I could not keep my eyes of off readme.com's beautiful API-metrics - so I did what any other (in)sane person would do, and re-created it with svelte!
As for now, it's simply using a setTimeout to tell when a request has finished. Though, in the future, I'd love to use web-sockets - moreover actually listen for when a request has finished.
This might not be possible on vercel alone, but could be if I decide to couple on a datastore - e.g. redis?
