🦴 react-auto-skeleton-z

---

Automatic skeleton UI generation for React components.
Plugin-first, component-driven, layout-aware skeletons — no wrapper required.

Live Example

---

✨ Features

• Auto-generate skeletons from real components
• Component-driven (Component.skeleton) or plugin-driven
• Layout-aware → zero layout shift
• Async / lazy component support
• Works with any UI library (Antd / MUI / custom)
• Hook API: useAutoSkeleton

---

📦 Installation

npm install react-auto-skeleton-z
# or
yarn add react-auto-skeleton-z

• Import global CSS for animation:

import "react-auto-skeleton-z/styles.css"

🚀 Examples

1️⃣ Basic usage (component .skeleton property)

import React from "react"
import ReactDOM from "react-dom"
import { AutoSkeleton, SkeletonCircle, SkeletonText, SkeletonRect } from "react-auto-skeleton-z"
import "react-auto-skeleton-z/styles.css"

// Real component
function UserCard({ user }) {
  return (
    <div style={{ width: 300, padding: 16, border: "1px solid #ccc", borderRadius: 8 }}>
      <img src={user.avatar} style={{ width: 64, height: 64, borderRadius: "50%" }} />
      <h3>{user.name}</h3>
      <p>{user.email}</p>
      <button>Follow</button>
    </div>
  )
}

// Define skeleton directly on component
UserCard.skeleton = () => (
  <div style={{ width: 300, padding: 16, border: "1px solid #ccc", borderRadius: 8 }}>
    <SkeletonCircle style={{ width: 64, height: 64 }} />
    <SkeletonText />
    <SkeletonText />
    <SkeletonRect style={{ width: "100%", height: 32, marginTop: 8 }} />
  </div>
)

const fakeUser = { avatar: "https://i.pravatar.cc/64", name: "John Doe", email: "john@example.com" }

function App({ loading }) {
  return (
    <AutoSkeleton loading={loading}>
      <UserCard user={fakeUser} />
    </AutoSkeleton>
  )
}

ReactDOM.render(<App loading={true} />, document.getElementById("root"))

✅ Skeleton appears automatically when loading=true
✅ Real UI renders when loading=false

// Profile.tsx => Next example
import React from "react"
import { SkeletonCircle, SkeletonText } from "react-auto-skeleton-z"

export default function Profile({ user }) {
  return (
    <div>
      <img src={user.avatar} />
      <h3>{user.name}</h3>
    </div>
  )
}

// Add skeleton for AutoSkeleton
Profile.skeleton = () => (
  <div>
    <SkeletonCircle />
    <SkeletonText />
  </div>
)


// lazy profile
const LazyProfile = lazy(() => import("./Profile"))

---

2️⃣ Plugin system

import { createSkeletonPlugin, AutoSkeleton } from "react-auto-skeleton-z"

const ProfilePlugin = createSkeletonPlugin({
  name: "profile",
  rules: [
    {
      match: (el) => el.type?.name === "Profile", 
      skeleton: "circle"
    }
  ],
})

<AutoSkeleton loading plugins={[ProfilePlugin]}>
  <Suspense fallback={<div>Loading...</div>}>
    <LazyProfile />
  </Suspense>
</AutoSkeleton>

• Plugin allows automatic detection without defining .skeleton for every component.

---

3️⃣ useAutoSkeleton hook

import React, { lazy, Suspense } from "react"
import { useAutoSkeleton } from "react-auto-skeleton-z"

const LazyProfile = lazy(() => import("./Profile"))

function Page({ loading }) {
  const content = useAutoSkeleton(
    <Suspense fallback={<div>Loading...</div>}>
      <LazyProfile />
    </Suspense>,
    { loading }
  )

  return <>{content}</>
}

export default Page

• Returns a tree with skeletons automatically injected.

---

4️⃣ Async / Lazy components

import React, { lazy, Suspense } from "react"
import { AutoSkeleton } from "react-auto-skeleton-z"

const LazyProfile = lazy(() => import("./Profile"))

<AutoSkeleton loading>
  <Suspense fallback={<div>Loading...</div>}>
    <LazyProfile />
  </Suspense>
</AutoSkeleton>

• Lazy components automatically show skeleton until loaded.

---

5️⃣ Custom rules (layout-aware)

<AutoSkeleton
  loading
  rules={[
    {
      match: (el) => el.props?.style?.borderRadius === "50%",
      skeleton: "circle",
    },
    {
      match: (el) => el.type === "button",
      skeleton: "rect",
    },
  ]}
>
  <UserCard />
</AutoSkeleton>

• Rules let you match elements dynamically based on props, type, or other heuristics.

---

🧠 Why use react-auto-skeleton-z?

• Zero manual wiring
• Layout-aware → no layout shift
• Component-driven → easy maintenance
• Plugin-friendly → reusable rules
• Perfect for dashboards, lists, cards, or heavy-loading UIs
