I have no idea about that but if the figures you’re providing are correct it’s pretty obvious the answer is that they did it wrong. There is nothing in the web component API that would require 100+ requests nor several MB of JS, especially when you’re in control of every step in the process!

This is just not true.

Why does it need 100+ requests and over a megabyte of JS then?

Edit: when it was "unveiled" the sum total of JS was 178 requests totaling 1.37 MB: https://x.com/dmitriid/status/1777404560316707052

I don't know, but it only loads one copy of Lit.

Thank you, good to know
