Guide > Connectors

React InstantSearch provides widgets out of the box, those are great when you want a default style to be applied and you do not need heavy customization of the underlying DOM or behavior of the widget.

When do I need to use connectors?

  • When you want to display our widgets using another UI library like Material-UI
  • When you want to have full control on the rendering without having to reimplement business logic
  • As soon as you hit a feature wall using our default widgets
  • When you are a react-native user, read our react-native guide

What are 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.

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

How to use them?

If you want to create your own search box, you will need to use the connectSearchBox() connector:

import {connectSearchBox} from 'react-instantsearch/connectors'; const MySearchBox = ({currentRefinement, refine}) => <input type="text" value={currentRefinement} onChange={e => refine(} />; // `ConnectedSearchBox` renders a `<MySearchBox>` widget that is connected to // the <InstantSearch> state, providing it with `currentRefinement` and `refine` props for // reading and manipulating the current query of the search. // Note that this `ConnectedSearchBox` widget will only work when rendered // as a child or a descendant of the `<InstantSearch>` component. const ConnectedSearchBox = connectSearchBox(MySearchBox);

Exposed props

Connectors expose props to configure their behavior. Like the attributeName being refined in a <Menu>.

One common exposed prop that you can use is the defaultRefinement one. Use it when as a way to provide the default refinement when the connected component will be mounted.

Provided props

Provided props always follow the same pattern for ease of use:

  • currentRefinement: Search state representation of the connector, most of the time you do not need that
  • refine: Function to call to refine the search state of the connector
  • createURL: See the routing guide
  • items[{label, value, count}]: Only when dealing with list based connectors
    • label: Text representation of the item to be shown
    • value: State representation to be used when calling refine() or createURL()
    • count: Number of hits concerned by the facet
    • isRefined: Indicates if the item is currently selected refining the search state
