Ability to interrupt a download?

[pandaiolo]

Hey there, first of all, thanks for making this library available 🙏

I have been using it for some time and notice that when a large zip download is started, it seems that it cannot stop?

• If I close the tab and open the app in another tab, and I see the files continuing to be downloaded in the network tab.
• Simply interrupting the download in Google Chrome does not stop the fetching either

Is there a way to:

1. Stop the download automatically under some circumstances (user cancelled download)
2. Stop the download programmatically (calling a method or sending a message to the worker?)

If the service worker stays running then I suppose that it would indeed continue to download with the current setup. Shouldn't be too hard to modify that code to add a "stop" trigger that exits the loop after the current chunk. If you do, please submit a PR and I'd be happy to upstream.

Thank you

My 1st point above seems more like a browser bug? - with the underlying stream not being canceled when user interrupts the download. Here are some related Chromium bug reports:
