I don't think you'd need a library around bootstrap?

I would write a clojure macro which can load and parse the json.

should I just convert the entire json into a clojure object

i was initially going to put the JSONs as a gist that I can GET using cljs-ajax (which I think can parse the JSON), but then I thought that it's probably even better if i can just import the JSON in the same source directory

You can, although the macros still needs to return valid clojurescript code. It might be easier to return (js->clj (.parse js/JSON "..."))

how do I import the JSON file in the first place?

(defmacro load-json [file]
  `(js->clj (.parse js/JSON ~(slurp file))))

☝️ is a more complete solution

But the idea is that you use the jvm to load the file as a string and parse the json in the javascript runtime via interop

You can also leverage if you want to load a file from the classpath, like in a jar 👌

(defmacro load-resource-json [file]
  `(js->clj (.parse js/JSON ~(slurp ( file)))))

if you're using shadow-cljs, you can just use shadow.resource/inline without creating your own slurp and worrying about compilation reload stuff yourself https://clojureverse.org/t/using-none-code-resources-in-cljs-builds/3745
