I hereby claim:

To claim this, I am signing this object:

	const flatten = require('./flatten');

	describe('flatten', () => {
	it('should flatten deeply nested arrays of integers', () => {
	const arrays = [1, 2, 3, [4, 5, 6, [7, 8, 9], [10, 11, 12]]]
	const expected = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12];

	expect(flatten(arrays)).toEqual(expected);
	});
	});

	const getCustomClaimsByEmail = require('../utilities/get-custom-claims-by-email');
	const setCustomClaims = require('../utilities/set-custom-claims');

	module.exports = ({ admin, environment }) => user => {
	const db = admin.firestore();
	const usersCollection = db.collection(environment.schema.users);
	const customClaimsRef = admin.database().ref(environment.schema.customClaims);
	const auth = admin.auth();
	const email = extractEmailFromUser(user);

	if (typeof window.FirebaseMixin == 'undefined') {
	window.FirebaseMixin = superclass => {
	if (!superclass) {
	superclass = class Superclass {};
	}

	return class extends superclass {
	constructor() {
	super();
	this.__firebaseMixinInit();

	// Good
	exports.sendEmail = functions.auth.user().onCreate(event => {
	const mailgun = require('mailgun-js');
	// ...
	});


	// Not As Awesome
	const mailgun = require('mailgun-js');
	exports.sendEmail = functions.auth.user().onCreate(event => {

	const function = require('firebase-functions');

	functions.database.ref('queues/login/{uid}').onWrite(event => {
	const config = functions.config();
	// functions.config() returns your environment variables.
	// In this case I have an array of my admin users' email addresses in accessControlLists.adminUsers
	// It looks like ['chris@chrisesplin.com', 'some-other-admin@chrisesplin.com']
	const adminUsersString = config.['access-control-lists']['admin-users'];
	const adminUsers = adminUsersString.split(',');
	const user = event.data.val();

	// Client-side code, in my case a web browser
	firebase.auth().onAuthStateChanged(function (user) {
	this.user = user; // Set my local copy of the 'user' object
	if (user) {
	this.displayName = user.displayName;
	this.photoURL = user.photoURL;
	var userRef = firebase.database().ref('queues/login').child(user.uid);

	userRef.remove()
	.then(function () {

	functions.auth.user().onCreate(event => {
	const functions = require('firebase-functions');
	const admin = require('firebase-admin');
	const config = functions.config();

	admin.initializeApp(config.firebase);

	const user = event.data;
	const userRef = admin.database().ref('/users').child(user.uid);
