node.js exception handling server

Question

Is there a exception manager for node.js that can do this:

If an expection gets thrown replace a file on server and change something in the database (eg. roll back to he version before) and restart the server. I know that there are managers like "pm2" oder "forever" but can they do something like this?

?

Generally servers handle exceptions at the top level (for example if it is a http server then by returning 500). Otherwise they would crash each time an exception occures. So whatever you are trying to achieve you have to do that inside the code. — freakish

You can handle global exceptions like so:

process.on('uncaughtException', (err) => {  
  // your logic here
});
