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

Require Syntax

Usage in a back-end node environment

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.

Deno

Usage in a back-end deno environment

import { MeiliSearch } from "https://esm.sh/meilisearch"

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

🎬 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('movies')

  const documents = [
      { id: 1, title: 'Carol', genres: ['Romance', 'Drama'] },
      { id: 2, title: 'Wonder Woman', genres: ['Action', 'Adventure'] },
      { id: 3, title: 'Life of Pi', genres: ['Adventure', 'Drama'] },
      { id: 4, title: 'Mad Max: Fury Road', genres: ['Adventure', 'Science Fiction'] },
      { id: 5, title: 'Moana', genres: ['Fantasy', 'Action']},
      { id: 6, title: 'Philadelphia', genres: ['Drama'] },
  ]

  // 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) // => { "uid": 0 }
})()

With the uid, you can check the status (enqueued, processing, succeeded or failed) of your documents addition using the task.

Basic Search 

// MeiliSearch is typo-tolerant:
const search = await index.search('philoudelphia')
console.log(search)

Output:

{
  "hits": [
    {
      "id": "6",
      "title": "Philadelphia",
      "genres": ["Drama"]
    }
  ],
  "offset": 0,
  "limit": 20,
  "nbHits": 1,
  "processingTimeMs": 1,
  "query": "philoudelphia"
}

Custom Search

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

await index.search(
  'wonder',
  {
    attributesToHighlight: ['*']
  }
)

{
  "hits": [
    {
      "id": 2,
      "title": "Wonder Woman",
      "genres": ["Action", "Adventure"],
      "_formatted": {
        "id": 2,
        "title": "<em>Wonder</em> Woman",
        "genres": ["Action", "Adventure"]
      }
    }
  ],
  "offset": 0,
  "limit": 20,
  "nbHits": 1,
  "processingTimeMs": 0,
  "query": "wonder"
}

Custom Search With Filters

If you want to enable filtering, you must add your attributes to the filterableAttributes index setting.

await index.updateAttributesForFaceting([
    'id',
    'genres'
  ])

You only need to perform this operation once.

Note that MeiliSearch will rebuild your index whenever you update filterableAttributes. Depending on the size of your dataset, this might take time. You can track the process using the tasks).

Then, you can perform the search:

await index.search(
  'wonder',
  {
    filter: ['id > 1 AND genres = Action']
  }
)

{
  "hits": [
    {
      "id": 2,
      "title": "Wonder Woman",
      "genres": ["Action","Adventure"]
    }
  ],
  "offset": 0,
  "limit": 20,
  "nbHits": 1,
  "processingTimeMs": 0,
  "query": "wonder"
}

Placeholder Search

Placeholder search makes it possible to receive hits based on your parameters without having any query (q). To enable faceted search on your dataset you need to add genres in the settings.

await index.search(
  '',
  {
    filter: ['genres = fantasy'],
    facetsDistribution: ['genres']
  }
)

{
  "hits": [
    {
      "id": 2,
      "title": "Wonder Woman",
      "genres": ["Action","Adventure"]
    },
    {
      "id": 5,
      "title": "Moana",
      "genres": ["Fantasy","Action"]
    }
  ],
  "offset": 0,
  "limit": 20,
  "nbHits": 2,
  "processingTimeMs": 0,
  "query": "",
  "facetsDistribution": {
    "genres": {
      "Action": 2,
      "Fantasy": 1,
      "Adventure": 1
    }
  }
}

Abortable Search

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

const controller = new AbortController()

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

controller.abort()
