Measured entry

shadcn-block-sidebar-01

sidebarminimal-flat

A documentation-style sidebar block shipped as copied React and TypeScript source through the shadcn registry. It includes grouped navigation, search, a version dropdown, breadcrumbs, a collapsible rail, and a content shell. It depends on the shadcn sidebar and supporting primitives, Tailwind theme conventions, Radix UI, class-variance-authority, and Lucide icons.

Verdict

A credible starting shell for docs and admin layouts, with clean responsive behavior and no runtime failure in the configured harness. It needs a shadcn-style setup and an accessibility pass to remove the duplicate, nested main landmark before production use.

Use it if

  • You need a documentation or settings shell with grouped, persistent navigation.
  • Your app already uses shadcn primitives, Tailwind theme tokens, and path aliases.
  • You want responsive sidebar behavior with a compact mobile trigger and collapsible rail.

Skip it if

  • You need a drop-in package for a plain React project with no shadcn infrastructure.
  • Your page already defines its main landmark and you cannot adjust the block's content shell to avoid duplicate or nested main landmarks.
  • You want application-specific navigation logic rather than replacing static sample links and version data.

Providerno provider required in the harness

For a non-shadcn project, add Tailwind and the shadcn theme variables, configure the at-sign source alias, provide the shared class-name utility, copy the sidebar, breadcrumb, separator, label, and dropdown-menu primitives, and install Radix UI, class-variance-authority, and Lucide React. Reconcile the block's main landmark with the host layout.
