Bitfinex Trading API for Node.JS. Bitcoin, Ether and Litecoin trading

=========

Fork

This is a fork - please read the original docs: https://github.com/bitfinexcom/bitfinex-api-node

A Node.JS reference implementation of the Bitfinex API. See the full docs at http://bitfinexcom.github.io/bitfinex-api-node/

• Official implementation
• REST API
• WebSockets API

Installation

  npm install bitfinex-api-node

Usage

Version 1.0.0 supports the new v2 Websocket and Rest API. As Network calls are slow, the data is sent as lists.

In order to reconstruct key / value pairs, set opts.transform to true.

const BFX = require('bitfinex-api-node')

const API_KEY = 'secret'
const API_SECRET = 'secret'

const opts = {
  version: 2,
  transform: true
}

const bws = new BFX(API_KEY, API_SECRET, opts).ws

bws.on('auth', () => {
  // emitted after .auth()
  // needed for private api endpoints

  console.log('authenticated')
  // bws.submitOrder ...
})

bws.on('open', () => {
  bws.subscribeTicker('BTCUSD')
  bws.subscribeOrderBook('BTCUSD')
  bws.subscribeTrades('BTCUSD')

  // authenticate
  // bws.auth()
})

bws.on('orderbook', (pair, book) => {
  console.log('Order book:', book)
})

bws.on('trade', (pair, trade) => {
  console.log('Trade:', trade)
})

bws.on('ticker', (pair, ticker) => {
  console.log('Ticker:', ticker)
})

bws.on('error', console.error)

new BFX(API_KEY, API_SECRET, opts)

Where opts can be:

const opts = {
  // use v1 or v2 of the API, values: 1, 2
  version: 2,
  // transform lists for the v2 API. values: true, false, function
  transform: true
}

Version 1.0.0 Breaking changes:

constructor takes an options object now, instead of version number:

Old:

new BFX(API_KEY, API_SECRET, 2)

since 1.0.0:

new BFX(API_KEY, API_SECRET, { version: 2 })

Note version must be of type Number.

trade and orderbook snapshots are emitted as nested lists

To make dealing with snapshots better predictable, snapshots are emitted as an array.

normalized orderbooks for R0

Lists of raw orderbooks (R0) are ordered in the same order as P0, P1, P2, P3
