RangeSlider 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.

Usage

Basic Usage

Copy 
<RangeSlider
	componentId="RangeSliderSensor"
	dataField="guests"
	title="Guests"
	range={{
		start: 0,
		end: 10,
	}}
/>

While RangeSlider only requires the above props to be used, it comes with many additional props for pre-setting default 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

Copy 
<RangeSlider
	componentId="RangeSliderSensor"
	dataField="guests"
	title="Guests"
	range={{
		start: 0,
		end: 10,
	}}
	defaultValue={{
		start: 1,
		end: 5,
	}}
	rangeLabels={{
		start: 'Start',
		end: 'End',
	}}
	stepValue={1}
	showHistogram={true}
	showFilter={true}
	interval={2}
	react={{
		and: ['CategoryFilter', 'SearchFilter'],
	}}
	URLParams={false}
	includeNullValues
/>

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.

  • range Object an object with start and end keys and corresponding numeric values denoting the minimum and maximum possible slider values.

    range prop accepts Date objects as values corresponding to start and end keys when date-types are dealt with.

    Copy 
        <RangeSlider
        componentId="RangeSliderSensor"
        dataField="timestamp"
        title="Publication Year"
        range={{
            start: new Date('1980-12-12'),
            end: new Date('2000-12-12'),
        }}
        queryFormat="date"            
    />

  • 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 Object [optional] selects a initial range values using start and end key values from one of the data elements.

  • value Object [optional] controls the current value of the component. It selects the data from the 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 Object [optional] an object with start and end keys and corresponding String labels to show labels near the ends of the RangeSlider component.

  • 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:

    Copy 
    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.

  • URLParams Boolean [optional] enable creating a URL query string parameter based on the selected value of the list. This is useful for sharing URLs with the component state. Defaults to false.

  • includeNullValues Boolean [optional] If you have sparse data or document or items not having the value in the specified field or mapping, then this prop enables you to show that data. Defaults to false.

  • queryFormat String Pass the queryFormat prop when dealing with date-type fields. Defaults to date. It sets the date format to be used in the query, can accept one of the following:


queryFormat

Representation as elasticsearch date
epoch_millis (default) epoch_millis
epoch_second epoch_second
basic_time HHmmss.SSSZ
basic_time_no_millis HHmmssZ
date yyyy-MM-dd
basic_date yyyyMMdd
basic_date_time yyyyMMdd'T'HHmmss.SSSZ
basic_date_time_no_millis yyyyMMdd'T'HHmmssZ
date_time_no_millis yyyy-MM-dd'T'HH:mm:ssZZ

Note: queryFormat is mandatory to pass when dealing with date types.

  • calendarInterval String [optional] It sets the interval for aggreation-data when dealing with date-types. Default value is calculated internally based on the range - start and end values. It can accept one of the following: year, quarter, month, week, day, hour, and minute.

Extending

RangeSlider component can be extended to

  1. customize the look and feel with className, style,
  2. update the underlying DB query with customQuery,
  3. connect with external interfaces using beforeValueChange, onValueChange and onQueryChange,
  4. filter data using a combined query context via the react prop.
Copy 
<RangeSlider
  ...
  className="custom-class"
  style={{"paddingBottom": "10px"}}
  customQuery={
    function(value, props) {
      return {
        query: {
            match: {
                data_field: "this is a test"
            }
        }
      }
    }
  }
  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()
      })
    }
  }
  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);
    }
  }
  react={{
    "and": ["ListSensor"]
  }}
/>

  • className String CSS class to be injected on the component container.

  • style Object CSS styles to be applied to the RangeSlider 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 RangeSlider 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.

    Note:

    If you're using Reactivesearch version >= 3.3.7, beforeValueChange can also be defined as a synchronous function. value is updated by default, unless you throw an Error to reject the update. For example:

    Copy 
    beforeValueChange = value => {
    // The update is accepted by default
	if (value.start > 3000) {
		// To reject the update, throw an error
		throw Error('Start value must be less than or equal to 3000.');
	}
};

  • 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 some range is selected in a "Discounted Price" RangeSlider.

  • 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 RangeSlider'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.

  • index String [optional] The index prop can be used to explicitly specify an index to query against for this component. It is suitable for use-cases where you want to fetch results from more than one index in a single ReactiveSearch API request. The default value for the index is set to the app prop defined in the ReactiveBase component.

    Note: This only works when enableAppbase prop is set to true in ReactiveBase.
