NextJS is probably the best way to build your next React application. There are few better ways to do full stack with Javascript. Hopefully this video helps you better understand why!

I was the same man, then I tried it and found out that it is actually kind of a wrapper around your React application which lets you render portions of it on the server. It can seem as a lot when you read or hear about it, but when you actually start building with it following the docs, it all makes sense and it's not nearly as complicated as I thought before. Having a kind of solid understanding of React helps though, you can then easily differentiate Next from React parts.

Thanks for sharing, you have mentioned that when browser requests to next server, next will execute getServerSideProps and then react will use those props. However, we can use getStaticPaths function to serve all dynamic routes pre-rendered HTML in built time. In that case, when a user requests to next server, will next server execute some react or just sending the pre-rendered HTML in built time instead of runtime?

@sidwebworks9871 Жыл бұрын

I think the video title should be "How SSR/SSG works?". Also I would argue that a Next app is a multi-page application because the client still requests a new page when you visit a new route, it's just that the next router and hydration patterns makes it "feel like a SPA". It's not really a SPA. Anyways good video.

@rico454 Жыл бұрын

It is an SPA. _app only mounts once and handles all page routing so _app is the single page. NextJs just handles it quite cleverly making everything seem less. But you are right, the title of the video was confusing since I was expecting a deep dive into how the framework was built.

@sidwebworks9871 Жыл бұрын

@@rico454 What you said is true and yes I think the terms are usually juggled around. Although it looks like MDN defines a SPA as an application which loads a single document page and updates that document's body using javascript. You can look it up. AFAIK it's neither of those 2, it's a Hybrid react framework.

@sitter2207 Жыл бұрын

@@sidwebworks9871 Thats what i think of when I hear SPA as well. So I'm a bit confused still. If that's not how nextjs works, then its just a MPA, that becomes SPA after html is requested, why not just become a static page at this point ? Isn't being SPA the biggest selling point of... well single page applications ? Because it makes navigating through pages so much faster. But next loses that ability by requesting the server side rendered html at every route change. I feel so dumb for not understanding the point of nextjs but im also still a beginner

@rico454 Жыл бұрын

@@sidwebworks9871 Maybe I’m confused but doesn’t Next adhere to that criteria? _app is loaded once and everything else is loaded with javascript, whether it’s static or SSR? Well that’s how I assume it works, I might be wrong

@m0rt068 Жыл бұрын

I don't know what you mean but serious information or data should always come from a secured api. You shouldn't just hide sensitive information in your client side app but should also secure your backend. Always verify who the user is in your backend before you send that data to your frontend. Doesn't matter what you are using this shouldn't be problem.

I've been learnig NEXTjs for almost a week reading the Pages Router docs, and there's something that still doesn't make sense in my head.... When a page that was rendered on the server gets to the client as a Loading state or as an UI skeleton, does that mean that the server have a "correct" but empty HTML version of what the user gets after the client fetches and loads the data? Only then the user gets the 2nd correct but complete version of the same HTML page? Idk if that's clear enough, hopefully it is..
