Motion Animation Library Skill

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

Installation

Latest Stable Version

# Using pnpm (recommended)
pnpm add motion

# Using npm
npm install motion

# Using yarn
yarn add motion

Current Version: 12.24.12 (verified 2026-01-09)

Note for Cloudflare Workers:

# Both packages work with Cloudflare Workers (issue #2918 fixed Dec 2024)
pnpm add motion
# OR
pnpm add framer-motion  # Same version, same API

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)

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:

Modal Dialog - AnimatePresence with backdrop + dialog exit animations
Accordion - Animate height with height: "auto"
Drag Carousel - drag="x" with dragConstraints
Scroll Reveal - whileInView with viewport margin
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.
