Coinalist

High level cryptocurrency exchange-agnostic framework for real time monitoring, trading and analytics. Based on easy to use "streams" and "observables" paradigm, as specified and implemented by ReactiveX.

Status: alpha

const coinalist = require('coinalist');
const { config, exchange: { ExchangeBinance } } = coinalist;
const { BTCUSD, BTCUSDT } = config.market.values;
const { BUY, SELL } = config.side.values;

const exchange = new ExchangeBinance();
exchange.init([BTCUSDT,]);

const marketBook = exchange.markets[0].books[BUY];
marketBook.subscribe(marketBook => {
  console.log('Order book (top etries):\n', marketBook.orders);
});

Expected output on the order book updates:
