Motion

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 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 → Known Issue:

• Motion has build compatibility issues with Wrangler (GitHub issue #2918)
• Workaround: Use framer-motion v12.23.24 instead (same API, works with Workers)

3D Animations → Use dedicated 3D library:

• Three.js for WebGL
• React Three Fiber for React + Three.js

Core Concepts

1. The motion Component

Transform any HTML/SVG element into an animatable component:

import { motion } from "motion/react"

// Basic animation
<motion.div
  initial={{ opacity: 0, y: 20 }}
  animate={{ opacity: 1, y: 0 }}
  transition={{ duration: 0.5 }}
>
  Content fades in and slides up
</motion.div>

// Gesture controls
<motion.button
  whileHover={{ scale: 1.1 }}
  whileTap={{ scale: 0.95 }}
>
  Click me
</motion.button>

Props:

• initial: Starting state (object or variant name)
• animate: Target state (object or variant name)
• exit: Unmounting state (requires AnimatePresence)
• transition: Timing/easing configuration
• whileHover, whileTap, whileFocus: Gesture states
• whileInView: Viewport-triggered animation
• drag: Enable dragging ("x", "y", or true for both)
• layout: Enable FLIP layout animations

2. Variants (Animation Orchestration)

Named animation states that propagate through component tree:

const container = {
  hidden: { opacity: 0 },
  show: {
    opacity: 1,
    transition: {
      staggerChildren: 0.1, // Delay between each child
      delayChildren: 0.2,   // Initial delay before children
    }
  }
}

const item = {
  hidden: { opacity: 0, y: 20 },
  show: { opacity: 1, y: 0 }
}

<motion.ul variants={container} initial="hidden" animate="show">
  {items.map(item => (
    <motion.li key={item.id} variants={item}>
      {item.text}
    </motion.li>
  ))}
</motion.ul>

Benefits:

• Clean, declarative API
• Automatic choreography (stagger, delay, sequence)
• Reusable animation states
• Reduced prop drilling

3. 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>

4. Layout Animations (FLIP)

Automatically animate layout changes:

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

How it works:

• Calculates First position before change
• Applies change immediately (Last position)
• Inverts transform to match first position
• Plays animation to last position

Special Props:

• layoutId: Connect separate elements for shared transitions
• layoutScroll: Fix animations in scrollable containers
• layoutRoot: Fix animations in fixed-position elements

5. 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.

6. Gestures

<motion.div
  drag="x"
  dragConstraints={{ left: -200, right: 200 }}
  dragElastic={0.2}
  dragMomentum={false}
  info) => console.log(info.offset.x)}
>
  Drag me horizontally
</motion.div>

Available Gestures:

• whileHover: Mouse enter/leave (fixes sticky :hover on touch)
• whileTap: Pointer down (works on touch and mouse)
• whileFocus: Keyboard focus
• whileDrag: While dragging
• whileInView: While in viewport
• drag: Enable dragging with constraints and momentum

7. Spring Physics

Natural, physics-based easing:

<motion.div
  animate={{ x: 100 }}
  transition={{
    type: "spring",
    stiffness: 100,  // Higher = more sudden
    damping: 10,     // Higher = less oscillation (0 = infinite)
    mass: 1,         // Higher = more lethargic
  }}
/>

Presets:

• Default: { stiffness: 100, damping: 10 }
• Bouncy: { stiffness: 300, damping: 10 }
• Smooth: { stiffness: 100, damping: 20 }

Integration Guides

Vite + React + TypeScript

Installation:

pnpm create vite my-app --template react-ts
cd my-app
pnpm add motion

Import:

import { motion } from "motion/react"

Example Component:

import { motion } from "motion/react"

export function AnimatedButton() {
  return (
    <motion.button
      whileHover={{ scale: 1.1 }}
      whileTap={{ scale: 0.95 }}
      className="px-4 py-2 bg-blue-600 text-white rounded"
    >
      Hover and click me
    </motion.button>
  )
}

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 (⚠️ Compatibility Issue)

Problem: Motion has build errors with Wrangler (GitHub issue #2918).

Workaround: Use framer-motion v12.23.24 instead:

pnpm add framer-motion

Import stays the same:

import { motion } from "framer-motion"

Status: Monitor GitHub issue for resolution. The API is identical between motion and framer-motion v12.x.

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

User Settings Locations:

• macOS: System Settings → Accessibility → Display → Reduce motion
• Windows: Settings → Ease of Access → Display → Show animations
• iOS: Settings → Accessibility → Motion
• Android 9+: Settings → Accessibility → Remove animations

Implementation:

import { MotionConfig } from "motion/react"

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

What it does:

• When user enables reduced motion, Motion uses instant transitions
• reducedMotion value is "user" (respects OS setting)
• Can override with "always" (force instant) or "never" (ignore setting)

⚠️ Known Issue: reducedMotion doesn't affect AnimatePresence components (GitHub issue #1567).

Workaround:

const prefersReducedMotion = window.matchMedia("(prefers-reduced-motion: reduce)").matches

<AnimatePresence>
  {isVisible && (
    <motion.div
      initial={{ opacity: prefersReducedMotion ? 1 : 0 }}
      animate={{ opacity: 1 }}
      exit={{ opacity: prefersReducedMotion ? 1 : 0 }}
      transition={{ duration: prefersReducedMotion ? 0 : 0.3 }}
    >
      Content
    </motion.div>
  )}
</AnimatePresence>

Keyboard Support

Motion gestures work with keyboard:

<motion.button
  whileFocus={{ scale: 1.1 }}
  whileTap={{ scale: 0.95 }}
  tabIndex={0}
>
  Keyboard accessible
</motion.button>

Focus states:

• whileFocus: Triggered by Tab key or programmatic focus
• Works with screen readers
• Respects browser focus ring

Common Patterns

Pattern 1: Modal Dialog

import { motion, AnimatePresence } from "motion/react"

function Modal({ isOpen, onClose, children }) {
  return (
    <AnimatePresence>
      {isOpen && (
        <>
          {/* Backdrop */}
          <motion.div
            key="backdrop"
            initial={{ opacity: 0 }}
            animate={{ opacity: 1 }}
            exit={{ opacity: 0 }}
           
            className="fixed inset-0 bg-black/50 z-40"
          />

          {/* Dialog */}
          <motion.dialog
            key="dialog"
            initial={{ opacity: 0, scale: 0.9, y: 20 }}
            animate={{ opacity: 1, scale: 1, y: 0 }}
            exit={{ opacity: 0, scale: 0.9, y: 20 }}
            className="fixed inset-0 m-auto w-96 h-64 bg-white rounded-lg shadow-xl z-50"
          >
            {children}
          </motion.dialog>
        </>
      )}
    </AnimatePresence>
  )
}

Pattern 2: Accordion

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

function Accordion({ title, children }) {
  const [isOpen, setIsOpen] = useState(false)

  return (
    <div>
      <button => setIsOpen(!isOpen)}>{title}</button>
      <motion.div
        initial={false}
        animate={{ height: isOpen ? "auto" : 0 }}
        style={{ overflow: "hidden" }}
      >
        <div className="p-4">{children}</div>
      </motion.div>
    </div>
  )
}

Pattern 3: Drag-and-Drop Carousel

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

function Carousel({ images }) {
  const constraintsRef = useRef(null)

  return (
    <div ref={constraintsRef} className="overflow-hidden">
      <motion.div
        drag="x"
        dragConstraints={constraintsRef}
        dragElastic={0.1}
        className="flex gap-4"
      >
        {images.map(img => (
          <motion.img
            key={img.id}
            src={img.url}
            className="w-64 h-64 object-cover rounded-lg"
            whileHover={{ scale: 1.05 }}
          />
        ))}
      </motion.div>
    </div>
  )
}

Pattern 4: Scroll-Triggered Reveal

import { motion } from "motion/react"

function FadeInSection({ children }) {
  return (
    <motion.div
      initial={{ opacity: 0, y: 50 }}
      whileInView={{ opacity: 1, y: 0 }}
      viewport={{ once: true, margin: "-100px" }}
      transition={{ duration: 0.5 }}
    >
      {children}
    </motion.div>
  )
}

Pattern 5: Parallax Hero

import { useScroll, useTransform, motion } from "motion/react"

function ParallaxHero() {
  const { scrollYProgress } = useScroll()

  const y1 = useTransform(scrollYProgress, [0, 1], [0, -300])
  const y2 = useTransform(scrollYProgress, [0, 1], [0, -150])

  return (
    <div className="relative h-screen overflow-hidden">
      <motion.div style={{ y: y1 }} className="absolute inset-0">
        <img src="/background.jpg" className="w-full h-full object-cover" />
      </motion.div>
      <motion.div style={{ y: y2 }} className="relative z-10">
        <h1>Hero Title</h1>
      </motion.div>
    </div>
  )
}

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

Symptom: Wrangler build fails when using motion package.

Solution: Use framer-motion v12.23.24 instead:

pnpm add framer-motion

GitHub issue: #2918 (monitor for resolution)

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 Not Working with AnimatePresence

Symptom: MotionConfig reducedMotion doesn't disable AnimatePresence animations.

Solution: Manual check:

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

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.
