I'm not quite sure I'd go as far as calling React minimal, but yeah, there are definitely fairly light options here. Mithril is pretty classic as a "bare minimum framework" option. Vue can be used without any bundling/compilation steps as well, although I think that's less supported these days. I also quite like SolidJS - again, they encourage you to use the compiler, but you can also just use it with template literal strings and it should work just fine.
