SingleRange creates a numeric range selector UI component that is connected to a database field.

Note

It is similar to a SingleList, except it is suited for numeric data.

Example uses:

• filtering search results by prices in an e-commerce or food delivery experience.
• browsing a movies listing site using a ratings filter.

<template>
	<single-range
		title="Prices"
		componentId="PriceSensor"
		dataField="price"
		:data="
            [{'start': 0, 'end': 10, 'label': 'Cheap'},
            {'start': 11, 'end': 20, 'label': 'Moderate'},
            {'start': 21, 'end': 50, 'label': 'Pricey'},
            {'start': 51, 'end': 1000, 'label': 'First Date'}]
        "
	/>
</template>

<template>
	<single-range
		componentId="PriceSensor"
		compoundClause="filter"
		dataField="price"
		title="Prices"
		defaultValue="Cheap"
		filterLabel="Price"
		:data="
			[{'start': 0, 'end': 10, 'label': 'Cheap'},
			 {'start': 11, 'end': 20, 'label': 'Moderate'},
			 {'start': 21, 'end': 50, 'label': 'Pricey'},
			 {'start': 51, 'end': 1000, 'label': 'First Date'}]
		"
		:showRadio="true"
		:showFilter="true"
		:URLParams="false"
		:endpoint="{
			url:'https://appbase-demo-ansible-abxiydt-arc.searchbase.io/recipes-demo/_reactivesearch.v3',
			headers: {
				// put relevant headers
			},
			method: 'POST'
		}"		
	/>
</template>

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

Configure whether the DSL query is generated with the compound clause of must or filter. If nothing is passed the default is to use must. Setting the compound clause to filter allows search engine to cache and allows for higher throughput in cases where scoring isn’t relevant (e.g. term, geo or range type of queries that act as filters on the data)

This property only has an effect when the search engine is either elasticsearch or opensearch.

Note: compoundClause is supported with v8.16.0 (server) as well as with serverless search.

endpoint prop provides the ability to query a user-defined backend service for this component, overriding the data endpoint configured in the ReactiveBase component. 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.

data field to be connected to the component's UI view. The range items are filtered by a database query on this field.

collection of UI labels with associated start and end range values.

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 of the component to be shown in the UI.

pre-select a label from the data array.

sets the current value of the component. It sets the value (on mount and on update). Use this prop in conjunction with the change event.

show radio button icon for each range item. Defaults to true.

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

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.

enable creating a URL query string parameter based on the selected value of the range. This is useful for sharing URLs with the component state. Defaults to false.

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.

SingleRange component supports innerClass prop with the following keys:

• title
• list
• radio
• label

Read more about it here.

SingleRange 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, value-change and query-change.

<template>
	<single-range
		className="custom-class"
		:customQuery="getCustomQuery"
		:react="react"
		:beforeValueChange="handleBeforeValueChange"
		@value-change="handleValueChange"
		@query-change="handleQueryChange"
	/>
</template>
<script>
	export default {
		name: 'app',
		methods: {
			getCustomQuery: (value, props) => {
				return {
					query: {
						match: {
							data_field: 'this is a test',
						},
					},
				};
			},
			handleBeforeValueChange: value => {
				
				
				return new Promise((resolve, reject) => {
					
					resolve();
					
				});
			},
			handleValueChange: value => {
				console.log('current value: ', value);
				
				
			},
			handleQueryChange: (prevQuery, nextQuery) => {
				
				console.log('prevQuery', prevQuery);
				console.log('nextQuery', nextQuery);
			},
		},
		computed: {
			react() {
				return {
					and: ['pricingFilter', 'dateFilter'],
					or: ['searchFilter'],
				};
			},
		},
	};
</script>

CSS class to be injected on the component container.

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

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 >= 1.1.0, 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 => {
	
	if (value.start < 4) {
		
		throw Error('Rating must be greater than or equal to 4.');
	}
};

is an event that 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 event is useful to control the value updates of search input.

<template>
	<single-range
		// ...other props
		value="value"
		@change="handleChange"
	/>
</template>

<script>
export default {
name: 'app',
	data() {
		return {
			value: ""
		}
	},
	methods: {
		handleChange(value) {
			this.value = value;
		}
	}
};
</script>

is an event which accepts component's prevQuery and nextQuery as parameters. It is called everytime the component's query changes. This event is handy in cases where you want to generate a side-effect whenever the component's query would change.

is an event which accepts component's current value as a parameter. It is called everytime the component's value changes. This event 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 range item(s) is/are selected in a "Discounted Price" SingleRange.
