name: motion description: | Build sophisticated React animations with Motion (formerly Framer Motion) - declarative animations, gestures (drag, hover, tap), scroll effects, spring physics, layout animations, and SVG manipulation. Optimize bundle size with LazyMotion (4.6 KB) or useAnimate mini (2.3 KB).

Use when: adding drag-and-drop interactions, creating scroll-triggered animations, implementing modal dialogs with transitions, building carousels with momentum, animating page/route transitions, creating parallax hero sections, implementing accordions with smooth expand/collapse, or optimizing animation bundle sizes. For simple list animations, use auto-animate skill instead (3.28 KB vs 34 KB).

Troubleshoot: AnimatePresence exit not working, large list performance issues, Tailwind transition conflicts, Next.js "use client" errors, scrollable container layout issues, or Cloudflare Workers build errors (resolved Dec 2024).

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 16, Vite 7, 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

Core Concepts

1. AnimatePresence (Exit Animations)

Enables animations when components unmount:

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):

// ❌ 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)

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

3. Scroll Animations

Viewport-Triggered (whileInView)

<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)

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

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:

"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:

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

"use client"

import { motion } from "motion/react"

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

Known Issues (Next.js 15 + React 19):

• Most compatibility issues marked COMPLETED (update to latest)
• AnimatePresence may fail with soft navigation
• Reorder component incompatible with Next.js routing

Next.js Pages Router

Works without modifications:

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

<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.

// ❌ 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:

# Motion now works directly with Cloudflare Workers
pnpm add motion

Import:

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:

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):

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:

<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:

pnpm add react-window
# or
pnpm add react-virtuoso
# or
pnpm add @tanstack/react-virtual

Pattern:

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:

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

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

Accessibility

Respect prefers-reduced-motion

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

Symptom: Components disappear instantly without exit animation.

Cause: AnimatePresence wrapped in conditional or missing key props.

Solution:

// ❌ Wrong
{isVisible && (
  <AnimatePresence>
    <motion.div>Content</motion.div>
  </AnimatePresence>
)}

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

Issue 2: Large List Performance

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

Solution: Use virtualization:

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:

// ❌ 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:

"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:

<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:

<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:

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:

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 in Next.js

Symptom: Reorder component doesn't work with Next.js routing, random stuck states.

Solution: Use alternative drag-to-reorder implementations or avoid Reorder in Next.js.

GitHub issues: #2183, #2101

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