NextJS + Firebase Tutorial 🔥 // Hooks, Firestore, Authentication & Functions!

[@JarrodWatts]

Hey Everyone! Important note for those starting out a new Firebase project below. This video is using the v8 version of Firebase. Google has recently released a v9 version of Firebase that is more modular and optimized. You can still follow along this tutorial, a lot of it is still relevant. However some of the code snippets you'll find will be slightly different/outdated, with the new v9 version of Firebase.

[@hirosyee]

What are changes you already know ??

[@yellowbonbon1]

@@hirosyee same question

[@JohnBuildWebsites]

FirebaseUI is incompatible with v9 version of firebase

[@JohnBuildWebsites]

@Bagshot Thanks - I had similar issues trying to follow this tutorial so thought best to share. Glad it was worth the time.

[@RawFatGod]

Thanks for letting us know.

[@outis99]

Honestly mate this is so good, a fast and concise video I can revisit whenever I want to start a new Next/Firebase project. Personally I love this fast informative videos like Fireship does but I imagine they require a lot of editing so don't feel pressure to make all of them like this

[@JarrodWatts]

Thanks so much! Definitely takes a bit of time to edit them together, but I have taken a lot of inspiration from Fireship as I love his style of videos too :)

Getting error - Module not found: Can't resolve firebaseui/StyledFirebaseAuth when I follow these steps

[@cryptodev2615]

I get a SyntaxError: Cannot use import statement outside a module error when deploying functions

[@markyun8606]

I am having same error, have you find out a solution?

[@alexwarendh]

Jarrod! Amazing video! I'm starting to find "my" stack and this is spot on.

[@JarrodWatts]

Thanks so much Alexander! It's such a fun stack to work with, I'm using it for my current project as well, hoping to make some more firebase + Next.js content soon too!

[@alexwarendh]

@@JarrodWatts Looking forward to even more content! I really appreciate the saas perspective of it all as well.

This is already out of date in 2023: error - TypeError: Cannot read properties of undefined (reading 'apps')

[@GungooseHonk]

I wonder if exposing envs with api keys to the browser via NEXT_PUBLIC prefix is a good idea. It will be inlined in your JS bundle and thus available for public eyes. Without this prefix it won't work tho. Any idea how to handle this issue?

[@No_Name_Found_1]

Running into the same issue. You can use JWT in the middleware to generate your own access token and using this in the application but will lose tha ability to use Google SIgn In ect...

[@isadarc11]

Great video! thanks so much! you covered so much in such a little amount of time!

[@thekanimation]

This was fantastic. Thanks a lot

[@IvanKleshnin]

4:05 NEXT_PUBLIC_* vars are available in the browser - that's the whole purpose of prefixing them with NEXT_PUBLIC_.

[@williambjork2777]

@4:14 Are you using some sort of key command/plugin to convert the config values into Next config values when pasting into the env.local file? Or did you just edit the video or am i a complete idiot? (bit of both perhaps)

[@Nano-hb5kf]

have you find out? i'm in the same situation😂

[@williambjork2777]

@@Nano-hb5kf Dont remember lol. But pretty sure I just wrote the env variables by hand and copied the values from my firebase account one by one

Right to the point! amazing. Good job Jarrod! Thanks for sharing it.

Great video man. Surely helped a lot, thanks.

why did you use cloud functions for signup? couldn't you "manually" create a document when user clicks on the sign up button?

Thank you so much Jonathan! That has made my day :-)

Thanks so much for the video!

[@shawn-skull]

Ok. Chat GPT solved in a second all the issues about the outdated stuff related to firebase and FirebaseUI for me. What I don't understand yet is why you used functions to manage the users collection. Is it there any particular reason to do it so? Isn't not secure to handle it like the votes collection?

[@guilhermemoraferia]

Great video, I keep getting this error if anyone could help me: ReferenceError: Cannot access '__WEBPACK_DEFAULT_EXPORT__' before initialization webpack default export being firebase at firebaseClient

I also get this error and have no idea what to do. Did you figure it out?

[@guilhermemoraferia]

@@daylightismine1718 I sort of magically started working after a while idk why, maybe it had something todo with cache or sm, what I suggest is you try and restart your PC, that might work.

No idea why so many people add the user to the db client side. Fb functions is the best way to do this well done.

Best tutorial on youtube

[@momenwadood1342]

Thanks for the video, how to pre render the votes list using SSR after each vote?

[@chinmayabisoi3890]

A question though, why do we need cloud function to create user? We can simply create it like we were doing for vote document right?

[@theceohq]

You could, but it's not recommended. The main reason is that you risk exposing your database configuration and credentials to end-users if you create it via the front-end. Additionally, cloud functions allow you to trigger other side-effects, sanitise/format user data, etc.

Hey Jarrod I just came across an article about how this current method exposes our env to browser which isn't secure. Is there any secure method to do so?

Hey would you mind sending me the article for me to take a look at?

Nice tutorial but understand that you can’t deploy nextjs app into firebase hosting or is there a way? Alternative to publish the app?

[@spencersablan8765]

Vercel

[@bobbyLovesTech]

Thank you so much!!!

How could I do it so that I use one button instead of two. Like a heart button for example. A ternary statement that if the user has "no" you turn it yes and vice versa. edit : I just figured it out. My next problem is that I'm using this method to make likes on some cards. The thing is that each card is unique. This method makes all card have the like... any way I can make them different?

[@tomascarignano5002]

Hi Jarrod! I need your help big time mate. I recently tried to deploy my app to vercel, but I got an error. This error is because when I perform the deploy, vercel goes and looks at my /functions/ directory, tries to build, and cannot find a module in /functions/src/index.ts, because of course it's not present in /package.json Anyhow, appart from the obvious solution of git ignoring the functions directory, so that vercel wouldn't even look at it, I would like to know if there's a proper solution to this, and I think you might know one since I saw in your project's repo that you are, in fact, pushing the functions/ directory to github, and therefore deploying with vercel with it. Thanks so much in advance!

Upto Auth - so far so good. Except, if you have 'Block 3rd party Cookies' set in Chrome Settings you cannot login with either Github or Google in my case.

Good to hear Matthew! That's an interesting point, would you normally have 3rd party cookies disabled for blocking tracking/ads?
