Install

npm

> npm install @ethersphere/bee-js

Use in Node.js

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

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

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

Use in a browser Using a script tag

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

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

Usage

import Bee from "@ethersphere/bee-js"; // Connect to a node const

bee = new Bee("http://localhost:8080");

const fileHash = await bee.upload("Bee is awesome!");
const retrievedData = await bee.download(fileHash);

console.log(retrievedData.toString()); // 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!

Setup

Install project dependencies with

npm i

Test

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

To run the test, you need to have a Bee cluster running locally. To create a cluster, please consult the readme of @ethersphere/bee-local.

By defaul tests are run against local bee node 0 - http://bee-0.localhost. You can change it by setting environment variable BEE_URL.

In Visual Studio environment, the tests have been set up to run against your local bee node on http://localhost:1633 To run Jest tests, choose the vscode-jest-tests CI job under the Run tab. You can run your own local Bee client for test purposes with the help of test/bee.sh. If you pass --ephemeral flag, the container automatically will be removed at the end of the run.

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. In order to open this file and manually test BeeJS via developer console, it's necessary to build the test JS file that it imports with npm run compile:window. This test JS file is identical with the Bee library itself, except it binds BeeJS functionalities to the browser's window object.

Compile code

In order to compile NodeJS code run

npm run compile:node

or for Browsers

npm run compile:browser
