Authenticate Your Next.js Apps Using Firebase: Complete Guide

[@eugenebesedovsky]

To prevent a home page to flash just use 'return router.push("...")' instead of 'router.push("...")'. Thus you won't see the home page if you're not signed in. Also can use 'loading' variable coming second from useAuthState hook to render some fallback component. So there won't be any need of adding session storage item.

Thanks for sharing this guide! You made a comment about making errors toward the end of the video. I just came here to say that I was looking for this video, and there were a few available... but the other ones I looked at were guys that jump-cut through their mistakes, and they'd copy and paste all of their code so you wouldn't see them typing. Those videos are awful to follow along with. Yours is relatable. Keep doing it the way you're doing it! We're here because we're making mistakes too.

[@coderyan]

Thank you for the kind words, very much so appreciated!

Thank you for the video, App Router and Firebase was a headache until now

[@coderyan]

Happy it helped!

This is definitely one of the best tutorials I've watched Easy to understand and literally solved an issue I thought would take me hours in such a short time. Thanks!

[@coderyan]

Happy to hear it! Thank you

[@MrBlazzerBoy]

Also please do one for protecting routes: show those pages only if user is logged in.

[@ukaszStrzelecki]

Hi Ryan! Thanks for this tutorial. Can you make full example how to use Firebase Auth also using SSR and proper session storage thru whole application? There is a lot of this kind of tutorials were you can find examples how to signin/login/signout but it ends at this step. Thanks a lot!

[@ionutsandu5913]

I successfully managed to do what you're asking for my company but it was quite tricky. This weekend I will create a repo if you'd like so you can get some help from there.

[@alexandergeorgesquire220]

Hey thanks Ryan Just wondering... Why are you using .env for the config files? The docs say the cofnig data is safe to be on the front end?

[@yashraj4855]

Awesome guide! Got my thing working in one go. Thanks a lot 😊.

[@Growingmindsetalha]

it is not adding the user in the data base

[@cohena100]

when creating the app and when i choose Yes on Would you like to use `src/` directory then it doesn't work. any idea why?

[@phptempaltedf]

it's full ClientSide when we use Firebase auth?

[@isagive]

Thank you brother. the userSession solution seems wrong - the useAuthState changes so maybe we need to wrap in a function and wait for it? i dont know but it still kicks out a lot of error after routing. In anycase, thank you for the hard work very helpfull tutorial

[@Robert-gr1cl]

beautiful tutorial, worked perfectly for me!

How can I refresh the user idToken after expiration? How is that process? After 1 hour, the user is not retrieved and no refreshed id is gotten. Please, I'm really stuck in that process 🙏. I'm building a PWA with NextJS and I need the user to always be signed in

[@treasuredev]

Nice, but if you create a nextapi to handle functions from the backend, it logs users out after ah hour. I don't want to call my config from client side. I want to handle everything in next api functions

[@Robert-gr1cl]

if i refresh the page on the home screen it logs me out (i did this exactly the same) why is that?

[@lucasrodrigues680]

Thank you for the guide. It helped me a lot! The only issue that I had was the errors. The react-firebase-hook did not throw some of my errors automatically. I had to get the errors from the hook and then throw it manually. Something like this: const [signInWithEmailAndPassword, user, loading, error] = useSignInWithEmailAndPassword(auth) try { const res = await signInWithEmailAndPassword(data.email, data.password) if(error){ throw new Error(error.message) } reset() router.push('/my-chats') } catch(err) { console.error(err) }

[@priyapandey8951]

Can't we directly use the config js file for the storing values of those variables? Why are we using them as env variables? Is it some kind of convention to do so?

[@nosrehcorporation]

Safety, you dont want to expose those values in your regular packages

[@priyapandey8951]

@@nosrehcorporation ok thankyou sir

[@brookt5725]

Have you tried going to / without signing in it displays the content for a short while which is really bad thing

[@coderyan]

Should have covered this in the video, but can be solved in several ways, one of which is by using some loading state

[@brookt5725]

@@coderyan Wouldn't that be redundant to do that on each page

[@coderyan]

Wouldn’t need to do it at each page. You can do it higher up in the application (e.g in the root component)

I am getting an error of module not found in page.js file for config.js file for auth. But I have already made that file.

[@pedromendoza8148]

Is this going to make all the app a client component?

[@Fluttydev]

is this secured to store use in session storage ?

[@Minu_Shalom]

Hi Ryan! Maybe I'm wrong, but as I know NEXT_PUBLIC will be included in the client-side JavaScript bundle, making them accessible to anyone who can inspect the website's source code.

[@fluffsenpai]

The home page still flashes when going to the original URL. if the page was to be protected its not.

Thankyou soo much. Its working 😍🥰

My problem is that there is no code written in SignIn.js file that checks the databse for users and then signs them in, it just creates a new user in signIn itself, removing the need for signup and leading to multiple entries of same users everytime they login

[@andreschavez3929]

Thats wrong because you can only have one user with the same email in firebase auth

[@StatsOverStyles]

that was awesome and so easy to use

yes, this is okay only if you're using firebase as database since firebase will handle backend protection via security rules.

… Oh. So I have to use hooks and shit… alright. That makes my life easier. I’m used to calling some API instead of FireBase and then storing JWTs. So this is kinda weird. And I’m used to working in SolidJS or Svelte. So this is weird for me.
