAnimation from "@/components/counter-animation/counter-animation";export default function Example() {  return <CounterAnimation number={60} className="text-2xl font-semibold" />;}
  • Highlight key metrics such as users, sales, downloads, or completed tasks.
  • Add visual emphasis to dashboard statistics and analytics cards.
  • Use for landing-page proof points where animated numerical feedback attracts attention.
  • Pair with external typography and layout classes to match the surrounding design system.

Examples

Percentage metric

Displays a percentage value with a suffix.

percentage-metric.tsx
import CounterAnimation from "@/components/counter-animation/counter-animation";export default function ConversionRate() {  return <CounterAnimation number={87} suffix="%" className="text-4xl font-bold" />;}

Revenue metric

Displays a currency prefix before the animated number.

revenue-metric.tsx
import CounterAnimation from "@/components/counter-animation/counter-animation";export default function Revenue() {  return <CounterAnimation number={12500} prefix="$" className="text-3xl font-semibold" />;}

Labeled count

Combines a numeric value with a suffix label.

labeled-count.tsx

API reference

PropTypeDefaultDescription
numbernumber—Required target number for the animation. The counter starts at 0 and animates to this value over two seconds, displaying rounded integer values.
classNamestring | undefined—Optional CSS class name applied to the root span through the cn utility.
prefixstring | undefined—Optional string rendered immediately before the current number.
suffixstring | undefined—Optional string rendered immediately after the current number.

Accessibility

  • The component renders a span with no built-in semantic role or accessible label.
  • Provide surrounding text or an appropriate accessible context when the number's meaning is not clear from nearby content.
  • Do not rely on the animation alone to communicate the value; ensure the final number remains understandable when motion is reduced or unavailable.
  • Avoid using rapidly changing counters as the only way to communicate important information to assistive-technology users.
