Download and Upload Progress Indicator/Tracking

[nickchomey]

It would be very neat if wretch could incorporate an easy to use API for tracking download and upload progress, like ky and axios can do.

Upload progress was previously not possible, but it seems this should now be possible with Chromium versions > 105.

fetch() upload streaming - Chrome Platform Status (chromestatus.com)

Here's an example implementation: https://stackoverflow.com/a/52860605/19510854

Hey @nickchomey,

Indeed, I'll look into it!

I'm not sure it's possible to monitor upload progress though, only download progress (fetch limitation).
Replied too fast sorry.

@nickchomey

I just added an addon to monitor the download progress with this commit: 2bae524

Regarding upload progress, it seems to be more complicated unfortunately.
Both Request.body and/or uploading the body as a stream do not seem to be widely supported yet:

• Streaming upload whatwg/fetch#1438
• https://developer.mozilla.org/en-US/docs/Web/API/Request/body#browser_compatibility

So for the moment it does not seem reasonable to implement it.
I will reopen this issue when the time is right 😉.

Cool stuff, thanks for the update and links! That was an enlightening read, even if I have little technical appreciation for it all. I look forward to it becoming a reality someday, in general and in wretch.
