Shadcn Code Demo Block One
The local CodeBlockIllustration is the important source here. It is a client component that stores the active snippet in React state, animates the active tab indicator with motion.span, and renders syntax-highlighted examples through a local CodeBlock component using Shiki languages.
Use this code demo when a product page needs to show implementation detail without becoming raw documentation. The source is a React client component with Tailwind CSS panel styling, and the syntax work is delegated to the local CodeBlock component.
The snippets are placeholders that post to https://api.example.com/data or render a sample login page. Replace them with real SDK calls, CLI usage, or framework examples before shipping the shadcn UI blocks article or page.
What to customize
- Replace placeholder snippets with working product code.
- Keep the language tabs aligned with what your audience actually uses.
- Check the panel height and masks after adding longer code.
Implementation notes
Is this only a screenshot?
No. The source renders interactive tabs and syntax-highlighted code inside the demo panel.
Where should this appear?
Use it near developer-focused product copy, docs CTAs, or a section explaining integration in a Next.js app.
