title: Best way to work with Real Time Data from local file
body: <p>I need to work with realtime data coming from a local file on the user computer. Analize it and display it in real time, using maps &amp; graphs.</p>
  <p>My target is to create an electron desktop app or something similar, so on the frontend I would use JS.
  To analize the data I want to use Python so, would be the simple Python backend and JS frontend.</p>
  <p>What is the best way to start this project? This are the options I have in my mind:</p>
  <ul>
  <li>Flask</li>
  <li>Simply using Python files and call them using child_process from JS</li>
  <li>Sockets</li>
  </ul>
  <p>Is there any better idea?</p>
