Closing Stream in provided demo

[robot-ranger]

what is the proper way to abort/close the stream in the demo code? In our react app, I would like to close the stream when the components un-mount (ex user navigates away).

I tried calling controller.abort(). I get an AbortError exception, which i suppose is expected, but it seems like data continues to arrive.

I continue getting the console print on this line:

cppagent/demo/twin/lib/mtconnect/protocol.js

Line 119 in d6bc710

console.log("Read " + text.length + " bytes");

Even after running controller.abort and navigating away. It doesnt appear to have actually aborted?

I have verified that controller.abort() has run, i have set a break point and verified aborted=true. I also have a log print console.log("component unmount and cleanup")

questioning if i am not using the abort controller correctly

@wsobel - any input here? I cant seem to figure out how to close a running stream programmatically.

It looks like the protocol may keep running. We may need to put a flag in to stop the loop and exit streaming.
