# 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 19.2, Next.js 16.1, Vite 7.3, 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` skill instead:
- Todo list add/remove (auto-animate: 3.28 KB vs motion: 34 KB)
- Search results filtering
- Shopping cart items
- Notification toasts
- Basic accordions without gestures

**Static Content**:
- No user interaction or animations needed
- Server-rendered content without client interactivity

**Cloudflare Workers Deployment** → ✅ **Fixed (Dec 2024)**:
- Previous build compatibility issues resolved (GitHub issue #2918 closed as completed)
- Motion now works directly with Wrangler - no workaround needed
- Both `motion` and `framer-motion` v12.23.24 work correctly

**3D Animations** → Use dedicated 3D library:
- Three.js for WebGL
- React Three Fiber for React + Three.js

  - `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)

---

## Core Concepts

### 1. AnimatePresence (Exit Animations)

Enables animations when components unmount:

```tsx
import { AnimatePresence } from "motion/react"

<AnimatePresence>
  {isVisible && (
    <motion.div
      key="modal"
      initial={{ opacity: 0 }}
      animate={{ opacity: 1 }}
      exit={{ opacity: 0 }}
    >
      Modal content
    </motion.div>
  )}
</AnimatePresence>
```

**Critical Rules:**
- AnimatePresence **must stay mounted** (don't wrap in conditional)
- All children **must have unique `key` props**
- AnimatePresence **wraps the conditional**, not the other way around

**Common Mistake** (exit animation won't play):
```tsx
// ❌ Wrong - AnimatePresence unmounts with condition
{isVisible && (
  <AnimatePresence>
    <motion.div>Content</motion.div>
  </AnimatePresence>
)}

// ✅ Correct - AnimatePresence stays mounted
<AnimatePresence>
  {isVisible && <motion.div key="unique">Content</motion.div>}
</AnimatePresence>
```

### 2. Layout Animations

**Special Props:**
- `layout`: Enable FLIP layout animations
- `layoutId`: Connect separate elements for shared transitions
- `layoutScroll`: Fix animations in scrollable containers (see Issue #5)
- `layoutRoot`: Fix animations in fixed-position elements (see Issue #7)

```tsx
<motion.div layout>
  {isExpanded ? <FullContent /> : <Summary />}
</motion.div>
```

### 3. Scroll Animations

#### Viewport-Triggered (whileInView)
```tsx
<motion.div
  initial={{ opacity: 0, y: 50 }}
  whileInView={{ opacity: 1, y: 0 }}
  viewport={{ once: true, margin: "-100px" }}
>
  Fades in when 100px from entering viewport
</motion.div>
```

#### Scroll-Linked (useScroll)
```tsx
import { useScroll, useTransform } from "motion/react"

const { scrollYProgress } = useScroll()
const y = useTransform(scrollYProgress, [0, 1], [0, -300])

<motion.div style={{ y }}>
  Moves up 300px as user scrolls page
</motion.div>
```

**Performance**: Uses native ScrollTimeline API when available for hardware acceleration.

---

## Integration Guides

### Vite + React + TypeScript

```bash
pnpm add motion
```

Import: `import { motion } from "motion/react"`

**No Vite configuration needed** - works out of the box.

### Next.js App Router (Recommended Pattern)

**Key Requirement**: Motion only works in **Client Components** (not Server Components).

**Step 1: Create Client Component Wrapper**

`src/components/motion-client.tsx`:
```tsx
"use client"

// Optimized import for Next.js (reduces client JS)
import * as motion from "motion/react-client"

export { motion }
```

**Step 2: Use in Server Components**

`src/app/page.tsx`:
```tsx
import { motion } from "@/components/motion-client"

export default function Page() {
  return (
    <motion.div
      initial={{ opacity: 0 }}
      animate={{ opacity: 1 }}
    >
      This works in Server Component (wrapper is client)
    </motion.div>
  )
}
```

**Alternative: Direct Client Component**
```tsx
"use client"

import { motion } from "motion/react"

export function AnimatedCard() {
  return <motion.div>...</motion.div>
}
```

**Known Issues (Next.js 15+ + React 19)**:
- React 19 fully supported as of December 2025 (see Issue #11 for one StrictMode edge case)
- Most compatibility issues resolved in Motion 12.27.5
- AnimatePresence may fail with soft navigation
- Reorder component incompatible with Next.js routing and page-level scrolling (see Issue #10)

### Next.js Pages Router

Works without modifications:

```tsx
import { motion } from "motion/react"

export default function Page() {
  return <motion.div>No "use client" needed</motion.div>
}
```

### Tailwind CSS Integration

**Best Practice**: Let each library do what it does best.

- **Tailwind**: Static and responsive styling via `className`
- **Motion**: Animations via motion props

```tsx
<motion.button
  className="bg-blue-600 text-white px-4 py-2 rounded hover:bg-blue-700"
  whileHover={{ scale: 1.1 }}
  whileTap={{ scale: 0.95 }}
>
  Tailwind styles + Motion animations
</motion.button>
```

**⚠️ Remove Tailwind Transitions**: Causes stuttering/conflicts.
```tsx
// ❌ Wrong - Tailwind transition conflicts with Motion
<motion.div className="transition-all duration-300" animate={{ x: 100 }} />

// ✅ Correct - Remove Tailwind transition
<motion.div animate={{ x: 100 }} />
```

**Why**: Motion uses inline styles or native browser animations, both override Tailwind's CSS transitions.

### Cloudflare Workers (✅ Now Supported)

**Status**: ✅ **Fixed as of December 2024** (GitHub issue #2918 closed as completed)

**Installation**:
```bash
# Motion now works directly with Cloudflare Workers
pnpm add motion
```

**Import:**
```tsx
import { motion } from "motion/react"
```

**Historical Note**: Prior to December 2024, there was a Wrangler ESM resolution issue requiring use of `framer-motion` as a workaround. This has been resolved, and both packages now work correctly with Cloudflare Workers.

## Performance Optimization

### 1. Reduce Bundle Size with LazyMotion

**Problem**: Full `motion` component is ~34 KB minified+gzipped.

**Solution**: Use `LazyMotion` + `m` component for 4.6 KB:

```tsx
import { LazyMotion, domAnimation, m } from "motion/react"

function App() {
  return (
    <LazyMotion features={domAnimation}>
      {/* Use 'm' instead of 'motion' */}
      <m.div
        initial={{ opacity: 0 }}
        animate={{ opacity: 1 }}
      >
        Only 4.6 KB!
      </m.div>
    </LazyMotion>
  )
}
```

**How it works**: Loads animation features on-demand instead of bundling everything.

**Alternative (Smallest)**: `useAnimate` mini (2.3 KB):
```tsx
import { useAnimate } from "motion/react"

function Component() {
  const [scope, animate] = useAnimate()

  return <div ref={scope}>Smallest possible React animation</div>
}
```

### 2. Hardware Acceleration

**Add `willChange` for transforms:**
```tsx
<motion.div
  style={{ willChange: "transform" }}
  animate={{ x: 100, rotate: 45 }}
/>
```

**Also add for**: `opacity`, `backgroundColor`, `clipPath`, `filter`

**How it works**: Tells browser to optimize for animation, uses GPU compositing.

### 3. Large Lists → Use Virtualization

**Problem**: Animating 50-100+ items causes severe slowdown.

**Solutions:**
```bash
pnpm add react-window
# or
pnpm add react-virtuoso
# or
pnpm add @tanstack/react-virtual
```

**Pattern:**
```tsx
import { FixedSizeList } from 'react-window'
import { motion } from 'motion/react'

<FixedSizeList
  height={600}
  itemCount={1000}
  itemSize={50}
>
  {({ index, style }) => (
    <motion.div style={style} layout>
      Item {index}
    </motion.div>
  )}
</FixedSizeList>
```

**Why**: Only renders visible items, reduces DOM updates and memory usage.

### 4. Use `layout` Prop for FLIP Animations

Automatically animates layout changes without JavaScript calculation:

```tsx
<motion.div layout>
  {isExpanded ? <LargeContent /> : <SmallContent />}
</motion.div>
```

**Performance**: Hardware-accelerated via transforms, no reflow/repaint.

## Accessibility

### Respect `prefers-reduced-motion`

```tsx
import { MotionConfig } from "motion/react"

<MotionConfig reducedMotion="user">
  <App />
</MotionConfig>
```

**Options:**
- `"user"`: Respects OS setting (recommended)
- `"always"`: Force instant transitions
- `"never"`: Ignore user preference

**Note**: ✅ Fixed in Jan 2023 (GitHub #1567) - MotionConfig now works correctly with AnimatePresence.

---

## Common Patterns

**5 Production-Ready Patterns:**
1. **Modal Dialog** - AnimatePresence with backdrop + dialog exit animations
2. **Accordion** - Animate height with `height: "auto"`
3. **Drag Carousel** - `drag="x"` with `dragConstraints`
4. **Scroll Reveal** - `whileInView` with viewport margin
5. **Parallax Hero** - `useScroll` + `useTransform` for layered effects

See `references/common-patterns.md` for full code (15+ patterns).

## Known Issues & Solutions

### Issue 1: AnimatePresence Exit Not Working

**Error**: Exit animations don't play, components disappear instantly
**Source**: [GitHub Issue #3078](https://github.com/motiondivision/motion/issues/3078)

**Why It Happens**: AnimatePresence wrapped in conditional or missing `key` props. Defining `exit` props on staggered children inside modals can also prevent modal from unmounting (backdrop remains visible).

**Solution**:
```tsx
// ❌ Wrong - AnimatePresence wrapped in conditional
{isVisible && (
  <AnimatePresence>
    <motion.div>Content</motion.div>
  </AnimatePresence>
)}

// ✅ Correct - AnimatePresence stays mounted
<AnimatePresence>
  {isVisible && <motion.div key="unique">Content</motion.div>}
</AnimatePresence>

// ❌ Wrong - Staggered children with exit prevent modal removal
<AnimatePresence>
  {isOpen && (
    <Modal>
      <motion.ul>
        {items.map(item => (
          <motion.li
            key={item.id}
            exit={{ opacity: 1, scale: 1 }}  // ← Prevents modal unmount
          >
            {item.content}
          </motion.li>
        ))}
      </motion.ul>
    </Modal>
  )}
</AnimatePresence>

// ✅ Fix for modal - Remove exit from children or set duration: 0
<motion.li
  key={item.id}
  exit={{ opacity: 0, scale: 0.5, transition: { duration: 0 } }}
>
  {item.content}
</motion.li>
```

### Issue 2: Large List Performance

**Symptom**: 50-100+ animated items cause severe slowdown, browser freezes.

**Solution**: Use virtualization:
```bash
pnpm add react-window
```

See `references/performance-optimization.md` for full guide.

### Issue 3: Tailwind Transitions Conflict

**Symptom**: Animations stutter or don't work.

**Solution**: Remove `transition-*` classes:
```tsx
// ❌ Wrong
<motion.div className="transition-all" animate={{ x: 100 }} />

// ✅ Correct
<motion.div animate={{ x: 100 }} />
```

### Issue 4: Next.js "use client" Missing

**Symptom**: Build fails with "motion is not defined" or SSR errors.

**Solution**: Add `"use client"` directive:
```tsx
"use client"

import { motion } from "motion/react"
```

See `references/nextjs-integration.md` for App Router patterns.

### Issue 5: Scrollable Container Layout Animations

**Symptom**: Incomplete transitions when removing items from scrolled containers.

**Solution**: Add `layoutScroll` prop:
```tsx
<motion.div layoutScroll className="overflow-auto">
  {items.map(item => (
    <motion.div key={item.id} layout>
      {item.content}
    </motion.div>
  ))}
</motion.div>
```

### Issue 6: Cloudflare Workers Build Errors (✅ RESOLVED)

**Status**: ✅ **Fixed in December 2024** (GitHub issue #2918 closed as completed)

**Previous Symptom**: Wrangler build failed with React import errors when using `motion` package.

**Current State**: Motion now works correctly with Cloudflare Workers. No workaround needed.

**If you encounter build issues**: Ensure you're using Motion v12.23.24 or later and Wrangler v3+.

GitHub issue: #2918 (closed as completed Dec 13, 2024)

### Issue 7: Fixed Position Layout Animations

**Symptom**: Layout animations in fixed elements have incorrect positioning.

**Solution**: Add `layoutRoot` prop:
```tsx
<motion.div layoutRoot className="fixed top-0 left-0">
  <motion.div layout>Content</motion.div>
</motion.div>
```

### Issue 8: layoutId + AnimatePresence Unmounting

**Symptom**: Elements with `layoutId` inside AnimatePresence fail to unmount.

**Solution**: Wrap in `LayoutGroup` or avoid mixing exit + layout animations:
```tsx
import { LayoutGroup } from "motion/react"

<LayoutGroup>
  <AnimatePresence>
    {items.map(item => (
      <motion.div key={item.id} layoutId={item.id}>
        {item.content}
      </motion.div>
    ))}
  </AnimatePresence>
</LayoutGroup>
```

### Issue 9: Reduced Motion with AnimatePresence (✅ RESOLVED)

**Status**: ✅ **Fixed in January 2023** (GitHub issue #1567 closed via PR #1891)

**Previous Symptom**: MotionConfig reducedMotion setting didn't affect AnimatePresence animations.

**Current State**: MotionConfig now correctly applies reducedMotion to AnimatePresence components. The setting works as documented.

**Optional Manual Control**: If you need custom behavior beyond the built-in support:
```tsx
const prefersReducedMotion = window.matchMedia("(prefers-reduced-motion: reduce)").matches

<motion.div
  initial={{ opacity: prefersReducedMotion ? 1 : 0 }}
  animate={{ opacity: 1 }}
  transition={{ duration: prefersReducedMotion ? 0 : 0.3 }}
/>
```

GitHub issue: #1567 (closed as completed Jan 13, 2023)

### Issue 10: Reorder Component Limitations

**Error**: Reorder auto-scroll fails, doesn't work with Next.js routing
**Source**: [GitHub Issue #3469](https://github.com/motiondivision/motion/issues/3469), #2183, #2101

**Why It Happens**:
- **Page-level scrolling**: Reorder auto-scroll only works when `Reorder.Group` is inside element with `overflow: auto/scroll`, NOT when document itself is scrollable
- **Next.js routing**: Incompatible with Next.js routing system, causes random stuck states

**Prevention**:
```tsx
// ❌ Wrong - Page-level scrolling (auto-scroll fails)
<body style={{ height: "200vh" }}>
  <Reorder.Group values={items} onReorder={setItems}>
    {/* Auto-scroll doesn't trigger at viewport edges */}
  </Reorder.Group>
</body>

// ✅ Correct - Container with overflow
<div style={{ height: "300px", overflow: "auto" }}>
  <Reorder.Group values={items} onReorder={setItems}>
    {items.map(item => (
      <Reorder.Item key={item.id} value={item}>
        {item.content}
      </Reorder.Item>
    ))}
  </Reorder.Group>
</div>

// ✅ Alternative - Use DnD Kit for complex cases
// Motion docs officially recommend DnD Kit for:
// - Multi-row reordering
// - Dragging between columns
// - Page-level scrollable containers
// - Complex drag-and-drop interactions

// Install: pnpm add @dnd-kit/core @dnd-kit/sortable @dnd-kit/utilities
```

See `references/nextjs-integration.md` for full Next.js troubleshooting guide.

### Issue 11: React 19 StrictMode Drag Bug

**Error**: Drag gestures break when dragging from top to bottom in file trees
**Source**: [GitHub Issue #3169](https://github.com/motiondivision/motion/issues/3169)

**Why It Happens**: Only occurs with React 19 + StrictMode enabled + Ant Design components. Dragged element position breaks and appears offset. Does NOT occur in React 18 or React 19 without StrictMode. Only affects top-to-bottom drag (bottom-to-top works fine).

**Prevention**: Temporarily disable StrictMode for React 19 projects using drag gestures, or use React 18 if StrictMode is critical. Awaiting official fix from Motion team.

### Issue 12: Layout Animations in Scaled Containers

**Error**: Layout animations start from incorrect positions in scaled parent containers
**Source**: [GitHub Issue #3356](https://github.com/motiondivision/motion/issues/3356)

**Why It Happens**: Layout animation system uses scaled coordinates as if they were unscaled. Motion's layout animations work in pixels, while parent scale affects visual coordinates. The mismatch causes position calculation errors.

**Prevention (Community Workaround)**:
```tsx
// Use transformTemplate to correct for parent scale
const scale = 2; // Parent's transform scale value

<div style={{ transform: `scale(${scale})` }}>
  <motion.div
    layout
    transformTemplate={(latest, generated) => {
      const match = /translate3d\((.+)px,\s?(.+)px,\s?(.+)px\)/.exec(generated);
      if (match) {
        const [, x, y, z] = match;
        return `translate3d(${Number(x) / scale}px, ${Number(y) / scale}px, ${Number(z) / scale}px)`;
      }
      return generated;
    }}
  >
    Content
  </motion.div>
</div>
```

**Limitations**: Only works for layout animations only, doesn't fix other transforms, requires knowing parent scale value.

### Issue 13: AnimatePresence Exit Gets Stuck on Unmount

**Error**: Exit state stuck when child unmounts during exit animation
**Source**: [GitHub Issue #3243](https://github.com/motiondivision/motion/issues/3243)

**Why It Happens**: When child component inside AnimatePresence unmounts immediately after exit animation triggers, exit state gets stuck. Component incorrectly remains in "exit" state.

**Prevention**: Don't unmount motion components while AnimatePresence is handling their exit. Ensure motion.div stays mounted until exit completes. Use conditional rendering only on parent AnimatePresence children.

### Issue 14: Percentage Values Break Layout Animations in Flex Containers

**Error**: Layout animations teleport instantly instead of animating smoothly
**Source**: [GitHub Issue #3401](https://github.com/motiondivision/motion/issues/3401)

**Why It Happens**: Using percentage-based x values in initial prop breaks layout animations when container uses display flex with justify-content center. Motion's layout animations work in pixels, while CSS percentage transforms are resolved relative to element/parent. The coordinate system mismatch causes position recalculation mid-frame.

**Prevention**: Convert percentage to pixels before animation. Calculate container width and use pixel values instead of percentage strings.

### Issue 15: Sub-Pixel Precision Loss in popLayout Mode

**Error**: 1px layout shift just before exit transition starts
**Source**: [GitHub Issue #3260](https://github.com/motiondivision/motion/issues/3260)

**Why It Happens**: When using AnimatePresence with mode popLayout, exiting element dimensions are captured and reapplied as inline styles. Sub-pixel values from getBoundingClientRect are rounded to nearest integer, causing visible layout shift. Can cause text wrapping changes.

**Prevention**: Use whole pixel values only for dimensions, or avoid popLayout for sub-pixel-sensitive layouts. No perfect workaround exists.
