My question was firstly asked on SO, but I had a second thought and as discussed on chat, I came back home on CR.
This simple script will allow me to check for a specific opened port on a list of domains that I own. Instead of manually doing this check, I found Python a pretty good idea...

const styles = el.style;
el.className += 'drag';
styles.left = options.x + 'px';
styles.top = options.y + 'px';
styles.width = options.width + 'px';
