# 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`](references/bundle-lazy-motion.md) - Use LazyMotion and m component instead of motion
- [`bundle-dynamic-features`](references/bundle-dynamic-features.md) - Dynamically import motion features
- [`bundle-dom-animation`](references/bundle-dom-animation.md) - Use domAnimation for basic animations
- [`bundle-use-animate-mini`](references/bundle-use-animate-mini.md) - Use mini useAnimate for simple cases
- [`bundle-strict-mode`](references/bundle-strict-mode.md) - Enable strict mode to catch accidental imports

### 2. Re-render Prevention (CRITICAL)

- [`rerender-motion-value`](references/rerender-motion-value.md) - Use useMotionValue instead of useState
- [`rerender-use-transform`](references/rerender-use-transform.md) - Derive values with useTransform
- [`rerender-stable-callbacks`](references/rerender-stable-callbacks.md) - Keep animation callbacks stable
- [`rerender-variants-object`](references/rerender-variants-object.md) - Define variants outside component
- [`rerender-animate-prop`](references/rerender-animate-prop.md) - Use stable animate values
- [`rerender-motion-value-event`](references/rerender-motion-value-event.md) - Use motion value events

### 3. Animation Properties (HIGH)

- [`anim-transform-properties`](references/anim-transform-properties.md) - Animate transform properties
- [`anim-opacity-filter`](references/anim-opacity-filter.md) - Prefer opacity and filter for visual effects
- [`anim-hardware-acceleration`](references/anim-hardware-acceleration.md) - Leverage hardware acceleration
- [`anim-will-change`](references/anim-will-change.md) - Use willChange prop judiciously
- [`anim-independent-transforms`](references/anim-independent-transforms.md) - Animate transforms independently
- [`anim-keyframes-array`](references/anim-keyframes-array.md) - Use keyframe arrays for sequences

### 4. Layout Animations (HIGH)

- [`layout-dependency`](references/layout-dependency.md) - Use layoutDependency to limit measurements
- [`layout-position-size`](references/layout-position-size.md) - Use layout="position" or "size" appropriately
- [`layout-group`](references/layout-group.md) - Group related layout animations
- [`layout-id-shared`](references/layout-id-shared.md) - Use layoutId for shared element transitions
- [`layout-scroll`](references/layout-scroll.md) - Add layoutScroll to scrollable ancestors

### 5. Scroll Animations (MEDIUM-HIGH)

- [`scroll-use-scroll`](references/scroll-use-scroll.md) - Use useScroll hook for scroll-linked animations
- [`scroll-use-spring-smooth`](references/scroll-use-spring-smooth.md) - Smooth scroll animations with useSpring
- [`scroll-element-tracking`](references/scroll-element-tracking.md) - Track specific elements entering viewport
- [`scroll-offset-configuration`](references/scroll-offset-configuration.md) - Configure scroll offsets
- [`scroll-container-ref`](references/scroll-container-ref.md) - Track scroll within specific containers

### 6. Gesture Optimization (MEDIUM)

- [`gesture-while-props`](references/gesture-while-props.md) - Use whileHover/whileTap instead of handlers
- [`gesture-variants-flow`](references/gesture-variants-flow.md) - Let gesture variants flow to children
- [`gesture-drag-constraints`](references/gesture-drag-constraints.md) - Use dragConstraints ref for boundaries
- [`gesture-drag-elastic`](references/gesture-drag-elastic.md) - Configure dragElastic for natural feel
- [`gesture-tap-cancel`](references/gesture-tap-cancel.md) - Use onTapCancel for interrupted gestures

### 7. Spring & Physics (MEDIUM)

- [`spring-physics-based`](references/spring-physics-based.md) - Use physics-based springs for interruptibility
- [`spring-damping-ratio`](references/spring-damping-ratio.md) - Configure damping to control oscillation
- [`spring-mass-inertia`](references/spring-mass-inertia.md) - Adjust mass for heavier/lighter feel
- [`spring-use-spring-hook`](references/spring-use-spring-hook.md) - Use useSpring for reactive values

### 8. SVG & Path Animations (LOW-MEDIUM)

- [`svg-path-length`](references/svg-path-length.md) - Use pathLength for line drawing animations
- [`svg-motion-components`](references/svg-motion-components.md) - Use motion.path and motion.circle
- [`svg-viewbox-animation`](references/svg-viewbox-animation.md) - Animate viewBox for zoom effects
- [`svg-morph-matching-points`](references/svg-morph-matching-points.md) - Match point counts for morphing

### 9. Exit Animations (LOW)

- [`exit-animate-presence`](references/exit-animate-presence.md) - Wrap conditional renders with AnimatePresence
- [`exit-unique-keys`](references/exit-unique-keys.md) - Provide unique keys for AnimatePresence children
- [`exit-mode-wait`](references/exit-mode-wait.md) - Use mode="wait" for sequential transitions
