Node.js & JavaScript SDK for Binance REST APIs & WebSockets

Updated & performant JavaScript & Node.js SDK for the Binance REST APIs and WebSockets:

• Extensive integration with Binance REST APIs and WebSockets.
• TypeScript support (with type declarations for most API requests & responses).
• Supports Binance REST APIs for Binance Spot, Margin, Isolated Margin, USDM & CoinM Futures.
  • Strongly typed on most requests and responses.
  • Automated end-to-end tests on most API calls, ensuring no breaking changes are released.
• Extremely robust & performant JavaScript/Node.js Binance SDK with significant trading volume in production (livenet).
• Actively maintained with a modern, promise-driven interface.
• Support for seamless HMAC and RSA authentication for private Binance REST API and WebSocket calls.
  • Passing a private key as a secret will automatically revert to RSA authentication.
• Supports Websockets for Binance Spot, Margin, Isolated Margin, USDM & CoinM Futures.
  • Event driven messaging.
  • Smart websocket persistence
    • Automatically handle silent websocket disconnections through timed heartbeats, including the scheduled 24hr disconnect.
    • Automatically handle listenKey persistence and expiration/refresh.
    • Emit reconnected event when dropped connection is restored.
  • Strongly typed on most websocket events, with typeguards available for TypeScript users.
  • Optional:
    • Automatic beautification of Websocket events (from one-letter keys to descriptive words, and strings with floats to numbers).
    • Automatic beautification of REST responses (parsing numbers in strings to numbers).
• Heavy automated end-to-end testing with real API calls.
  • End-to-end testing before any release.
  • Real API calls in e2e tests.
• Proxy support via axios integration.
• Active community support & collaboration in telegram: Node.js Algo Traders.

Documentation

Most methods accept JS objects. These can be populated using parameters specified by Binance's API documentation.

• Binance API Documentation

Structure

This project uses typescript. Resources are stored in 3 key structures:

• src - the whole connector written in typescript
• lib - the javascript version of the project (compiled from typescript). This should not be edited directly, as it will be overwritten with each release.
• dist - the packed bundle of the project for use in browser environments.

REST API Clients

There are several REST API modules as there are some differences in each API group.

1. MainClient for most APIs, including: spot, margin, isolated margin, mining, BLVT, BSwap, Fiat & sub-account management.
2. USDMClient for USD-M futures APIs.
3. CoinMClient for COIN-M futures APIs.

Vanilla Options connectors are not yet available, though contributions are welcome!

REST Spot/Margin/etc

Start by importing the spot client. API credentials are optional, though an error is thrown when attempting any private API calls without credentials.

const { MainClient } = require('binance');

const API_KEY = 'xxx';
const API_SECRET = 'yyy';

const client = new MainClient({
  api_key: API_KEY,
  api_secret: API_SECRET,
});

client
  .getAccountTradeList({ symbol: 'BTCUSDT' })
  .then((result) => {
    console.log('getAccountTradeList result: ', result);
  })
  .catch((err) => {
    console.error('getAccountTradeList error: ', err);
  });

client
  .getExchangeInfo()
  .then((result) => {
    console.log('getExchangeInfo inverse result: ', result);
  })
  .catch((err) => {
    console.error('getExchangeInfo inverse error: ', err);
  });

See spot-client.ts for further information.

REST USD-M Futures

Start by importing the usd-m client. API credentials are optional, though an error is thrown when attempting any private API calls without credentials.

const { USDMClient } = require('binance');

const API_KEY = 'xxx';
const API_SECRET = 'yyy';

const client = new USDMClient({
  api_key: API_KEY,
  api_secret: API_SECRET,
});

client
  .getBalance()
  .then((result) => {
    console.log('getBalance result: ', result);
  })
  .catch((err) => {
    console.error('getBalance error: ', err);
  });

client
  .get24hrChangeStatististics()
  .then((result) => {
    console.log('get24hrChangeStatististics inverse futures result: ', result);
  })
  .catch((err) => {
    console.error('get24hrChangeStatististics inverse futures error: ', err);
  });

See usdm-client.ts for further information.

REST COIN-M Futures

Start by importing the coin-m client. API credentials are optional, though an error is thrown when attempting any private API calls without credentials.

const { CoinMClient } = require('binance');

const API_KEY = 'xxx';
const API_SECRET = 'yyy';

const client = new CoinMClient({
  api_key: API_KEY,
  api_secret: API_SECRET,
});

client
  .getSymbolOrderBookTicker()
  .then((result) => {
    console.log('getSymbolOrderBookTicker result: ', result);
  })
  .catch((err) => {
    console.error('getSymbolOrderBookTicker error: ', err);
  });

See coinm-client.ts for further information.

WebSockets

All websockets are accessible via the shared WebsocketClient. As before, API credentials are optional unless the user data stream is required.

const { WebsocketClient } = require('binance');

const API_KEY = 'xxx';
const API_SECRET = 'yyy';

// optionally override the logger
const logger = {
  ...DefaultLogger,
  silly: (...params) => {},
};

const wsClient = new WebsocketClient(
  {
    api_key: key,
    api_secret: secret,
    beautify: true,
    // Disable ping/pong ws heartbeat mechanism (not recommended)
    // disableHeartbeat: true
  },
  logger,
);

// receive raw events
wsClient.on('message', (data) => {
  console.log('raw message received ', JSON.stringify(data, null, 2));
});

// notification when a connection is opened
wsClient.on('open', (data) => {
  console.log('connection opened open:', data.wsKey, data.ws.target.url);
});

// receive formatted events with beautified keys. Any "known" floats stored in strings as parsed as floats.
wsClient.on('formattedMessage', (data) => {
  console.log('formattedMessage: ', data);
});

// read response to command sent via WS stream (e.g LIST_SUBSCRIPTIONS)
wsClient.on('reply', (data) => {
  console.log('log reply: ', JSON.stringify(data, null, 2));
});

// receive notification when a ws connection is reconnecting automatically
wsClient.on('reconnecting', (data) => {
  console.log('ws automatically reconnecting.... ', data?.wsKey);
});

// receive notification that a reconnection completed successfully (e.g use REST to check for missing data)
wsClient.on('reconnected', (data) => {
  console.log('ws has reconnected ', data?.wsKey);
});

// Recommended: receive error events (e.g. first reconnection failed)
wsClient.on('error', (data) => {
  console.log('ws saw error ', data?.wsKey);
});

// Call methods to subcribe to as many websockets as you want.
// Each method spawns a new connection, unless a websocket already exists for that particular request topic.
// wsClient.subscribeSpotAggregateTrades(market);
// wsClient.subscribeSpotTrades(market);
// wsClient.subscribeSpotKline(market, interval);
// wsClient.subscribeSpotSymbolMini24hrTicker(market);
// wsClient.subscribeSpotAllMini24hrTickers();
// wsClient.subscribeSpotSymbol24hrTicker(market);
// wsClient.subscribeSpotAll24hrTickers();
// wsClient.subscribeSpotSymbolBookTicker(market);
// wsClient.subscribeSpotAllBookTickers();
// wsClient.subscribeSpotPartialBookDepth(market, 5);
// wsClient.subscribeSpotDiffBookDepth(market);

wsClient.subscribeSpotUserDataStream();
wsClient.subscribeMarginUserDataStream();
wsClient.subscribeIsolatedMarginUserDataStream('BTCUSDT');

wsClient.subscribeUsdFuturesUserDataStream();

// each method also restores the WebSocket object, which can be interacted with for more control
// const ws1 = wsClient.subscribeSpotSymbolBookTicker(market);
// const ws2 = wsClient.subscribeSpotAllBookTickers();
// const ws3 = wsClient.subscribeSpotUserDataStream(listenKey);

// optionally directly open a connection to a URL. Not recommended for production use.
// const ws4 = wsClient.connectToWsUrl(`wss://stream.binance.com:9443/ws/${listenKey}`, 'customDirectWsConnection1');

See websocket-client.ts for further information. Also see ws-userdata.ts for user data examples.

Customise Logging

Pass a custom logger which supports the log methods silly, debug, notice, info, warning and error, or override methods from the default logger as desired.

const { WebsocketClient, DefaultLogger } = require('binance');

// Enable all logging on the silly level
DefaultLogger.silly = (...params) => {
  console.log('sillyLog: ', params);
};

const ws = new WebsocketClient(
  api_key: 'xxx',
  api_secret: 'yyyy',
  DefaultLogger
);

Browser/Frontend Usage

Import

This is the "modern" way, allowing the package to be directly imported into frontend projects with full typescript support.

1. Install these dependencies

   npm install crypto-browserify stream-browserify
   

2. Add this to your tsconfig.json

   {
     "compilerOptions": {
       "paths": {
         "crypto": [
           "./node_modules/crypto-browserify"
         ],
         "stream": [
           "./node_modules/stream-browserify"
         ]
   }
   

3. Declare this in the global context of your application (ex: in polyfills for angular)

   (window as any).global = window;
   

Webpack

This is the "old" way of using this package on webpages. This will build a minified js bundle that can be pulled in using a script tag on a website.

Build a bundle using webpack:

• npm install
• npm build
• npm pack

The bundle can be found in dist/. Altough usage should be largely consistent, smaller differences will exist. Documentation is still TODO.

However, note that browser usage will lead to CORS errors due to Binance.
