cryptocurrency exchanges client api wrapper.

These features are supported with all major exchanges

• Public realtime api.
• Public rest api.
• Support for both Nodejs and Browser environments.
• Modular structure make sure you include minimum code as you need (especially for client side application).
• Option to bypass cors request problem in browser with proxy.
• More to come: Tradingview datafeed, private rest api with api/secret key...

• Angular sample
• Webpack typescript (future)
• Rollup typescript (future)

Binance, Bitbank, Bitfinex, Coinbase (Gdax)

	id	name	ver	doc	countries
	binance	Binance	*	API	Japan
	bitbank	Bitbank	1	API	Japan
	bitfinex	Bitfinex v2	2	API	British Virgin Islands
	coinbase	Coinbase	*	API	US

When you include a module you also include all of its dependencies

This library is designed to be usable in both nodejs and browser (with frontend framework like Angular, React, Vue..., with bundle tools like Webpack or Rollup having typescript configured, the umd javascript file coming later) environments.

When used in browser environment, the browser must support for native

• fetch
• websocket

npm i --save ccex-api

import { BinanceApi } from 'ccex-api/exchanges/binance;

const binanceApi = new BinanceApi();

binanceApi.fetchTicker$('btc_usdt').subscribe(ticker => console.log(ticker));
binanceApi.ticker$('btc_usdt').subscribe(ticker => console.log(ticker));
setTimeout(() => { binanceApi.stopTicker('btc_usdt') }, 5000);

Or you can include only the part that you need

import { BitbankCandlestick } from 'ccex-api/exchanges/bitbank/candlestick;

const bitbankCandlestick = new BitbankCandlestick();
bitbankCandlestick.getApproximateHistoryPrice('btc_jpy', 1526917534904, 1).subscribe(price => console.log(price));

• Pair (market/symbol): must have the following format btc_usd (lowercase with underscore between 2 asset)

Basically all exchanges have these following unified, generalized api implemented.

Besides, an exchange may have more specific functions, it depends on exchange provided features and implementation. In that case, specific guide for that exchange will be located at exchanges/{exchange}/README.md (future)

In order to add a new exchange, simply clone folder src/exchanges/sample, rename, implement functions and include appropiate tests for sub-modules (ticker, orderbook...) and some internal functions (future)

Finally make sure the exchange sample pass predefined test by running (future)

npm run main-test --exchange sample

If you find a bug or anything should be added to fit your need, please create issue. This is still in very early stage so any feedback would be much appreciated.

main test: test for main module which implement the above interface directly

npm run main-test

sub test: test for sub-modules used inside main module and its internal functions

npm run sub-test

This library is built strongly on top of Rxjs (v6 or above)

• Rxjs
• pubnub
• node-fetch (nodejs only)
• ws (nodejs only)
