The official React UI Bindings layer for Search Headless
Search Headless React is the official React UI Bindings layer for Search Headless.
Written in 100% TypeScript.
npm install @yext/search-headless-react
SearchHeadlessProvider
Search Headless React includes an <SearchHeadlessProvider />
component, which takes in a SearchHeadless
instance and makes it available to the rest of your app. SearchHeadless
instance is created using provideHeadless(...)
with the appropriate credentials:
import { provideHeadless, SearchHeadlessProvider } from '@yext/search-headless-react';
import SearchBar from './SearchBar';
import MostRecentSearch from './MostRecentSearch';
import UniversalResults from './UniversalResults';
const searcher = provideHeadless(config);
function MyApp() {
return (
<SearchHeadlessProvider searcher={searcher}>
{/* Add components that use Search as children */}
<SearchBar/>
<MostRecentSearch/>
<UniversalResults/>
</SearchHeadlessProvider>
);
}
useSearchState
useSearchState
reads a value from the SearchHeadless
state and subscribes to updates.
import { useSearchState } from '@yext/search-headless-react';
export default function MostRecentSearch() {
const mostRecentSearch = useSearchState(state => state.query.mostRecentSearch);
return <div>Showing results for {mostRecentSearch}</div>;
}
useSearchActions
useSearchActions
allows you to dispatch actions using the SearchHeadless
instance.
These include performing searches, getting autocomplete suggestions, and adding filters.
For a full list of capabilities see the search-headless docs.
import { useSearchActions } from '@yext/search-headless-react';
import { ChangeEvent, KeyboardEvent, useCallback } from 'react';
function SearchBar() {
const search = useSearchActions();
const handleTyping = useCallback((e: ChangeEvent<HTMLInputElement>) => {
search.setQuery(e.target.value);
}, [search]);
const handleKeyDown = useCallback((evt: KeyboardEvent<HTMLInputElement>) => {
if (evt.key === 'Enter' ) {
search.executeUniversalQuery();
}
}, [search]);
return <input onChange={handleTyping} onKeyDown={handleKeyDown}/>;
}
SearchHeadlessContext
For users that want to use class components instead of functional components, you can use the SearchHeadlessContext
directly to dispatch actions and receive updates from state.
As an example, here is our simple SearchBar again, rewritten as a class using SearchHeadlessContext
.
import { SearchHeadlessContext, SearchHeadless, State } from '@yext/search-headless-react';
import { Component } from 'react';
export default class Searcher extends Component {
static contextType = SearchHeadlessContext;
unsubscribeQueryListener: any;
state = { query: "" };
componentDidMount() {
const search: SearchHeadless = this.context;
this.unsubscribeQueryListener = search.addListener({
valueAccessor: (state: State) => state.query.mostRecentSearch,
callback: newPropsFromState => {
this.setState({ query: newPropsFromState })
}
});
}
componentWillUnmount() {
this.unsubscribeQueryListener();
}
render() {
const search: SearchHeadless = this.context;
return (
<div>
<p>Query: {this.state.query}</p>
<input
onChange={evt => search.setQuery(evt.target.value)}
onKeyDown={evt => {
if (evt.key === 'Enter') {
search.executeUniversalQuery();
}
}}
/>
</div>
)
}
}
useSearchUtilities
We offer a useSearchUtilities
convenience hook for accessing SearchHeadless.utilities
, which offers a number of stateless utility methods.
The searchUtilities
and searchUtilitiesFromActions
variables below are equivalent.
For class components, you can access SearchUtilities
through SearchHeadlessContext
.
const searchUtilities = useSearchUtilities();
const searchUtilitiesFromActions = useSearchActions().utilities;
