DynamicRangeSlider

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 ..."
    includeNullValues
    endpoint={{
      url:"https://appbase-demo-ansible-abxiydt-arc.searchbase.io/recipes-demo/_reactivesearch.v3", //mandatory
      headers:{
        // relevant headers
      },
      method: 'POST'
    }}         
/>

Props

componentId

unique identifier of the component, can be referenced in other components' react prop.

endpoint

• url String [Required] URL where the data cluster is hosted.
• headers Object [optional]
  set custom headers to be sent with each server request as key/value pairs.
• method String [optional]
  set method of the API request.
• body Object [optional]
  request body of the API request. When body isn't set and method is POST, the request body is set based on the component's configured props.

• Overrides the endpoint property defined in ReactiveBase.
• If required, use transformResponse prop to transform response in component-consumable format.

dataField

DB data field to be mapped with the component's UI view.The selected range creates a database query on this field.

nestedField

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

title of the component to be shown in the UI.

defaultValue

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

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

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

a function that accepts min and max range values as parameters and returns an object representing labels with start and end keys.

showFilter

show the selected item as a filter in the selected filters view. Defaults to true.

snap

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

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

trigger the tooltip according to the value specified. Can be hover, focus, always and none. Defaults to none.

renderTooltipData

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

whether to display the range histogram or not. Defaults to true.

interval

set the histogram bar interval, applicable when showHistogram is true. Defaults to Math.ceil((props.range.end - props.range.start) / 100) || 1.

loader

to display an optional loader while fetching the histogram stats.

URLParams

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.

includeNullValues

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

Set the date format to be used for querying data, default value is set to date. It can accept one of the following values:

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

calendarInterval

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

DynamicRangeSlider 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.

<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

CSS class to be injected on the component container.

style

CSS styles to be applied to the DynamicRangeSlider component.

customQuery

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

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:

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

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

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

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.

index

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.
