Measured entry

kokonut-switch-button

buttondark-futuristicmotion on file

A client-side light and dark theme toggle rendered as a styled button with a rotating sun icon, optional label, hover sheen, and size choices. It ships as a shadcn registry component and depends on React, next-themes, Lucide, Tailwind utility classes, the shadcn Button primitive, and the cn helper.

Verdict

A polished fit for an existing shadcn theme stack, with clean mounting and no detected accessibility or viewport issues. It needs a shadcn-style setup and is not drop-in for a bare React project. Check whether its current-theme label matches your product language.

Use it if

  • You already use next-themes and want a compact theme toggle with visible interaction feedback.
  • Your interface uses shadcn primitives and Tailwind styling, so the imported Button and utility classes fit directly.
  • You need labeled and icon-only variants across several control sizes.

Skip it if

  • Your app does not use next-themes or does not expose light and dark themes.
  • You need a framework-neutral control without shadcn aliases, Tailwind utilities, or a shared cn helper.
  • You want the control label to describe the theme that clicking will activate, since this implementation labels the current theme.
  • You need multiple visual variants, because the public variant prop currently offers only the minimal style.

Providerno provider required in the harness

In a non-shadcn project, add next-themes with its theme provider, Lucide React, Tailwind support for the component's utility classes, a compatible Button primitive, the cn class-merging helper, and aliases for the component and utility import paths. Preserve client-side rendering for theme access.
