poloniex.js

An (unofficial) Node.js API client for the Poloniex cryptocurrency exchange.

The client supports both public (unauthenticated) and private (authenticated) calls to the Poloniex API.

For private calls, the user secret is never exposed to other parts of the program or over the Web. The user key is sent as a header to the API, along with a signed request.

Repo home: github.com/premasagar/poloniex.js

License

MIT, open source. See LICENSE file.

Install via NPM

npm install poloniex.js

Or clone from GitHub

git clone https://github.com/premasagar/poloniex.js.git
cd poloniex
npm install

Or download the latest zip

Require as a module

In your app, require the module:

var Poloniex = require('poloniex.js');

If not installed via NPM, then provide the path to lib/poloniex.js

Temporary certificate workaround

In the past, the API server's certficate was rejected. This was presumably a temporary issue and was reported to Poloniex and fixed. Should the issue come up again, the line below is a temporary workaround. First try using the client without this.

Poloniex.STRICT_SSL = false;  // this workaround shouldn't be necessary

Create an instance of the client

If only public API calls are needed, then no API key or secret is required:

var poloniex = new Poloniex();

Or, to use Poloniex's trading API, your API key and secret must be provided:

var poloniex = new Poloniex('API_KEY', 'API_SECRET');

Make API calls

All Poloniex API methods are supported (with some name changes to avoid naming collisions). All methods require a callback function.

The callback is passed two arguments:

  1. An error object, or null if the API request was successful
  2. A data object, the response from the API

For the most up-to-date API documentation, see poloniex.com/api.
