React Native Firebase Emulator on LAN environment

[ithustle]

Hi there,

Is it possible run react-native-firebase emulator with a local network server IP?
Using auth().useEmulator(http://${SERVER_IP}:9099) the Auth instance doesn't communicate with Firebase Auth Emulator and using firestore().useEmulator(SERVER_IP, 8080) it return the following message:

Error: firebase.firestore().useEmulator() takes a non-empty host and port

Unfortunately the emulator config is a little disjoint - auth takes a slightly different format than the others, but you may see how we configure them here, I believe you can replace "localhost" with a server IP in any of those and it should work?

react-native-firebase/tests/app.js

Lines 49 to 53 in 4c7840a

	firebase.database().useEmulator('localhost', 9000);
	}
	firebase.auth().useEmulator('http://localhost:9099');
	firebase.firestore().useEmulator('localhost', 8080);
	firebase.storage().useEmulator('localhost', 9199);

Hi @mikehardy.
Thanks for reply.

I did exactly the same:

const SERVER_IP = 'server_ip_on_my_lan';
...
if (__DEV__) {
        firestore().settings({ ssl: false, cacheSizeBytes: firestore.CACHE_SIZE_UNLIMITED });
        functions().useFunctionsEmulator(`http://${SERVER_IP}:5001`);
        firestore().useEmulator(SERVER_IP, 8080);
        auth().useEmulator(`http://${SERVER_IP}:9099`);
        storage().useEmulator(SERVER_IP, 9199);
    } else {
        firestore().settings({ cacheSizeBytes: firestore.CACHE_SIZE_UNLIMITED });
    }

...and still throw this message: Error: firebase.firestore().useEmulator() takes a non-empty host and port, js engine: hermes.

Any tips?

Replacing the variable SERVER_IP to IP works. :/
