firebase emulators:start the `__/firebase/init.js` points at the web and not local eumulators

I have my Firebase stuff setup locally and the emulators work fine (I can get into the UI and everything) but when I access my webapp locally at http://localhost:5000/ and look at the contents of init.js all the variables point at the cloud datastore and stuff.

My unit tests will talk to the emulator by doing this:

var authenticatedApp = firebaseTesting.initializeTestApp({
    databaseName: "blahblah-d46ae",
    auth: { uid: "alice", email: "[e-mail]" }
})

beforeAll((done) => {
    //initFirebase();
    done()
})

afterAll((done) => {
    //firebase.database().goOffline();
    Promise.all(firebaseTesting.apps().map(app => {
        app.delete()
    })).finally(done)
})

How do I start the emulator so that init.js will point to everything locally (functions, database, etc…)?

@PaulRudin You can now opt-in to an emulated init.js by adding ?useEmulator=true flag, like so:

<script defer src="/__/firebase/init.js?useEmulator=true"></script>

For new projects initialized from the Firebase CLI, this flag will be automatically set for you in the generated public/index.html.

This flag has no effect in production Firebase Hosting and it only configures enabled and running emulators. If you want the Auth Emulator, please run firebase init emulators first and check it from the list.

This is still an issue, and now there’s an auth emulator, so presumably it should be possible to coax the emulator to do the right thing when running locally.
