Downloads all docs in a Firestore collection and stores as a JSON file -- command-line JavaScript/node
/**
* get_firestore_collection_as_json.js
*
* This code is a "node script" used to fetch all documents from a Firestore collection,
* either in "the cloud" or the emulator, and write them to a file as JSON.
*
* The script is a "client app", so it logs in with Firebase Auth using email/password from the variable USER1.
* This USER1 user ([email protected]) must exist in your Firebase project and have read access
* to the collection(s) you are populating. You can create that account via
* Firebase Console >> Authentication.
