Kraken Go

Go library for Kraken Websocket and REST API

Installation Websocket package

go get github.com/aopoltorzhicky/go_kraken/websocket

Installation REST API package

Now only Public API realized. Private API is under developing.

go get github.com/aopoltorzhicky/go_kraken/rest

Usage

To learn how you can use the package read examples.

For quick start read the one below:

package main

import (
	"log"

	ws "github.com/aopoltorzhicky/go_kraken/websocket"
)

func main() {
	c := ws.New(false)
	err := c.Connect()
	if err != nil {
		log.Fatal("Error connecting to web socket : ", err)
	}

	err = c.Ping()
	if err != nil {
		log.Fatal(err)
	}

	// subscribe to BTCUSD, XLMUSD, ADACAD spread
	err = c.SubscribeSpread([]string{ws.BTCUSD, ws.XLMUSD, ws.ADACAD})
	if err != nil {
		log.Fatal(err)
	}

	for obj := range c.Listen() {
		switch obj.(type) {
		case error:
			log.Printf("channel closed: %s", obj)
		case ws.DataUpdate:
			data := obj.(ws.DataUpdate)
			log.Printf("MSG RECV: %#v", data)
		default:
		}
	}
}

To learn how to use REST API read example below:

package main

import (
	"log"

	"github.com/aopoltorzhicky/go_kraken/rest"
)

func main() {
	api := rest.New("", "")
	spread, err := api.GetSpread("ADAETH", 0)
	if err != nil {
		log.Fatalln(err)
	}
	log.Println(spread)

	t, err := api.Time()
	if err != nil {
		log.Fatalln(err)
	}
	log.Println(t)
}
