title: TCP sockets and file manipulation in Node.js
body: <p>I am new to Node.js and I have 2 questions about it:</p>
  
  <ul>
  <li>Can you create regular TCP sockets on the server's side?</li>
  <li>Is it possible to read/write to a file on the server's side?</li>
  </ul>
  
  <p>That's all. Both of these are critical for putting my program on the web.</p>
