Props

  • componentId String unique identifier of the component, can be referenced in other components’ react prop.
  • dataField String data field to be mapped with the component’s UI view.
  • data Object Array collection of UI label with associated with start and end ratings values.
  • 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.
  • icon JSX [optional] to render custom active icon.
  • dimmedIcon JSX [optional] to render custom inactive icon.
  • defaultValue Object [optional] selects a initial ratings value 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 item from the data (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.
  • URLParams Boolean [optional] enable creating a URL query string parameter based on the selected rating. This is useful for sharing URLs with the component state. Defaults to false.

Extending

RatingsFilter 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.
<RatingsFilter
  ...
  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()
      })
    }
  }
  onQueryChange={
    function(prevQuery, nextQuery) {
      // use the query with other js code
      console.log('prevQuery', prevQuery);
      console.log('nextQuery', nextQuery);
    }
  }
  onValueChange={
    function(value) {
      console.log("current value: ", value)
      // set the state
      // use the value with other js code
    }
  }
/>
  • className String CSS class to be injected on the component container.
  • style Object CSS styles to be applied to the RatingsFilter 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 RangeFilter 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 searches for a product with a specific rating in a RatingsFilter.
  • 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.
