What is instantsearch.js?

instantsearch.js is a library for building performant and instant search experiences with Algolia. It provides a set of widgets and tools to create highly customizable search interfaces.

What are instantsearch.js's main functionalities?

Search Box

The search box widget allows users to input their search queries. It connects to the Algolia index and fetches results based on the user's input.

const search = instantsearch({
  indexName: 'instant_search',
  searchClient: algoliasearch('YourApplicationID', 'YourSearchOnlyAPIKey')
});

search.addWidget(
  instantsearch.widgets.searchBox({
    container: '#searchbox'
  })
);

search.start();

Hits

The hits widget displays the search results. It can be customized to show different attributes of the search results and highlight the matching parts of the query.

search.addWidget(
  instantsearch.widgets.hits({
    container: '#hits',
    templates: {
      item: '<div>{{#helpers.highlight}}{ "attribute": "name" }{{/helpers.highlight}}</div>'
    }
  })
);

Refinement List

The refinement list widget allows users to filter search results based on specific attributes, such as categories. It provides checkboxes for each attribute value.

search.addWidget(
  instantsearch.widgets.refinementList({
    container: '#refinement-list',
    attribute: 'categories'
  })
);

Pagination

The pagination widget enables users to navigate through pages of search results. It provides controls for moving to the next or previous page and jumping to specific pages.

search.addWidget(
  instantsearch.widgets.pagination({
    container: '#pagination'
  })
);

Why

You should be using InstantSearch if you want to:

• Design search experiences with best practices
• Customize your components at will
• Remain independent from external frameworks

Getting started

Using InstantSearch.js is as simple as adding this JavaScript code to your page:

// 1. Instantiate the search
const search = instantsearch({
  indexName: 'instant_search',
  searchClient: algoliasearch('latency', '6be0576ff61c053d5f9a3225e2a90f76'),
});

search.addWidgets([
  // 2. Create an interactive search box
  instantsearch.widgets.searchBox({
    container: '#searchbox',
    placeholder: 'Search for products',
  }),

  // 3. Plug the search results into the product container
  instantsearch.widgets.hits({
    container: '#products',
    templates: {
      item: (hit, { html, components }) =>
        html`
          <h3>${components.Highlight({ attribute: 'name', hit })}</h3>
          <p>${components.Snippet({ attribute: 'description', hit })}</p>
        `,
    },
  }),

  // 4. Make the brands refinable
  instantsearch.widgets.refinementList({
    container: '#brand',
    attribute: 'brand',
  }),
]);

// 5. Start the search!
search.start();

To use InstantSearch.js in a TypeScript environment, depending on your algoliasearch version, you need to import different types.

You still need to import these types even if you don't use InstantSearch.js with algoliasearch.

This version uses types provided by both algoliasearch and @algolia/client-search.

yarn add algoliasearch@4 @algolia/client-search

algoliasearch v3.x

yarn add @types/algoliasearch@3

v3.x is deprecated and will soon no longer be supported.
