What do you rebuild every time in a new Next.js App Router app? (alpha blocks installer)

Quick question for App Router folks: when you create a fresh Next.js app, what do you end up rebuilding every time (UI sections, auth, forms, admin CRUD, etc.)?

I’ve been prototyping a small alpha CLI called nextworks that copy-installs reusable Next.js “blocks” (shadcn-style) into a project. I’m sharing it here mainly to learn what’s worth building next, and to get rough-edge feedback on the Blocks kit (UI primitives + sections + templates).

If you’re willing to take a look or try it, that’s great — but no need to install anything to answer the question.

I’m primarily looking for:

  1. what you rebuild most often, and

  2. any “this would scare me / this feels unsafe” feedback on the install approach/docs.

Negative feedback is welcome, especially anything that feels unsafe/confusing in an alpha installer. If something breaks, posting OS + Node + Next.js version + the command you ran + logs helps a lot.

Feedback threads (if you do try it):
