Describe the problem

Connecting to the different emulators have different syntax. It works one way to connect to the Auth emulator, another to connect to the Firestore emulator. I didn't check the others. But here's an example

connectAuthEmulator(auth, "http://127.0.0.1:9099");
connectFirestoreEmulator(db, "127.0.0.1", 8080);

The reason this is bad is because, apart from the fact that you have to use a different syntax for no reason and make it unintuitive, it's very easy to mess up and get non-helpful errors on the console. For example, if I try to connect to the Firestore emulator like this

connectFirestoreEmulator(db, "http://127.0.0.1", 8080);

I get the following error after a couple of seconds "Firestore (10.4.0): WebChannelConnection""RPC 'Write' stream 0x1d36fd2c transport errored:". It's not actually an error, but any Firestore operation won't work.

All I did was add the http:// like I do for the auth emulator, and it stopped working.

Please, normalize the method signature to connect to the emulator across all packages.

Steps and code to reproduce issue

Already explained.

Hi,

The Auth emulator is intentionally be made different than other Firebase's products since it wants to provide the ability to specify "http" or "https"

[marcusx2]

I see. So all the other emulators are implicitly "http" only?

Yes

Ok, thanks for the clarification. However, the part where I talk about the error generated should still be addressed I think. The error message is not obvious at all and it happens if you simply prepend "http" on the connectFirestoreEmulator.

Thank you for suggesting :) I will bring it as a feature request to the team.
