// N.B. keep these safe.  don't commit to source control etc...
var apiKey = '<your-api-key>';
var apiSecret = '<your-api-secret>';

const  valrClient = new ValrV1RestClient({ apiKey, apiSecret })
valrClient

    .getBalances()
        .then((balance) => console.log(balance))

var valrWsTradeClient = new ValrV1WsClient(ValrV1WsClient.WSPATHS.TRADE, { apiKey, apiSecret })
valrWsTradeClient.connect();

valrWsTradeClient.on('connected', () => console.log('TRADE:', 'connected'));

valrWsTradeClient.on('message', (data) => {
    if (data.type == 'AUTHENTICATED') {
        valrWsTradeClient.subscribe(ValrV1WsClient.TRADE_SUBSCRIPTIONS.AGGREGATED_ORDERBOOK_UPDATE, 'BTCZAR');
    } else if (data.type == ValrV1WsClient.TRADE_SUBSCRIPTIONS.AGGREGATED_ORDERBOOK_UPDATE) {
        console.log('TRADE OrderBook Updated:', util.inspect(data, { depth: 99, colors: true }));
    } else {
        console.log(data);
    }
});

valrWsTradeClient.on('error', (err) => console.log('TRADE:', err));
valrWsTradeClient.on('close', (code, reason) => console.log('TRADE:', code, reason));
valrWsTradeClient.on('disconnected', () => console.log('TRADE:', 'disconnected'));
