ClojureScript: Get a Hashmap of js/window

In ClojureScript I'm trying to convert (not recursively, only the lowest level) of the global window object into a hashmap.

Usually, if js-objects are not constructed by Object, the following interop helps:

(defn jsx->clj [js-o]
  (reduce (fn [m v]
            (assoc m (keyword v) (aget js-o v)))
          {} (.keys js/Object js-o)))

However, if I apply this to js/window I'm getting errors:

#object[TypeError TypeError: Cannot convert a Symbol value to a string]
[...]

Has anyone made experiences with this?

Solution

  • The mysterious error is not in your code but happens when the repl attempts to output the result.

    Evaluate js/cljs in the repl to replicate, as this is the culprit.(def foo (doall (jsx->clj js/window))) works without a hitch except now the error appears if you evaluate (pr foo) in the repl or just foo by itself.
