Measured entry

kokonut-file-upload

inputdark-futuristicmotion on file

A client-side drag-and-drop file picker with animated idle, dragging, progress, cancel, and error states. It ships as a shadcn registry TypeScript component, uses Tailwind utility classes and a local cn helper, and depends on React, Motion, and Lucide. Its built-in progress is simulated, so real transfer logic belongs in the success callback or a replacement handler.

What the harness recorded

BARE BUILD

Verdict

A credible, adaptable drop zone when the surrounding app owns the actual upload. It builds and mounts cleanly in the prepared harness, but it needs a shadcn-style setup and does not mount in a bare project as copied.

Use it if

  • You want a polished single-file drop zone with file type, size, and custom validation hooks.
  • Your app already uses Tailwind and shadcn-style aliases and can wire the selected file into its own upload service.
  • You need light and dark styling plus animated progress and error feedback in one component.

Skip it if

  • You need real network upload progress out of the box, because the included progress sequence is only a simulation.
  • You need multiple-file selection, queued uploads, retry controls, or resumable transfers.
  • You want a dependency-light native input and do not want Motion, Lucide, Tailwind utilities, or a local class-name helper.

Providerno provider required in the harness

In a non-shadcn project, add Tailwind with dark-mode support, install Motion and Lucide React, configure the at-sign path alias, and provide a cn class-merging utility under the local lib path. Keep it as a client component, then replace or bypass the simulated progress flow when connecting real storage.
