Question

I have configured PHP to send me mails whenever there is an error. I would like to do the same with Javascript.

Also given the fact that this will be client side it is open to abuse.

What are good ways to get notified by mail when JS breaks in a web application?

Update:

Just to give some perspective, i usually load several js files including libraries (most of the time jQuery).

You can listen to the global onError event.

Note that you need to make sure it doesn’t loop infinitely when it raises an error.

<script type="text/javascript">
var handlingError = false;

window.onerror = function() {
   if(handlingError) return;
   handlingError = true;

   // process error

   handlingError = false;
};
</script>
