There are a couple Clojurescript interfaces to React: Om (https://github.com/omcljs/om) and Reagent (https://reagent-project.github.io/) are two I'm familiar with.

For an example of how a Clojurescript project would be built using these libraries, I'd recommend checking out re-frame: https://github.com/Day8/re-frame

Easy 3 step process:

1. Assuming you have leiningen installed, run `lein new figwheel hello-world -- --reagent` and follow the instructions in the output

2. Follow along with https://reagent-project.github.io/

3. Enjoy a nice, refreshing beverage.

One point about libraries: I would recommend starting up with Reagent, as it has a simple and fairly intuitive model, and then moving on to Rum, which allows you to do anything, while being small and elegant.

I do not recommend Om for starting.
