    Due to some updates on firebase you can't import firebase like this (import firebase from 'firebase/app') anymore,
    rather use this ( import firebase from 'firebase/compat/app' ).
    Same for auth ( import 'firebase/compat/auth' )

    If you are getting 'Firebase: Error (auth/invalid-api-key)', this is caused by your react app not detecting your '.env.local' file. For some reason, this file needs to be placed in the root directory of your app instead of the '.src' folder.
    Also, in the latest version of react, 'Switch' has been replaced by 'Routes' and you can not use the 'component' prop anymore. It must replaced with 'element' as such:

    Also, 'useHistory()' is replaced by 'useNavigate()'. Use 'const navigate=useNavigate()' and 'navigate('/')' instead of 'const history=useHistory()' and 'history.push('/')'.
    'Redirect' has been replaced by 'Navigate'.

    42:48 for anyone stuck with the private route on v6, routes and route components have since changed so this won't work. Also the "Redirect" component will not work. Instead use this for your private route:
    import React from "react";
    import { Navigate } from "react-router-dom";
    import { useAuth } from "../contexts/AuthContext";
    export default function PrivateRoute({ children }) {
    const { currentUser } = useAuth();
    return currentUser ? children : ;
    }
    Then this for the dashboard element in your app.js:

    If you have a error with the Switch Module you need to rename it. In the newer react-router-dom versions it was renamed from "Switch" to "Routes" and you have to declare the Route differently now. Instead of " you have to write:
    "

    For anyone having troubles with getting the database url, just leave it blank if it isn't provided by firebase on setup. I'm not entirely sure how it works, but it think it's for the real-time database or something but if you don't have one setup you can just leave the field blank like this:
    REACT_APP_FIREBASE_DATABASE_URL= with no quotations for a string or anything. Please lmk if this doesn't work or if you have a better understanding, I would love to hear.

    Hi, just a small question.
    When using react-router-dom, you have 2 options in regards to "history". You can get access to it and use it using the "useHistory" hook like Kyle does in the video.
    However, you can also just pass it down as a component prop:
    const Signup = ({history}) => {etc ...}
    My question is if there's any substantial difference between the two or if it's just a matter of preference. I'd be grateful if anyone could share their knowledge/thoughts on this.

To fix, cancel all subscriptions and asynchronous tasks in a useEffect cleanup function."

    some updates to the video (and Im sure Im missing more):
    1. Instead of import firebase from 'firebase/app' use import firebase from firebase/compat/app (use same 'firebase/compat' structure for other configuration variables from firebase)
    2. In App.js code, switch component has been replaced by Routes within react-router-dom.
    3. Similarly, use instead of
    4. The hook useHistory is no longer supported by react-router-dom, instead, it is usenavigate. (also, no need to use the .push() function. You can use it directly).
    I will keep adding more as I find/remember.

    • @SaulLee66

      Kyle has a video about useRef. Basically, it's very similar to useState. But when the value store in useRef, the component will not re-render if the value has changed. And it's popular to use it to reference a HTML element.

    If anybody gets a memory leak from trying to set a state on an unmounted component in Signup or Login, its because of the setLoading(false) being at the bottom handleSubmit functions which is after you are pushing to a new page. Just move the setLoading(false) be before the history.push.

      I think it is because in the try {} block you have "history.push('/')" that redirects you to Dashboard component and then you try to set "setLoading state" to the Login component that now is unmounted.

    if I'm not doing something wrong:
    using setLoading(false) in finally gives warning on console. because we try to update state after using history.push. - after unmounting
    instead of doing setLoading(false) in finally (also at the end of an async function) we can do it inside .then before history.push and .catch (also for async functions int try-catch blocks in try before history.push and in catch)
