This is where "react is a library, not a framework" kinda lets it have its cake and eat it too. preact is 4 kb, React + react dom is like 30 kb, but when I use it under commercial pressure to deliver it seems to climb into the megabytes. I'm working on a react native app right now that is a completely embarrassing 150 Mb. The experiment in no react, build UI from scratch every state change has stayed around 65 kb without much attention paid to bundle size, with 10 kB of that being a bunch of linear algebra and differential equation solving code and 50 kb of that a plotting library that's completely nonblocking for the rest of the app.
