Windows Azure Storage library for Node.js

A simple implementation of Windows Azure Storage API for Node.js

Installation

waz-storage-js depends on querystring (>= v0.0.1) and xml2js (>= v0.1.9).

To install via npm

npm install waz-storage-js

Examples

Initial Setup

var waz = waz.establishConnection({ 
		accountName: 'your_account_name'
		, accountKey: 'your_key', 
		, useSsl: false 
	  });
