@pioug/poloniex

A tiny Node.js wrapper for Poloniex API.

I created this module because I believe that simple and readable code matters for code audit since Poloniex API can be used for trading real money.

Features

• Complete implementation of Poloniex HTTP API
• About 100 lines on code
• One dependency (axios)
• Promise-based
• Environment variables for API key and secret

Setup

Requirements

• Node 8 (for object rest and spread properties support)
• npm 5.1.0 (for npm lockfiles support)

Installation

npm install --save @pioug/poloniex

Usage

It is recommended to use environment variables for POLONIEX_KEY and POLONIEX_SECRET:

POLONIEX_KEY=my_api_key POLONIEX_SECRET=my_secret node app.js

The wrapper API is following this format:

Poloniex.<command>(<Object with query strings or POST parameters>)

For authenticated requests (trading API), additional parameters can be passed:

• nonce: An integer which must always be greater than the previous nonce used
  • Optional
  • Default is Date.now()
• key: Your Poloniex API key
  • Optional
  • Default is process.env.POLONIEX_KEY
• secret: Your Poloniex key secret
  • Optional
  • Default is process.env.POLONIEX_SECRET

Every method returns a promise.

Code example

Public request

const Poloniex = require('@pioug/poloniex');

Poloniex.returnLoanOrders({
  currency: 'BTC'
})
  .then(console.log);

Authenticated request

const Poloniex = require('@pioug/poloniex');

Poloniex.buy({
  amount: '338.8732',
  currencyPair: 'BTC_XVC',
  rate: '0.00000173',

  nonce: 1
  key: 'my_api_key',
  secret: 'my_secret'
})
  .then(console.log);
