title: Generating an SAS Token on client side (using AngularJS) to upload a blob to Microsoft Azure
body: <p>I currently have a site built with HTML/Javascript and AngularJS.  I am having a hard time uploading an image to Azure as a blob because I do not know how I can generate an SAS Token. I am using an upload service found here <a href="https://github.com/kinstephen/angular-azure-blob-upload" rel="nofollow">https://github.com/kinstephen/angular-azure-blob-upload</a> but require an SAS Token to get the file to upload. </p>
  
  <p>Almost every example I find uses a backend to generate the token but this app is using AngularJS as its backend.</p>
