title: How can I serve static files with 404 redirection by PM2?
body: <p>I already know that there is a simple command to serve static folder by PM2:</p>
  
  <pre><code>pm2 serve &lt;path&gt; &lt;port&gt;
  </code></pre>
  
  <p>But how can I add 404 redirection to it? e.g. redirect to <code>404.html</code> while that happends. Can't find that on Google &amp; PM2 doc.</p>
