Google Firebase Authentication with Expo not returning anything

I am Creating an expo app in which a user can login using Gmail.
I followed this firebase documentation to implement that functionality but whenever I click on login, it doesn't neither save the data in the database nor return any error.
This is my firebase function:
isUserEqual = (googleUser, firebaseUser)=> {
if (firebaseUser) {
var providerData = firebaseUser.providerData;
for (var i = 0; i < providerData.length; i++) {
if (providerData[i].providerId === firebase.auth.GoogleAuthProvider.PROVIDER_ID &&
providerData[i].uid === googleUser.getBasicProfile().getId()) {
// We don't need to reauth the Firebase connection.
return true;
}
}
}
return false;
}
onSignIn = (googleUser)=> {
console.log('Google Auth Response', googleUser);
// We need to register an Observer on Firebase Auth to make sure auth is initialized.
var unsubscribe = firebase
.auth()
.onAuthStateChanged(function(firebaseUser) {
unsubscribe();
// Check if we are already signed-in Firebase with the correct user.
if (!this.isUserEqual(googleUser, firebaseUser)) {
// Build Firebase credential with the Google ID token.
var credential = firebase.auth.GoogleAuthProvider.credential(
googleUser.idToken,
googleUser.accessToken
);
// Sign in with credential from the Google user.
firebase.auth()
.signInAndRetrieveDataWithCredential(credential)
.then(function(result) {
console.log('User signed in');
})
.catch(function(error) {
// Handle Errors here.
var errorCode = error.code;
var errorMessage = error.message;
// The email of the user's account used.
var email = error.email;
// The firebase.auth.AuthCredential type that was used.
var credential = error.credential;
// ...
});
} else {
console.log('User already signed-in Firebase.');
}
}.bind(this)
);
};
signInWithGoogleAsync = async() => {
try {
const result = await Expo.Google.logInAsync({
behavior: 'web',
androidClientId: '929952027781-5ao9pp7n5n0sj2n70i5tp7klfro88bgp.apps.googleusercontent.com',
iosClientId: '929952027781-7obs66o3kr59kdhp6ll0c9598ue3u8aa.apps.googleusercontent.com',
scopes: ['profile', 'email'],
});
if (result.type === 'success') {
this.onSignIn(result);
return result.accessToken;
} else {
return {cancelled: true};
}
} catch(e) {
return {error: true};
}
}
And this is my login button:
<TouchableOpacity style={styles.AuthOptionGmail} onPress={() => signInWithGoogleAsync()}>
<Ionicons color='#ffffff' style = {styles.BtnIcon} name="logo-google" size={25}/>
<Text style={{fontSize:16,color:'#ffffff', textAlign:'center'}}>Login with Gmail</Text>
</TouchableOpacity>
Can anyone tell me where I messed up please????

with Expo sdk 32 and above following worked for me , just install "expo-google-app-auth"
import * as Google from "expo-google-app-auth";
signInWithGoogleAsync = async () => {
console.log("signInWithGoogleAsync");
try {
//clientId
const { type, accessToken, user, idToken } = await Google.logInAsync({
behavior: "web",
androidClientId:
"your id",
iosClientId:
"your id",
scopes: ["profile", "email"]
});
if (type === "success") {
console.log("accessToken" + accessToken);
console.log("idToken" + idToken);
console.log(user);
return accessToken;
} else {
return { cancelled: true };
}
} catch (e) {
console.log(e);
return { error: true };
}
};

Check that email exists with Node within API

Introduction
Ok, I have Three functions. the first two generate data for the third.
Gets post data (email)
Gets API key
Uses API key, User_key and email and post them to the API
What I need
I need the third to print the following to my console providing the email is present.
else {
console.log("Login successful !");
console.log("API Key", api);
console.log("userKey", userkey);
console.log("useremail", login_email);
console.error("Third You have logged in !");
}
What I am getting
error null
I am getting this even though I post a email that exist. Dose anyone see where I am going wrong in my code ?

firebase invalid email authentication error

When I login to my firebase v 2.4.1 app using email / password auth with an invalid email. Firebase throws an error internally and I can't seem to find a way to catch it.
The examples here work, but they are using v.1.1.1 and when I swap the libraries in my app to 1.1.1 it seems to work also
Am I missing something or is this a known issue?

I removed the 1.1.1 reference from your jsFiddle and added the 2.4.1 one (https://cdn.firebase.com/js/client/2.4.1/firebase.js) and then tried it with a random email and it reacted exactly the same as with the previous version. Can you give me more details on how to reproduce it? I was using Chrome.

Javascript promise chaining

I'm having quite a hard time understanding how to chain promises. I'm writing login function for my app, leverating Loopback's Angular SDK. The objective, upon validating a user's credentials, is to confirm that the user's account is active, then fetch some additional properties including the user's role and set a flag to true if the user has admin privileges.
Here's my code...
$scope.login = function (user) {
User.login(user).$promise.then(
function (data) {
$rootScope.activeUser = data;
$rootScope.user_id = $rootScope.activeUser.user.username;
console.log('Active User: ', $rootScope.activeUser.user.email);
console.log('Status: ', $rootScope.activeUser.user.status);
if ($rootScope.activeUser.user.status === 'Y') {
$scope.loginError = false;
function checkAdmin(eid) {
Se_user.findById({
id: eid
}).$promise.then(
function (data1) {
var user_properties = data1;
if (user_properties.role === 'Admin') {
$rootScope.isAdmin = true;
console.log('isAdminInside: ', $rootScope.isAdmin);
return true;
} else {
//$rootScope.isAdmin = false;
return false;
}
});
};
var isAdmin = checkAdmin($rootScope.user_id);
console.log('isAdminOutside: ', $rootScope.isAdmin);
$state.go('home');
} else {
$scope.loginError = true;
$scope.loginErrorMessage = "Your account has been disabled. Please contact BMT Support for assistance";
}
},
function (err) {
console.log('Error: ', err)
$scope.loginError = true;
$scope.loginErrorMessage = "You've entered an invalid User ID or Password. Please try again.";
});
};
I've been troubleshooting by writing to the console, here's a sample of the output...
Active User: user#email.com
Status: Y
isAdminOutside: undefined
isAdminInside: true
How should I restructure so that the result of checkAdmin is properly returned after a successful login of an active user?

Try changing this part of code :
function checkAdmin(eid) {
return Se_user.findById({
id: eid
}).$promise.then(
function(data1) {
var user_properties = data1;
if (user_properties.role === 'Admin') {
$rootScope.isAdmin = true;
console.log('isAdminInside: ', $rootScope.isAdmin);
return true;
} else {
//$rootScope.isAdmin = false;
return false;
}
});
};
var isAdmin = checkAdmin($rootScope.user_id)
.then(function(val) {
console.log('isAdminOutside: ', val);
$state.go('home');
});

Check if User has Role - Parse Cloud Code

Writing a Parse Cloud Function (which uses Parse Javascript SDK) and I am having trouble checking to see if the current user has role "Admin". I'm looking at the web view of the Role class and a role with the name "Admin" exists, if I click "View Relations" for users, it shows the current user. I doubt it should matter, but "Admin" is the only role and the current user is the only user with a role. Lastly, the "Admin" role has an ACL of Public Read, so that shouldn't be causing any issues either.
Code is as follows:
...
var queryRole = new Parse.Query(Parse.Role);
queryRole.equalTo('name', 'Admin');
queryRole.equalTo("users", Parse.User.current());
queryRole.first({
success: function(result) { // Role Object
var role = result;
role ? authorized = true : console.log('Shiet, user not Admin');
},
error: function(error) {
console.log("Bruh, queryRole error");
}
})
console.log('After test: Auth = ' + authorized);
if (!authorized) {
response.error("You ain't no admin, measly user");
return;
}
...
This results in the following in the log:
Before test: Auth = false
After test: Auth = false

Give this a shot:
var authorized = false;
console.log('Before test: Auth = ' + authorized);
var queryRole = new Parse.Query(Parse.Role);
queryRole.equalTo('name', 'Admin');
queryRole.first({
success: function(result) { // Role Object
console.log("Okay, that's a start... in success 1 with results: " + result);
var role = result;
var adminRelation = new Parse.Relation(role, 'users');
var queryAdmins = adminRelation.query();
queryAdmins.equalTo('objectId', Parse.User.current().id);
queryAdmins.first({
success: function(result) { // User Object
var user = result;
user ? authorized = true : console.log('Shiet, user not Admin');
}
});
},
error: function(error) {
console.log("Bruh, can't find the Admin role");
}
}).then(function() {
console.log('After test: Auth = ' + authorized);
});

I got a simpler solution, give this a try:
var adminRoleQuery = new Parse.Query(Parse.Role);
adminRoleQuery.equalTo('name', 'admin');
adminRoleQuery.equalTo('users', req.user);
return adminRoleQuery.first().then(function(adminRole) {
if (!adminRole) {
throw new Error('Not an admin');
}
});

For those of you looking for a Parse Server (2018) answer, see below:
Parse.Cloud.define('authorizedUserTest', function(request, response) {
if(!request.params.username){
//response.error('no username');
response.error(request.params);
}
var queryRole = new Parse.Query(Parse.Role);
queryRole.equalTo('name','Admin');
queryRole.first({ useMasterKey: true }).then(function(promise){
var role = promise;
var relation = new Parse.Relation(role, 'users');
var admins = relation.query();
admins.equalTo('username', request.user.get('username'));
admins.first({ useMasterKey: true }).then(function(user){
if(user){
response.success(true)
}
else {
response.success(false)
}
}, function(err){
response.error('User is not an admin')
})
}, function(err){
response.error(err)
})
});
request.params is equal to a dictionary {"username":inputUsernameHere}.
