Reagent video 20 Firebase Setup with Firebase 9.23.0 needs clj->js for config

[kentbull]

Using the latest, as of today, 9.23.0 version of Firebase with this course requires a slight change to wrap the config object in the clj->js function so that the firebase/initializeApp function can recognize the configuration object as a proper JSON object.

(ns giggin.fb.init
  (:require ["firebase/app" :as firebase]
            ["firebase/database"]
            ["firebase/auth"]))

(defn firebase-init
  []
  (let [config (clj->js {:apiKey "myapikey"
                         :authDomain "mydomain.firebaseapp.com"
                         :projectId "mydomain"
                         :storageBucket "mydomain.appspot.com"
                         :messagingSenderId "1234123412341234"
                         :appId "1:123412341234:web:1234123c41234c123c"
                         :measurementId "G-SD78DF8DDF8"})
        app (firebase/initializeApp config)]))

There are two ways to convert ClojureScript maps to JavaScript objects. You could use clj->js which is one way and a bit more heavier (it will also evaluate any code you have in the CLJS map and then there is #js {} which converts the thing without evaluating; when you have static properties, as in this example, it's advisable to use #js {} hope that helps.

Those two ways make sense. What was a problem for me was the video showing use of the config in firebase/initializeApp without showing Clj->js and thus was stuck on errors for a while.

the next video shows that, though first timers would be tripped up.
