I suggest using Reagent, but if you want direct ClojureScript on top of React without any other library, then I think your best bet is to look closely at ClojureScript interop with Javascript.
There are even higher level libraries/frameworks like Re-frame (runs on top of Reagent), but I suspect that's not what you want based on your question.
Reagent is a minimalist wrapper to React. I believe it will make your life easier. At least look at the first link above and checkout how to create React components in Reagent.
