Info

What it is

Show off a big number the satisfying way: digits roll like a car's odometer from a starting value to your target, slowing down as they arrive. Add a prefix like $ or a suffix like + or 'users', choose the colour and how long it counts. Great for milestones, stats and results.

Reuse it in your own idea

  • Combine with Soft Moving Gradient and a spring pop-in label (see Minimal Animated Number Reveal).
  • Use valueAt(t) alone to drive a progress bar or a 3D bar chart.
  • Place several counters (x/y options) for a stats grid.

Which part is reusable

src/rolling-counter.js is the ingredient your AI reuses. demo.js is only the example scene around it, and uses the demo harness only for the demo.

See it combined with other ingredients in Minimal Animated Number Reveal.

Good to know

  • Whole numbers only (no decimals).

Implementation
Canvas 2D — plain browser JavaScript, no libraries · ES module src/rolling-counter.js
Exports
  • createRollingCounter({ from?, to?, delay?, duration?, ease?, prefix?, suffix?, separator?, color?, fontFamily?, weight?, size?, x?, y?, align? }) => { draw(ctx, info, width, height), valueAt(t) }
Dependencies (exact)
  • apw-runtime@1.0.0 (demo) — Demo harness. src/rolling-counter.js has no dependencies.
How it fits a scene

Coordinates: Centre point as fractions of width/height; size as a fraction of the shorter side.

Lighting: None.

Timing: Pure function of time; valueAt(t) gives the exact value at any moment.
