What's the deal with useFirestoreEmulator?

[akauppi]

I want to set up Firestore emulator, using the @exp API.

Docs Common use cases show using initializeFirestore. But there's a useFirestoreEmulator as well.

Should I use one, either one, or both?

For the emulator functions, this was a conscious decision to have free-floating functions to configure the emulator (so that these don't impact the bundle size when you're not using the emulator). So you'd use (initializeFirestore OR getFirestore) AND useFirestoreEmulator. As with the old version, make sure the emulator function is called before the library is used.

For example:

import { getFirestore, useFirestoreEmulator } from 'firebase/firestore';
const firestore = getFirestore(app);
useFirestoreEmulator(firestore, 'localhost', 8080);

(The difference between initializeFeature and getFeature is that the former allows for more custom configuration of dependencies, whereas the latter pulls in the normal platform-specific defaults).

As for IDE highlighting issue, I'm not sure about that

Your code is how I initially wrote it. Then I noticed the docs showing another way.

Thanks for the confirmation. Should I open a different discussion about the IDE highlight - looks like a packaging bug to me.

Thanks for pointing that out; we need to update the docs. The API was in flux for a little bit there.

Yeah please open up a new discussion specifically for the IDE highlighting :)
