npm version Tests License Bors enabled

Meilisearch is an open-source search engine. Discover what Meilisearch is!

This library is the search client that you should use to make Meilisearch work with autocomplete. Autocomplete, an open-source project developed by Algolia, is a library that lets you quickly build an autocomplete experience.

Since autocomplete.js provides the possibility to use a custom data source, we are able to plug into it. Nonetheless, it has been created by Algolia and thus some of its components only works with Algolia.

🔧 Installation

Use npm or yarn to install the autocomplete client for Meilisearch.

yarn add @meilisearch/autocomplete-client
# or
npm install @meilisearch/autocomplete-client

@meilisearch/autocomplete-client is a client for autocomplete. It does not import the library.
To be able to use both, you need to install autocomplete as well.

🎬 Usage

The Meilisearch Autocomplete client provides 2 methods:

  • meilisearchAutocompleteClient({ host, url, options? }): The search client.
    • url: The URL to your Meilisearch instance.
    • apiKey: A valid API key with enough rights to search. ⚠️ Avoid using the admin key or master key
    • options: Additional options. See this section
  • getMeilisearchResults(searchClient, queries): The data source handler.
    • searchClient: The client created with meilisearchAutocompleteClient
    • queries: An array of queries. See this documentation on what queries accepts.

🎬 Getting started

To make autocomplete work with Meilisearch, create the autocompleteSearchClient and provide it to the getMeilisearchResults method as the searchClient. The following code provides a basic working code example.

import { autocomplete } from '@algolia/autocomplete-js'
import {
  meilisearchAutocompleteClient,
  getMeilisearchResults,
} from '@meilisearch/autocomplete-client'
import '@algolia/autocomplete-theme-classic'

const searchClient = meilisearchAutocompleteClient({
  url: 'https://ms-adf78ae33284-106.lon.meilisearch.io', // Host
  apiKey: 'a63da4928426f12639e19d62886f621130f3fa9ff3c7534c5d179f0f51c4f303'  // API key
})

autocomplete({
  container: '#autocomplete',
  placeholder: 'Search for games',
  getSources({ query }) {
    return [
      {
        sourceId: 'steam-video-games',
        getItems() {
          return getMeilisearchResults({
            searchClient,
            queries: [
              {
                indexName: 'steam-video-games',
                query,
              },
            ],
          })
        },
        templates: {
          item({ item, components, html }) {
            return html`<div>
              <div>${item.name}</div>
            </div>`
          },
        },
      },
    ]
  },
})

💅 Customization

The options field in the meilisearchAutocompleteClient function provides the possibility to alter the default behavior of the search.

const client = meilisearchAutocompleteClient({
  url: 'http://localhost:7700',
  apiKey: 'searchKey',
  options: {
    placeholderSearch: false,
  },
})

Placeholder Search

Placeholders search means showing results even when the search query is empty. By default it is true. When placeholder search is set to false, no results appears when the search box is empty.

{ placeholderSearch : true } // default true

Primary key

Specify the field in your documents containing the unique identifier (undefined by default). By adding this option, we avoid errors that are thrown in some environments. For example, In React particularly, this option removes the Each child in a list should have a unique "key" prop error.

{ primaryKey : 'id' } // default: undefined

Keep zero facets

keepZeroFacets set to true keeps the facets even when they have 0 matching documents (default false).

If in your autocomplete implementation you are showing the facet values distribution, same values may completely disapear when they have no matching documents in the current filtering state.

By setting this option to true, the facet values do not disapear and instead are given the distribution 0.

With keepZeroFacets set to true:

genres:

  • horror (2000)
  • thriller (214)
  • comedy (0)

With keepZeroFacets set to false, comedy disapears:

genres:

  • horror (2000)
  • thriller (214)
{ keepZeroFacets : true } // default: false

Matching strategy

matchingStrategy gives you the possibility to choose how Meilisearch should handle the presence of multiple query words, see documentation.

For example, if your query is hello world by default Meilisearch returns documents containing either both hello and world or documents that only contain hello. This is the last strategy, where words are stripped from the right. The other strategy is all, where both hello and world must be present in a document for it to be returned.

{ matchingStrategy: 'all' }  // default last

Request Config

You can provide a custom request configuration. Available field can be found here.

For example, with custom headers:

{
  requestConfig: {
    headers: {
      Authorization: AUTH_TOKEN
    },
    credentials: 'include'
  }
}

Custom HTTP client

You can use your own HTTP client, for example, with axios.

{
  httpClient: async (url, opts) => {
    const response = await $axios.request({
      url,
      data: opts?.body,
      headers: opts?.headers,
      method: (opts?.method?.toLocaleUpperCase() as Method) ?? 'GET'
    })
    return response.data
  }
}
