Installation#

bash

npx shadcn@latest add @minidev/thinking-block

MiniDev UI is in the shadcn registry directory, so the short form works with no setup. Older CLI versions can use the full URL: npx shadcn@latest add https://ui.minidev.pro/r/thinking-block.json

Usage#

tsx

import { ThinkingBlock } from "@/components/ui/thinking-block"

export function Example() {
  return (
    <ThinkingBlock>Considering Hairline tokens, violet accent, and reduced motion…</ThinkingBlock>
  )
}
