Bee-JS

FOSSA Status standard-readme compliant js-standard-style

JavaScript SDK for the Swarm decentralised storage.

Supports Node.js 18+, Vite and Webpack.

Write your code in CJS, MJS or TypeScript.

Intended to be used with Bee version 2.5.0.

Quick start

Start a Swarm project using TypeScript:

npm init swarm-app@latest my-dapp node-ts

or using Vite and TypeScript:

npm init swarm-app@latest my-dapp vite-tsx

Supported types are node, node-esm, node-ts and vite-tsx. Replace my-dapp with your project name.

Install

npm install @ethersphere/bee-js

Import

CJS

const { Bee } = require('@ethersphere/bee-js')

MJS and TypeScript

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

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>

Overview

Type interfaces

NumberString is a branded type for marking strings that represent numbers. It interops with string and bigint types. Where NumberString is present, number is disallowed in order to avoid pitfalls with unsafe large values.

Byte primitives

All the classes below extend Bytes, therefor the following methods are available on all of them: toUint8Array, toHex, toBase64, toBase32, toUtf8, toJSON, static keccak256, static fromUtf8.

The toString method uses toHex.

Bytes and its subclasses may be constructed with new from Uint8Array or hex string.

Tokens

Name Description Methods

Swarm primitives

Name Description Methods

Usage

Upload via Swarm Gateway

import { Bee, NULL_STAMP, SWARM_GATEWAY_URL } from '@ethersphere/bee-js'

main()

async function main() {
  const bee = new Bee(SWARM_GATEWAY_URL)
  const { reference } = await bee.uploadData(NULL_STAMP, 'Hello, World!')
  console.log(reference.toHex())
}

Create or select an existing postage batch

Swarm incentivizes nodes in the network to store content, therefor all uploads require a paid postage batch.

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

async function getOrCreatePostageBatch() {
  const bee = new Bee('http://localhost:1633')
  let batchId

  const batches = await bee.getAllPostageBatch()
  const usable = batches.find(x => x.usable)

  if (usable) {
    batchId = usable.batchID
  } else {
    batchId = await bee.buyStorage(Size.fromGigabytes(1), Duration.fromDays(7))
  }
}

The following examples all assume an existing batchId.

Upload simple data (Browser + Node.js)

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

const bee = new Bee('http://localhost:1633')

const uploadResult = await bee.uploadData(batchId, 'Bee is awesome!')
const data = await bee.downloadData(uploadResult.reference)

console.log(data.toUtf8()) // prints 'Bee is awesome!'

Upload data from a file input (React)

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

const bee = new Bee('http://localhost:1633')
const result = await bee.uploadFile(batchId, file)

Upload multiple files or a directory (React)

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

const bee = new Bee('http://localhost:1633')
const result = await bee.uploadFiles(batchId, fileList)

Upload arbitrary large file (Node.js)

import { Bee } from '@ethersphere/bee-js'
import { createReadStream } from 'fs'

const bee = new Bee('http://localhost:1633')
const readable = createReadStream('./path/to/large.bin')
const uploadResult = await bee.uploadFile(batchId, readable)

Upload arbitrary large directories (Node.js)

import { Bee } from '@ethersphere/bee-js'
import { createReadStream } from 'fs'

const bee = new Bee('http://localhost:1633')
const uploadResult = await bee.uploadFilesFromDirectory(batchId, './path/to/gallery/')

Customize http/https agent and headers

const bee = new Bee('http://localhost:1633', {
  httpAgent: new http.Agent({ keepAlive: true }),
  httpsAgent: new https.Agent({ keepAlive: true }),
  headers: {
    Authorization: 'Basic ' + Buffer.from('username:password').toString('base64'),
  },
})
