title: Is it possible to have progress bar for file uploads when using REST API?
body: <p>I use <code>base64</code> encoding for file uploads. The <code>REST API</code> is as below for file uploads:  </p>
  
  <pre><code>POST /users/:resourceid/files
  </code></pre>
  
  <p>Authentications are handled through <code>resourceid</code>. And the content of the <code>POST</code> request is files content in <code>base64</code> format.  </p>
  
  <p>Can I have progress bar for my file uploads? If no, then which path should I take to handle file uploads with progress bar?</p>
