title: Upload file to google drive with javascript from anonymous user
body: <p>I want to allow my anonymous website's visitors to upload files to Google Drive on behalf of my application. In a new app console I spotted some sort of Browser key, can I use it to reach my goal?
  Or maybe there are some other ways of doing this by using Cloud Storage or something?</p>
  
  <p>I don't want to involve server-side authentication, I need a pure Javascript solution.</p>
  
  <p>PS: This article (<a href="https://developers.google.com/drive/quickstart-js" rel="noreferrer">https://developers.google.com/drive/quickstart-js</a>) doesn't help, since it requires my users to have Google Account.</p>
