Am I missing something? The entire point of next.js is that it's backend+frontend in one project
nextjs dx is a special kind of hell. disclaimer: im just a simple rails guy.
It's yet another backend framework, added that it only runs on vercel infrastructure.
There are better front end and back end servers, those that simply rely on nodejs to serve. Next.js does that, without vercel.
I'd say we disagree on the simplicity then: hydration, nextjs API reinventions of every interaction else 'use client' as an escape hatch which means it runs on the client but then what does the non 'use client' code do if nextjs is not a client-facing framework?
