Is there any event listener/callback for file download in CollectionFS?

Question

I'm using the CollectionFS to store and download files from my application

<a href="{{this.url download=true}}">Download</a>

And I want to execute a server-side function when the file is downloaded (without using jQuery because it's not really credible and can be bypassed).

I was wondering if there's any undocumented function / workaround to execute my code/hook when there's a download, something like this:

filesCollection.on('download', function(fileObject){
  // do stuff
});

Thanks

What you're looking for is called a transformRead in CollectionFS. It's the mirror function of transformWrite. Documentation.
