Measured entry

kibo-image-crop

imageminimal-flatdo not use

A shadcn registry component for composing an image crop area with optional apply and reset controls. It reads a File in the browser and returns a cropped PNG data URL through canvas, using react-image-crop, Lucide icons, Radix Slot, Tailwind utilities, a cn helper, and a shadcn Button.

This entry is a do-not-use verdict

It is published because it broke, not in spite of it. The run stopped at the production build, and the recorded output is printed further down this page.

Verdict

Useful primitives for a shadcn app, but this publication fails because its Button import points at the author's private repository alias. It needs a shadcn-style setup and source edits before it can build, and the ineffective output-size retry deserves correction before production use.

Use it if

  • You want browser-side cropping from a File and can accept a PNG data URL as the result.
  • You need composable crop content, apply, and reset controls rather than a fixed dialog or upload flow.
  • Your app already follows shadcn conventions and you are willing to replace the source repository's Button import.

Skip it if

  • You need a drop-in component that builds outside the author's monorepo without import changes.
  • You require dependable output-size enforcement, because the oversized-image retry does not actually reduce the canvas dimensions.
  • You need server-side cropping, preserved image metadata, or an uploaded file rather than a browser-generated data URL.
  • You require verified runtime accessibility results, since the component did not build or mount in the harness.

Providerno provider required in the harness

For a non-shadcn project, install react-image-crop, lucide-react, and radix-ui; import the crop library stylesheet; provide equivalents for Button and cn; replace both repository aliases; and supply the Tailwind utilities and theme variables used by the markup. Keep it client-only because it relies on FileReader, image elements, and canvas.
