I'm really curious too, the only codebase I've seen that was like their description with react treated different pages/routes as one massive separate component.
Not exactly utilizing the benefit of JSX but it's a pattern you might blindly fall into if you only came from a templating background.
I can't, our app is enterprise SaaS built as SPA. Nextjs is imho garbage. The only reason I can imagine it is so popular is that average React devs are indeed very bad with code organization. If I needed server rendering I would go with Astro + interactive islands.
I see, you're talking about a fully client-rendered SPA. I guess you can always count on your users running modern PCs, with fast internet and no SEO needs. Things aren't that nice in the outside world lol.
