# Motion Animation Library

## Overview

Motion (package: `motion`, formerly `framer-motion`) is the industry-standard React animation library used in production by thousands of applications. With 30,200+ GitHub stars and 300+ official examples, it provides a declarative API for creating sophisticated animations with minimal code.

**Key Capabilities:**

- **Gestures**: drag, hover, tap, pan, focus with cross-device support
- **Scroll Animations**: viewport-triggered, scroll-linked, parallax effects
- **Layout Animations**: FLIP technique for smooth layout changes, shared element transitions
- **Spring Physics**: Natural, customizable motion with physics-based easing
- **SVG**: Path morphing, line drawing, attribute animation
- **Exit Animations**: AnimatePresence for unmounting transitions
- **Performance**: Hardware-accelerated, ScrollTimeline API, bundle optimization (2.3 KB - 34 KB)

**Production Tested**: React 19, Next.js 15, Vite 6, Tailwind v4

## When to Use This Skill



### ✅ Use Motion When:

**Complex Interactions**:

- Drag-and-drop interfaces (sortable lists, kanban boards, sliders)
- Hover states with scale/rotation/color changes
- Tap feedback with bounce/squeeze effects
- Pan gestures for mobile-friendly controls

**Scroll-Based Animations**:

- Hero sections with parallax layers
- Scroll-triggered reveals (fade in as elements enter viewport)
- Progress bars linked to scroll position
- Sticky headers with scroll-dependent transforms

**Layout Transitions**:

- Shared element transitions between routes (card → detail page)
- Expand/collapse with automatic height animation
- Grid/list view switching with smooth repositioning
- Tab navigation with animated underline

**Advanced Features**:

- SVG line drawing animations
- Path morphing between shapes
- Spring physics for natural bounce
- Orchestrated sequences (staggered reveals)
- Modal dialogs with backdrop blur

**Bundle Optimization**:

- Need 2.3 KB animation library (useAnimate mini)
- Want to reduce Motion from 34 KB to 4.6 KB (LazyMotion)



### ❌ Don't Use Motion When:

- **Simple list animations** (use `auto-animate` instead: 3.28 KB vs 34 KB)
- **Static content** without interactions
- **Cloudflare Workers** (use `framer-motion` v12.23.24 workaround - see Known Issues)
- **3D animations** (use Three.js or React Three Fiber instead)

## Installation



### Latest Stable Version

```bash
bun add motion  # preferred
# or: npm install motion
# or: yarn add motion
```

**Current Version**: 12.23.24 (verified 2025-11-07)

**Alternative for Cloudflare Workers**:

```bash
# Use framer-motion if deploying to Cloudflare Workers
bun add framer-motion
# or: npm install framer-motion
```



### Package Information

- **Bundle Size**:
  - Full `motion` component: ~34 KB minified+gzipped
  - `LazyMotion` + `m` component: ~4.6 KB
  - `useAnimate` mini: 2.3 KB (smallest React animation library)
  - `useAnimate` hybrid: 17 KB
- **Dependencies**: React 18+ or React 19+
- **TypeScript**: Native support included (no @types package needed)
