Code Skeleton

A loading skeleton for code: the bars repeat the shape of a listing — nesting indents, an empty line and a short closing brace.

React + Tailwind, shadcn-compatible: press “Copy for AI” and your Cursor or Claude Code agent installs it with the shadcn CLI.

What you can change

  • the number of rows through rows
  • the screen reader caption through label
  • the shape table in the constant inside the file

A link for your AI agent: preview, code and instructions.

FAQ

How do I add Code Skeleton with Cursor or Claude Code?
Press “Copy for AI” on this page and paste it into your agent's chat. The instruction contains the shadcn CLI install command, the dependencies and what to keep, so the agent installs this exact component instead of recreating a lookalike.
What does Code Skeleton depend on?
No npm packages beyond React and Tailwind CSS.
What can I change in Code Skeleton?
Adapt: the number of rows through rows; the screen reader caption through label; the shape table in the constant inside the file. Keep as installed: the local --vibeui-codeblock-014-* palette — do not swap it for your theme tokens; the deterministic width table: Math.random drifts between server and client and breaks hydration; the listing shape — indents and the empty line: even identical bars read as a paragraph, not as code.
Is Code Skeleton free?
Yes. The preview is open without an account; with a free account you can copy up to 20 components a month.

For developers

npx shadcn@latest add https://vibeui.club/r/pro/codeblock-014.json

This command needs a signed link: sign in and open “Component source” below — it issues a working link valid for 30 minutes. All install options

Technical notes

The component is self-contained: one file, zero dependencies, its own palette in the local --vibeui-codeblock-014-* variables. Server component: no hooks. The row widths and indents are taken from a constant shape table and repeated in a cycle — random values would diverge between server and client and break hydration. The shine runs along background-position rather than transform, so no extra layer is needed; the row height is set by a variable and matches the line spacing of a real listing. The root has role=status and aria-busy, and the caption is visually hidden but available to a screen reader.
