Measured entry

kibo-dropzone

inputminimal-flat

A client-side React dropzone shipped as copied shadcn registry source. It wraps react-dropzone in a full-width shadcn Button, adds Lucide upload feedback, and exposes context-based content and empty-state helpers. It depends on react-dropzone, lucide-react, the shadcn Button and cn utility, plus the project’s Tailwind theme classes.

Verdict

A useful composable starting point for shadcn applications, but not ready to ship unchanged because its clickable Button contains the file input and triggers a serious nested-interactive finding. The bare mount fails, so it needs a shadcn-style setup and an accessibility markup pass.

Use it if

  • You already use shadcn conventions and want a file picker with drag, click, validation, and disabled-state behavior.
  • You want composable selected-file and empty-state content while keeping upload transport in your own application code.
  • You are prepared to correct the nested control markup before treating the component as accessibility-ready.

Skip it if

  • You need an uploader that handles network requests, progress, retries, previews, or file removal out of the box.
  • You require clean accessibility checks without modifying the root Button and nested file input structure.
  • Your project does not use Tailwind and you do not want to recreate shadcn theme utilities and component primitives.

In a non-shadcn project, add react-dropzone and lucide-react, provide a compatible Button and cn helper, configure the @ path alias, and recreate the Tailwind utilities and theme tokens used by the source. Replace the nested interactive structure with an accessible drop target before release.
