Redirecting to home page - javascript

I have the next following problem in my vue registration. When I click register it redirects me to the home page. Maybe using some conditions could solve this problem. How can I prevent this from happening? Any ideas?
My Javascript:
register() {
firebase
.auth()
.createUserWithEmailAndPassword(this.email, this.lozinka)
.then(
function() {
console.log('Success');
let id = this.email
db.collection("user")
.doc(id)
.set({
korisnicko_ime: this.korisnicko_ime,
email: this.email,
lokacija: this.lokacija,
ime_objekta: this.ime_objekta,
kontakt: this.kontakt,
})
.then((doc) => {
console.log("Saved", doc)
})
})
.catch(function(error) {
console.error("Error...", error);
if ( store.currentUser=null ) {
this.$router.replace({ name: 'Register'});
}
});
console.log('Continue');
this.$router.replace({ name: 'Home'});
},

I do not know what you are actually trying to achieve but what you are doing is fireing a request, register your callbacks on the request's promise and immediately replace your current route.
register() {
firebase
.auth()
.createUserWithEmailAndPassword(this.email, this.lozinka)
.then(successCallback)
.catch(errorCallback);
this.$router.replace({ name: 'Home'});
}
I guess you probably want to wait for the response of your register request and redirect your user based on whether the promise resolved successfully or with an error?
At first you probably should have a deeper look at
Promises with its async/await syntax
Using const over let/var
async register() {
try {
const registerResponse = await firebase
.auth()
.createUserWithEmailAndPassword(this.email, this.lozinka);
console.log("Success");
const id = this.email;
const collectionResponse = await db
.collection("user")
.doc(id)
.set({
korisnicko_ime: this.korisnicko_ime,
email: this.email,
lokacija: this.lokacija,
ime_objekta: this.ime_objekta,
kontakt: this.kontakt,
});
console.log("Saved", doc);
// After everything was successfull, redirect to home
this.$router.replace({ name: 'Home'});
} catch(error) {
console.error("Error...", error);
if ((store.currentUser = null)) this.$router.replace({ name: "Register" });
}
}

How to make a post request by SERVER not by user

Node.js CODE
exports.user = async (req, res) => {
try {
const { wallet } = req.body;
if (!wallet) {
res.status(400).json({ error: "Not logged in" });
return;
} else {
user = User.findone(wallet);
// if user is not found then create a new user and mark as loggged In
if (!user) {
User.create({
user: wallet,
});
}
// if user found then create a session token and mark as logged
in
res.send({
user: wallet,
});
}
} catch (error) {
console.log(`ERROR::`, error);
}
};
REACTJs CODE
// post call/update
const axiosCall = async () => {
// core login will give a unique username by fulling a transcation
// core.login i dont have any control
const userAccount = await core.login();
try {
const res = await Axios.post(`${API}/user`, userAccount, dataToken);
setData({
...data,
error: "",
success: res.data.message,
});
} catch (error) {
setData({
...data,
error: error.response.data.error,
});
}
};
Now here the problem occurs when some one could modify userAccount in the front-end or someone could send a body with wallet: anything to my route localhost:3000/api/user
There is no option for me to check if some actually used core.login(); to get the wallet address.
So is there any solution?
I was thinking to allow only my server IP or localhost to hit the route localhost:3000/api/user and is that even possible?
Also there is another issue anyone could modify userAccount in front-end.

How do I set specific roles to redirect from specific routes with Custom Claims?

I am using NodeJS, Express and plain vanilla javascript/html. Not React or anything else.
With firebase I made it to when the user registers, they will automatically be called a customer (on the server-side). As shown:
server.js
app.post('/register', (req,res) => {
let {first_name, last_name, email, uid} = req.body;
db.collection('users').doc(uid).set(req.body)
.then(data => {
res.json({
uid: req.body.uid,
first_name: req.body.first_name,
last_name: req.body.last_name,
email: req.body.email,
seller: req.body.seller
})
})
admin.auth()
.setCustomUserClaims(uid, {
type: "customer",
})
.then(() => console.log('done'))
})
But now, I would like to make this route to where it will redirect if the type is a customer.
if(idToken.claim.type === 'customer') {redirect('/') }
app.get('/seller', (req,res) => {
res.sendFile(path.join(staticPath, "seller.html"));
})
So I thought, what if I were to get the Token from the user and the type as soon as they log in, and send it back to the client. This will work.
login.js
firebase.auth().currentUser.getIdTokenResult()
.then((idTokenResult) => {
fetch('/getMyClaims', {
method: 'post',
headers: {'Content-Type':'application/json'},
body: JSON.stringify({uid: user.uid,
idToken: idTokenResult.claims.type}),
})
.then(() => res.json)
.catch(err => console.log(err));
});
and now my server.js now includes:
app.post('/getMyClaims', async(req,res) => {
let {uid,idToken} = req.body;
admin.auth()
.getUser(uid)
.then((userRecord) => console.log(userRecord))
})
and this is where I get stuck, because I am trying to find out how can I call the results of '/getMyClaims' to redirect a user, if they are a customer and are trying to access the '/seller' URL.
I did read the documents as given https://firebase.google.com/docs/auth/admin/custom-claims, but it does not really show how to re-route if claim has a specific type in the backend.
I've figured things out after hours of this!
server.js
var block;
var blockware = (req,res,next) => {
if(block == true || block == undefined){
console.log("deny access", block);
return res.sendStatus(401);
}
console.log("allow",block);
next();
}
app.post('/getMyClaims', async(req,res) => {
let {uid,idToken} = req.body;
if(idToken === 'customer'){
block = true;
} else if(idToken === 'admin'){
block = false;
} else {
block = true;
}
admin.auth()
.getUser(uid)
.then((userRecord) => console.log(userRecord))
})
app.get(['/seller', '/products', '/'], blockware, (req,res) => {
res.sendFile(path.join(staticPath, ""));
})
So now if user has a customer type claim then they are blocked from accessing seller. Otherwise, admin can access seller.
Even when user is logged out since it is automatically set to true, everyone will be blocked from it.

Next-Auth signIn with Credentials is not working in NextJS

I'm integrating next-auth package to my fresh Next.js project. I have followed all of the Next.js and next-auth documentations but not able to find a solution.
The issue I'm facing goes like this:
I want to Login to my Next.js app using Email & Password submitted to my API Server running on Laravel.
When submitting the login form I'm executing the below function.
import { signIn } from "next-auth/client";
const loginHandler = async (event) => {
event.preventDefault();
const enteredEmail = emailInputRef.current.value;
const enteredPassword = passwordInputRef.current.value;
const result = await signIn("credentials", {
redirect: false,
email: enteredEmail,
password: enteredPassword,
});
console.log("finished signIn call");
console.log(result);
};
And code shown below is in my pages/api/auth/[...nextauth].js
import axios from "axios";
import NextAuth from "next-auth";
import Providers from "next-auth/providers";
export default NextAuth({
session: {
jwt: true,
},
providers: [
Providers.Credentials({
async authorize(credentials) {
axios
.post("MY_LOGIN_API", {
email: credentials.email,
password: credentials.password,
})
.then(function (response) {
console.log(response);
return true;
})
.catch(function (error) {
console.log(error);
throw new Error('I will handle this later!');
});
},
}),
],
});
But when try to login with correct/incorrect credentials, I get the below error in Google Chrome console log.
POST http://localhost:3000/api/auth/callback/credentials? 401 (Unauthorized)
{error: "CredentialsSignin", status: 401, ok: false, url: null}
Am I missing something here?
From the documentation (https://next-auth.js.org/providers/credentials#example)
async authorize(credentials, req) {
// Add logic here to look up the user from the credentials supplied
const user = { id: 1, name: 'J Smith', email: 'jsmith#example.com' }
if (user) {
// Any object returned will be saved in `user` property of the JWT
return user
} else {
// If you return null or false then the credentials will be rejected
return null
// You can also Reject this callback with an Error or with a URL:
// throw new Error('error message') // Redirect to error page
// throw '/path/to/redirect' // Redirect to a URL
}
}
You are not currently returning a user or null from the authorize callback.
Answer posted by shanewwarren is correct, but here is more elaborated answer,
Using axios to solve this
async authorize(credentials, req) {
return axios
.post(`${process.env.NEXT_PUBLIC_STRAPI_API}/auth/login`, {
identifier: credentials.identifier,
password: credentials.password,
})
.then((response) => {
return response.data;
})
.catch((error) => {
console.log(error.response);
throw new Error(error.response.data.message);
}) || null;
},

How to make sure all data is written into Firestore in a sequential order?

I'm trying to create a user profile that states that that profile is from one of the business owners in my app. It is supposed to create the profile and then merge info such as the 'roles' array with 'businessOwner' in it and also add the 'businessId'.
Sometimes, the code will work seamlessly. At other times, only the roles and the businessId will be passed to the created user (and all of the other information won't!).
async function writeToFirebase(values) {
authService.createUserWithEmailAndPassword(values.user.email, values.user.senha).then(
async function (user) {
userService.createUserProfileDocument(values.user)
const uid = user.user.uid
const userRef = await userService.doc(uid)
console.log('userRef', userRef)
try {
values.user.uid = uid
const { id } = await businessPendingApprovalService.collection().add(values)
await userRef.set({ roles: ['businessOwner'], businessId: id }, { merge: true })
} catch (error) {
console.error('error merging info')
}
},
function (error) {
var errorCode = error.code
var errorMessage = error.message
console.log(errorCode, errorMessage)
},
)
}
This is createUserWithEmailAndPassword:
async createUserProfileDocument(user, additionalData) {
if (!user) return
const userRef = this.firestore.doc(`users/${user.uid}`)
const snapshot = await userRef.get()
if (!snapshot.exists) {
const { displayName, email, photoURL, providerData } = user
try {
await userRef.set({
displayName,
email,
photoURL,
...additionalData,
providerData: providerData[0].providerId,
})
} catch (error) {
console.error('error creating user: ', error)
}
}
return this.getUserDocument(user.uid)
}
I think that the issue is on this line const snapshot = await userRef.get().
As stated in documentation you should fetch the snapshot using then() function in order to return the promise first.
I think you need to await on the below as well:-
await userService.createUserProfileDocument(values.user)
Since you are setting the user info here(await userRef.set), if you will not wait for the promise, then sometimes, your next block of code(await userRef.set({ roles: ['businessOwner'],) executes and after then your promise might get resolved. Because of this, you might not get the other information sometimes.
You also need to handle the error case of createUserProfileDocument.

Firebase Function/ Express: Can't set headers after they are sent

I've mostly utilised the Hapi framework to build RESTful APIs. For this project I'm using Express and I'm a bit lost as to why this is happening.
When I test the POST endpoint using Postman, the first request is fine, but I would get an error when I make the second request.
Error: Can't set headers after they are sent.
The code for the route handler is below:
const login = (req, res) => {
const validation = authScema.loginPayload.validate(req.body)
if (validation.error) {
return res.status(400).send(validation.error.details[0].message)
}
const { email, password } = req.body
firebase
.auth()
.signInWithEmailAndPassword(email, password)
.catch(error => {
// Handle Errors here.
if (error) {
return res.status(400).send('Invalid login details.')
}
})
firebase.auth().onAuthStateChanged(user => {
if (user) {
const userObject = {
email: user.email,
uid: user.uid
}
const token = jwt.sign(userObject, secret)
return res.status(200).send(token)
}
})
}
I don't understand why headers are resent since in every branch, I return. It should have exited the function, right?
Turns out, signInWithEmailAndPassword
is a promise that returns the user in the happy path
So, the following is the final code:
firebase
.auth()
.signInWithEmailAndPassword(email, password)
.then(user => {
const userObject = {
email: user.email,
uid: user.uid
}
const token = jwt.sign(userObject, secret)
res.status(200).json({ token })
})
.catch(error => {
if (error) {
res.status(400).json({ message: 'Invalid login details.' })
}
})
The onOnAuthStateChanged is not necessary in this case.
