Retrieve parse progress

[jonybekov]

Is it possible to retrieve progress information of parsing?
So that we can display some loading progress (10/500) to the user?

Yes, I personally feel the need for this kind of functionality from time to time as well. I’ve been considering adding such an option, but I’m not sure it should be part of the parser itself.

Usually, I solve this by wrapping the source (for example, a stream) with a handler that tracks how much data has been processed. That’s where I emit notifications to display the progress.

For example, like this: https://github.com/discoveryjs/jora-cli/blob/master/src/read-from-stream.js#L23
