Any way to communicate request progress to swr?

[ephys]

Hello :)

Is there any plans to let us pass the progression percentage of the current fetch operation to useSWR?

Maybe something like

useSWR(
	'/big-dataset',
	(emitProgress) => /* fetch & call emitProgress when new data is loaded */,
	{ trackProgress: true },
);

This would allow us to use determinate progress indicators :)

Thanks!

Why not handling that inside fetcher? 😄

const [progress, emitProgress] = useState(0)
useSWR('/big-dataset', url => fetch(url, emitProgress))

Or you can build your own abstraction around that (like a custom hook useSWRWithProgress).

I think one of the most important feature of SWR is tiny, but highly flexible (isolated from the actual fetch handler).

Related to #129.

That solution works for me, thanks :)
