cleaning up processes when ExtensionUnloaded

Dear ppro fellows,

I'm trying to kill processes spawned by my CEP panel after the panel is closed.

As specialists from this forum explained, to register the ExtensionUnloaded event from my CEP panel I need to have the invisibale custom CEP panel which starts when ppro starts. 

Therefore:

Frist: in manifest.xml I added the second invisible extension and added to it:

<StartOn>
    <Event>applicationActivate</Event>
    <Event>com.adobe.csxs.events.ApplicationActivate</Event>
</StartOn>

And indeed, as far as I understand, this invisible panel starts when ppro starts.

Second:

in my index.js of  the invisible panel I'm listening for an 

com.adobe.csxs.events.ExtensionUnloaded

event:

csInterface.addEventListener("com.adobe.csxs.events.ExtensionUnloaded", function(){
alert("Closed app");
});

 But then, strange thing happens. When I start my ppro 

the "com.adobe.csxs.events.ExtensionUnloaded" is triggered somehow right on the start and I see this alert "Closed app".

Of course, when I close my visible CEP this alert is triggered again. But how can I get rid of this thing on the ppro start?

Is it because when ppro starts it unloads some panels and this alert is triggered by another unrelated to my extension event?

If so, is it possible to catch the unload event from my visible panel (with my ID) only?

Yaroslav.

Check event data for information about what extension was unloaded.csInterface.addEventListener('com.adobe.csxs.events.ExtensionUnloaded', function(evt) { console.log(evt.data); });

I don't know if I do it proper way, but I just check it like this:csInterface.addEventListener('com.adobe.csxs.events.ExtensionUnloaded', function(evt) { var extID = "your.extension.id"; if (evt.data.indexOf(extID) > -1) { // your code } });

Thanks, Ivan!

That did help and illuminated things.

As I found out evt.data return literally this:

<ExtensionUnloadedEvent>
	<Id>com.adobe.ccx.start</Id>
	<ClosingType>4</ClosingType>
</ExtensionUnloadedEvent>

This Id is not, of course,  the Id of my application.

So in the function of event Listener I need to add additional condition: check extention Id.

My last question is how do you get Id from event.data. I tried: 

evt.data.attrubutes'Id');
evt.data.attr('Id');
evt.data.getAttribute('Id');

Nothing worked.

Yaroslav.

I have to implement the same behavior but this event fires only in

Premier pro 2019.  But in the Premier pro 2020 and Premier pro 2021 it doesn't. Doest it work for you in them? I also tried the next trick, 

const process = cep_node.process;

export function onExit(callback) {
  process.on('exit', callback);
  process.on('SIGINT', callback);
};

onExit(function() {
   cep.fs.writeFile("/tmp/123.txt", "exited");
});

 But it also doesn't work in some cases. For example, if there are no open projects this approach doesn't work too.
