    Documentation

    This sdk makes use of the api version 2 of cryptomarket.

    Quick Start

    rest client

    const { Client } = require('cryptomarket')
    
    // instance a client
    let apiKey='AB32B3201'
    let api_secret='21b12401'
    let client = new Client(apiKey, api_secret)
    
    // get currencies
    let currencies = await client.getCurrencies()
    
    // get order books
    let orderBook = await client.getOrderBook('EOSETH')
    
    // get your account balances
    let accountBalance = await client.getAccountBalance()
    
    // get your trading balances
    let tradingBalance = await client.getTradingBalance()
    
    // move balance from account to trading
    let result = await client.transferMoneyFromAccountBalanceToTradingBalance('ETH', '3.2')
    
    // get your active orders
    let orders = await client.getActiveOrders('EOSETH')
    
    // create a new order
    let newOrder = await client.createOrder({'symbol':'EOSETH', 'side':'buy', 'quantity':'10', 'price':'10'})

    websocket client

    There are three websocket clients, one for public request (WSPublicClient), one for trading request (WSTradingClient) and one for the account requests (WSAccountClient).

    Clients work with promises

    Clients must be connected before any request. Authentication for WSTradingClient and WSAccountClient is automatic.

    const { WSPublicClient, WSTradingClient, WSAccountClient} = require('cryptomarket')
    
    let publicClient = new WSPublicClient()
    await publicClient.connect()
    
    // get currencies
    await publicClient.getCurrencies()
    
    let apiKey='AB32B3201'
    let apiSecret='21b12401'
    let tradingClient = new WSTradingClient(apiKey, apiSecret)
    
    await tradingClient.connect()
    
    // get your trading balance
    let balance = await tradingClient.getTradingBalance()
    
    // get your active orders
    let activeOrders = await tradingClient.getActiveOrders()
    
    await tradingClient.createOrder({
        clientOrderId:"qqwe123qwe", 
        symbol:'EOSETH', 
        side:'buy', 
        quantity:'10',
        price:'10'
    })
    
    let accountClient = new WSAccountClient(apiKey, apiSecret)
    await accountClient.connect()
    
    // get your account balance
    let accBalance = await accountCilent.getAccountBalance()

    subscriptions

    all subscriptions take a callback argument to call with each feed of the subscription

    // callback is for the subscription feed
    function callback(feed) {
        // handle feed
        console.log(feed)
    }
    
    await publicClient.subscribeToOrderBook('EOSETH', callabck)
    
    
    await accountClient.subscribeToTransactions(callback)

    error handling

    { CryptomarketSDKException, Client, WSPublicClient } = require('cryptomarket')
    // exceptions derive from the CryptomarketSDKException class.
    
    client = new Client()
    // catch a failed transaction
    try {
        order = client.createOrder({
            'symbol':'EOSETHH',  // non existant symbol
            'side':'sell',
            'quantity':'10', 
            'price':'10'})
    } catch (error) {
        console.log(error)
    }
    
    wsclient = new WSPublicClient()
    await wsclient.connect()
    
    // catch a missing argument
    try {
        await wsclient.subscribeToOrderbook('ETHBTC') // needs a callback
    } catch (error) {
        console.log(error)
    }
    
    // also catches forwarded errors from the cryptomarket exchange server
    try {
        let trades = await wsclient.getTrades("abcde", myCallback) // not a real symbol
    } catch (err) {
        console.log(err)
    }
