DynamicRangeSlider

Image to be displayed

DynamicRangeSlider creates a numeric range slider UI component. It is used for granular filtering of numeric data.

Example uses:

filtering products from a price range in an e-commerce shopping experience.
filtering flights from a range of departure and arrival times.

Note

This component behaves similar to the RangeSlider except that the range is computed dynamically based on actual data.

Usage

Basic Usage

<DynamicRangeSlider
  componentId="DynamicRangeSensor"
  dataField="guests"
/>

While DynamicRangeSlider only requires the above props to be used, it comes with many additional props for pre-selecting range values, setting the step value of the range slider, specifying labels for the range endpoints, whether to display histogram etc.

Usage With All Props

<DynamicRangeSlider
  componentId="DynamicRangeSensor"
  dataField="guests"
  title="Guests"
  defaultValue={(min, max) => (
    {
      "start": min,
      "end": Math.min(min + 5, max)
    }
  )}
  rangeLabels={(min, max) => (
    {
      "start": min + " guest",
      "end": max + " guests"
    }
  )}
  stepValue={1}
  showHistogram={true}
  showFilter={true}
  interval={2}
  react={{
    and: ["CategoryFilter", "SearchFilter"]
  }}
  URLParams={true}
  loader="Loading ..."
/>

Props

componentId String unique identifier of the component, can be referenced in other components’ react prop.
dataField String DB data field to be mapped with the component’s UI view.The selected range creates a database query on this field.
nestedField String [optional] use to set the nested mapping field that allows arrays of objects to be indexed in a way that they can be queried independently of each other. Applicable only when dataField is a part of nested type.
title String or JSX [optional] title of the component to be shown in the UI.
defaultValue Function [optional] a function that accepts min and max range values as parameters and returns an object representing current selection from the range with start and end keys.
value Object [optional] controls the current value of the component.It selects the item from the dynamic range (on mount and on update).Use this prop in conjunction with onChange function.
onChange function [optional] is a callback function which accepts component’s current value as a parameter. It is called when you are using the value prop and the component’s value changes. This prop is used to implement the controlled component behavior.
rangeLabels Function [optional] a function that accepts min and max range values as parameters and returns an object representing labels with start and end keys.
showFilter Boolean [optional] show the selected item as a filter in the selected filters view. Defaults to true.
snap Boolean [optional] makes the slider snap on to points depending on the stepValue when the slider is released. Defaults to true. When set to false, stepValue is ignored.
stepValue Number [optional] step value specifies the slider stepper. Value should be an integer greater than or equal to 1 and less than Math.floor((range.end - range.start) / 2). Defaults to 1.
tooltipTrigger String [optional] trigger the tooltip according to the value specified. Can be hover, focus, always and none. Defaults to none.

renderTooltipData Function [optional] customize the rendered tooltip content via a function which receives the tooltip content and expects a JSX or String back. For example:

renderTooltipData={data => (
    <h5 style={{
        color: 'red',
        textDecoration: 'underline'
    }}>
        {data}
    </h5>
)}

showHistogram Boolean [optional] whether to display the range histogram or not. Defaults to true.
interval Number [optional] set the histogram bar interval, applicable when showHistogram is true. Defaults to Math.ceil((props.range.end - props.range.start) / 100) || 1.
loader String or JSX [optional] to display an optional loader while fetching the histogram stats.
URLParams Boolean [optional] enable creating a URL query string parameter based on the selected range of the slider. This is useful for sharing URLs with the component state. Defaults to false.

Styles

DynamicRangeSlider component supports innerClass prop with the following keys:

title
slider
label

Extending

DynamicRangeSlider component can be extended to

customize the look and feel with className, style.
update the underlying DB query with customQuery.
connect with external interfaces using beforeValueChange, onValueChange and onQueryChange,
filter data using a combined query context via the react prop.

<DynamicRangeSlider
  ...
  className="custom-class"
  style={{"paddingBottom": "10px"}}
  customQuery={
    function(value, props) {
      return {
        query: {
            match: {
                data_field: "this is a test"
            }
        }
      }
    }
  }
  onValueChange={
    function(value) {
      console.log("current value: ", value)
      // set the state
      // use the value with other js code
    }
  }
  onQueryChange={
    function(prevQuery, nextQuery) {
      // use the query with other js code
      console.log('prevQuery', prevQuery);
      console.log('nextQuery', nextQuery);
    }
  }
  beforeValueChange={
    function(value) {
      // called before the value is set
      // returns a promise
      return new Promise((resolve, reject) => {
        // update state or component props
        resolve()
        // or reject()
      })
    }
  }
  react={{
    "and": ["ListSensor"]
  }}
/>

className String CSS class to be injected on the component container.
style Object CSS styles to be applied to the DynamicRangeSlider component.
customQuery Function takes value and props as parameters and returns the data query to be applied to the component, as defined in Elasticsearch Query DSL. Note: customQuery is called on value changes in the DynamicRangeSlider component as long as the component is a part of react dependency of at least one other component.
beforeValueChange Function is a callback function which accepts component’s future value as a parameter and returns a promise. It is called everytime before a component’s value changes. The promise, if and when resolved, triggers the execution of the component’s query and if rejected, kills the query execution. This method can act as a gatekeeper for query execution, since it only executes the query after the provided promise has been resolved.
onValueChange Function is a callback function which accepts component’s current value as a parameter. It is called everytime the component’s value changes. This prop is handy in cases where you want to generate a side-effect on value selection. For example: You want to show a pop-up modal with the valid discount coupon code when a user selects a particular range in a DynamicRangeSlider.
onQueryChange Function is a callback function which accepts component’s prevQuery and nextQuery as parameters. It is called everytime the component’s query changes. This prop is handy in cases where you want to generate a side-effect whenever the component’s query would change.
react Object specify dependent components to reactively update DynamicRangeSlider’s data view.
- key String one of and, or, not defines the combining clause.
  - and clause implies that the results will be filtered by matches from all of the associated component states.
  - or clause implies that the results will be filtered by matches from at least one of the associated component states.
  - not clause implies that the results will be filtered by an inverse match of the associated component states.
- value String or Array or Object
  - String is used for specifying a single component by its componentId.
  - Array is used for specifying multiple components by their componentId.
  - Object is used for nesting other key clauses.
