It is generally better practice to host authentication (and especially authentication logic) in the back-end, if not for performance, definitely for security reasons. That said, you can avoid using cloud functions for this authentication with firebase! Here is an alternative super simple video tutorial you may like instead from Fireship: [this video] . The Google Firebase YouTube channel [LINK] also has many videos on the subject. Cloud functions are useful for when you want parallel action to be taken in the back-end during or after login, while the useAuthState() [LINK] react hook is great for when you want parallel action to be taken in the front-end during or after login.

I decided to create a firebase messaging app based off of the video: [this video] And so far I can get the ui up, just when I type in a message and hit the enter button it displays: [LINK] And I think it has something to do with one of the fields not returning a value, but I don't know what fields aren't returning a value. Probably something to do with the message idk. I have put previously: firestore.settings({ ignoreUndefinedProperties: true }); into there and it doesn't crash when I do that, but then I can't send a message. Here is my App.Js code (note: I haven't done javascript previously) import React, { useRef, useState } from 'react'; import './App.css'; import firebase from 'firebase/app'

I am writing a code watching this video from Fireship.io ( [this video] ) to build a chatapp using Firestore and using Google Auth in Firebase. I am getting the following error. I know that the video is a bit outdated so please help me out with this one!! Error Message: [eslint] src\App.js Line 26:16: React Hook "useAuthState" cannot be called at the top level.

I was following Fireship's building chat app video [this video] (this part is around 3:30-4 minutes) but I am trying do something different, just using it for oauth and database setup help. I made a simple database on it, then tried to follow the query format where the collection grab and query seem to work fine since I can console.log them. But when I try to use the collection data, it is undefined. I also found another post on here similar that queried it differently and tried to use an grab a specific variable, but doing that just left me with an error saying "query2 is not a function". So below I added 2 versions of what I tested. ListItem is the collection name, and checked is one of my vari
