I installed firebase to my react app using npm install firebase command and initialized firebase like this
// Import the functions you need from the SDKs you need
import { initializeApp } from "firebase/app";
import { getAuth, GoogleAuthProvider } from "firebase/auth"
// TODO: Add SDKs for Firebase products that you want to use
// https://firebase.google.com/docs/web/setup#available-libraries
// Your web app's Firebase configuration
const firebaseConfig = {.........};
// Initialize Firebase
const app = initializeApp(firebaseConfig);
// export
export const auth = getAuth(app);
export const googleAuthProvider = new GoogleAuthProvider();
and i want to signInWithEmailLink method like this
import { signInWithEmailLink } from "firebase/auth";
const [email, setEmail] = useState("");
const [password, setPassword] = useState("");
useEffect(() => {
setEmail(window.localStorage.getItem('emailForRegistration'));
console.log(window.location.href);
console.log(window.localStorage.getItem("emailForRegistration"));
}, []);
const handleSubmit = async (e) => {
e.preventDefault();
try {
const result = await signInWithEmailLink(
email,
window.location.href
);
console.log("Result", result);
} catch (error) {
console.log(error);
}
};
and it give me this error
Don't use the useEffect() hook. Follow the instructions from the firebase docs here.

I set up my React project to use firebase auth using the modular v9 SDK like so. I now would like to create other hooks like useAnalytics, useFirestore, etc, that will allow me to access those utilities in components that need them. But if I use this same pattern for other firebase services, I will end up having to wrap my app with several contexts.
So instead of this auth provider component, I'm thinking of replacing it with a FirebaseProvider component that will wrap everything, but I am not sure if that is correct, or how I would integrate it with the existing auth code below.
import React, {useState, useContext, useEffect, createContext } from "react"
import {
getAuth,
signOut,
signInWithEmailAndPassword,
createUserWithEmailAndPassword,
} from "firebase/auth";
// I need to move this elsewhere like index.js
import { initializeApp } from "firebase/app";
firebase.initializeApp(<app config object>);
const auth = getAuth();
const authContext = createContext();
export const useAuth = () => {
return useContext()
}
// my App component is wrapped with this JSX element
export const ProvideAuth = ({children}) => {
const auth = useProvideAuth();
return <authContext.Provider value={auth}></authContext.Provider>
}
const useProvideAuth = () => {
const [user, setUser] = useState(null)
const signIn = (email, password) => {
signInWithEmailAndPassword(auth, email, password).then((res) => {
setUser(res.user)
})
}
const createUser = ...
const signOut = ...;
useEffect(() => {
const unsubscribe = onAuthStateChanged(auth, (user) => {
if (user) {
setUser(user);
} else {
setUser(false);
}
});
// remove listener on unmount
return () => unsubscribe();
}, []);
return {user, signIn, signOut, createUser};
}
I tried placing initializeApp in the index.js, but that code never seems to run and causes the authentication to fail.
I have created a Next.js application and am using Firebase authentication. I have used the useContext hook for managing user state across my application.
The code for the AuthContext is as follows:
auth.js
import { createContext, useState, useEffect, useContext } from "react";
import { getAuth, onIdTokenChanged } from "firebase/auth";
const AuthContext = createContext({});
export const AuthProvider = ({children}) => {
const auth = getAuth();
const [user, setUser] = useState(null);
useEffect(() => {
return(onIdTokenChanged(auth, (user) => {
if(user) {
setUser(user);
} else {
setUser(null);
}
}))
},[]);
return(<AuthContext.Provider value={{user}}>{children}</AuthContext.Provider>);
}
export const useAuth = () => useContext(AuthContext);
However, I'm getting the following error in the auth.js file:
I am not able to understand how to fix it.
Also, I want to know if using useContext() hook is better for route protection as opposed to storing user session cookies in the browser and verifying it from there.
Edit:
I have configured Firebase in firebaseConfig.js. The code for it is as follows:
firebaseConfig.js
import { initializeApp } from "firebase/app";
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,
};
// Initialize Firebase
export const app = initializeApp(firebaseConfig);
export const auth = getAuth(app);
I was just getting the same error, I managed to fix this by doing:
import { initializeApp } from 'firebase/app';
import { getAuth } from "firebase/auth";
import { getFirestore } from "firebase/firestore";
const firebaseConfig{
...
}
And adding these lines like that:
const app = initializeApp(firebaseConfig);
const auth = getAuth(app);
const db = getFirestore();
export { auth, db };
Initialize app like Marcos Oliveira said, with error handling:
try
{
const app = initializeApp(firebaseConfig);
const auth = getAuth(app);
} catch(error) {
console.log('Error:', error)
}
For anyone still dealing with this issue, my solution was to re-order my imports in the App.js.
For some reason, the components I imported needed to be in a specific order. Otherwise, the same error is thrown.
I did solve the problem by:
first I created a firebaseConfig.js file and put my configs and exported auth
import { initializeApp } from "firebase/app";
import { getAuth } from "firebase/auth";
const firebaseConfig = {
apiKey: "AIzaSyAzlY091r0Ihxxxxxx5F8",
authDomain: "mealxxxxxc.firebaseapp.com",
projectId: "mealxxxxxc",
storageBucket: "meaxxxxxpot.com",
messagingSenderId: "10xxxx00",
appId: "1:1092909165400:web:532xxxxx32d",
};
const app = initializeApp(firebaseConfig);
export const auth = getAuth(app);
then in authContext.js, I imported auth from firebaseConfig.js
import React, { useState, createContext } from "react";
import { signInWithEmailAndPassword } from "firebase/auth";
import { auth } from "../firebaseConfig";
export const AuthenticationContext = createContext();
export const AuthenticationContextProvider = ({ children }) => {
const [isLoading, setIsLoading] = useState(false);
const [error, setError] = useState(null);
const [user, setUser] = useState(null);
const onLogin = (email, password) => {
setIsLoading(true);
signInWithEmailAndPassword(auth, email, password)
.then((userData) => {
setUser(userData.user);
setIsLoading(false);
console.log("userData", userData.user);
})
.catch((er) => {
setIsLoading(false);
setError(er.toString());
console.log(er.message.toString());
});
};
So, for me, that error came about when I had all my firebase configurations on separate page/file (Firebase.js) including the following:
// Initialize Firebase
export const app = initializeApp(firebaseConfig);
export const db = getFirestore(app);
export const auth = getAuth(app);
export const storage = getStorage(app);
So, the initial setup for Firebase was okay.
However, I also had a separate page/file (App.js) where I called createUserWithEmailAndPassword(auth, email, password) as well as other built-in Firebase auth methods...
But, I forgot to import app from Firebase.js and that error popped up after I called createUserWithEmailAndPassword.
Once I did imported app, the error went away.
the problem is with the app object which is not getting initialized before the context provider render's
You should import the 'app' from firebaseConfig.js or whatever.js file your firebase configuration is in, into your Context file.
Note: make sure you are exporting the app from the configuration file
import { app } from 'location/to/firebaseConfig.js';
and in useEffect check for the 'app' if it exists then run the firebase-specific functions afterward and also add the 'app' to the dependency array.
useEffect(() => {
if (app) {
//enter firebase-specific code here
// for example:
onAuthStateChanged(auth, (user) => {
});
}
}, [app]);
you just need to export firebase conifgurations as app or any other type and re import it inside the page you are working on.
for me it was like this
`import { getAuth,signInWithEmailAndPassword } from "firebase/auth";
import { useState } from "react";
import { useNavigate } from "react-router-dom";
function SignInPage(){
const auth=getAuth();
const SignIn=()=>{
signInWithEmailAndPassword(auth,email,password)
.then((userCredentials)=>{
const user =userCredentials.user;
console.log(user);
alert("successfully loged a user")
})
.catch((error)=>{
const errorCode=error.code;
const errorMessage=error.message;
alert(errorCode,errorMessage);
});
}
const [email,setEmail]=useState("")
const [password,setPassword]=useState("")
return(
<div className="main">
<input type={"email"} placeholder="Email" onChange=
{(e)=>setEmail(e.target.value)}/>
<input type={"password"} placeholder="Password" onChange=
{(e)=>setPassword(e.target.value)}/>
<button onClick={()=>SignIn(email,password)}>Create Account</button>
</div>
)}
export default SignInPage;`
I'm trying to use firebase cloud functions in Next.js project, but there is some error I don't know how to fix.
firebase-config.js
const firebaseConfig = {
apiKey: '~~~',
authDomain: '~~',
projectId: '~~~',
storageBucket: '~~~',
messagingSenderId: '~~~~~',
appId: '~~~~~',
measurementId: '~~~~',
};
const app = initializeApp(firebaseConfig);
const db = getDatabase(app);
const auth = getAuth(app);
const functions = getFunctions(app);
let analytics = null;
if (app.name && typeof window !== 'undefined') {
analytics = getAnalytics(app);
}
export { db, auth, functions, analytics };
I deployed addMessage cloud function in my firebase and call this function inside /pages/friends page
import React, { useEffect, useState } from 'react'
import { doc, getDoc } from 'firebase/firestore';
import { auth, functions } from '../../firebase-config';
import { getAuth, onAuthStateChanged, signOut } from 'firebase/auth';
const addMessage = functions.httpsCallable('addMessage');
export default function FriendsPage() {
const [user, setUser] = useState(null);
const [friendsList, setFriendsList] = useState(null);
const currUser = auth.currentUser;
const _onAuthStateChanged = (handler) => {
if(!auth) return;
onAuthStateChanged(auth, (user) => { //TODO(aaron) : bug fix
if (user) {
const uid = user.uid;
console.log('AuthStateChanged', uid);
//user is signed in
handler(user);
} else {
// user is signed out
}
});
};
const addFriend = () => {
addMessage().then((res)=>{
console.log(res);
})
}
useEffect(()=>{
setFriendsList()
_onAuthStateChanged(setUser);
console.log(user);
}, []);
if(!user){
return(
<p>Loading...</p>
)
}
return (
<div>
<h3>{user.first}s friends List</h3>
<ul>
<li>h</li>
<li>h</li>
<li>h</li>
</ul>
<buton onClick={addFriend}>Call functions</buton>
</div>
)
}
But this error message pops up. I think it's probably a problem with when functions are loaded, how can I solve this?
Server Error
TypeError: _firebase_config__WEBPACK_IMPORTED_MODULE_2__.functions.httpsCallable is not a function
This error happened while generating the page. Any console logs will be displayed in the terminal window.

You're mixing up v8 and v9 syntax for callable functions. It seems that you're using v9 of the SDK in your app, not v8. When you import getFunctions, you don't get an object that has a method called httpsCallable. That's what the error message is trying to tell you. Instead, you need to import the function httpsCallable and pass it the function parameter as an argument. See the example in the documentation for v9.
import { getFunctions, httpsCallable } from "firebase/functions";
const functions = getFunctions();
const addMessage = httpsCallable(functions, 'addMessage');
I am new in vite. I am trying to initialize the firebase app. but I am getting errors like below
Firebase: No Firebase App '[DEFAULT]' has been created - call Firebase App.initializeApp()
I created a file name firebase.ts but i am not really sure where can i include this to initialize firebase globally.
<script setup lang="ts">
import { ref } from 'vue'
import { useRouter } from 'vue-router'
import { useHead } from '#vueuse/head'
import { isDark } from '/#src/state/darkModeState'
import useNotyf from '/#src/composable/useNotyf'
import sleep from '/#src/utils/sleep'
import { getAuth, signInWithEmailAndPassword } from '#firebase/auth'
const isLoading = ref(false)
const router = useRouter()
const notif = useNotyf()
const username = ref('')
const password = ref('')
const handleLogin = async () => {
if (!isLoading.value) {
isLoading.value = true
signInWithEmailAndPassword(getAuth(), username.value, password.value)
.then((user) => {
isLoading.value = false
router.push({ name: 'sidebar-dashboards-course' })
})
.catch((err) => {
isLoading.value = false
notif.error(
'There is no user record corresponding to this identifier. The user may be deleted'
)
})
}
}
Any solution appreciated!
In your firebase.ts, you are initializing Firebase using the compat version (that let's you use the name-spaced syntax even in V9) but you are trying to use the Modular version in your Vue components. Instead, try initializing Firebase using modular SDK as well. So the firebase.ts should look like:
import { initializeApp } from "firebase/app";
import { getAuth } from "firebase/auth";
import { getFirestore } from "firebase/firestore";
import { getStorage } from "firebase/storage";
const firebaseConfig = {...};
const app = initializeApp(firebaseConfig);
const auth = getAuth(app);
const db = getFirestore(app);
const storage = getStorage(app);
export { auth, db, storage };
Then try importing these instances in your components instead of using get[Service]() functions again.
import { auth } from "../path/to/firebase.ts" // update the path as per your dir structure
// usage: instead of getAuth() here
await signInWithEmailAndPassword(auth, username.value, password.value)
i'm in the middle to learn Auth with Firebase using NextJS, tryin to understand using multiple source (article / youtube) but i'm stuck with this error
ReferenceError: Cannot access 'auth' before initialization
Honestly i'm still tryin to find the source but still stuck
Here's my firebase.js
import { firebase, initializeApp } from "firebase/app";
import { getAnalytics } from "firebase/analytics";
const firebaseConfig = {
apiKey: process.env.APIKEY,
authDomain: process.env.AUTH,
projectId: process.env.PID,
storageBucket: process.env.BUCKET,
messagingSenderId: process.env.MSID,
appId: process.env.AID,
measurementId: process.env.MID,
};
const app = !firebase.apps.length
? initializeApp(firebaseConfig)
: firebase.app();
const analytics = getAnalytics(app);
const auth = app.auth();
const db = app.firestore();
const googleProvider = new firebase.auth.GoogleAuthProvider();
export {
auth,
db,
signInWithGoogle,
...
};
and this is my login.js page
import React, { useEffect, useState } from "react";
import {
auth,
signInWithEmailAndPassword,
signInWithGoogle,
} from "../../firebase/index";
import Link from "next/link";
import { useAuthState } from "react-firebase-hooks/auth";
function Login() {
const [email, setEmail] = useState("");
const [password, setPassword] = useState("");
const [user, loading, error] = useAuthState(auth);
useEffect(() => {
if (loading) {
// maybe trigger a loading screen
return;
}
if (user) {
alert("GET USER");
console.log(user);
}
}, [user, loading]);
return (
...
I'm using
"firebase": "^9.6.1",
"firebase-admin": "^10.0.1",
am i doing something wrong? or am i missing something? please help:(
You must import getAuth() from Firebase Auth SDK and then initialize it as shown below:
import { initializeApp } from "firebase/app";
import { getAuth } from "firebase/auth";
import { getFirestore } from "firebase/firestore";
import { getAnalytics } from "firebase/analytics";
const firebaseConfig = {...};
const app = initializeApp(firebaseConfig)
const analytics = getAnalytics(app);
const auth = getAuth(app);
const db = getFirestore(app);
export {
auth,
db,
};
You don't need to check if Firebase has already been initialized when using Modular SDK.
First of all, you are using the legacy version of firebase I recommend you to use newer versions (9.9.2 atm).
About your problem ; it seems like you need to call getAuth() or initializeAuth() functions before try to get instance of auth.
