binance-api-networks

Installation

npm install binance-api-networks

2021-02-01

Binance API supports Supports Deposits and Withdrawals for Interoperable Tokens. For example, you can deposit USDT based on OMNI, ERC20 or TRC20 into Binance.

Latest Binance API docs

We name this modules as to binance-api-networks, which is based on top of https://github.com/Ashlar/binance-api-node Version 0.9.15. Follwings are the docs from binance-api-node.

Getting started

Import the module and create a new client. Passing api keys is optional only if you don't plan on doing authenticated calls. You can create an api key here.

import Binance from 'binance-api-networks'

const client = Binance()

// Authenticated client, can make signed calls
const client2 = Binance({
  apiKey: 'xxx',
  apiSecret: 'xxx',
  getTime: xxx,
})

client.time().then(time => console.log(time))

If you do not have an appropriate babel config, you will need to use the basic commonjs requires.

const Binance = require('binance-api-networks').default

Every REST method returns a Promise, making this library async await ready. Following examples will use the await form, which requires some configuration you will have to lookup.

Init

Param	Type	Required	Info
apiKey	String	false	Required when making private calls
apiSecret	String	false	Required when making private calls
getTime	Function	false	Time generator, defaults to () => Date.now()

Futures WebSockets

Every websocket utility returns a function you can call to close the opened connection and avoid memory issues.

const clean = client.ws.futuresDepth('ETHBTC', depth => {
  console.log(depth)
})

// After you're done
clean()

Each websocket utility supports the ability to get a clean callback without data transformation, for this, pass the third attribute FALSE.

const clean = client.ws.futuresDepth('ETHBTC', depth => {
  console.log(depth)
}, false)

{
  "e": "depthUpdate", // Event type
  "E": 123456789,     // Event time
  "T": 123456788,     // transaction time 
  "s": "BTCUSDT",      // Symbol
  "U": 157,           // First update ID in event
  "u": 160,           // Final update ID in event
  "pu": 149,          // Final update Id in last stream(ie `u` in last stream)
  "b": [              // Bids to be updated
    [
      "0.0024",       // Price level to be updated
      "10"            // Quantity
    ]
  ],
  "a": [              // Asks to be updated
