firebase.config() exists in functions but empty when called from webapp

[anandrishabh1]

[REQUIRED] Environment info

firebase-tools:
8.4.3

Platform:
macOS

[REQUIRED] Test case

1. Set a function config on the local machine:
   firebase functions:config:set app.environment="prd"

2. Deploy functions and check if the config is set by logging functions.config()
   

3. console.log(functions.config()) before firebase.initializeApp in webapp:
   
   Output is an empty dictionary

[REQUIRED] Steps to reproduce

Same as above

[REQUIRED] Expected behavior

Functions.config() should return the set config in order to change the firebase config based on project that webapp is deployed in order to achieve staging/prod/testing environment differentiation.

[REQUIRED] Actual behavior

functions.config() is an empty dictionary which leads to a loss of access to app.environment resulting in no control over differentiation between firebase environments

@anandrishabh1 when you say "in webapp" do you mean from a website using the Firebase JS SDK? If so that's the intended behavior, functions.config() is only available in the Cloud Functions environment, it uses the Cloud Runtime Configuration API.

If you want config for your web app, try Remote Config:
https://firebase.google.com/docs/remote-config/use-config-web

Closing this as it doesn't seem like it's a Firebase CLI issue.
