How to import MeiliSearch

Node - CommonJs

const MeiliSearch = require('meilisearch')

Browser - vanilla JS

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

EcmaScript module - esm

import MeiliSearch from 'meilisearch'

Important, if your bundler uses browser as primary entry key, please change it to module.
Example in webpack:

resolve: {
    mainFields: ["module", "browser"] // the `module` field has priority on the browser field
  },

EcmaScript module Typescript - esm

import MeiliSearch, { Index, SearchResponse } from 'meilisearch'
