title: Send Data from chrome extension to Node.js
body: <p>I have created a simple Chrome extension which stores all a few clicks on some Z webpage in my content_script. So, I want to know a way to send this data (json) to my node.js file (lets say /start).</p>
  
  <p>How exactly to go about this? starting from sending data from the extension through ajax AND receiving this data in my /start router js file?</p>
  
  <p>Any help appreciated. Thanks.</p>
