Next.js + React Course: reactsimplified.com/?...
The app directory massively overhauled and improved routing in Next.js by adding tons of new advanced features. One of those features is parallel routes which make working with complex UIs that contain many unique elements much easier. In this video I will break down everything you need to know about this concept and also talk about what this concept can do for you.

The main benefit of this is being able to use the loading and error pages within each parallel route i am guessing. For most cases its fine to just import the server components, you hust have to remember to put your own suspense/error boundaries around them

@chrtravels 2 ай бұрын

I was wondering why this would be necessary when you could just import server components. This makes sense though. I could see the benefit of having the separate loading and error pages. I am not very familiar with using suspense/error boundaries, so that is something I need to delve into.

@tom.watkins 2 ай бұрын

@@chrtravels loading and error pages are just a nice abstraction over having to put in your own suspense and error boundaries so it's a nice DX improvement for people less comfortable using them. That being said, it's worth knowing how to use them yourself as Suspense in particular is usefulfor other things in react, things like lazy imports and the new 'use' hook with promises as props both work very nicely with Suspense

Hey Kyle, I'm curious if there's a method to eliminate the loading time experienced when navigating between pages in NextJS. I'm aiming to develop a Progressive Web App, but I've noticed that NextJS fetches each page from the server based on the URL, leading to some delay. This contrasts with React Router, where page transitions are nearly instantaneous since it doesn't require fetching the new page for every navigation. Is there a workaround or solution for this in NextJS? I almost think NextJS sucks for PWA.

@vivekkaushik9508 4 ай бұрын

PWA and SSR doesn't make sense. In order for an app to be PWA you've to make the app CSR so that client can download the entire app and run it offline

@movoyemickele 4 ай бұрын

@@vivekkaushik9508 Do you have any insights on implementing this in NextJS? Simply specifying 'use client' doesn't work, as the app's router is designed to deliver individual pages for each specified URL. I'm looking to enable the user to download the entire app, similar to the experience with plain React where the user downloads the entire app. Any suggestions?

The docs aren't clear but it sounds like the parallel route has to be a server component. I have a PostList server component, that I could turn into a parallel route, however I have a PostCard, which is imported into the PostList. The PostCart is a client component. So I would not be able to use the Parallel routing on the cards themselves? It's the cards that I would want to have the loading state on.
