Installation

Installing React InstantSearch

React InstantSearch can be used either with a packaging system or with a direct link in your webpage.

With a build system

If you have a JavaScript build system, you can install React InstantSearch from npm:

1
npm install algoliasearch react-instantsearch-dom

Then in your module, you can load the main package:

1

import algoliasearch from 'algoliasearch/lite';
import { InstantSearch, SearchBox, Hits } from 'react-instantsearch-dom';

const searchClient = algoliasearch('YourApplicationID', 'YourSearchOnlyAPIKey');

const App = () => (
  <InstantSearch searchClient={searchClient} indexName="demo_ecommerce">
    <SearchBox />
    <Hits />
  </InstantSearch>
);

The code examples on this page use the algoliasearch/lite client, which does not provide indexing methods. If you want to perform indexing operations, you have to import the regular algoliasearch client.

Directly in your page

This method uses a built version of React InstantSearch from the jsDelivr CDN:

The jsDeliver CDN is highly available with over 110 locations in the world.

You will then have access to the ReactInstantSearchDOM object in the global scope (window).

const { InstantSearch, SearchBox, Hits } = ReactInstantSearchDOM;

const searchClient = algoliasearch('YourApplicationID', 'YourSearchOnlyAPIKey');

const App = () => (
  <InstantSearch searchClient={searchClient} indexName="demo_ecommerce">
    <SearchBox />
    <Hits />
  </InstantSearch>
);

Load the style

Afterwards, you need to manually load the companion CSS file into your page:

1
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/instantsearch.css@7.3.1/themes/reset-min.css" integrity="sha256-t2ATOGCtAIZNnzER679jwcFcKYfLlw01gli6F6oszk8=" crossorigin="anonymous">

Or you can load into your page the Algolia theme for the widgets to be styled.

1
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/instantsearch.css@7.3.1/themes/algolia-min.css" integrity="sha256-HB49n/BZjuqiCtQQf49OdZn63XuKFaxcIHWf0HNKte8=" crossorigin="anonymous">

You can find more information about that in the styling guide.

Create InstantSearch App

You can use create-instantsearch-app. Similarly to other interactive command line applications, you can run it either with npm or with yarn:

1
2
3
npx create-instantsearch-app 'getting-started'
# or
yarn create instantsearch-app 'getting-started'

Browser support

We support the last two versions of major browsers (Chrome, Edge, Firefox, Safari).

To support Internet Explorer 11, we recommend using polyfill.io. Add this script to your page to conditionally load polyfills:

1
<script src="https://polyfill.io/v3/polyfill.min.js?features=default,Array.prototype.find,Array.prototype.includes"></script>

Note that the code samples used in this documentation can use JavaScript syntax not natively supported by older browsers like Internet Explorer 11. If your site supports older browsers, make sure to use a tool like Babel to transform your code into code that works in the browsers you target.
