Measured entry

shadcn-checkbox

checkboxunclassified

A client-side React checkbox delivered as a shadcn registry TypeScript component. It wraps the Radix checkbox primitive, renders a Lucide check icon, and styles state, focus, disabled, invalid, and dark-mode behavior with Tailwind utilities, theme tokens, and the shared cn helper.

Verdict

A solid fit inside an existing shadcn codebase: the wrapper is small, editable, and delegates interaction behavior to Radix. It is not drop-in for a bare React app and needs a shadcn-style setup before it will build and mount.

Use it if

  • You already use shadcn conventions and want a checkbox that fits the same theme tokens.
  • You need Radix-managed checked state, keyboard behavior, and form semantics behind a compact styled control.
  • You want the component source in your project so its states and styling remain directly editable.

Skip it if

  • Your project does not use Tailwind utilities or shadcn theme tokens and you do not want to recreate that styling layer.
  • You want a self-contained package component with no local utility alias or copied source file.
  • You already standardize on another checkbox primitive or icon library and want to avoid parallel dependencies.

Providerno provider required in the harness

In a non-shadcn project, add Radix UI and Lucide React, provide the cn class-merging helper at the expected import alias, and configure Tailwind with the referenced color tokens, state variants, radius, shadows, focus styles, and dark-mode rules. Keep it as a client component where that distinction applies.
