Category: Development & Coding | Uploader: 199-biotechnologies | Downloads: 0 | Version: v1.0（Latest）

Creates 120fps GPU-accelerated animations with Motion.dev (Framer Motion successor) for React, Next.js, Svelte, and Astro projects. Use when user requests animation, motion, scroll effects, parallax, hero animations, gestures, drag interactions, spring physics, whileHover effects, whileInView animations, animated UI, micro-interactions, page transitions, or layout animations. Generates production TypeScript/JSX code with accessibility (prefers-reduced-motion) and performance validation (≥60fps). Supports entrance animations, gesture interactions (hover/tap/drag), scroll-based reveals, and layout transitions using spring physics and natural timing. Do NOT use for CSS-only transitions (use native CSS), static sites without JavaScript, Vue animations (use motion-v variant instead), or SVG/Canvas complex animations (GSAP better suited).

# Motion Dev Animations

> **Motion.dev** - 10M+ downloads/month, successor to Framer Motion
> 120fps GPU-accelerated animations for React, Next.js, Svelte, Astro, Vue

## Purpose

Generate production-grade animations using Motion.dev following Apple/Jon Ive principles:
**Purposeful** (serves function) | **Smooth** (120fps) | **Accessible** (reduced-motion) | **Performant** (GPU-only) | **Elegant** (subtle) | **Consistent** (unified timing)

## When to Use

✅ **Use for**:
- React 19+/Next.js 15+/Svelte 5+/Astro 4+ animation implementation
- Scroll effects (parallax, reveal), gestures (hover, drag, tap), layout animations
- Hero sections, cards, micro-interactions requiring 60fps+ performance
- Projects needing spring physics, natural motion, accessibility

❌ **Don't use for**:
- CSS-only transitions (use native `transition` property)
- Static sites without JavaScript frameworks
- Vue projects (use `motion-v` package - different API)
- SVG/Canvas complex animations (GSAP better suited)
- Form-only CRUD apps (overkill)

## Workflow: Clarify → Plan → Implement → Verify

### Step 1: Clarify Requirements
Determine project context and animation goals:
- Framework (React 19+, Next.js 15+, Svelte 5+, Astro 4+)
- Animation type (entrance, gesture, scroll, layout)
- Design goal (subtle, prominent, playful, professional)
- Performance constraints (target device, bundle limits, accessibility requirements)
- Trigger mechanism (mount, viewport, user interaction)

### Step 2: Plan Animation Strategy
Define implementation approach:
- Components to animate (headers, cards, buttons, sections)
- Motion patterns (fade, slide, scale, spring, parallax)
- Timing specifications (duration, delay, stagger intervals)
- Physics parameters (stiffness: 300-400, damping: 20, mass: 1)
- Accessibility fallbacks (prefers-reduced-motion alternatives)

### Step 3: Implement in Phases
Build animations incrementally:
- **Setup**: Install Motion.dev, configure imports, prepare component structure
- **Core Animation**: Apply motion properties (initial, animate, transition)
- **Refinement**: Tune timing, easing curves, spring physics for natural feel
- **Accessibility**: Add reduced-motion detection, keyboard navigation support
- **Optimization**: Verify GPU-acceleration, minimize bundle size, test performance

### Step 4: Verify Quality Standards
Check against requirements:
- **Performance**: ≥60fps (Chrome DevTools → Performance tab)
- **Layout Stability**: CLS = 0 (Lighthouse audit)
- **Accessibility**: Honors prefers-reduced-motion (system settings test)
- **Keyboard Navigation**: All interactive elements keyboard-accessible
- **Mobile Responsive**: Touch-friendly gestures, tested on iOS/Android

## Animation Pattern Decision Tree

```
INPUT: What should animate?

├─ ENTRANCE (page load, mount)
│   → Pattern: initial={{opacity: 0, y: 20}} animate={{opacity: 1, y: 0}}
│   → Timing: 0.6-0.8s, ease: [0.22, 1, 0.36, 1]
│   → Stagger: 0.1-0.2s between elements
│   → Example: ./examples/hero-fade-up.md
│
├─ GESTURE (hover, tap, drag)
│   → Pattern: whileHover={{scale: 1.05}}, whileTap={{scale: 0.95}}
│   → Physics: Spring (stiffness: 300-400, damping: 20)
│   → Timing: Instant response (no duration)
│   → Examples: ./examples/card-hover.md, ./examples/magnetic-button.md
│
├─ SCROLL (reveal, parallax)
│   → Pattern: whileInView + viewport OR useScroll + useTransform
│   → Trigger: viewport={{once: true, amount: 0.3}}
│   → Performance: Transform/opacity only
│   → Examples: ./examples/scroll-reveal.md, ./examples/parallax-layers.md
│
└─ LAYOUT (reorder, expand)
    → Pattern: layout prop (auto FLIP)
    → Shared: layoutId="id" for morphing
    → Caveat: Only animates transforms
```

## Common Patterns (Copy-Paste Ready)

### Pattern 1: Fade Up Entrance
```tsx
<motion.div
  initial={{ opacity: 0, y: 20 }}
  animate={{ opacity: 1, y: 0 }}
  transition={{ duration: 0.6, ease: [0.22, 1, 0.36, 1] }}
/>
```

### Pattern 2: Hover Card
```tsx
<motion.div
  whileHover={{ y: -8, boxShadow: "0 20px 40px rgba(0,0,0,0.12)" }}
  transition={{ type: "spring", stiffness: 300, damping: 20 }}
/>
```

### Pattern 3: Scroll Reveal
```tsx
<motion.div
  initial={{ opacity: 0, y: 50 }}
  whileInView={{ opacity: 1, y: 0 }}
  viewport={{ once: true, amount: 0.3 }}
/>
```

**More patterns**: Staggered lists, exit animations, layout transitions → `./examples/` directory

## Error Handling

| Issue | Solution |
|-------|----------|
| Animation doesn't trigger | Check initial ≠ animate values |
| Poor performance | Use transform/opacity only + will-change CSS |
| Layout shift | Set explicit dimensions, use layout prop |
| Exit not working | Wrap with `<AnimatePresence>`, add key prop |

## Implementation Best Practices

1. **Start simple** → Build from fade + slide, add complexity incrementally
2. **Extract variants** → Define animation states as named variants for maintainability
3. **Prefer spring physics** → Default to spring transitions (more natural than tween)
4. **Stagger list items** → Use staggerChildren (0.1-0.2s) for rhythm and hierarchy
5. **Test mobile thoroughly** → Verify touch gestures, performance on iOS/Android devices
6. **Include reduced-motion** → Always provide prefers-reduced-motion fallback animations
7. **Profile performance** → Use Chrome DevTools Performance tab, target ≥60fps

## Design Philosophy (Apple/Jon Ive Principles)

Apply these design principles to all animations:

- **Simplicity**: Use 200-400ms durations, minimize simultaneous motion, prefer transform properties
- **Natural Physics**: Implement spring-based transitions, avoid linear easing, apply mass-based movement
- **Purposeful Motion**: Guide user attention, provide interaction feedback, establish visual hierarchy
- **Elegant Restraint**: Apply "less is more" principle, maintain consistent timing, respect user motion preferences
