kraken-api-js

JavaScript full support of kraken-api.
Originally kraken-api is CommonJS friendly only. This package is a port for CommonJS, ES2015 Module and TypeScript support.

Imports

CommonJS

const { KrakenClient } = require('kraken-api-js')

ES-Module

import { KrakenClient } from 'kraken-api-js'

TypeScript (typings included)

import { KrakenClient } from 'kraken-api-js'

Usage

const key = '' // your API key
const privateKey = '' // your API private key
const kraken = new KrakenClient(key, privateKey)

/* examples */
const main = async () => {
  // public endpoint
  const {result} = await kraken.api('Ticker', { pair: 'XRPUSD' })
  console.log(result.XXRPZUSD.c) // print current USD value of XRP

  // private endpoint
  const {result} = await kraken.api('Balance')
  console.log(result.XXBT) // print how much bitcoins you have on your account right now
}

main()

Below is a list of the different methods you can call. To see the parameters you have to provide to each method please refer to the official Kraken API page

public methods

Time Assets AssetPairs Ticker Depth Trades Spread OHLC

private methods

Balance TradeBalance OpenOrders ClosedOrders QueryOrders TradesHistory QueryTrades OpenPositions Ledgers QueryLedgers TradeVolume AddOrder CancelOrder DepositMethods DepositAddresses DepositStatus WithdrawInfo Withdraw WithdrawStatus WithdrawCancel GetWebSocketsToken

import methods list

The array of both public and private methods can be imported into your project

/* commonjs */
const { KrakenMethods } = require('kraken-api-js')

/* es-module & typescript */
import { KrakenMethods } from 'kraken-api-js'

Errors handling

In kraken-api if the response from the API contains an error the api method will throw an Error. In this version, the response is always a json object, giving you more freedom to handle the errors :

try {
  const {result, error} = await client.api('Ticker', { pair: 'fakePair' })
  if (error.length > 0) {
    console.log(`Response contains errors [ ${error.join(', ')} ]`)
    return
  }
  else if (result) {
    console.log('Response is clean')
    console.log(result)
  }
} catch (e) {
  // this piece of code will only get executed if the API couldn't be reached
  // (e.g. if the network has no connection to internet)
  console.log('the API couldn\'t be reached')
}
