Measured entry
shadcn-block-sidebar-10
A Notion-like dashboard shell with a collapsible sidebar, team switcher, favorites, nested workspaces, breadcrumbs, and a page-action popover. It ships as a shadcn registry block split across a page and client components, and depends on the shadcn sidebar stack, Radix UI, class-variance-authority, and Lucide icons.

What the harness recorded
BARE BUILD
✗ Build failed in 26.03s error during build: [vite:load-fallback] Could not load <sandbox>/src/lib/utils (imported by src/components/ui/breadcrumb.tsx): ENOENT: no such file or directory, open '<sandbox>/src/lib/utils'
Verdict
A capable starting shell for shadcn-based workspace apps, but not production-ready as shipped because several icon controls lack accessible names and the markup has list and landmark problems. It needs a shadcn-style setup, followed by an accessibility pass and replacement of placeholder behavior.
Use it if
- You need a content-heavy workspace or knowledge-app shell with nested navigation.
- Your app already uses shadcn conventions and can replace the sample links and data with real routing.
- You want desktop and narrow-screen behavior packaged with menus, collapsible groups, and team switching.
Skip it if
- You need an accessible production component without first labeling icon-only controls and repairing list and landmark structure.
- Your project does not use Tailwind utilities, shadcn theme tokens, or path aliases and you want a drop-in component.
- You only need a small navigation rail and do not want the added menu, popover, breadcrumb, and icon dependencies.
Install
| Declared dependencies | radix-ui, class-variance-authority, lucide-react |
|---|---|
| Missing on install | none |
| Bare install | fails once the shadcn-style helpers are removed, so it needs that setup |
| Provider | no provider required in the harness |
In a non-shadcn project, add Tailwind and the expected theme variables, configure the at-sign path alias, provide the shared lib/utils class-merging helper, install Radix UI, class-variance-authority, and Lucide React, then bring in the sidebar, breadcrumb, separator, popover, collapsible, dropdown-menu, and button primitives. Add accessible labels and correct the list and main-landmark nesting before release.
