Error: Firebase encountered an issue as there is an existing Firebase App named '[DEFAULT]' with conflicting options or configuration details (app/duplicate-app)

https://i.sstatic.net/jdc0C.png

This is the complete code I have written:

import { initializeApp } from "firebase/app";
import { getAuth } from "firebase/auth";

const firebaseConfig = {
  apiKey: "APIKEY",
  authDomain: "AUTHDOMAIN",
  projectId: "PROJID",
  storageBucket: "BUCKET",
  messagingSenderId: "SOMEID",
  appId: "APPID",
  measurementId: "IDDDDD"
};

const app = initializeApp(firebaseConfig);
export const auth = getAuth(app);

I'm facing some issues with my code and struggling to identify the problem. Despite checking for errors, everything seems correct. Can someone please guide me on how to resolve this? D:

Answer №1

There are occasions where importing the firebase.js file into multiple other files can result in two instances of the app being created. To avoid this issue, you can utilize the following code snippet:

const app = !getApps().length ? initializeApp(firebaseConfig) : getApp();

Remember to include imports for getApps() and getApp() in your code.
