ToggleButton creates a toggle button UI component that is connected to a database field. It is used for filtering results based on a fixed set of toggle-able options.

Example uses:

  • filter movies by ratings between 1 and 5,
  • display restaurants that accept delivery and are open now,
  • show flight tickets by one way, round trip and multi-city options.

Props

componentId

Type Optional
String No

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

endpoint

Type Optional
Object Yes

endpoint prop provides the ability to query a user-defined backend service for this component, overriding the data endpoint configured in the ReactiveBase component. Works only when enableAppbase is true. Accepts the following properties:

  • 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

Type Optional
String No

data field to be connected to the component's UI view.

data

Type Optional
Object Array Yes

collection of UI labels with associated value to be matched against the database field.

nestedField

Type Optional
String Yes

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

Type Optional
String Yes

or JSX [optional] title of the component to be shown in the UI.

defaultValue

Type Optional
String Yes

or Array [optional] an array of default selected label(s) to pre-select one or more buttons.

value

Type Optional
String Array Yes

controls the current value of the component. It selects the label (on mount and on update). Use this prop in conjunction with onChange function.

multiSelect

Type Optional
Boolean Yes

whether multiple buttons can be selected, defaults to true. When set to false, only one button can be selected.

showFilter

Type Optional
Boolean Yes

show as filter when a value is selected in a global selected filters view. Defaults to true.

filterLabel

Type Optional
String Yes

An optional label to display for the component in the global selected filters view. This is only applicable if showFilter is enabled. Default value used here is componentId.

URLParams

Type Optional
Boolean Yes

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.

onChange

Type Optional
function Yes

is a callback function which accepts component's current value as a parameter. It is called when you are using the value props and the component's value changes. This prop is used to implement the controlled component behavior.

enableStrictSelection

Type Optional
Boolean Yes

When set to true, a selected option can't be unselected. Although, it is possible to change the selected option. Defaults to false.

Copy
> Note: This only works when `multiSelect` prop is set to `false`.

Extending

ToggleButton 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.
Copy
<ToggleButton
  ...
  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);
    }
  }
/>

className

Type Optional
String Yes

CSS class to be injected on the component container.

style

Type Optional
Object Yes

CSS styles to be applied to the ToggleButton component.

customQuery

Type Optional
Function Yes

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 ToggleButton component as long as the component is a part of react dependency of at least one other component.

beforeValueChange

Type Optional
Function Yes

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 = values => {
   // The update is accepted by default
   if (values.includes('Social')) {
   	// To reject the update, throw an error
   	throw Error('Selected value should not include Social.');
   }
};

onValueChange

Type Optional
Function Yes

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(s) when button(s) is/are selected in a "Discounted Price" ToggleButton.

onQueryChange

Type Optional
Function Yes

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.

index

Type Optional
String Yes

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.
