I'm working with an Angular 2.0 project using this uploader.
I'm trying to show an alert to the user if they try to refresh or navigate away from the page when a file is uploading. I've found how to do display an error if an item is uploading by using an *ngIf = "item.isUploading," but I have not found any way to subscribe to the event in the controller.
Any ideas?

You could use different functions on the uploader, for example when a file is added:
this.uploader.onAfterAddingFile = () => this.isUploading = true;
and then when it completes you handle complete all:
this.uploader.onCompleteAll = () => this.isUploading = false;
Then you can show the alert based on the status of this.
