⚙️ Configuration

NumericStepper supports the following props:

Prop Type Default value Description
minimumValue number 0 The minimum value.
maximumValue number Number.MAX_SAFE_INTEGER The maximum value.
stepValue number 1 The step increment value.
initialValue number minimumValue The initial value.
onChange Function undefined The callback invoked when the value changes.
size string sm The size of the numeric stepper. There are 3 available sizes:

  • sm — 185x74px
  • md — 277.5x111px
  • lg — 370x148px
inactiveTrackColor string #2b2b2b The color of the track while the thumb is not being horizontally dragged.
activeTrackColor string #1f1f1f The color of the track while the thumb is being horizontally dragged and is at the maximum trackable distance from the track’s center.
hoverButtonColor string transparent The color of the decrement/increment button in a hover state.
activeButtonColor string #ececec The color of the decrement/increment button in an active state.
inactiveIconColor string #858585 The color of the decrement/increment button icon in an inactive state.
hoverIconColor string #ffffff The color of the decrement/increment button icon in a hover state.
activeIconColor string #000000 The color of the decrement/increment button icon in an active state.
disabledIconColor string #383838 The color of the decrement/increment button icon in a disabled state.
thumbColor string #444444 The color of the thumb.
thumbLabelColor string #ffffff The color of the thumb’s label.
thumbShadowAnimationOnTrackHoverEnabled boolean true If true, the thumb’s shadow will animate when hovering over the track.
focusRingColor string #ececec The color of the focus ring of the interactive elements.

In order to customise the thumb’s font settings, we can use CSS, like so:

[data-testid='numeric-stepper-thumb'] {
  font-family: 'Times New Roman', Times, serif;
  font-style: italic;
  font-weight: 800;
}

♿️ Accessibility

In order to comply with the web accessibility standards, we must make use of the decrementButtonAriaLabel and incrementButtonAriaLabel props, like so:

function AccessibleExample() {
  return (
    <NumericStepper
      decrementButtonAriaLabel="Decrement"
      incrementButtonAriaLabel="Increment"
    />
  );
}

Also, we can use a thumbAriaLabel prop to provide a description for the value rendered inside a thumb, like so:

function EnhancedThumbAccessibilityExample() {
  const [value, setValue] = useState(0);
  return (
    <NumericStepper
      thumbAriaLabel={`${value} items`}
      onChange={(value) => {
        setValue(value);
      }}
    />
  );
}
