Features
- Easy programmatic trading.
- A customizable, websocket-synced Order Book implementation.
- API clients with convenient methods for every API endpoint.
- Abstracted interfaces – don't worry about HMAC signing or JSON formatting, the library does it for you.
- Semantic versioning.
Installation
# From NPM
npm install coinbase-exchange
# From Github
npm install coinbase/coinbase-exchange-nodeQuick Start
The Public API Client
The GDAX API has both public and private endpoints. If you're only
interested in the public endpoints, you should use a PublicClient.
var CoinbaseExchange = require('coinbase-exchange');
var publicClient = new CoinbaseExchange.PublicClient();All API methods are callback based. Your callback should accept three arguments:
var callback = function(err, response, data) {
// your code here.
};
This callback will be passed directly to the underlying request library's
request method. err will be either
null or an Error. response will be a generic HTTP response abstraction
created by the request library. data will be the result of JSON-decoding
the server's response, or null if the response was not parseable. You can
learn about the API responses of each endpoint by reading our
documentation.
Public API Methods
publicClient.getProducts(callback);// Get the order book at the default level of detail.
publicClient.getProductOrderBook(callback);
// Get the order book at a specific level of detail.
publicClient.getProductOrderBook({'level': 3}, callback);publicClient.getProductTicker(callback);publicClient.getProductTrades(callback);
// To make paginated requests, include page parameters
publicClient.getProductTrades({'after': 1000}, callback);getProductTradeStreamWraps aroundgetProductTrades, fetches all trades with IDs>= tradesFromand<= tradesTo. Handles pagination and rate limits.
var trades = publicClient.getProductTradeStream(8408000, 8409000);
// tradesTo can also be a function
var trades publicClient.getProductTradeStream(8408000, function(trade) {
return Date.parse(trade.time) >= 1463068e6
})publicClient.getProductHistoricRates(callback);
// To include extra parameters:
publicClient.getProductHistoricRates({'granularity': 3000}, callback);publicClient.getProduct24HrStats(callback);publicClient.getCurrencies(callback);publicClient.getTime(callback);The Authenticated API Client
The private exchange API endpoints require you to authenticate with an API key. You can create a new API key in your exchange account's settings.
var CoinbaseExchange = require('coinbase-exchange');
var authedClient = new CoinbaseExchange.AuthenticatedClient(
key, b64secret, passphrase);Like the PublicClient, all API methods are callback based. The callback
should be in the same format:
var callback = function(err, response, data) {
// your code here.
};
The AuthenticatedClient inherits all of the API methods defined by the
PublicClient, so if you're hitting both public and private API endpoints you
only need to create a single client.
Private API Methods
authedClient.getAccounts(callback);var accountID = '7d0f7d8e-dd34-4d9c-a846-06f431c381ba';
authedClient.getAccount(accountID, callback);var accountID = '7d0f7d8e-dd34-4d9c-a846-06f431c381ba';
authedClient.getAccountHistory(accountID, callback);
// For pagination, you can include extra page arguments
authedClient.getAccountHistory(accountID, {'before': 3000}, callback);var accountID = '7d0f7d8e-dd34-4d9c-a846-06f431c381ba';
authedClient.getAccountHolds(accountID, callback);
// For pagination, you can include extra page arguments
authedClient.getAccountHolds(accountID, {'before': 3000}, callback);// Buy 1 BTC @ 100 USD
var buyParams = {
'price': '100.00', // USD
'size': '1', // BTC
'product_id': 'BTC-USD',
};
authedClient.buy(buyParams, callback);
// Sell 1 BTC @ 110 USD
var sellParams = {
'price': '110.00', // USD
'size': '1', // BTC
'product_id': 'BTC-USD',
};
authedClient.sell(sellParams, callback);var orderID = 'd50ec984-77a8-460a-b958-66f114b0de9b';
authedClient.cancelOrder(orderID, callback);authedClient.cancelOrders(callback);// `cancelOrders` may require you to make the request multiple times until
// all the orders are deleted.
// `cancelAllOrders` will handle making these requests for you asyncronously.
// Also you can add a product_id param to only delete orders of that product
// The response will be the response of the last call and the data will
// have the order ID's of all your deleted orders
authedClient.cancelAllOrders({product_id: 'BTC-USD'}, callback);authedClient.getOrders(callback);
// For pagination, you can include extra page arguments
authedClient.getOrders({'after': 3000}, callback);var orderID = 'd50ec984-77a8-460a-b958-66f114b0de9b';
authedClient.getOrder(orderID, callback);authedClient.getFills(callback);
// For pagination, you can include extra page arguments
authedClient.getFills({'before': 3000}, callback);// Deposit to your Exchange USD account from your Coinbase USD account.
var depositParamsUSD = {
'amount': '100.00', // USD,
'coinbase_account_id': '60680c98bfe96c2601f27e9c', // USD Coinbase Account ID
};
authedClient.deposit(depositParamsUSD, callback);
// Withdraw from your Exchange USD account to your Coinbase USD account.
var withdrawParamsUSD = {
'amount': '100.00', // USD,
'coinbase_account_id': '60680c98bfe96c2601f27e9c', // USD Coinbase Account ID
};
authedClient.withdraw(withdrawParamsUSD, callback);
// Deposit to your Exchange BTC account from your Coinbase BTC account.
var depositParamsBTC = {
'amount': '2.0', // BTC,
'coinbase_account_id': '536a541fa9393bb3c7000023', // BTC Coinbase Account ID
};
authedClient.deposit(depositParamsBTC, callback);
// Withdraw from your Exchange BTC account to your Coinbase BTC account.
var withdrawParamsBTC = {
'amount': '2.0', // BTC,
'coinbase_account_id': '536a541fa9393bb3c7000023', // BTC Coinbase Account ID
};
authedClient.withdraw(withdrawParamsBTC, callback);Websocket client
<<<<<<< e614fa20dfbc8ce07ff909ddfd96e559f8925ffd
The WebsocketClient allows you to connect and listen to the
exchange websocket messages.
The WebsocketClient allows you to connect and listen to the
exchange websocket messages.
Add deprecation notice
var CoinbaseExchange = require('coinbase-exchange');
var websocket = new CoinbaseExchange.WebsocketClient();
websocket.on('message', function(data) { console.log(data); });The following events can be emitted from the WebsocketClient:
openmessageclose
Orderbook
Orderbook is a data structure that can be used to store a local copy of the orderbook.
var CoinbaseExchange = require('coinbase-exchange');
var orderbook = new CoinbaseExchange.Orderbook();The orderbook has the following methods:
state(book)get(orderId)add(order)remove(orderId)match(match)change(change)
Orderbook Sync
OrderbookSync creates a local mirror of the orderbook on GDAX using
Orderbook and WebsocketClient as described here.
var CoinbaseExchange = require('coinbase-exchange');
var orderbookSync = new CoinbaseExchange.OrderbookSync();
console.log(orderbookSync.book.state());Testing
