Node Bittrex API

Node Bittrex API is an asynchronous node.js library for the Bittrex API - https://bittrex.com/. The Bittrex API data can be received either as a GET request or via Websockets API.

Documentation for the Bittrex API: https://bittrex.com/Home/Api

This Library is licensed under the MIT license.

Contributors

Thanks go to the people who have contributed code to this Library.

Before you start

This is just a quick reminder that you are handling coins with this library (and thus real money), so, understand the situation as much as possible and make everything to prevent losing them.

Here is a small checklist you should go through before you start:

  • Make sure you don't give your api key more rights as absolutely necessary - for first testing READ INFO alone should be enough! (bittrex.com under: Settings/API Keys)

bittrex_ap_keys_control

  • make sure to understand the API Key permissions
    1. READ INFO - Allows you to read private details such as open orders, order history, balances, etc
    2. TRADE LIMIT - Allows you to create/cancel trade limit buy/sell orders
    3. TRADE MARKET - allows you to create/cancel market buy/sell orders
    4. WITHDRAW - Allows you to withdraw to another address
  • Make use of the Bittrex IP Whitelist as also the Withdrawal Whitelist features
  • Do not ever commit your API Keys to GitHub or expose them under any circumstances!

Quick start

$ npm install node.bittrex.api
var bittrex = require('node.bittrex.api');
bittrex.options({
  'apikey' : API_KEY,
  'apisecret' : API_SECRET,
});
bittrex.getmarketsummaries( function( data, err ) {
  if (err) {
    return console.error(err);
  }
  for( var i in data.result ) {
    bittrex.getticker( { market : data.result[i].MarketName }, function( ticker ) {
      console.log( ticker );
    });
  }
});

Advanced start

fetch the project via git:

$ git clone https://github.com/dparlevliet/node.bittrex.api.git

then meet the package dependencies:

$ cd node-bittrex-api/
$ npm install

include node.bittrex.api.js into your project:

var bittrex = require('./node.bittrex.api.js');
configure
bittrex.options({
  'apikey' : API_KEY,
  'apisecret' : API_SECRET,
  'verbose' : true,
  'cleartext' : false
});

By default the returned data is an object, in order to get clear text you have to add the option cleartext (streams will always return text):

'cleartext' : true

The baseUrl itself can also be set via options

'baseUrl' : 'https://bittrex.com/api/v1',
'baseUrlv2' : 'https://bittrex.com/Api/v2.0',

Change the callbacks arguments sequence

'inverse_callback_arguments' : true,

This simply changes the sequence in which the arguments are passed, instead of e.g.:

getmarkethistory({market : 'USDT-BTC'}, function(data, error) {});

you'll get the reversed order:

getmarkethistory({market : 'USDT-BTC'}, function(error, data) {});

Websockets

Basic example

bittrex.websockets.client(function() {
  console.log('Websocket connected');
  bittrex.websockets.subscribe(['BTC-ETH'], function(data) {
    if (data.M === 'updateExchangeState') {
      data.A.forEach(function(data_for) {
        console.log('Market Update for '+ data_for.MarketName, data_for);
      });
    }
  });
});

Basic example with event emitters

bittrex.options({
  websockets: {
    onConnect: function() {
      console.log('Websocket connected');
      bittrex.websockets.subscribe(['BTC-ETH'], function(data) {
        if (data.M === 'updateExchangeState') {
          data.A.forEach(function(data_for) {
            console.log('Market Update for '+ data_for.MarketName, data_for);
          });
        }
      });
    },
    onDisconnect: function() {
      console.log('Websocket disconnected');
    }
  }
});
 
var websocketClient;
bittrex.websockets.client(function(client) {
  websocketClient = client;
});

Available methods

All of these methods will build a websocket client and attempt a connection if you have not run websockets.client yourself. See examples/ for a better understanding.

websockets.listen

bittrex.websockets.listen(function(data, client) {
  if (data.M === 'updateSummaryState') {
    data.A.forEach(function(data_for) {
      data_for.Deltas.forEach(function(marketsDelta) {
        console.log('Ticker Update for '+ marketsDelta.MarketName, marketsDelta);
      });
    });
  }
});

websockets.subscribe

bittrex.websockets.subscribe(['BTC-ETH','BTC-SC','BTC-ZEN'], function(data, client) {
  if (data.M === 'updateExchangeState') {
    data.A.forEach(function(data_for) {
      console.log('Market Update for '+ data_for.MarketName, data_for);
    });
  }
});

Websocket serviceHandlers example

You can override the libraries logic for the following events. Note, this will replace the libraries logic.

websocketClient.serviceHandlers.reconnecting = function (message) {
  return true; // set to true stops reconnect/retrying
}
 
websocketClient.serviceHandlers.messageReceived = function (message) {
  console.log(message); // the messages received must be parsed as json first e.g. via jsonic(message.utf8Data)
}

all possible serviceHandlers

bound: function() { console.log("Websocket bound"); },
connectFailed: function(error) { console.log("Websocket connectFailed: ", error); },
connected: function(connection) { console.log("Websocket connected"); },
disconnected: function() { console.log("Websocket disconnected"); },
onerror: function (error) { console.log("Websocket onerror: ", error); },
messageReceived: function (message) { console.log("Websocket messageReceived: ", message); return false; },
bindingError: function (error) { console.log("Websocket bindingError: ", error); },
connectionLost: function (error) { console.log("Connection Lost: ", error); },
reconnecting: function (retry { inital: true/false, count: 0} ) {
  console.log("Websocket Retrying: ", retry);
  //return retry.count >= 3; // cancel retry true
  return true;
}

Streams

Streams have been removed

Examples

After configuration you can use the object right away: example #1

bittrex.getmarketsummaries( function( data, err ) {
  if (err) {
    return console.error(err);
  }
  for( var i in data.result ) {
    bittrex.getticker( { market : data.result[i].MarketName }, function( ticker ) {
      console.log( ticker );
    });
  }
});

example #2

bittrex.getbalance({ currency : 'BTC' }, function( data, err ) {
  if (err) {
    return console.error(err);
  }
  console.log( data );
});

Libraries

Websockets depends on the following npm packages:

Other libraries utilized:

For HmacSHA512 this package is using a part of Googles Crypto.js (the node crypt package could not provide any appropriate result).

Error examples

Example of request/domain based errors (not Bittrex API error)

Methods

Optional parameters may have to be looked up at https://bittrex.com/Home/Api.

It may happen that some Bittrex API methods are missing, also they could have been forgotten in the documentation. In this case, if this strikes you, feel free to open a issue or send me a pull request.

Also: the method sendCustomRequest enables completely custom requests, regardless the specific API methods.

sendCustomRequest
  • url String
  • callback Function
  • credentials Boolean optional whether the credentials should be applied to the request/stream or not, default is set to false.

example #1

var url = 'https://bittrex.com/api/v1.1/public/getticker?market=BTC-LTC';
bittrex.sendCustomRequest( url, function( data, err ) {
  console.log( data );
});

example #2 (credentials applied to request/stream)

bittrex.sendCustomRequest( 'https://bittrex.com/api/v1.1/account/getbalances?currency=BTC', function( data, err ) {
  console.log( data );
}, true );
 
will result in (the Header is being set too):

Testing

Installing test gear

npm install --only=dev

Running all tests

npm test tests

or individually

npm test tests/public.js
npm test tests/private.js
Testing private methods

Testing private method endpoints requires an api key/secret which should be installed in to tests/config.json - you will find an example file in tests/config_example.json.

cp tests/tests_example.json tests/config.json
vim tests/config.json
