Auth using Emulator with demo project

[Ticlext-Altihaf]

Describe the feature you would like to see

Is it possible to use Firebase Emulator with demo Firebase project, it would be useful for CI testing where the current setup require creating new Firebase project and issue service account.

https://firebase.google.com/docs/emulator-suite/connect_auth#choose_a_firebase_project

Example from using official Admin SDK for Node.js, it works without requiring internet connection or having Firebase project.
firebase emulators:start --project=demo-project

process.env.FIREBASE_AUTH_EMULATOR_HOST = "127.0.0.1:9099"
import { initializeApp } from 'firebase-admin/app';
import { getAuth } from 'firebase-admin/auth';

initializeApp({
    projectId: 'demo-project',
});

const newUserData = {
    email: Math.random()*10000 + '@example.com', // [email protected]
    emailVerified: false,
    phoneNumber: '+1' + Math.random()*10000000000, // +1XXXXXXXXXX
    password: 'secretPassword',
    displayName: 'John Doe',
    photoURL: 'http://www.example.com/12345678/photo.png',
    disabled: false,
};

const user = await getAuth().createUser(newUserData)

// Getting the ID token with signInWithPassword
let idToken = await fetch(`http://127.0.0.1:9099/identitytoolkit.googleapis.com/v1/accounts:signInWithPassword?key=random`, {
    method: 'POST',
    headers: {
        'Content-Type': 'application/json',
    },
    body: JSON.stringify({
        email: user.email,
        password: "secretPassword",
        returnSecureToken: true,
    }),
})

idToken = await idToken.json()
idToken = idToken.idToken

const userFromIdToken = await getAuth().verifyIdToken(idToken)

await getAuth().deleteUser(userFromIdToken.uid)

Yes, you can read about it here:

Uh.. I think you misunderstood me, I did read the docs I can't find the guide where I can use Firebase Demo Project, yes it work with Real Firebase Project.

The code, where in Node.js SDK it work without credentials.

        $request = CreateUser::new()
            ->withEmail($email)
            ->withPhoneNumber($phoneNumber)
            ->withClearTextPassword($password)
            ->withDisplayName($faker->name);


        $firebaseUser = Firebase::auth()->createUser($request);

Ah, I understand now, sorry for closing the issue so early 🙏🏻 (it's early here 😅)

I think this should be working, I'm running emulator tests with it, but seeing the demo- prefix... I've perhaps been doing it wrong the whole time 😬

firebase-php/.github/workflows/emulator-tests.yml

Line 71 in 393a751

FIREBASE_AUTH_EMULATOR_HOST: localhost:9099

I'll try to look into it as soon as I find the time, I'm currently working on the next major release for PHP 8.3, and I do have only limited time...

@jeromegamez Did you ever find a solution for this? I am running into a similar issue where verifyIdToken() is making calls to google apis even though I'm pointing to the Firebase Emulators.
