It's stuff like this that makes me want to scurry right back into the SRE/sysadmin space. Currently back in webdev after a few years out. I just feel like I'm being a pain in the arse to comment "could just write the HTML...?".

This very article loaded 2.49MB (uncompressed) over 30 requests. It's served using Next.js (it does actually load fine with JS disabled).

Ironically this is a great opportunity for the author to have made a stronger point. It could have gone beyond the abstract desire of "going back to basics" to perhaps demo reworking itself to be served using plain HTML and CSS without any big server-side frameworks.
