mark resource timing

[ronag]

Does node have something similar to https://w3c.github.io/resource-timing/#dfn-mark-resource-timing which would make sense to report fetch info to?

undici/lib/fetch/index.js

Lines 207 to 213 in 3d2dbc7

	markResourceTiming(timingInfo, originalURL, initiatorType, global, cacheState)
	}
	// https://w3c.github.io/resource-timing/#dfn-mark-resource-timing
	function markResourceTiming () {
	// TODO
	}

This would connect to perf_hooks but will need some additions. We have PerformanceEntry but no PerformanceResourceTiming yet. I don't think it would be difficult to add though. 🤔

[jasnell]

It's certainly doable. We'll need to expose a public API for publishing custom performance entries. Not unreasonable at all.

[jasnell]

I should be able to carve out some time next week to see what we need in node.js to make this a bit more feasible.

FYI I'm working on that in Node.js core. Planning a PR in Node.js in the next coming days.

FYI: PerformanceResourceTiming was just merged into master and it will be released next Tuesday on v18.2.

@Trott I think this issue doesn't need to be closed because undici.fetch doesn't use it yet.

I didn't manually close it. It got closed because of the "Fixes:" line in the commit message. Feel free to re-open or whatever you want to do with it. I have no opinion at all.
