+# @lynx-js/motion
+
+A powerful animation library for Lynx, ported from [Motion for React (framer-motion)](https://motion.dev/). It brings declarative animations and gesture handling to the Lynx ecosystem.
+
+## Installation
+
+```bash
+npm install @lynx-js/motion
+```
+
+## Usage
+
+### Basic Animation
+
+Currently, `@lynx-js/motion` supports imperative animations using the `animate` function on the main thread.
+
+```tsx
+import { animate } from '@lynx-js/motion';
+import { useMainThreadRef, runOnMainThread, useEffect } from '@lynx-js/react';
+import type { MainThread } from '@lynx-js/types';
+
+export function MyComponent() {
+ const elementRef = useMainThreadRef(null);
+
+ useEffect(() => {
+ runOnMainThread(() => {
+ 'main thread';
+ if (elementRef.current) {
+ animate(
+ elementRef.current,
+ { opacity: 1, x: 100 },
+ { duration: 1 },
+ );
+ }
+ })();
+ }, []);
+
+ return (
+
+ );
+}
+```
+
+For more comprehensive examples, please refer to the [examples/motion](https://github.com/lynx-family/lynx-stack/tree/main/examples/motion) directory in this repository.
+
+## Motion Mini (`@lynx-js/motion/mini`)
+
+Motion Mini is a lightweight, **main-thread-optimized** version of the library. It provides a core subset of animation capabilities designed for high performance and low bundle size.
+
+To use it, import from `@lynx-js/motion/mini`:
+
+```tsx
+import { animate, createMotionValue } from '@lynx-js/motion/mini';
+```
+
+### Key Features
+
+- **Main Thread Animation**: Runs directly on the main thread, bypassing the JS thread for smoother performance.
+- **Small Bundle Size**: Includes only essential animation logic.
+- **Optimized for Numbers**: Primarily designed for animating numeric values.
+
+### Differences from Standard Motion
+
+| Feature | Standard Motion | Motion Mini |
+| :-------------------- | :------------------------------------------------ | :------------------------ |
+| **Animation Targets** | Numbers, Strings (colors, units), Objects, Arrays | **Numbers only** (mostly) |
+| **Keyframes** | Full support | Limited support |
+| **Layout Animations** | Supported | Not supported |
+| **Gesture Handlers** | Full suite (drag, pan, hover, etc.) | Not included |
+
+> **Note**: `MotionValue` in Mini primarily works with numbers.
+
+### CLI Reference for Mini
+
+#### `createMotionValue(initial: T)`
+
+Creates a `MotionValue` that tracks state and velocity.
+
+```typescript
+const mv = createMotionValue(0);
+mv.set(100);
+```
+
+#### `animate(value, target, options)`
+
+Animates a `MotionValue` or number.
+
+```typescript
+animate(mv, 100, {
+ type: 'spring',
+ stiffness: 300,
+ damping: 30,
+});
+```
