Moving Railway's Frontend Off Next.js

We migrated

Railway Blog
I have a Nextjs heavy app which takes around 7 minutes currently. But I've been thinking of moving away from next for a long time now. TanStack seems to be a good fit. This gives me a bit more confidence in just doing it.

I've been pretty happy with TanStack start for a medium-sized project. I would not know how its build time would compare to Next, but our similarly sized Remix (sorry, React router v7) app takes longer to build.

TanStack just has a nicer mental model overall and works great with TanStack query for cache I validation and stuff like that.

Remix was promising but there was so much ceremony in registering API routes and stuff. Tanstack just lets you define server functions arbitrarily with no ceremony.

Might be worth a spike and some tokens to ask Claude Code to migrate and test the build time and ergonomics.
