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 instead: 3.28 KB vs 34 KB)
Static content without interactions
Cloudflare Workers (use framer-motion v12.23.24 workaround - see Known Issues)
3D animations (use Three.js or React Three Fiber instead)

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 variants = {
  hidden: { opacity: 0, y: 20 },
  visible: { opacity: 1, y: 0 }
}

<motion.div variants={variants} initial="hidden" animate="visible">
  Content
</motion.div>

For advanced orchestration (staggerChildren, delayChildren, dynamic variants), load references/core-concepts-deep-dive.md.

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>

Special props: layoutId (shared element transitions), layoutScroll (scrollable containers), layoutRoot (fixed positioning).

For advanced patterns (LayoutGroup, layoutId orchestration), load references/core-concepts-deep-dive.md.

5. Scroll Animations

// Viewport-triggered
<motion.div
  initial={{ opacity: 0, y: 50 }}
  whileInView={{ opacity: 1, y: 0 }}
  viewport={{ once: true }}
>
  Fades in when entering viewport
</motion.div>

// Scroll-linked (parallax)
import { useScroll, useTransform } from "motion/react"
const { scrollYProgress } = useScroll()
const y = useTransform(scrollYProgress, [0, 1], [0, -300])
<motion.div style={{ y }}>Parallax effect</motion.div>

For advanced scroll patterns (useScroll offsets, useTransform easing, parallax layers), load references/core-concepts-deep-dive.md.

6. Gestures

<motion.div drag="x" dragConstraints={{ left: -200, right: 200 }}>
  Drag me
</motion.div>

Available: whileHover, whileTap, whileFocus, whileDrag, whileInView, drag.

For advanced drag controls (momentum, elastic, event handlers), load references/core-concepts-deep-dive.md.

7. Spring Physics

<motion.div
  animate={{ x: 100 }}
  transition={{ type: "spring", stiffness: 100, damping: 10 }}
/>

Common presets: Bouncy { stiffness: 300, damping: 10 }, Smooth { stiffness: 100, damping: 20 }.

For spring tuning (mass, visualizer, presets), load references/core-concepts-deep-dive.md.

Integration Guides

Vite: bun add motion → import { motion } from "motion/react" (works out of the box)

Next.js App Router: Requires "use client" directive or client component wrapper

"use client"
import { motion } from "motion/react"

Tailwind: ⚠️ Remove transition-* classes (causes conflicts with Motion animations)

Cloudflare Workers: Use framer-motion v12.23.24 instead (Motion has Wrangler build issues)

For complete integration guides (Next.js patterns, SSR, framework-specific issues), load references/nextjs-integration.md.

Performance Optimization

Bundle Size: Use LazyMotion (34 KB → 4.6 KB):

import { LazyMotion, domAnimation, m } from "motion/react"
<LazyMotion features={domAnimation}>
  <m.div>Only 4.6 KB!</m.div>
</LazyMotion>

Large Lists: Use virtualization (react-window, react-virtuoso) for 50+ animated items.

For complete optimization guide (hardware acceleration, memory profiling, production benchmarks), load references/performance-optimization.md.

Accessibility

Respect prefers-reduced-motion:

import { MotionConfig } from "motion/react"
<MotionConfig reducedMotion="user">
  <App />
</MotionConfig>

Keyboard Support: Use whileFocus for keyboard-triggered animations.

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

For complete accessibility guide (ARIA patterns, screen readers, AnimatePresence workaround, testing), load references/accessibility-guide.md.

Common Patterns

Modal Dialog (AnimatePresence + backdrop):

<AnimatePresence>
  {isOpen && (
    <motion.dialog exit={{ opacity: 0 }}>Content</motion.dialog>
  )}
</AnimatePresence>

Accordion (height animation):

<motion.div animate={{ height: isOpen ? "auto" : 0 }}>
  Content
</motion.div>

For 15+ production patterns (carousel, tabs, scroll reveal, parallax, notifications), load references/common-patterns.md.

Known Issues & Solutions

Issue 1: AnimatePresence Exit Not Working (MOST COMMON)

Symptom: Components disappear instantly without exit animation.

Solution: AnimatePresence must stay mounted, wrap the conditional (not be wrapped by it):

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

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

Issue 2: 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"

Issue 3: Tailwind Transitions Conflict

Symptom: Animations stutter or don't work.

Solution: Remove transition-* classes (Motion overrides CSS transitions):

// ❌ Wrong: <motion.div className="transition-all" animate={{ x: 100 }} />
// ✅ Correct: <motion.div animate={{ x: 100 }} />

Issue 4: Cloudflare Workers Build Errors

Symptom: Wrangler build fails when using motion package.

Solution: Use framer-motion v12.23.24 instead (GitHub issue #2918):

bun add framer-motion  # Same API, works with Workers

Issue 5: Large List Performance

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

Solution: Use virtualization (react-window, react-virtuoso).
