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

Installation

Latest Stable Version

Using pnpm (recommended)

pnpm add motion

Using npm

npm install motion

Using yarn

yarn add motion

Current Version: 12.23.24 (verified 2025-11-09)

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
