How to stream trades from Binance web socket API in Node.js?

Question

I am trying to use the Binance API to get the latest trades on a crypto-currency pair. Here is the endpoint to the API, say for BTC/USDT: wss://stream.binance.com:9443/ws/btcusdt@trade

I tested this API on https://www.websocket.org/echo.html, and was successful in getting a continuous stream of new trades.

How do I use this API in Node.js to continuously output the trades on the console? Is there any specific library or package you recommend?

Answer 1

I feel kind of stupid for not finding this package earlier. I used ws to accomplish the task. Below are the lines of code I typed:

const WebSocket = require('ws');

const ws = new WebSocket('wss://stream.binance.com:9443/ws/btcusdt@trade');

ws.on('message', function incoming(data) {
    console.log(data);
});
