Cloud Functions

Environment Var and Config
Function Environment variables is essentially using this beta feature from GCP: https://cloud.google.com/deployment-manager/runtime-configurator/set-and-get-variables​
​Using Environment Variables see also Environment configuration​

To set in firebase environment do 
firebase functions:config:set aws.aws_access_key_id="XXXX" aws.aws_scret_access_key="XXXX"
Using env var Locally
For this to run locally:
firebase functions:config:get > .runtimeconfig.json in functions 
folder, also add to .gitignore 
See instructions in their docs.

Storage Triggers
Firestore triggers https://firebase.google.com/docs/functions/firestore-events​
Since you cannot configure a function to be triggered by subdirectories. It's only possible to listen to the entire bucket. If you have a trigger based on Bucket, the recommendation is to create a new, separate bucket so that you are not triggered every time a file changes in the Bucket.
1.Create a new bucket
2.Update your Functions environment config with new bucket name
3.Call the functions.config() to get the specified bucket name
You can do environments for Functions:
$ firebase -P dev functions:config:set storage.bucket="dev-digital-paper-edit"
> ✔  Functions config updated.
​
$ firebase -P dev functions:config:get
> {
    "storage": {
      "bucket": "dev-digital-paper-edit"
    }
  }
$ firebase -P prod functions:config:get
> {}
And then subsequently in a Function you'd use the config like so:
const functions = require("firebase-functions");
const BucketFunctions = functions.storage.object(
 functions.config().storage.bucket
);
Caveat
A big caveat here - you don't have a document anywhere in your repo that tells you what this is. You need to be logged in into firebase and run the above 
firebase -P dev functions:config:get
command to know what this is.
