Issue
I am getting this error when I was trying to connect firebase with my React Native App.
Firebase Error: No Firebase App [DEFAULT] has been created - call Firebase App.initializeApp() (app/no-app)
I have added my code here-
import { initializeApp } from "firebase/app";
import { getAuth } from "firebase/auth";
import { getFirestore } from "firebase/firestore";
// Your web app's Firebase configuration
const RNfirebaseConfig = {
apiKey: "........",
authDomain: "note-app-rn.firebaseapp.com",
projectId: "note-app-rn",
storageBucket: "note-app-rn.appspot.com",
messagingSenderId: ".....",
appId: "......"
};
const app = initializeApp(RNfirebaseConfig);
export const auth = getAuth(app);
export const db = getFirestore(app);
Solution
try this,
import firebase from '@react-native-firebase/app';
import '@react-native-firebase/auth';
import '@react-native-firebase/firestore';
const RNfirebaseConfig = {
apiKey: "........",
authDomain: "note-app-rn.firebaseapp.com",
projectId: "note-app-rn",
storageBucket: "note-app-rn.appspot.com",
messagingSenderId: ".....",
appId: "......"
};
let app;
if (firebase.apps.length === 0) {
app = firebase.initializeApp(RNfirebaseConfig )
} else {
app = firebase.app()
}
const db = firebase.firestore();
const auth = firebase.auth();
