What this skill tells the agent

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)

Recommended Stack: 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 instead: 3.28 KB vs 34 KB)
  • Static content without interactions
  • Cloudflare Workers (historically needed the framer-motion alias; with motion v12.43+ the main package works on Workers — see Known Issues)
  • 3D animations (use Three.js or React Three Fiber instead)

Installation

Latest Stable Version

bun add motion  # preferred
# or: npm install motion
# or: yarn add motion

Current Version: 12.43.0 (verified 2026-08-03)

Note: motion is the current package name. framer-motion is a deprecated alias that republishes the same code; it still works and is maintained as an install-time alias (notably useful as a Cloudflare Workers build workaround), but new projects should install motion.

Alternative for Cloudflare Workers:

# Use framer-motion if deploying to Cloudflare Workers
bun add framer-motion
# or: npm install framer-motion

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. 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 v12.43.0 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):
