shadcn/ui blocks

Use it for: the default app scaffolding — dashboard layout, sidebar shells, auth pages, and charts. They're built only from stock shadcn components and tokens, so they look right under every design system with zero adaptation. This is the first place to look for app screens; reach for Aceternity/Magic UI only for marketing pages. (Stock shadcn components — button, dialog, form… — are not catalogued; use npx shadcn@latest add <component> directly.)

Install

# default registry — no namespace or config needed; the style comes from components.json
npx shadcn@latest add dashboard-01
npx shadcn@latest add sidebar-07 login-03 chart-area-interactive

Gotchas

• Blocks write routes. dashboard-01 and every sidebar-NN write app/dashboard/page.tsx; login/signup write app/login/page.tsx / app/signup/page.tsx — Next.js App Router assumed. Move them if your routes differ.
• Shared filenames. Most sidebar blocks (and dashboard-01) write components/app-sidebar.tsx, nav-main.tsx, nav-user.tsx… Installing a second sidebar block overwrites the first — pick one shell.
• dashboard-01 pulls @tabler/icons-react, dnd-kit, @tanstack/react-table, zod and ~19 shadcn components, plus a data.json fixture.
• Login/signup blocks import cn from the new cn npm package (shadcn-ui/cn) rather than @/lib/utils.
• Charts read --chart-1…5; every design system here defines them. Check contrast of the chart palette in dark mode.
• Only the new-york-v4 style has charts; the base-nova (Base UI) style currently ships dashboard/sidebar/login/signup but no chart blocks.
