shadcn-ui/taxonomy
An open source application built using the new router, server components and everything new in Next.js 13.
A Next.js 13 App Router reference app by the shadcn guy, showing auth, subscriptions, MDX docs, and a rich-text editor wired together. Now officially archived. Useful as a historical example of early App Router patterns, not as a starting point for new projects.
The route group structure (auth), (dashboard), (editor), (marketing) is still a clean pattern worth studying. Full stack in one repo: NextAuth, Prisma, Stripe webhooks, OG image generation, MDX via Contentlayer — you can see how they interact without reading docs in five different places. shadcn built his UI component library off this, so the components/ui directory is the direct ancestor of shadcn/ui.
Archived and explicitly flagged as not reflecting current best practices — the App Router has changed enough since Next.js 13 preview that several patterns here will mislead you. PlanetScale shut down their free tier, so the DB setup needs replacing before you can run it. Contentlayer is also abandonware now, so the MDX pipeline has two dead dependencies. No tests of any kind.
