bfx-api-node-plugin-wd

Bitfinex Packet Watch-dog Plugin for the Node.JS API

This plugin implements a watch-dog for the Bitfinex Node API. It can be initialized with a reconnection & watch dog delay, and will close the socket connection & automatically reconnect if no message arrives within the WD delay. It is meant to be used to detect and cycle stale socket connections.

Features

• Closes & re-opens connections if no packet arrives within the configured WD window

Installation

npm i --save bfx-api-node-plugin-wd

Quickstart & Example

const debug = require('debug')('bfx:api:plugins:wd:example')
const { Manager, subscribe } = require('bfx-api-node-core')
const WDPlugin = require('bfx-api-node-plugin-wd')

const mgr = new Manager({
  transform: true,

  // include watch-dog plugin on manager init
  plugins: [WDPlugin({
    autoReconnect: true,  // if false, the connection will only be closed
    reconnectDelay: 5000, // wait 5 seconds before reconnecting
    packetWDDelay: 10000  // set the watch-dog to a 10s delay
  })]
})

// Note that we do nothing here; the watch-dog will fire due to a lack of
// incoming messages
mgr.onWS('open', {}, (state = {}) => {
  debug('open')
})

mgr.openWS()
