Install

npm

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

Use in Node.js

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>

Usage

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

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

const fileHash = await bee.uploadData("Bee is awesome!")
const retrievedData = await bee.downloadData(fileHash)

console.log(new TextDecoder().decode(retrievedData)) // prints 'Bee is awesome!'

Setup

Install project dependencies with

npm i

Test

The tests run in both context: node and dom 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 default, tests are run against local bee node 0 - http://bee-0.localhost. You can change it by setting environment variable BEE_API_URL. In order to run tests which require one more node, you need to define BEE_PEER_API_URL as well. Its default value http://bee-1.localhost

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. 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
