Hi, my latest course is out now (Professional React & Next.js): bytegrad.com/courses/professional-react-nextjs -- I'm very proud of this course, my best work! I'm also a brand ambassador for Kinde (paid sponsorship). Check out Kinde for authentication and more bit.ly/3QOe1Bh
Do you offer regional discounts like some other authors, taking in account students country? (like South Africa with a very weak Rand to the US Dollar)
this is best nextjs video. Majority of yt is filled with just basic tutorials and it's so hard to find videos like this. Everyone is discussing new Nextjs features instead of actually teaching about features used in Industry.
you are THE ONLY ONE who actually is trying to explain this on examples which aren't complete copies of the documentation together with the same, exactly the same, explanation. I'm so thankful I can't even express this properly in words, it's very frustrating to look for some explanations and just getting these videos with the exact documentation copy paste with 0 info over and over and over again...... man
Well, this video alone is more valuable than most courses about Next.js. Almost all mistakes solved in this video are from real-life struggles and can easily take tons of hours to figure out how to solve them alone! Thank you for the amazing video! I was hesitant to upgrade to Next 15 because of these doubts I had about server/client components. This video helped me a lot. :D
What I love about this video is how you go through each example and insert those "oh, and btw you can also do this this other way, and this will work a little different, which may or may not be better in your use case". That's always what lack in tutorials. Everyryone is teach only one, their, strict way, and if you try to deviate from that for an inch, then everything falls aparat, but they won't tell you that!
Way to get to the f'ng point on every one of these! I typically can't sit through long instructional videos...they're so often filled with fluff. I find myself skipping through them looking for actual content and (typically) giving up. But this was an easy 1hr and 45 to watch every single minute of. Hats off.
This is gold, thank you. Well explained, especially the server/client component differences and woes, such as Hydration errors. Extra Side Note: I rarely, if ever, watch a 2h video tutorial in one go, so kudos for keeping it extremely relevant for Next.js devs :)
Thanks, I made exactly the most of the mistakes you are mentioning here. My problem with "use client" overuse was very painful, as I was getting 429 from the external service that I'm using for auth. The problem was, I was fetching data on the server side but the call went from client component, so through the middleware I had many requests on a single render of a all components, causing 429 on user check and token refresh. A tough lesson learned - I wish I’d seen your video sooner!
"Insightful video! It's no mistake to say this is the #1 Next.js guide for beginners. Your comprehensive rundown cleared the fog surrounding many common misconceptions. Time to level up our digital marketing game with Semaphor analytics. Thank you!"
I have seen quite a lot of NextJS videos on TH-cam and also courses from Udemy. This is the BEST so far. Practical examples to demonstrate the mistakes. And most importantly it rephrases those big terms we see in documentation in a layman way that beginner can understand. Thanks for the video
this is not only the best nextjs video I've watched, it is also one of the best overall programming videos I've ever watched. I can't stress enough how useful this is. thank you so much!!!
bro you are the one and only one kind of a teacher who has explained the concepts like a teacher teaches to kids , minimalistically yet on to the point , I will be buying your course , I am from India and even after the discount price is still high for me , I am gonna save and bring your react next course , please dont stop content like this , your explanations are best , also please start series like this for react and other , Also please start project series , i feel no other teacher can match the style when it comes to build complex apps on youtube , so please go ahead with projects tutorials.
GREAT VIDEO! Giving real world examples that are at the same time generic is best way to convey the knowledge. Even if I often read documentations and articles, I learned a lot of new things from this video and see some of my mistakes from the past, that I resolved but didn't know why was it resolved. THANK YOU for this!
After the first few sections, I ended up watching the entire video. You do an excellent job of providing real world scenarios and examples on the topics, as well as explaining the alternative of your advice. Awesome work
this video is the best out there, I'm happy that I found it, but sad that it took me so long to get to this golden gem. very nice work, hope you keep sharing your knowledge.
I'm just around half way there in the video & feeling like I have watched hours long tutorial. Highly appreciate the content! Highly appreciate your efforts & knowledge! Bundle of thanks!
One of the best video on NextJS doubts which will only arise once you become expert in NextJS after completing FEW videos FEW projects. But your video is so amazing that if any dev will watch it completely will definitely become pro in NextJS and any confusion which used to come when we do large project will be cleared out after watching this, Thanks :) Much love from India.
Nice overview! I have some experience with React and started learning NextJs. Currently, I'm building a full-stack app, and for a front-end I decided to use NextJs. So your video is a good reminder of which mistakes need to be avoided.
Amazing! Awesome! Fabulous! You have explained ALL what all common confusions go on with NextJs. NextJs should include this video in their official guides and help/troubleshoot/Faqs docs. This cleared most of my doubts for which I was not finding a fitting resolutions together combined anywhere else. ❤ Thanks alot #ByteGrad
@@ByteGrad One thing doubt remains, when I have to use header on all page, or authentications , how to make sure not all pages become dynamic rendered? U said middleware word, but that not explained. What is real solution?
Middleware is a special file you create at the root of your next js project. This file is where you put all your authentication logic. Just like loading, error, route and page files have a special meaning in next js, a middleware file would automatically be recognized by next js and would be run by next js before the routes you specify in the matcher of helper function written in your middleware file.
This video is an absolute gem! 🌟 The explanation of the Next.js app router and pages router differences was incredibly clear and helpful. The examples provided on server components and client components really made it easy to understand where to use each. I especially appreciated the deep dive into hydration errors and how to handle them. Keep up the great work! 🚀👏
Слушай, а это все понятно когда мы использует fetch и чистый next js. А что если мой сервер с базой данных находится не в проекте next js. А где то на другом сервере. Я обращаюсь к нему посредством rest api. Я пытаюсь прикрутить в свой next js проект tanstak query. Я думаю что это будет лучшим решением чем то что предлагает next js из коробки. Мне интересно твоё мнение.
I spent last 3 months learning NEXTJs(Switching from react to next) and some things just didn't make sense although I'm pretty good with react. This one video simplified entire Nextjs for me. Thanks a lot brother. I'm eternally grateful.. Now it all makes complete sense.
It's funny cause I just made the mistake of using "use client" wherever I got an error just to get around it without actually understanding it and the first video I get recommended is yours, almost ironic. Thank you so much though this video saved so much time for me with my first project!
What a video. This video covers almost everything about RSC... Thank you... there is one thing left in my head that keeps making me stuck on my project. "where do we save token and refresh token". since my project depends on an external data source that require access token and reguilarly refresh the token with he give refreshToken. In client side, we commonly do it in cookie, and using axios we can pass that token as bearer token, and with the interceptor we refresh the token if necessary. but what is your advice when it comes to server land?
This was one of the best deliveries i have seen outside of dave gray. Will be picking up that course, and hoping it is delivered with the same clarity.
Great video, bro! I learned a lot more than I did from the Next.js documentation because you explained things thoroughly. Thanks a lot for your hard work.
wow man, you need to be ambassdor of vercel, a missile of bottom lines what a implicity sharp gzipped explaination worth every second congratz you pinned as top mentor on next js
wowzers! this was awesome 2 hours! agreed with comments above, mistakes you were showing, was the mistakes i made in a some of my previous projects great job! subscribed!
Not even halfway through. AMAZING. I have learned some of the subtle dance between client and server. Thank you, I thought I was going crazy. Question about your course (React + Next): Do you provide a pattern of Client > Next Auth > Server > Database > Back to Client > Edit/Update/Upsert > Revalidate? Or something close? If not, can I request a paid consultation?
How would you advise using a state management library like zustand to handle, fetch, stored responses, to be used it a page let's say "analytics". You know eventually every component will def be a use client component, since every component needs that stored data. Is it best to ditch the zustand sml and just use the next.js inbuilt async mechanism to fetch those data individually on each components, or ...?
If I have a card component that fetches database data, and this card component needs a zustand state transferred via props, how could it be done? The issue appears when I need client parent component using client state, and loads a child from server component. If I do an API I can solve this because everything will run at the client, but I want to get rid of APIs to connect to the database. thanks!!
Awesome video! I'm a bit confused about "getData" functions and the "use server" directive. We shouldn't place "use server" at the top of a file which has a bunch of "getData" functions, because we are exposing a POST endpoint, and also because calling a "getData" from a server component already make the get in the server. We should use "use server" only to mutations functions, and validate those. Did I get that right?
So I answer myself after some investigation. React recommends to use "server-actions" for mutating. According to React docs "Server Actions are designed for mutations that update server-side state; they are not recommended for data fetching.". You could use it to retrieve information but is not the intended way. Server actions request is a POST, so you will be fetching data with a POST request. I found in a Reddit post this answer: "I asked one of the members of the Vercel team on Discord if we could use server actions to fetch data. While it's possible, they don't encourage this, but the response I got was a bit ambiguous."
This video is super relevant, I learned a lot of things, I found out that I was not validating my server actions, I'll have to address this because I thought that nextjs automatically validated them but now that I think, there's now way that next will know what type things are for validation, this is just a typescript layer. I have to come up with a nice validation strategy for keeping types but knowing that it can be unknow data for server actions.
This video is really good. I’ve just finished reading the docs and you just filled all the blanks in my mind. Btw, what Vs code theme are you using? Thx
I have one question....can you explain the purpose of wrapping a server component with a context provider? Can the context share data to the server component or its just to allow server components to be redered as server? And thank you for this tutorial, it helped me a lot!
if i have product card component that contains the favorite button, should i direct make productCard component 'use client' or create a 'use client' favorite button component and import it in productCard thank you

Video is freakishly helpful. Great job buddy.
Every minute of this video is called "QUALITY CONTENT"
So ~ @23:00 by default it renders all html on the server, which just as a side effect runs any JS, then it hydrates any client component, right?
exactly what i was looking for. keep it up!
Wow sir you are attempting to do those things which other youtube doesn't focus on thank you sir 🥰🥰😍
the useful tutorial video, i hope you can point out more and more common mistakes that developer can make with Next.js project.
Thanks, will do!
so much better than those vercel guys that literally do documentation voiceover as if people can't read
Only about half hour into the video, but already learning a lot. Thank you so much for making this
Thanks. Let's say we got a static render of the products page. Then a new product was added from another admin panel. Do I need to get a rebuild?
What an amazing video. Very clarifying!!

Change the title to Mistakes devs make. I’m not a beginner and you made some great points!
Your course was amazing and your videos are always top tier. I would love it if you could do a database design course/series of videos.

After understanding all, this is a cool way to make project , we have both client and server components available just we have to decide
thank you very much this is a really great masterclass on next.

The learning curve is real, but worth it IMO
Awesome!! 🎉🎉🎉
PS: how many times have you said "client component"? 😂
I have one question....can you explain the purpose of wrapping a server component with a context provider? Can the context share data to the server component or its just to allow server components to be redered as server? And thank you for this tutorial, it helped me a lot!
Intrusive thoughts: Take a shot every time "component" is being said
My brother in Christ are you trying to die?
Thank you! Really useful information.👍

if i have product card component that contains the favorite button, should i direct make productCard component 'use client' or create a 'use client' favorite button component and import it in productCard
thank you
@52:40 did you ever get round to making this video? couldn't see it but would be v interested if you ever do!
Guess not :D
I find the "use clients" and "use server" weird, NextJS v12 made so much sense, since v13 not so much! Thanks for your videos!!!
There is no way out of dynamic rendering if we need the header component in use on the page right?
thanks man, keep posting videos like this
Thank you, Wesley, you resolved many of my issues.👍
Very good explaination as always! Could you please give me the VS code theme that you use?
