iota.lib.js.powsrvio - Use powsrv.io PoW with IOTA.js Library

This library is used to add an alternative attachToTangle function to the iota.js library to delegate Proof-of-work to powsrv.io. This enables for users to offload PoW from low-power IoT devices, mobile and desktop devices without capabilities.

Getting Started

Add the package to your project:

npm install powsrv.js

Basic Usage

const remoteATT = require('powsrv.js')
const attachToTangle = remoteATT(5000, "your9api9key")

// Set attachToTangle to your IOTA client
const { composeAPI } = require('@iota/core')
const iota = composeAPI({
  provider: 'http://localhost:14265',
  attachToTangle
})

1. delay: Integer Milliseconds to wait before PoW server timeout. Null value defaults to 5000
2. key: String API key used to get access to powsrv.io.

API Key
