Node Kraken

NodeJS Client Library for the Kraken (kraken.com) API

This is an asynchronous node js client for the kraken.com API. It exposes all the API methods found here: https://www.kraken.com/help/api through the api method.

Please note that when you make more than one API call and correctly set the nonce so that it is always larger than the previous nonce, the requests might arrive to Kraken out of order, which guarantees that Kraken will seen an "Invalid Nonce". You can fix this by allowing your nonces to go backwards during a small "Nonce Window", which uses milliseconds as units. I had to set mine to 5000.

Installation

npm install kraka-djs

Example Usage:

const key          = '...'; // API Key
const secret       = '...'; // API Private Key
const KrakenClient = require('kraken-api');
const kraken       = new KrakenClient(key, secret);

(async () => {
	// Display user's balance
	console.log(await kraken.api('Balance'));

	// Get Ticker Info
	console.log(await kraken.api('Ticker', { pair : 'XXBTZUSD' }));
})();

Updates:

1.0.3:

• Added CancelOrderBatch to private methods.
• Allows parameter Object to contain a property ctr which is added to the nonce to differentiate same-ms requests.

1.0.2 (Imported):

• Removes any added nonce to prevent reuse nothingisdead #77
• Added CancelAll to private methods nothingisdead #73

1.0.1 (links here and below are all to nothingisdead's repo):

• Update dependencies
• Update required NodeJS version: #42
• Add GetWebSocketsToken private method: #65
• Update README: #44

1.0.0:

• All methods return a promise.
• The second argument (parameters) can be omitted.
• The third argument to the constructor can be an object (configuration) or a string (OTP), for backwards compatibility.

0.1.0:

The callback passed to the api function conforms to the Node.js standard of

function(error, data) {
	// ...
}

Thanks to @tehsenaus and @petermrg for pointing this out.
