title: As a developer, what can I run when chrome is closed and running in the background
body: <p>I was wondering what kinds of processes I can run when Chrome is closed and running in the background.</p>
  <p>For context, I created a chrome extension that was supposed to keep a socket.io connection open while chrome is closed and running in the background but after a few seconds, I noticed the connection was closed. This is because I was managing the socket connection in a service worker and service workers are stopped after some time when there's no activity.</p>
  <p>So my question is, besides just getting notifications from WebPush, what other things can be run in Chrome when it is closed and running in the background</p>
