Warning: This project has been published only to have a NPM release of fixing BeeJS issue 762

Client library for connecting to Bee decentralised storage

Warning: This project is in beta state. There might (and most probably will) be changes in the future to its API and working. Also, no guarantees can be made about its stability, efficiency, and security at this stage.

This project is intended to be used with Bee version 1.7.0. Using it with older or newer Bee versions is not recommended and may not work. Stay up to date by joining the official Discord and by keeping an eye on the releases tab.

> npm install @ethersphere/bee-js --save


> yarn add @ethersphere/bee-js

Be aware, if you are running Yarn v1 and are attempting to install this repo using GitHub URL, this won't unfortunately work as it does not correctly handle execution of prepare script.

Use in Node.js

We require Node.js's version of at least 12.x

var BeeJs = require("@ethersphere/bee-js");

Use in a browser with browserify, webpack or any other bundler

var BeeJs = require("@ethersphere/bee-js");

Use in a browser Using a script tag

Loading this module through a script tag will make the BeeJs object available in the global namespace.

<script src="https://unpkg.com/@ethersphere/bee-js/dist/index.browser.min.js"></script>


import { Bee } from "@ethersphere/bee-js"

bee = new Bee("http://localhost:1633")

// Be aware, this creates on-chain transactions that spend Eth and BZZ!
const batchId = await bee.createPostageBatch('100', 17)
const fileHash = await bee.uploadData(batchId, "Bee is awesome!")
const data = await bee.downloadData(fileHash)

console.log(data.text()) // prints 'Bee is awesome!'

There are some ways you can make this module better:

  • Consult our open issues and take on one of them
  • Help our tests reach 100% coverage!
  • Join us in our Discord chat in the #develop-on-swarm channel if you have questions or want to give feedback


Install project dependencies with

npm i


The tests run in both context: node and dom with Jest.

To run the integration tests, you need to spin up local Bee cluster using our bee-factory project. In order to do that you have to have locally Docker running on your machine, but afterwards you can just simply run npm run bee, which spins up the cluster and display Queen's logs. If you want to exit hit CTRL+C.

If you want to skip creation of postage stamps every run of integration tests you can create stamps for both nodes and set them under env. variables BEE_POSTAGE and BEE_PEER_POSTAGE.

By default, for integration tests two bee nodes are expected to run on localhost on addresses http://localhost:1633 and http://localhost:11633. These are the default values for the bee-factory script. If you want to use custom setup, you can change the behavior of tests to different addresses using environment variables BEE_API_URL, BEE_DEBUG_API_URL, BEE_PEER_DEBUG_API_URL and BEE_PEER_API_URL.

There are also browser tests by Puppeteer, which also provide integrity testing.

npm run test:browser

The test HTML file which Puppeteer uses is the test/testpage/testpage.html. To open and manually test BeeJS with developer console, it is necessary to build the library first with npm run compile:browser (running the browser tests npm run test:browser also builds the library).

Compile code

In order to compile NodeJS code run

npm run compile:node

or for Browsers

npm run compile:browser
