I'm making a POC with https://github.com/maxdome/swagger-combine. I tried to run the following

(ns mario.combine
    (:require ["swagger-combine" :as swagger-combine]
                    [promesa.core :as p]))

(def combine-try
  (-> (swagger-combine "swaggers/dummy/combined-swaggers.json")
      (p/handle  (fn [res _err]
                   (-> res js/JSON.stringify js/console.log)))))````

I got the following error indicating that the js module cannot be found when loading `combine-try`, but loading "swagger-combine" on REPL seems to be successful.

```java.lang.AssertionError
: 
"Assert failed: (symbol? module)"

In Shadow-CLJS (ClojureScript), you can't evaluate the namespace if it contains node/browser/string requires because Shadow becomes confused. I don't know if this is a ClojureScript issue or Shadow one. You can reproduce the issue with a cljs-repl by doing the following code on the REPL:

(let [res
      (ns mario.combine
          (:require ["swagger-combine" :as swagger-combine]
                    [promesa.core :as p]))

(def combine-try
  (-> (swagger-combine "swaggers/dummy/combined-swaggers.json")
      (p/handle  (fn [res _err]
                   (-> res js/JSON.stringify js/console.log)))))

The fix is simply do not evaluate the ns form - ever. On shadow-cljs, hot-reload plays a significant role so everytime you save your file, your namespace is already up-to-date - no need to re-eval it 😃
