Customize the UI - connectRange

If you want to create your own UI of the RangeInput widget or use another UI library, you can use connectors.

Connectors are higher-order components. They encapsulate the logic for a specific kind of widget and they provide a way to interact with the InstantSearch context.

They have an outer component API that we call exposed props, and they provide some other props to the wrapped components which are called the provided props.

This connector is also used to build other widgets: RangeSlider RatingMenu

It’s a 3-step process:

// 1. Create a React component
const RangeInput = () => {
  // return the DOM output
};

// 2. Connect the component using the connector
const CustomRangeInput = connectRange(RangeInput);

// 3. Use your connected widget
<CustomRangeInput />

Create a React component

const RangeInput = ({
  object currentRefinement,
  number min,
  number max,
  number precision,
  function refine,
  __function_ createURL,
}) => {
  // return the DOM output
};

Provided Props

currentRefinement
type: object

The currently applied refinement or the minimum/maximum value.
