Props

The algorithm, by default linear, the slider will use. Feel free to write your own as long as it conforms to the shape.

  algorithm: PropTypes.shape({
    getValue: PropTypes.func,
    getPosition: PropTypes.func,
  })

Custom class name that will be applied to the root of Rheostat.

  className: PropTypes.string

  handle: PropTypes.oneOfType([PropTypes.func, PropTypes.string])
  progressBar: PropTypes.oneOfType([PropTypes.func, PropTypes.string])

The maximum and minimum possible values, by default 0 - 100.

  max: PropTypes.number
  min: PropTypes.number

pitComponent is a custom React component for rendering "pits" across the bar. pitPoints is the set of points at which it will render a pit. Points are an array of values on the slider.

  pitComponent: PropTypes.oneOfType([PropTypes.func, PropTypes.string])
  pitPoints: PropTypes.arrayOf(PropTypes.number)

NOTE: onChange is called whenever the value is changed and committed. This happens at the end of a drag, keypress, or click event. onChange is recommended when you wish to persist the values.

onValuesUpdated is a convenience event that is triggered while the value is being actively changed. This includes dragging, click, or keypress. onValuesUpdated is recommended if you need to work with the values before they're committed.

  onChange: PropTypes.func
  onClick: PropTypes.func
  onKeyPress: PropTypes.func
  onSliderDragEnd: PropTypes.func
  onSliderDragMove: PropTypes.func
  onSliderDragStart: PropTypes.func
  onValuesUpdated: PropTypes.func

snap is a boolean which controls the slider's snapping behavior. snapPoints is an array of values on the slider where the slider should snap to.

If snap is set to true and no snapPoints are set then the slider is snapped into an absolute position. For example, on a scale of 1-10 if the slider is let go at the 54% mark it'll pick the value 5 and snap to 50%.

  snap: PropTypes.bool
  snapPoints: PropTypes.arrayOf(PropTypes.number)

The values, by default 0 and 100.

  values: PropTypes.arrayOf(PropTypes.number)

You can disable the slider to prevent the user from moving it.

  disabled: PropTypes.bool
