Creating an nbb google cloud function

All you need to do to get nbb running on GCP Cloud Functions is the following:

package.json:

{
    "type": "module",
    "scripts": {
        "start": "functions-framework --target=hello"
    },
    "main": "index.mjs",
    "dependencies": {
        "nbb": "~1.2.174",
        "@google-cloud/functions-framework": "~3.2.0"
    }
}

index.mjs:

import { loadFile } from 'nbb';

const { hello } = await loadFile('./hello.cljs');

export { hello }

hello.cljs:

(ns hello)

(defn hello [req res]
  (js/console.log req)
  (.send res "hello world"))

;; export
#js {:hello hello}

Then deploy the function with:

$ gcloud functions deploy hello --runtime nodejs20 --trigger-http
