name: framer-motion description: Framer Motion performance optimization guidelines. This skill should be used when writing, reviewing, or refactoring React animations with Framer Motion to ensure optimal performance patterns. Triggers on tasks involving motion components, animations, gestures, layout transitions, scroll-linked effects, and SVG animations.

Community Framer Motion Best Practices

Comprehensive performance optimization guide for Framer Motion animations in React applications. Contains 42 rules across 9 categories, prioritized by impact to guide automated refactoring and code generation.

When to Apply

Reference these guidelines when:

• Adding animations to React components with Framer Motion
• Optimizing bundle size for animation-heavy applications
• Preventing unnecessary re-renders during animations
• Implementing layout transitions or shared element animations
• Building scroll-linked or gesture-based interactions

Rule Categories by Priority

Priority	Category	Impact	Prefix
1	Bundle Optimization	CRITICAL	bundle-
2	Re-render Prevention	CRITICAL	rerender-
3	Animation Properties	HIGH	anim-
4	Layout Animations	HIGH	layout-
5	Scroll Animations	MEDIUM-HIGH	scroll-
6	Gesture Optimization	MEDIUM	gesture-
7	Spring & Physics	MEDIUM	spring-
8	SVG & Path Animations	LOW-MEDIUM	svg-
9	Exit Animations	LOW	exit-

Quick Reference

1. Bundle Optimization (CRITICAL)

• bundle-lazy-motion - Use LazyMotion and m component instead of motion
• bundle-dynamic-features - Dynamically import motion features
• bundle-dom-animation - Use domAnimation for basic animations
• bundle-use-animate-mini - Use mini useAnimate for simple cases
• bundle-strict-mode - Enable strict mode to catch accidental imports

2. Re-render Prevention (CRITICAL)

• rerender-motion-value - Use useMotionValue instead of useState
• rerender-use-transform - Derive values with useTransform
• rerender-stable-callbacks - Keep animation callbacks stable
• rerender-variants-object - Define variants outside component
• rerender-animate-prop - Use stable animate values
• rerender-motion-value-event - Use motion value events

3. Animation Properties (HIGH)

• anim-transform-properties - Animate transform properties
• anim-opacity-filter - Prefer opacity and filter for visual effects
• anim-hardware-acceleration - Leverage hardware acceleration
• anim-will-change - Use willChange prop judiciously
• anim-independent-transforms - Animate transforms independently
• anim-keyframes-array - Use keyframe arrays for sequences

4. Layout Animations (HIGH)

• layout-dependency - Use layoutDependency to limit measurements
• layout-position-size - Use layout="position" or "size" appropriately
• layout-group - Group related layout animations
• layout-id-shared - Use layoutId for shared element transitions
• layout-scroll - Add layoutScroll to scrollable ancestors

5. Scroll Animations (MEDIUM-HIGH)

• scroll-use-scroll - Use useScroll hook for scroll-linked animations
• scroll-use-spring-smooth - Smooth scroll animations with useSpring
• scroll-element-tracking - Track specific elements entering viewport
• scroll-offset-configuration - Configure scroll offsets
• scroll-container-ref - Track scroll within specific containers

6. Gesture Optimization (MEDIUM)

• gesture-while-props - Use whileHover/whileTap instead of handlers
• gesture-variants-flow - Let gesture variants flow to children
• gesture-drag-constraints - Use dragConstraints ref for boundaries
• gesture-drag-elastic - Configure dragElastic for natural feel
• gesture-tap-cancel - Use onTapCancel for interrupted gestures

7. Spring & Physics (MEDIUM)

• spring-physics-based - Use physics-based springs for interruptibility
• spring-damping-ratio - Configure damping to control oscillation
• spring-mass-inertia - Adjust mass for heavier/lighter feel
• spring-use-spring-hook - Use useSpring for reactive values

8. SVG & Path Animations (LOW-MEDIUM)

• svg-path-length - Use pathLength for line drawing animations
• svg-motion-components - Use motion.path and motion.circle
• svg-viewbox-animation - Animate viewBox for zoom effects
• svg-morph-matching-points - Match point counts for morphing

9. Exit Animations (LOW)

• exit-animate-presence - Wrap conditional renders with AnimatePresence
• exit-unique-keys - Provide unique keys for AnimatePresence children
• exit-mode-wait - Use mode="wait" for sequential transitions
