I am having issues implementing firebase authentication with Google Provider in NextJS. I set up the environment variables and am successfully connecting to firebase. I am receiving the following error and cant seem to figure out a solution, TypeError: Cannot read properties of undefined (reading 'GoogleAuthProvider'). Below is my code.
//firebaseApp.js
import { initializeApp, getApps } from "firebase/app"
import { getFirestore } from "firebase/firestore"
import { getAuth } from "firebase/auth"
const firebaseConfig = {
apiKey: process.env.NEXT_PUBLIC_FIREBASE_API_KEY,
authDomain: process.env.NEXT_PUBLIC_FIREBASE_AUTH_DOMAIN,
projectId: process.env.NEXT_PUBLIC_FIREBASE_PROJECT_ID,
storageBucket: process.env.NEXT_PUBLIC_FIREBASE_STORAGE_BUCKET,
messagingSenderId: process.env.NEXT_PUBLIC_FIREBASE_MESSAGING_SENDER_ID,
appId: process.env.NEXT_PUBLIC_FIREBASE_APP_ID,
measurementId: process.env.NEXT_PUBLIC_FIREBASE_MEASUREMENT_ID,
};
if (getApps().length === 0) {
console.log('Error Connecting to Firebase')
}
const app = initializeApp(firebaseConfig)
const db = getFirestore(app)
const auth = getAuth(app)
export { db, auth }
//firebaseAuthUI.config.js
export const uiConfig = (firebase) => {
return {
signInFlow: "popup",
signInSuccessUrl: "/",
signInOptions: [firebase.auth.GoogleAuthProvider.PROVIDER_ID],
};
};
//login.js
import Head from 'next/head';
import { useRouter } from 'next/router';
import { useAuthState } from 'react-firebase-hooks/auth';
import StyledFirebaseAuth from 'react-firebaseui/StyledFirebaseAuth';
import { auth, firebase } from '../app/firebaseApp';
import { uiConfig } from '../config/firebaseAuthUI.config';
export default function Login() {
const [user, loading, error] = useAuthState(auth);
const router = useRouter();
if (loading) return 'loading'
else if (error) return error
else if (user) {
router.push('/');
}
const authConfig = uiConfig(auth);
return (
<>
<Head>
<title>Login</title>
</Head>
<StyledFirebaseAuth uiConfig={authConfig} firebaseAuth={auth} />
</>
)
}I think the example code you copy from uses module 8
try to import GoogleAuthProvider like this, check firebase ref
import { GoogleAuthProvider} from "firebase/auth"
...
...
export const uiConfig = (firebase) => {
return {
signInFlow: "popup",
signInSuccessUrl: "/",
signInOptions: [GoogleAuthProvider.PROVIDER_ID],
};
};
