You have a lot of choice. Bulma is javascript-free, ant design with https://gitlab.com/synqrinus/syn-antd, styled component (check https://www.jacekschae.com/learn-re-frame-free)

antd is very nice but it seems really heavy

All the JS component libraries are going to be quite heavy as you don't get dead code elimination for JS libs. My choice is usually to just implement all the components in Cljs and style with SASS/LESS.

Bulma seems like OK CSS framework if you don't want to start from scratch

You then get some annoying dependencies

I'm looking to upgrade my React dependency. Is reagent compatible with React 16.9?

Looks like the package.json in Reagent's repo has 16.9 so assuming that means it's compatible! https://github.com/reagent-project/reagent/blob/3b10c426c1003ba9bc93e8c1e3c3d13a73158cec/package.json#L6-L7

Yeah, you’re good 🙂

Although I found navigation easier with re-frame
