    apiKey: 'masterKey',
  })
</script>

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 in a ES 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()
