Skeleton

import { Skeleton } from "@/components/ui/skeleton"

export default function SkeletonDemo() {
  return (
    <div className="flex items-center space-x-4">
      <Skeleton className="size-12 rounded-full" />
      <div className="space-y-2">
        <Skeleton className="h-4 w-[250px]" />
        <Skeleton className="h-4 w-[200px]" />
      </div>
    </div>

Installation

npx logic2b@next add skeleton

Working with an AI assistant? Copy this prompt into Claude Code, Cursor or Copilot — it carries the install steps, a no-CLI fallback and a verification checklist.

Add the "skeleton" item from the logic2b ui registry (https://ui.logic2b.com) to this project. Follow every step and verify at the end.

## Steps

1. If the project has no `components.json` yet, set up logic2b ui first:

   ```bash
   npx logic2b@next init
   ```

2. Install the item (the CLI resolves registry dependencies automatically):

   ```bash
   npx logic2b@next add skeleton
   ```

3. Install any npm dependencies the command prints.

## If the CLI is not available

Do it manually from the registry payload:

1. Fetch https://ui.logic2b.com/r/skeleton.json.
2. Write every entry in `files[]` to its mapped project path (see below).
3. Repeat (recursively) for each name in `registryDependencies`.
4. Install every package listed in `dependencies` across those payloads.

## Registry reference

- Index of every item: https://ui.logic2b.com/r/index.json
- Item payload (full source): https://ui.logic2b.com/r/<name>.json
- Usage examples per item: https://ui.logic2b.com/r/demos/index.json → https://ui.logic2b.com/r/demos/<demo>.json
- Docs index for agents: https://ui.logic2b.com/llms.txt (full docs: https://ui.logic2b.com/llms-full.txt)
- Every docs page is Markdown when you append `.md` to its URL.

Registry file paths map to project paths like this:
- `ui/*` → `@/components/ui/*`
- `blocks/<name>/*` → `@/components/*`
- `charts/*` → `@/components/charts/*`
- `hooks/*` → `@/hooks/*`
- `lib/utils.ts` → `@/lib/utils.ts`
- `theme.css` → next to the project's Tailwind entry stylesheet

## Conventions (do not break these)

- Tailwind CSS v4 (CSS-first config; no tailwind.config.js needed) and React 19.
- All colors go through semantic tokens (`bg-primary`, `text-muted-foreground`,
  `border-border`, …). Never hardcode hex/oklch values in components.
- Dark mode is class-based: toggle `.dark` on `<html>`.
- Icons come from lucide-react.

## Verify before finishing

1. The dev server starts and the app renders without console errors.
2. TypeScript compiles (`tsc --noEmit` or the framework's check).
3. Components use the theme: a `<Button>` shows the primary token color,
   and toggling `.dark` on `<html>` switches the palette.

Copy into ui/skeleton.tsx:

import * as React from "react"

import { cn } from "@/lib/utils"

function Skeleton({ className, ...props }: React.ComponentProps<"div">) {
  return (
    <div
      aria-hidden="true"
      data-slot="skeleton"
      className={cn("bg-accent animate-pulse rounded-md", className)}
      {...props}
    />
  )
}

export { Skeleton }

Usage

import { Skeleton } from "@/components/ui/skeleton"

<Skeleton className="h-4 w-[250px]" />

Usage notes

Skeleton renders a single <div> and forwards every native <div> prop. Set its shape and size with className.

Examples

Card

import { Skeleton } from "@/components/ui/skeleton"

export default function SkeletonCardDemo() {
  return (
    <div className="flex flex-col gap-3">
      <Skeleton className="h-40 w-[300px] rounded-xl" />
      <div className="space-y-2">
        <Skeleton className="h-4 w-[300px]" />
        <Skeleton className="h-4 w-[220px]" />
      </div>
    </div>
  )
}

List

import { Skeleton } from "@/components/ui/skeleton"

export default function SkeletonListDemo() {
  return (
    <div className="flex w-[320px] flex-col gap-4">
      {Array.from({ length: 3 }).map((_, i) => (
        <div key={i} className="flex items-center gap-4">
          <Skeleton className="size-10 rounded-full" />
          <div className="flex flex-1 flex-col gap-2">
            <Skeleton className="h-3.5 w-full" />
            <Skeleton className="h-3.5 w-2/3" />
          </div>
        </div>
      ))}
    </div>
  )
}

Live playground

Edit the component props and inspect the exact JSX before copying it. The preview loads only when this section enters the viewport.

Generated JSX

API reference

Generated from the public TypeScript exports in src/ui/skeleton.tsx.

View JSON

Component

Props: React.ComponentProps<"div">

Accessibility contract

Machine-readable behavior and consumer responsibilities for skeleton.

View JSON

Support: Composition contract
Pattern: loading placeholder; HTML div

Built-in semantics

Is hidden from assistive technology by default and does not announce loading on its own.

Consumer responsibilities

Put the containing region in an appropriate busy/status state and preserve a stable accessible name while content loads.

Known limitations

• A standalone skeleton has no semantic loading announcement.
