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'm building a project in React where it has authentication so I'm using firebase
I have encountered this error
Firebase: Need to provide options, when not being deployed to hosting via source. (app/no-options)
here is my config-firebase file:
import { initializeApp } from "firebase/app";
import { getAuth } from "firebase/auth";
// For Firebase JS SDK v7.20.0 and later, measurementId is optional
const firebaseConfig = {
apiKey: "AIzaSyBoKEW_g0gOwNKkHGMAyhXxC0ESfdsVhKI",
authDomain: "kargoevi-auth.firebaseapp.com",
projectId: "kargoevi-auth",
storageBucket: "kargoevi-auth.appspot.com",
messagingSenderId: "726037811463",
appId: "1:726037811463:web:42d75c7f5c1d1b5b9bf5a2",
measurementId: "G-PJXGLVZ6GQ",
};
export const auth = getAuth(app);
const app = initializeApp(firebaseConfig);
export default app;
here is my Auth file:
import React, { useState, useEffect } from "react";
import { onAuthStateChanged } from "firebase/auth";
import { auth } from "./base";
export const AuthContext = React.createContext();
export const AuthProvider = ({ children }) => {
const [currentUser, setCurrentUser] = useState(null);
const [pending, setPending] = useState(true);
useEffect(() => {
onAuthStateChanged(auth, (user) => {
setCurrentUser(user);
setPending(false);
});
}, []);
if (pending) {
return <>Loading...</>;
}
return (
<AuthContext.Provider
value={{
currentUser,
}}
>
{children}
</AuthContext.Provider>
);
};
note: I'm not trying to deploy it yet
any ideas on how can I fix this error?
Firebase app must be initialized before you use any other Firebase services so make sure the initializeApp() function is called first.
// correct order
const app = initializeApp(firebaseConfig);
export const auth = getAuth(app);
It's best to use the exported auth instance in other files. If you use getAuth() in other files as well, there's a chance initializeApp() has not been called yet leading to same error.
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 building a blog app using Firebase version: 9, VueJs version: 3 and VueX.
All the functionalities like registering the user and authentication works, And when it comes to set a user as an Admin using firebase functions I got the error which I don't understand why it is happening.
The error I'm getting is the following:
When I remove error catch I got this one
Can you help me!
By following the docs at https://firebase.google.com/docs/functions/callable it say that we have to initialize the functions like below:
here it's in firebaseInit.js file
// Import the functions you need from the SDKs you need
import { initializeApp } from "firebase/app";
import {
getFirestore,
} from "firebase/firestore"
import { getFunctions } from 'firebase/functions';
// Your web app's Firebase configuration
const firebaseConfig = {
apiKey: "###",
authDomain: "###",
projectId: "###",
storageBucket: "###",
messagingSenderId: "###",
appId: "###"
};
// Initialize Firebase and Functions
const app = initializeApp(firebaseConfig);
const functions = getFunctions(app);
// Init services
const db = getFirestore(app);
export { functions }
export default db;
and in Admin view where I use to set the Admin role I have called the functions like below:
here it's in Admin.vue file
<template>
<div class="admin">
<div class="container">
<h2>Administration</h2>
<div class="admin-info">
<h2>Add Admin</h2>
<div class="input">
<input placeholder="Enter user email to make them an admin" type="text" id="addAdmins" v-model="adminEmail" />
</div>
<span>{{ this.functionMsg }}</span>
<button #click="addAdmin" class="button">Submit</button>
</div>
</div>
</div>
</template>
<script>
import { functions } from "../firebase/firebaseInit"
import { getFunctions, httpsCallable } from "firebase/functions"
export default {
name: "Admin",
data() {
return {
adminEmail: "",
functionMsg: null
}
},
methods: {
async addAdmin() {
const functions = getFunctions();
const setAdminRole = await httpsCallable(functions, "addAdminRole");
setAdminRole({ email: this.adminEmail })
.then((result) => {
const data = result.data;
this.functionMsg = data.message;
})
.catch((error) => {
// Getting the Error details.
const code = error.code;
const message = error.message;
const details = error.details;
console.log(code);
console.log(message);
console.log(details);
});
}
}
}
</script>
Here is the Callable Cloud Function deployed to Firebase functions services in index.js
:
const functions = require("firebase-functions");
// The Firebase Admin SDK to access Firestore.
const admin = require("firebase-admin");
admin.initializeApp();
exports.addAdminRole = functions.https.onCall((data, context) => {
return admin.auth.getUserByEmail(data.email)
.then((user) => {
return admin.auth().setCustomUserClaims(user.uid, {
admin: true
});
}).then(() => {
return {
message: `Success! ${ data.email } has been made an admin!!`
}
})
.catch((err) => {
console.log(err.message);
});
});
In your component you should not do:
import { functions } from "../firebase/firebaseInit"
import { getFunctions, httpsCallable } from "firebase/functions"
// ...
async addAdmin() {
const functions = getFunctions();
const setAdminRole = await httpsCallable(functions, "addAdminRole");
setAdminRole({ email: this.adminEmail })
....
but just
import { functions } from "../firebase/firebaseInit"
import { httpsCallable } from "firebase/functions"
// ...
async addAdmin() {
const setAdminRole = await httpsCallable(functions, "addAdminRole");
setAdminRole({ email: this.adminEmail })
....
since you export functions in your firebaseInit.js file.
ok so ive been building a discord clone with react redux, right now im stuck on the sign in page. it keeps giving me this error "Uncaught TypeError: firebase__WEBPACK_IMPORTED_MODULE_0_.app.auth is not a function" heres my code in firebase.js

console.log(err)
})
}
return (
<div className='login'>
<h2> I am the login page</h2>
<Button onClick={signIn}>Sign In</Button>
</div>
);
}
export default Login
I have no idea whats going on, ive read some other posts and people are saying to install older versions of firebase, I tried to do that and it still didnt work. Ive been stumped on this for nearly 2 days now
I assume you are using firebase 9. there you have to use js modules.
https://firebase.google.com/docs/web/modular-upgrade
import { getAuth, signInWithPopup, GoogleAuthProvider } from "firebase/auth";
const auth = getAuth();
signInWithPopup(auth, provider)
.then((result) => {
// This gives you a Google Access Token. You can use it to access the Google API.
const credential = GoogleAuthProvider.credentialFromResult(result);
const token = credential.accessToken;
// The signed-in user info.
const user = result.user;
// ...
}).catch((error) => {
// Handle Errors here.
const errorCode = error.code;
const errorMessage = error.message;
// The email of the user's account used.
const email = error.email;
// The AuthCredential type that was used.
const credential = GoogleAuthProvider.credentialFromError(error);
// ...
});
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

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.
