Import

Front End or ESmodule
import MeiliSearch from 'meilisearch'

const client = new MeiliSearch({
  host: 'http://127.0.0.1:7700',
  apiKey: 'masterKey',
})
HTML Import
<script src="https://cdn.jsdelivr.net/npm/meilisearch@latest/dist/bundles/meilisearch.umd.js"></script>
<script>
  const client = new MeiliSearch({
    host: 'http://127.0.0.1:7700',
    apiKey: 'masterKey',
  })
  client.listIndexes().then(res => {
    console.log({ res });
  })
</script>
Back-End CommonJs
const MeiliSearch = require('meilisearch')

const client = new MeiliSearch({
  host: 'http://127.0.0.1:7700',
  apiKey: 'masterKey',
})
React Native

To make this package work with React Native, please add the react-native-url-polyfill.

🎬 Getting Started

Add Documents
const MeiliSearch = require('meilisearch')
// Or if you are on a front-end environment:
import MeiliSearch from 'meilisearch'

;(async () => {
  const client = new MeiliSearch({
    host: 'http://127.0.0.1:7700',
    apiKey: 'masterKey',
  })

  // An index is where the documents are stored.
  const index = client.index('books') // If your index exists

  const documents = [
    { book_id: 123, title: 'Pride and Prejudice' },
    { book_id: 456, title: 'Le Petit Prince' },
    { book_id: 1, title: 'Alice In Wonderland' },
    { book_id: 1344, title: 'The Hobbit' },
    { book_id: 4, title: 'Harry Potter and the Half-Blood Prince', genre: 'fantasy' },
    { book_id: 42, title: "The Hitchhiker's Guide to the Galaxy", genre: 'fantasy' }
  ]

  // If the index 'movies' does not exist, MeiliSearch creates it when you first add the documents.
  let response = await index.addDocuments(documents)

  console.log(response) // => { "updateId": 0 }
})()

With the updateId, you can check the status (enqueued, processed or failed) of your documents addition using the update endpoint.

Basic Search
// MeiliSearch is typo-tolerant:
const search = await index.search('harry pottre')
console.log(search)

Output:

{
  "hits": [
    {
      "book_id": 4,
      "title": "Harry Potter and the Half-Blood Prince"
    }
  ],
  "offset": 0,
  "limit": 20,
  "nbHits": 1,
  "exhaustiveNbHits": false,
  "processingTimeMs": 1,
  "query": "harry pottre"
}
Custom Search

All the supported options are described in the search parameters section of the documentation.

await index.search(
  'prince',
  {
    attributesToHighlight: ['*'],
    filters: 'book_id > 10'
  }
)
{
  "hits": [
    {
      "book_id": 456,
      "title": "Le Petit Prince",
      "_formatted": {
        "book_id": 456,
        "title": "Le Petit <em>Prince</em>"
      }
    }
  ],
  "offset": 0,
  "limit": 20,
  "nbHits": 1,
  "exhaustiveNbHits": false,
  "processingTimeMs": 0,
  "query": "prince"
}
Placeholder Search

Placeholder search makes it possible to receive hits based on your parameters without having any query (q).

await index.search(
  '',
  {
    facetFilters: ['genre:fantasy'],
    facetsDistribution: ['genre']
  }
)
{
  "hits": [
    {
      "id": 4,
      "title": "Harry Potter and the Half-Blood Prince",
      "genre": "fantasy"
    },
    {
      "id": 42,
      "title": "The Hitchhiker's Guide to the Galaxy",
      "genre": "fantasy"
    }
  ],
  "offset": 0,
  "limit": 20,
  "nbHits": 2,
  "exhaustiveNbHits": false,
  "processingTimeMs": 0,
  "query": "",
  "facetsDistribution": { "genre": { "fantasy": 2 } },
  "exhaustiveFacetsCount": true
}
Abortable Search

You can abort a pending search request by providing an AbortSignal to the request.

const controller = new AbortController()

index
  .search('prince', {}, 'POST', {
    signal: controller.signal,
  })
  .then((response) => {
    /** ... */
  })
  .catch((e) => {
    /** Catch AbortError here. */
  })

controller.abort()
