Measured entry

shadcn-card

cardunclassified

A composable React card primitive with header, title, description, action, content, and footer slots. It ships as copied TypeScript source rather than a package, and relies on React, a local cn class-merging helper, Tailwind-style utilities, and configured card color tokens.

Verdict

A sensible low-level card for an existing shadcn-style codebase. It builds and mounts in the prepared harness, but the bare project cannot resolve its local utility import, so it needs a shadcn-style setup before it is usable.

Use it if

  • Your app already follows shadcn conventions and needs a consistent container primitive.
  • You want separate structural slots that remain easy to reorder, omit, or style.
  • You need a neutral card base for dashboards, settings, pricing, or summary content.

Skip it if

  • You need a standalone component that works without local utility and theme setup.
  • You require semantic heading elements by default, since the title slot renders a div.
  • You want a card with built-in interaction, selection, loading, or disclosure behavior.

In a non-shadcn project, add the cn helper and its import alias, configure a Tailwind-compatible utility pipeline, define the card and muted theme tokens, and ensure the container-query and data-attribute variants used by the classes are supported.
