Your thumbnail it's the american war poster, hilarious

[@mattgic42]

I just wanted to take the time to show appreciation and say thank you for everything you do for us with your videos, sharing your knowledge and helping people like me to grow in the process. You're greatly appreciated.

[@pim8268]

Wow, the quality of this channel is just wonderful. The timing of the explanations seams flawless to me too, not too fast, not too slow, just right. Thank you, Jack, for sharing your knowledge like this!

[@demiann4160]

Started following you since your tRPC video. Like your style that explains so much in only a couple of minutes. Might be worth mentioning that the first revalidation technique (time-based) shown here is what next.js calls ISR, Incremental Static Regeneration. Congrats on all your amazing content!

[@Delba]

Awesome video Jack! I like how you built on and explained each method 🤩

[@netharian_]

Jack, you’re my favorite instructor right now. Every single video is very interesting and so well explained. Also, you bring examples with pokemon, which makes it even better hahaha.

[@Bliqu1]

Thank you very much for the straightforward and clear explanations. You've fitted in 30 minutes everything that's really needed. Wish you and your channel all the best!

[@mithatercan]

I had been struggling to understand the differences between these 3 terms then I came across your channel and this video. I just want to appreciate you. Thanks a lot for this awesome explanation, everything is super clean now. ✌🙏

[@kevinzunigacuellar]

amazing video Jack, literally summarized data fetching in 30 minutes

[@theepan27]

This is a must watch video for anyone to understand about CSR, SSR and SSG's. No lags and very crisp with a nice and easy example. You have got a happy subscriber

[@mohamedsafwat6696]

I've been struggling with this for a few days and I can confidently say this is the best explanation of all time, thank you man

[@kentay4460]

Just started to work on SEO migrating my React App to a Next App, that's the best explanation I've seen through my researches as I started from zero on SSG and SSR. Thanks a lot !

[@jonathanvandenberg3571]

That room-flip-transition at the end was freaking mucho mega awesome!

[@vladandreit]

You could create videos 3 hours long and i would watch every second. I was waiting for a good video explanation for SSG on demand. Now i have good understanding for all methods. Thank you! Keep up the good work.

[@jwickerszh]

Small clarification at the end: You do need to "run a server" when using revalidation (aka ISR) as this does SSR (and you obviously have a server API route to call for forced revalidation). However it is still very cool as the SSG content is still there if the server or DB crashed. Could have spent a few minutes on mixing the methods, eg: * in SSG what happens if you added a new pokemon id, would the route do SSR on the first hit. * on the list page you could use SSG for a limited list of pokemons like the first 20 instead of generating it for the whole 800+, then use CSR to fetch on scroll for example

[@aqua123670]

ok Mr. Expert then please make the video

[@centereddev]

Not sure why you got that rude response, these are good points.

[@alexr3d]

I was trying to do this a few hours before you published. Best explanation on KZbin. Congrats.

[@zombiefacesupreme]

WOW!! What a great video! I'm just learning, and I knew every term, but this hammered in the concepts so well. I'm really glad I subscribed to you and decided to check out some older videos!

[@mcylinder]

This was mucho crazy awesome! Clear, concise, pertinent. Best I've seen. Glad to subscribe.

[@t0mmx]

Mucho awesome explanation! I already knew most of it from before, but it was a great recap with a sprinkle of new info such as revalidate!

[@SpaghettiRealm]

I'm senior web developer but new to NextJS, and this video explains those concepts in the best way I can find. Also, all your content is just on the point! Thank you Jack 💙

[@dariuspranskus]

Thank you for the great demonstration of Client, SSR and SSG features. I also liked the terminal prompt customisation.

[@universecode1101]

This is huge Jack 🤯Thanks for the explanations, as always amazing

[@clausstilborg8330]

I absolutely love you content Mr Herrington

[@axe-z8316]

geeeezus was just looking at that ! great content man, keep it up with the extended jsx world.

[@duketip2010]

How are you only at 61k subs? Your videos are fantastic and you explain things perfectly!

[@DavidCCR]

Jack every video is getting better. Love it! "CLEAN ARCHITECTURE" is a nice and interesting topic for sure those days. I would like to see some videos about it. Thank you so much!

[@davidkezi6086]

Thanks again Jack, absolutely love this video. This has to be the best explanation and comparison i have seen of SSR and SSG.

[@seymurmammadov3868]

you’re an amazing teacher so happy I stumbled on your channel

[@BetulKaplan]

This was the neatest explanation I have had for SSR - CSR. Thanks a lot!

[@jonatanmark7557]

Really cool next.js tutorial.... 👍👍👍After watching this video, I could understand easily about the CSR, SSR and SSG. Thanks Jack!

[@SunilSkanda]

Fantastic explanation of all the different rendering methods available in Next.js. 🔥

[@TheOlian04]

Ohh.. The production quality has really gone up recently! Well done!

[@usmanmughal5916]

I already knew the rendering method but, after watching this I wished it was there before. Video was refreshing and it is the best short introduction with perfect example.

[@vasiovasio]

It's a real showcase of how flexible is Next.js! Really useful video! Thank you, Jack!

[@lucaszanek6204]

Awesome!!! Finally i really understood the core differences and where use one of each, thanks for this video!

[@simonedwards7101]

I love it when it goes wrong! As i'm learning I like to take the content I watch and apply it to something I'm working on (I'm not a web dev by trade). What was wrong: One of the entries in my json had an incorrectly ordered key/value pair! This caused some lovely misleading errors that took me a while to pin down. Funny thing is on the surface it looked like it was running in dev but come build time it would error out. Turns out in dev it was only partially working with the second part of the list having slugs and posts that didn't match. Basically everything after the "typo" was broken but only in as much as the slug and post didn't match! Actually, it was a random console.log that caught my eye in as much as it had an empty array at the end of the returned json response. So again, everything looked ok until the last entry in the return. All good fun. Thanks Jack, content like this keeps me inspired and motivated to push through the issues I experience as a learner.

[@pratikbankar4757]

You are awesome Jack. Thank you for keeping up with such a wonderful content always.

[@ayush612]

PROS: Course Quality Brilliant Explanation Beautiful Animations CONS:

[@SuperPompey77]

Very good explanation on the different methods of rendering pages.

[@subhadeepchowdhury5244]

Tomorrow, I have an interview for Next .js developer position. This video is really helpful to understand the core concepts of Next 12.

[@raqibnur]

This was the easier explanation I have seen ever. now SSR and SSG are fully clear to me. special thanks for force revalidating

[@vincentsolon3216]

Wow thank you so much! I have a task to build an ecommerce site and your tutorial help me a lot to understand

[@dantownsend0]

Amazing video - one of the best programming tutorials I've seen.

[@maysamtayyeb4552]

Jack, I never regret watching your rich content. You explain it the way I need to learn stuff. Thank you so much

[@krishgarg2806]

Great! By the way, you can use the "Rest Client" extension so you don't have to write raw curl requests but also keeping it minimal by design.

[@venicebeachsurfer]

You mean something like postman or insomnia?

[@codernerd7076]

Next.js, gotta server render 'em all, it's you and me I know it's our destiny Next.js, oh, you're my best friend In a React.js world we must defend!

[@TheLastNinja]

A great way to demonstrate the server side rendered step is the preview of the first request in the network tab (change filter to all)

[@Billy_98]

Thank you so you much, Jack! Greetings from Romania!

[@MrBox4soumendu]

Thank you very much. This is the best one to understand the use cases. Thanks a lot!!!

[@atosupriyanto6990]

My understanding is clear when landed to this video, thanks!

[@bythealphabet]

😂, Jack when you said "that to changed the code for SSG was going to take a lot of work, I paused the video and went to do some arrents. You got me😅 so funny!

[@shubhamlatiyan7972]

Very detailed and awesome video, thank you Jack

[@MrKeliv]

Awesome tutorial and explanation about SSR and SSG. Thanks

[@sean_dev]

Awesome explanation and showcase, thank you!

[@shesharaopuli8887]

Simply the best video of Next.Js rendering methods 💕

[@al-doori2392]

Just waw, thank you so much, may god bless you and your family, you really reminding me of my dad. Appreciate everything you post.

[@sergnio]

What!!! Wow what a fantastic overview and especially demonstration of NextJS. Easy subscribe for me!! Couple questions: 1. What do you mean by "I would use SSR for search if things are dynamic", woudln't you use CSR (client side rendering) for this since there are many unknowns? 2. If you have an app that's mostly static with videos / audio, with a few dynamic elements like user accounts, user preferences, etc. this feels like a strong case for SSG, but I would love to hear your perspective. Something like a personal website that has tutorials of some sort where you upload videos / courses maybe once a month (I honestly don't have one, but it's a simple example)

[@edouardsouan6330]
