``bash`
$ npm i --save react-rangeror
$ yarn add react-ranger
The following is a very basic example of a single range input that looks similar to Chrome's default appearance.
`javascript
import ReactRanger from 'react-ranger'
function App() {
const [values, setValues] = React.useState([10])
const { getTrackProps, handles } = useRanger({
values,
onChange: setValues,
min: 0,
max: 100,
stepSize: 5,
})
return (
<>
Options
-
value: Array - The current value (or values) for the range
- Required
- min: number - The minimum limit for the range
- Required
- max: number - The maximum limit for the range
- Required
- stepSize: number - The distance between selectable steps
- Required
- steps: arrayOf(number) - An array of custom steps to use. This will override stepSize,
- tickSize: number
- ticks: arrayOf(number): Default: 10 - An array of custom ticks to use. This will override tickSize,
- onChange: Function(newValue) - A function that is called when the handle is released
- onDrag: Function(newValue) - A function that is called when a handled is dragged
- interpolator: { getPercentageForValue: Function(value) => decimal, getValueForClientX: Function(x) => value}
- The Interpolator to use
- Defualts to the bundled linear-scale interpolator
See the Interpolation section for more infoReturns
useRanger returns an object with the following properties:-
getTrackProps(userProps): func - A function that takes optional props and returns the combined necessary props for the track component.
- ticks: array - Ticks to be rendered. Each tick has the following props:
- value: number - The tick number to be displayed
- getTickProps(userProps): func - A function that take optional props and returns the combined necessary props for the tick component.
- segments: array - Segments to be rendered. Each segment has the following props:
- value: number - The segments ending value
- getSegmentProps(userProps): func - A function that take optional props and returns the combined necessary props for the segment component.
- handles: array - Handles to be rendered. Each handle has the following props:
- value: number - The current value for the handle
- active: boolean - Denotes if the handle is currently being dragged.
- getHandleProps(userProps): func - A function that take optional props and returns the combined necessary props for the handle component.
- activeHandleIndex: oneOfType([null, number]) - The zero-based index of the handle that is currently being dragged, or null if no handle is being dragged.Interpolation
By default,
react-ranger uses linear interpolation between data points, but allows you to easily customize it to use your own interpolation functions by passing an object that implements the following interface:`
const interpolator = {
// Takes the value & range and returns a percentage [0, 100] where the value sits from left to right
getPercentageForValue: (val: number, min: number, max: number): number // Takes the clientX (offset from the left edge of the ranger) along with the dimensions
// and range settings and transforms a pixel coordinate back into a value
getValueForClientX: (clientX: number, trackDims: object, min: number, max: number): number
}
`Here is an exmaple of building and using a logarithmic interpolator!
`javascript
import { useRanger } from 'react-ranger'const logInterpolator = {
getPercentageForValue: (val, min, max) => {
const minSign = Math.sign(min)
const maxSign = Math.sign(max)
if (minSign !== maxSign) {
throw new Error(
'Error: logarithmic interpolation does not support ranges that cross 0.'
)
}
let percent =
(100 / (Math.log10(Math.abs(max)) - Math.log10(Math.abs(min)))) *
(Math.log10(Math.abs(val)) - Math.log10(Math.abs(min)))
if (minSign < 0) {
// negative range, means we need to invert our percent because of the Math.abs above
return 100 - percent
}
return percent
},
getValueForClientX: (clientX, trackDims, min, max) => {
const { left, width } = trackDims
let value = clientX - left
value *= Math.log10(max) - Math.log10(min)
value /= width
value = Math.pow(10, Math.log10(min) + value)
return value
},
}
useRanger({
interpolator: logInterpolator,
})
