My current experiment:
I want user to sign in and enter details
When next time he signs in, i want to retrieve his saved information
My intended database structure:
-"users
------"uid"
-----------firstName
-----------lastName`
I use the below code in flutter to create records:
await FirebaseAuth.instance.signInWithEmailAndPassword( email: email, password:
password).then((value)
{
if(value.user.uid != null )
{
final dbRef = FirebaseDatabase.instance.reference().child('users');
dbRef.push().child(user.uid.toString()).set(User().toJson());
}
}
the data gets created with a push key/ID inbetween:
-users
------MFvvXpeRmoQvXkd5VS8 `<---Push ID generated by Firebase`
--------------k8IL4xLQKRf82dxlXNLSHEt2
-----------------------firstName: "sadsadda"
------------------------lastName: "asdsadsad"`
Based on documentations, When i try to retrieve the data using the following code:
final dbRef = FirebaseDatabase.instance.reference().child('users').child(user.uid.toString());
dbRef.equalTo(user.uid.toString()).once().then((snapshot)
{
/*snapshot has value null
}
);
//I even added listener<br>
dbRef.onChildAdded.listen((event) {
readUserInfo(event.snapshot); // even here snapshot value is null.
});
Just for testing purpose, i tried to pass the push key in-between by hardcoding,
final dbRef = FirebaseDatabase.instance.reference().child('users').child('-
MFvvXpeRmoQvXkd5VS8').child(user.uid.toString());`
then "onChildAdded" listener was able to pickup the child entries.
Is this the expected behaviour ? or is there a way to avoid this randomly generated push id?
Thanks for your time in advance
To write the user data under their UID, don't call push(), but simply do:
dbRef.child(user.uid.toString()).set(User().toJson());
To then read the data for the user back, use:
final dbRef = FirebaseDatabase.instance.reference().child('users').child(user.uid.toString());
dbRef.onValue.listen((event) {
readUserInfo(event.snapshot);
});
The .childAdded is needed when you want to read a list of child nodes, for example to read all users:
final dbRef = FirebaseDatabase.instance.reference().child('users');
dbRef.onChildAdded.listen((event) {
readUserInfo(event.snapshot);
});
I'm newbie to Firestore. Firestore docs says...
Important: Unlike "push IDs" in the Firebase Realtime Database, Cloud Firestore auto-generated IDs do not provide any automatic ordering. If you want to be able to order your documents by creation date, you should store a timestamp as a field in the documents.
Reference: https://firebase.google.com/docs/firestore/manage-data/add-data
So do I have to create key name as timestamp in document? Or created is suffice to fulfill above statement from Firestore documentation.
{
"created": 1534183990,
"modified": 1534183990,
"timestamp":1534183990
}
firebase.firestore.FieldValue.serverTimestamp()
Whatever you want to call it is fine afaik. Then you can use orderByChild('created').
I also mostly use firebase.database.ServerValue.TIMESTAMP when setting time
ref.child(key).set({
id: itemId,
content: itemContent,
user: uid,
created: firebase.database.ServerValue.TIMESTAMP
})
Use firestore Timestamp class, firebase.firestore.Timestamp.now().
Since firebase.firestore.FieldValue.serverTimestamp() does not work with add method from firestore. Reference
For Firestore
ref.doc(key).set({
created: firebase.firestore.FieldValue.serverTimestamp()
})
REALTIME SERVER TIMESTAMP USING FIRESTORE
import firebase from "firebase/app";
const someFunctionToUploadProduct = () => {
firebase.firestore().collection("products").add({
name: name,
price : price,
color : color,
weight :weight,
size : size,
createdAt : firebase.firestore.FieldValue.serverTimestamp()
})
.then(function(docRef) {
console.log("Document written with ID: ", docRef.id);
})
.catch(function(error) {
console.error("Error adding document: ", error);
});
}
All you need is to import 'firebase' and then call
firebase.firestore.FieldValue.serverTimestamp() wherever you need it. Be careful with the spelling though, its "serverTimestamp()". In this example it provides the timestamp value to 'createdAt' when uploading to the firestore's product's collection.
That's correct, like most database, Firestore doesn't store creation times. In order to sort objects by time:
Option 1: Create timestamp on client (correctness not guaranteed):
db.collection("messages").doc().set({
....
createdAt: firebase.firestore.Timestamp.now()
})
The big caveat here is that Timestamp.now()uses the local machine time. Therefore, if this is run on a client machine, you have no guarantee the timestamp is accurate. If you're setting this on the server or if guaranteed order isn't so important, it might be fine.
Option 2: Use a timestamp sentinel:
db.collection("messages").doc().set({
....
createdAt: firebase.firestore.FieldValue.serverTimestamp()
})
A timestamp sentinel is a token that tells the firestore server to set the time server side on first write.
If you read the sentinel before it is written (e.g., in a listener) it will be NULL unless you read the document like this:
doc.data({ serverTimestamps: 'estimate' })
Set up your query with something like this:
// quick and dirty way, but uses local machine time
const midnight = new Date(firebase.firestore.Timestamp.now().toDate().setHours(0, 0, 0, 0));
const todaysMessages = firebase
.firestore()
.collection(`users/${user.id}/messages`)
.orderBy('createdAt', 'desc')
.where('createdAt', '>=', midnight);
Note that this query uses the local machine time (Timestamp.now()). If it's really important that your app uses the correct time on the clients, you could utilize this feature of Firebase's Realtime Database:
const serverTimeOffset = (await firebase.database().ref('/.info/serverTimeOffset').once('value')).val();
const midnightServerMilliseconds = new Date(serverTimeOffset + Date.now()).setHours(0, 0, 0, 0);
const midnightServer = new Date(midnightServerMilliseconds);
The documentation isn't suggesting the names of any of your fields. The part you're quoting is just saying two things:
The automatically generated document IDs for Firestore don't have a natural time-based ordering like they did in Realtime Database.
If you want time-based ordering, store a timestamp in the document, and use that to order your queries. (You can call it whatever you want.)
This solution worked for me:
Firestore.instance.collection("collectionName").add({'created': Timestamp.now()});
The result in Cloud Firestore is:
Cloud Firestore Result
Try this one for Swift 4 Timestamp(date: Date())
let docData: [String: Any] = [
"stringExample": "Hello world!",
"booleanExample": true,
"numberExample": 3.14159265,
"dateExample": Timestamp(Date()),
"arrayExample": [5, true, "hello"],
"nullExample": NSNull(),
"objectExample": [
"a": 5,
"b": [
"nested": "foo"
]
]
]
db.collection("data").document("one").setData(docData) { err in
if let err = err {
print("Error writing document: \(err)")
} else {
print("Document successfully written!")
}
}
The way it worked with me, is just taking the timestamp from the snapshot parameter snapshot.updateTime
exports.newUserCreated = functions.firestore.document('users/{userId}').onCreate(async (snapshot, context) => {
console.log('started! v1.7');
const userID = context.params['userId'];
firestore.collection(`users/${userID}/lists`).add({
'created_time': snapshot.updateTime,
'name':'Products I ♥',
}).then(documentReference => {
console.log("initial public list created");
return null;
}).catch(error => {
console.error('Error creating initial list', error);
process.exit(1);
});
});
I am using Firestore to store data that comes from a Raspberry PI with Python. The pipeline is like this:
Raspberry PI (Python using paho-mqtt) -> Google Cloud IoT -> Google Cloud Pub/Sub -> Firebase Functions -> Firestore.
Data in the device is a Python Dictionary. I convert that to JSON.
The problem I had was that paho-mqtt will only send (publish) data as String and one of the fields of my data is timestamp. This timestamp is saved from the device because it accurately says when the measurement was taken regardless on when the data is ultimately stored in the database.
When I send my JSON structure, Firestore will store my field 'timestamp' as String. This is not convenient. So here is the solution.
I do a conversion in the Cloud Function that is triggered by the Pub/Sub to write into Firestore using Moment library to convert.
Note: I am getting the timestamp in python with:
currenttime = datetime.datetime.utcnow()
var moment = require('moment'); // require Moment
function toTimestamp(strDate){
return parsedTime = moment(strDate, "YYYY-MM-DD HH:mm:ss:SS");
}
exports.myFunctionPubSub = functions.pubsub.topic('my-topic-name').onPublish((message, context) => {
let parsedMessage = null;
try {
parsedMessage = message.json;
// Convert timestamp string to timestamp object
parsedMessage.date = toTimestamp(parsedMessage.date);
// Get the Device ID from the message. Useful when you have multiple IoT devices
deviceID = parsedMessage._deviceID;
let addDoc = db.collection('MyDevices')
.doc(deviceID)
.collection('DeviceData')
.add(parsedMessage)
.then ( (ref) => {
console.log('Added document ID: ', ref.id);
return null;
}).catch ( (error) => {
console.error('Failed to write database', error);
return null;
});
} catch (e) {
console.error('PubSub message was not JSON', e);
}
// // Expected return or a warning will be triggered in the Firebase Function logs.
return null;
});
Firestone method does not work. Use Timestamp from java.sql.Timestamp and don't cast to string.. Then firestone formats it properly. For example to mark a now() use:
val timestamp = Timestamp(System.currentTimeMillis())
multiple ways to store time in Firestore
firebaseAdmin.firestore.FieldValue.serverTimestamp() method. The actual timestamp will be computed when the doc is written to the Firestore.
while storing it looks like this:
firebaseAdmin.firestore.Timestamp.now() method.
while storing it looks like this:
For both the methods, next time you fetch data it will return Firestore Timestamp object:
So, you first need to convert it to native js Date object and then you can perform methods on it like toISOString().
export function FStimestampToDate(
timestamp:
| FirebaseFirestore.Timestamp
| FirebaseFirestore.FieldValue
): Date {
return (timestamp as FirebaseFirestore.Timestamp).toDate();
}
Store as unix timestamp Date.now, it'll be stored as number i.e. 1627235565028 but you won't be able to see it as readable Date in firestore db.
To query on this Firestore field, you need to convert the date to timestamp and then query.
Store as new Date().toISOString() i.e. "2021-07-25T17:56:40.373Z" but you won't be able to perform date range query on this.
I prefer the 2nd or 3rd way.
According to the docs, you can "set a field in your document to a server timestamp which tracks when the server receives the update".
Example:
import { updateDoc, serverTimestamp } from "firebase/firestore";
const docRef = doc(db, 'objects', 'some-id');
// Update the timestamp field with the value from the server
const updateTimestamp = await updateDoc(docRef, {
timestamp: serverTimestamp() // this does the trick!
});
Sharing what worked for me after googling for 2 hours, for firebase 9+
import { serverTimestamp } from "firebase/firestore";
export const postData = ({ name, points }: any) => {
const scoresRef = collection(db, "scores");
return addDoc(scoresRef, {
name,
points
date: serverTimestamp(),
});
};
Swift 5.1
...
"dateExample": Timestamp(date: Date()),
...
The newest version from Firestore you should use it as follow
import { doc, setDoc, Timestamp } from "firebase/firestore";
const docData = {
...
dateExample: Timestamp.fromDate(new Date("December 10, 1815"))
};
await setDoc(doc(db, "data", "one"), docData);
or for sever timestamp
import { updateDoc, serverTimestamp } from "firebase/firestore";
const docRef = doc(db, 'objects', 'some-id');
const updateTimestamp = await updateDoc(docRef, {
timestamp: serverTimestamp()
});
In the example below, is there a way to get the uid of the user who wrote to /messages/{pushId}/original?
exports.makeUppercase = functions.database.ref('/messages/{pushId}/original')
.onWrite(event => {
// Grab the current value of what was written to the Realtime Database.
const original = event.data.val();
console.log('Uppercasing', event.params.pushId, original);
const uppercase = original.toUpperCase();
// You must return a Promise when performing asynchronous tasks inside a Functions such as
// writing to the Firebase Realtime Database.
// Setting an "uppercase" sibling in the Realtime Database returns a Promise.
return event.data.ref.parent.child('uppercase').set(uppercase);
});
UPDATED ANSWER (v1.0.0+):
As noted in #Bery's answer above, version 1.0.0 of the Firebase Functions SDK introduced a new context.auth object which contains the authentication state such as uid. See "New properties for user auth information" for more details.
ORIGINAL ANSWER (pre v1.0.0):
Yes, this is technically possible, although it is not currently documented. The uid is stored with the event.auth object. When a Database Cloud Function is triggered from an admin situation (for example, from the Firebase Console data viewer or from an Admin SDK), the value of event.auth is:
{
"admin": true
}
When a Database Cloud Function is triggered from an unauthenticated reference, the value of event.data is:
{
"admin": false
}
And finally, when a Database Cloud Function is triggered from an authed, but not admin, reference, the format of event.auth is:
{
"admin": false,
"variable": {
"provider": "<PROVIDER>",
"provider_id": "<PROVIDER>",
"user_id": "<UID>",
"token": {
// Decoded auth token claims such as sub, aud, iat, exp, etc.
},
"uid": "<UID>"
}
}
Given the information above, your best bet to get the uid of the user who triggered the event is to do the following:
exports.someFunction = functions.database.ref('/some/path')
.onWrite(event => {
var isAdmin = event.auth.admin;
var uid = event.auth.variable ? event.auth.variable.uid : null;
// ...
});
Just note that in the code above, uid would be null even if isAdmin is true. Your exact code depends on your use case.
WARNING: This is currently undocumented behavior, so I'll give my usual caveat of "undocumented features may be changed at any point in the future without notice and even in non-major releases."
Ever since Firebase functions reached version 1.0, this behavior is no longer undocumented but has sligtly changed. Be sure to read the docs.
Context has been added to cloud functions and you can use it like this
exports.dbWrite = functions.database.ref('/path/with/{id}').onWrite((data, context) => {
const authVar = context.auth; // Auth information for the user.
const authType = context.authType; // Permissions level for the user.
const pathId = context.params.id; // The ID in the Path.
const eventId = context.eventId; // A unique event ID.
const timestamp = context.timestamp; // The timestamp at which the event happened.
const eventType = context.eventType; // The type of the event that triggered this function.
const resource = context.resource; // The resource which triggered the event.
// ...
});
After a user logs in using $firebaseAuth, Google sends the user's displayName, email, and photoURL. I then want to look up the user's account in my Firebase database. I can't use $getRecord(key) because Google doesn't tell me the user's key. It appears that I should use $keyAt(recordOrIndex), and then use $getRecord(key). $keyAt(recordOrIndex) works fine with an index. $keyAt(recordOrIndex) works fine with a record that I retrieved with $getRecord(key). I can't get $keyAt(recordOrIndex) to work with an object that I made from the user data that Google returned using $firebaseAuth.
I tried both the complete object (displayName, email, photoURL) and an object consisting of only the email address. The latter is what I would prefer to use. Neither worked.
app.controller('LoginModalInstanceCtrl', ['$scope', '$location', '$uibModalInstance', '$firebaseArray', '$firebaseObject', '$firebaseAuth', function($scope, $location, $uibModalInstance, $firebaseArray, $firebaseObject, $firebaseAuth) {
// Create Firebase3 reference
var ref = firebase.database().ref();
// Set up Firebase Auth
$scope.authObj = $firebaseAuth();
var authData = $scope.authObj.$getAuth();
$scope.authData = authData;
// Google OAuth login handler
$scope.loginGoogle = function() {
$scope.authData = null;
$scope.error = null;
$scope.authObj.$signInWithPopup("google")
.then(function(authData) {
$scope.authData = authData;
console.log(authData);
console.log("Your displayName is:", authData.user.displayName);
console.log("Your email is:", authData.user.email);
console.log("Your photoURL is:", authData.user.photoURL);
var record = {
displayName: authData.user.displayName,
email: authData.user.email,
photoURL: authData.user.photoURL
};
var emailObject = {
email: authData.user.email
};
// look up account
var users = $firebaseArray(ref.child('users'));
users.$loaded()
.then(function() {
console.log("Array loaded!");
var key1 = users.$keyAt(1);
console.log(key1); // -Khi6OxAo339ye6xoG3i
var record = users.$getRecord(key1);
console.log(record); // Object with displayName, email, and photoURL
var key1 = users.$keyAt(record);
console.log(key1); // -Khi6OxAo339ye6xoG3i
var objectKey = users.$keyAt(object);
console.log(objectKey); // null
var emailKey = users.$keyAt(emailObject);
console.log(emailKey); // null
});
$uibModalInstance.close(); // close modal window
$location.path('/languagetwo/'); // return to the homepage
}).catch(function(error) {
console.error("Authentication failed:", error);
});
};
Should I use $firebaseObject instead of $firebaseArray:
var user = $firebaseObject(ref.child('users').child( SOMETHING HERE? ));
The answer appears to be no, you can't search Firebase Database using AngularFire. (Maybe AngularFire 2 has search, I didn't look.) What I did instead was to use "plain vanilla" Firebase:
var users = firebase.database().ref('users');
users.orderByChild('email').equalTo(authData.user.email).once('value').then(function(snapshot) {
console.log(snapshot.val());
});
The first line sets up the Firebase ref and is the similar to as before, except that I'm going straight to the users array, instead of using $FirebaseArray to get to the users array.
The second line is a completely different syntax. First, you have to specify the order that you want the returned object to be in. Yes, it returns an object, not an array. I tried snapshot.val().length() and found that it's not an array. What orderByChild('email') does is to access the 'email' property of the objects in the 'users' array.
Next we do the query. equalTo(authData.user.email) returns only the objects in which the email address from $FirebaseAuth equals the email address in our 'users' array.
Next, once('value') creates a promise and waits for the async data. I tried using on() but couldn't get it to work, too many arguments or something. once() requires an argument, which can be value, child_added, child_changed, child_removed, or child_moved. The value argument is for getting data from a location without changing the child nodes.
We can then set up our then promise fulfillment. You can call the returned data anything. Here it's called snapshot.
Lastly snapshot.val() provides the data from the database, looking just like it does in the Firebase Console.
I'm working on a firebase+angularjs app and I'm using the simple email and password authentication and it's working properly.
I'm just wondering if I can add extra user data on the user table which is being used by firebase email+password auth, like I want to add billing info and other details concerning the user without creating extra node/table on firebase to store these extra data.
Firebase stores the email/password users in a separate location, that you don't have direct access to. You cannot expand the data in this location.
Since many application developers want to access the user data in their application code, it is a common practice to store all users under a /users node inside the application database itself. The disadvantage is that you have to do this yourself. But the positive side of this is that you can store any extra information if you want.
See the Firebase guide on storing user data for sample code. From there:
var ref = new Firebase("https://<YOUR-FIREBASE-APP>.firebaseio.com");
ref.onAuth(function(authData) {
if (authData && isNewUser) {
// save the user's profile into Firebase so we can list users,
// use them in Security and Firebase Rules, and show profiles
ref.child("users").child(authData.uid).set({
provider: authData.provider,
name: getName(authData)
});
}
});
NOTE: This method only works if you are using Firebase Admin SDK and you need to have end point on your server to manage custom tokens
Firebase Admin SDK has an option to create custom tokens with additional claims object, which can contain arbitrary data. This might be useful to store some user related info, like whether the user is premium user or not.
Additional claims data is accessible using auth object.
example
var uid = "some-uid"; //this can be existing user UID
var additionalClaims = {
premiumAccount: true,
some-user-property: 'some-value'
};
admin.auth().createCustomToken(uid, additionalClaims)
.then(function(customToken) {
// Send token back to client
})
.catch(function(error) {
console.log("Error creating custom token:", error);
});
additionalClaims are also accessible in Firebase security rules.
for more info read Firebase Custom Tokens
A Firebase User has a fixed set of basic properties—a unique ID, a primary email address, a name and a photo URL—stored in the project's user database, that can be updated by the user (iOS, Android, web). You cannot add other properties to the Firebase User object directly; instead, you can store the additional properties in your Firebase Realtime Database.
Firebase has a fixed set of user properties which can be updated but not added on to.
However you can add small amounts of data with the help of serialization and deserialization using JSON.stringify() and JSON.parse()
And then use any one of the unused properties to store the string
either in DisplayName, or photoURL property.
Keep in mind the data that can be added has to be small in size and stored as a string.
And this can be only possible with using the method in the FIREBASE SDK and not the angularfire as illustrated below
var user = firebase.auth().currentUser;
user.updateProfile({
displayName: "Jane Q. User",
photoURL: "https://example.com/jane-q-user/profile.jpg"
}).then(function() {
// Update successful.
}, function(error) {
// An error happened.
});
You could store more json like data in the photoURL or displaYName variable in the form of string here.
My answer is not angular related but I searched quiet a bit to find out how to do it using Polymer and Polymerfire so I add this answer to help people get it done faster than i did.
I had to add a separate node to db as Frank van Puffelen mentioned.
Imports:
<link rel="import" href="../bower_components/polymerfire/firebase-app.html">
<link rel="import" href="../bower_components/polymerfire/firebase-auth.html">
<link rel="import" href="../bower_components/polymerfire/firebase-document.html">
Then place anywhere in your app a <firebase-app> component:
<firebase-app
name="yourAppName"
api-key= "{{yourApi}}"
auth-domain= "{{yourAuthDomain}}"
database-url= "{{yourDbUrl}}"
>
</firebase-app>
After that you will need to use <firebase-auth> and <firebase-document>:
Template :
<firebase-auth
id="auth"
app-name="yourAppName"
signed-in="{{signedIn}}"
user="{{user}}">
</firebase-auth>
<firebase-document
id="document"
app-name="yourAppName"
path="{{usersPath}}" // e.g "/users"
data="{{userDocument}}">
</firebase-document>
Script:
this._register = function(){
var formValid = this.querySelector('#register-form').validate();
var auth = this.querySelector('#auth');
if(formValid && this.passWordsIdentic){
//The actual registration
auth.createUserWithEmailAndPassword(this.email, this.password).then(function(user){
console.log('auth user registration succes');
//Example values
this.userDocument.uid = user.uid;
this.userDocument.email = user.email;
this.userDocument.firstName = this.firstName;
this.userDocument.lastName = this.lastName;
this.userDocument.userName = this.userName;
this.$.document.save(this.usersPath).then(() => {
console.log("custom user registration succes");
this.$.document.reset();
});
}.bind(this)).catch(function(error) {
var errorCode = error.code;
var errorMessage = error.message;
console.log('error: ', errorCode);
);
}
}
And that's it, you may want to take a look at this excellent google codelab which is a good introduction into using firebase with polymer.
Here is the code of registration where add the extra fields in the Users table
import { AngularFireAuth } from "#angular/fire/auth";
constructor(private firebaseAuth: AngularFireAuth){}
registration(data: any, password: any) {
return this.firebaseAuth.auth.createUserWithEmailAndPassword(data.Email, password)
.then(res => {
res.user.updateProfile({
displayName: `${data.DisplayName}`
})
data.UserId = res.user.uid;
data.PhoneNumbers = [{
NumberType: '',
NumberValue: ''
}];
data.PhotoUrl = '';
data.Addresses = [{
AddressLine1: '',
AddressLine2: '',
City: '',
State: '',
Country: '',
PostalCode: '',
AddressType: ''
}];
data.IsDeleted = false;
this.fireStore.doc(`users/${res.user.uid}`).set(data);
this.toastr.success('User has been register successfully!', 'Successfull!');
return true;
}).catch(err => {
switch (err.code) {
case 'auth/email-already-in-use':
this.toastr.error(`Email address ${data.Email} already in use.`, 'Error!');
break;
case 'auth/invalid-email':
this.toastr.error(`Email address ${data.Email} is invalid.`, 'Error!');
break;
case 'auth/operation-not-allowed':
this.toastr.error('Error during sign up.', 'Error!');
break;
case 'auth/weak-password':
this.toastr.error('Password is not strong enough. Add additional characters including special characters and numbers.', 'Error!');
break;
default:
this.toastr.error(err.message, 'Error!');
break;
}
});
}
Here's a swift version. Your user structure ("table") is like
--users:
-------abc,d#email,com:
---------------email:abc.d#email.com
---------------name: userName
etc.
After you pass the auth FIRAuth.auth()?.createUser you can set the users in database as below:
let ref = FIRDatabase.database().reference()
let rootChild = ref.child("users")
let changedEmailChild = u.email?.lowercased().replacingOccurrences(of: ".", with: ",", options: .literal, range: nil) // Email doesn't support "," firebase doesn't support "."
let userChild = rootChild.child(changedEmailChild!)
userChild.child("email").setValue(u.email)
userChild.child("name").setValue(signup.name)
Please note that method is changed in v4.0.0. Therefore, you need to use the below code to retrieve the user profile:
afAuth.authState.subscribe((user: firebase.User) => {
this.displayName = user.displayName;
this.email = user.email;
this.photoURL = user.photoURL;
});
The answer from Frank is good, but things are a little different in Angular6/Firebase5/Angularfire5:
Here is my click handler for signing in a user:
this.afAuth.auth.signInWithPopup(new firebase.auth.GoogleAuthProvider()).then((e) => {
console.log("Log-In Success" + e.additionalUserInfo.profile.name);
if (e.additionalUserInfo.isNewUser)
this.addUserToDatabase(/*...*/);
}).catch((error) => {
console.log("Log-In Error: Google Sign-In failed");
});
