hollaex-node-lib

Nodejs library for HollaEx Kit enabled exchanges.

This library is specifically for end users and traders to connect to HollaEx Kit exchanges. It connects to HollaEx Pro by default.

Usage

const hollaex = require('hollaex-node-lib');

const client = new hollaex();

You can pass custom apiURL, wsURL and baseURL of the HollaEx-Enabled exchange to connect to. apiURL is https://api.hollaex.com for HollaEx Pro and for your custom exchange it would be something like https://myexchange.com/api. wsURL is the websocket URL for the socket connection and you should pass your stream URL. For HollaEx Pro it is wss://api.hollaex.com/stream and for your exchange it would be something like wss://myexchange.com/stream. baseURL is not required and it is set by default to /v2 unless you need to connect to an older version of HollaEx.

You can also pass your apiKey and apiSecret generated from the HollaEx-Enabled exchange to use private requests that require authentication. For public endpoints apiKey and apiSecret are not required.

const client = new hollaex({
	apiURL: '<EXCHANGE_API_URL>',
	wsURL: '<EXCHANGE_WS_URL>',
	apiKey: '<MY_API_KEY>',
	apiSecret: '<MY_API_SECRET>'
});

You can also pass the field apiExpiresAfter which is the length of time in seconds each request is valid for. The default value is 60.

Example:

const client = new hollaex({
	apiURL: '<EXCHANGE_API_URL>',
	wsURL: '<EXCHANGE_API_URL>',
	apiKey: '<MY_API_KEY>',
	apiSecret: '<MY_API_SECRET>'
});

client
	.getTicker('xht-usdt')
	.then((res) => {
		console.log('The volume is: ', res.volume);
	})
	.catch((err) => {
		console.log(err);
	});

client
	.getTrades({ symbol: 'xht-usdt' })
	.then((res) => {
		console.log('Public trades: ', res);
	})
	.catch((err) => {
		console.log(err);
	});

Websocket

Functions

You can connect and subscribe to different websocket channels for realtime updates.

To connect, use the connect function with the channels you want to subscribe to in an array as the parameter. The connection will reconnect on it's own unless you call disconnect.

client.connect(['orderbook', 'trade']);

To disconnect the websocket, call disconnect.

client.disconnect();

To subscribe to more channels after connection, use subscribe.

client.subscribe(['order', 'wallet']);

To unsubscribe from channels after connection, use unsubscribe.

client.unsubscribe(['orderbook']);

Channels

Here is the list of channels you can subscribe to:

• orderbook (Available publicly)
• trade (Available publicly)
• order (Only available with authentication. Receive order updates)
• usertrade (Only available with authentication. Receive user trades)
• wallet (Only available with authentication. Receive balance updates)
• deposit (Only available with authentication. Receive deposit notifications)
• withdrawal (Only available with authentication. Receive withdrawal notifications)
• admin (Only available with authentication for the exchange administrator. Receive exchange operations such as deposits and withdrawals of all users)

For public channels (orderbook, trade), you can subscribe to specific symbols as follows: orderbook:xht-usdt, trade:xht-usdt. Not passing a symbol will subscribe to all symbols.

Events

After connecting to the websocket, you can listen for events coming from the server by using the on function for the ws property of the client. The events available are default websocket events e.g. message, open, close, error, unexpected-response, etc.

client.ws.on('message', (data) => {
	data = JSON.parse(data);
	console.log(data);
});

These are exapmles of data responses from the server.
