Kuzzle Javascript SDK

This is the official Javascript SDK for the free and open-source backend Kuzzle. It provides a way to dial with a Kuzzle server from Javascript applications using protocols.


Currently, the SDK provides 2 protocols: Http and WebSocket. WebSocket protocol implement the whole Kuzzle API, while the HTTP protocol does not implement realtime features (rooms and subscriptions).

Promises based

All SDK methods return a promise resolving the result part of Kuzzle API responses. If an error occurs, the promise is rejected with an Error object embedding the error part of the API response.
For example, for the action create of the controller collection (collection:create), the property result contains { "acknowledged": true } . This is therefore what will be returned by the SDK method if successful.
Any error must be caught either at the end of the Promise chain, or by using async/await and a try...catch.

Getting started 👉


This SDK can be used either in NodeJS or in a browser.


npm install kuzzle-sdk


To run the SDK in the browser, you have to build it yourself by cloning this repository and running

$ npm install
$ npm run build

A dist directory will be created, containing a browser version of this SDK.

<script type="text/javascript" src="dist/kuzzle.min.js"></script>

or use the CDN:

<script type="text/javascript" src="https://cdn.jsdelivr.net/npm/kuzzle-sdk@latest/dist/kuzzle.min.js"></script>

Then the Kuzzle SDK will be available under the KuzzleSDK variable:

    const kuzzle = new KuzzleSDK.Kuzzle(
      new KuzzleSDK.WebSocket('localhost')
    // ...

Browser with Webpack

If you use Webpack, you'll likely use the NPM-packaged version of the SDK (like in Node)

npm install kuzzle-sdk

But you'll still need to pick the built version (which ships with the package).

// with the classic require...
const { Kuzzle } = require('kuzzle-sdk')
// ... or with the new import directive.
import { Kuzzle } from 'kuzzle-sdk'


The SDK supports different protocols. When instantiating, you must choose the protocol to use and fill in the different options needed to connect to Kuzzle.

const { Kuzzle,  WebSocket } = require('kuzzle-sdk');
const kuzzle = new Kuzzle(
  new WebSocket('localhost', { port: 7512 })

try {
  await kuzzle.connect();
  const serverTime = await kuzzle.server.now();
} catch (error) {


npm i kuzzle-sdk
