Motion Dev Animations

Motion.dev - 10M+ downloads/month, successor to Framer Motion 120fps GPU-accelerated animations for React, Next.js, Svelte, Astro, Vue

Purpose

Generate production-grade animations using Motion.dev following Apple/Jon Ive principles: Purposeful (serves function) | Smooth (120fps) | Accessible (reduced-motion) | Performant (GPU-only) | Elegant (subtle) | Consistent (unified timing)

When to Use

✅ Use for:

• React 19+/Next.js 15+/Svelte 5+/Astro 4+ animation implementation
• Scroll effects (parallax, reveal), gestures (hover, drag, tap), layout animations
• Hero sections, cards, micro-interactions requiring 60fps+ performance
• Projects needing spring physics, natural motion, accessibility

❌ Don't use for:

• CSS-only transitions (use native transition property)
• Static sites without JavaScript frameworks
• Vue projects (use motion-v package - different API)
• SVG/Canvas complex animations (GSAP better suited)
• Form-only CRUD apps (overkill)

Workflow: Clarify → Plan → Implement → Verify

Step 1: Clarify Requirements

Determine project context and animation goals:

• Framework (React 19+, Next.js 15+, Svelte 5+, Astro 4+)
• Animation type (entrance, gesture, scroll, layout)
• Design goal (subtle, prominent, playful, professional)
• Performance constraints (target device, bundle limits, accessibility requirements)
• Trigger mechanism (mount, viewport, user interaction)

Step 2: Plan Animation Strategy

Define implementation approach:

• Components to animate (headers, cards, buttons, sections)
• Motion patterns (fade, slide, scale, spring, parallax)
• Timing specifications (duration, delay, stagger intervals)
• Physics parameters (stiffness: 300-400, damping: 20, mass: 1)
• Accessibility fallbacks (prefers-reduced-motion alternatives)

Step 3: Implement in Phases

Build animations incrementally:

• Setup: Install Motion.dev, configure imports, prepare component structure
• Core Animation: Apply motion properties (initial, animate, transition)
• Refinement: Tune timing, easing curves, spring physics for natural feel
• Accessibility: Add reduced-motion detection, keyboard navigation support
• Optimization: Verify GPU-acceleration, minimize bundle size, test performance

Step 4: Verify Quality Standards

Check against requirements:

• Performance: ≥60fps (Chrome DevTools → Performance tab)
• Layout Stability: CLS = 0 (Lighthouse audit)
• Accessibility: Honors prefers-reduced-motion (system settings test)
• Keyboard Navigation: All interactive elements keyboard-accessible
• Mobile Responsive: Touch-friendly gestures, tested on iOS/Android

Animation Pattern Decision Tree

INPUT: What should animate?

├─ ENTRANCE (page load, mount)
│   → Pattern: initial={{opacity: 0, y: 20}} animate={{opacity: 1, y: 0}}
│   → Timing: 0.6-0.8s, ease: [0.22, 1, 0.36, 1]
│   → Stagger: 0.1-0.2s between elements
│   → Example: ./examples/hero-fade-up.md
│
├─ GESTURE (hover, tap, drag)
│   → Pattern: whileHover={{scale: 1.05}}, whileTap={{scale: 0.95}}
│   → Physics: Spring (stiffness: 300-400, damping: 20)
│   → Timing: Instant response (no duration)
│   → Examples: ./examples/card-hover.md, ./examples/magnetic-button.md
│
├─ SCROLL (reveal, parallax)
│   → Pattern: whileInView + viewport OR useScroll + useTransform
│   → Trigger: viewport={{once: true, amount: 0.3}}
│   → Performance: Transform/opacity only
│   → Examples: ./examples/scroll-reveal.md, ./examples/parallax-layers.md
│
└─ LAYOUT (reorder, expand)
    → Pattern: layout prop (auto FLIP)
    → Shared: layoutId="id" for morphing
    → Caveat: Only animates transforms

Common Patterns (Copy-Paste Ready)

Pattern 1: Fade Up Entrance

<motion.div
  initial={{ opacity: 0, y: 20 }}
  animate={{ opacity: 1, y: 0 }}
  transition={{ duration: 0.6, ease: [0.22, 1, 0.36, 1] }}
/>

Pattern 2: Hover Card

<motion.div
  whileHover={{ y: -8, boxShadow: "0 20px 40px rgba(0,0,0,0.12)" }}
  transition={{ type: "spring", stiffness: 300, damping: 20 }}
/>

Pattern 3: Scroll Reveal

<motion.div
  initial={{ opacity: 0, y: 50 }}
  whileInView={{ opacity: 1, y: 0 }}
  viewport={{ once: true, amount: 0.3 }}
/>

Error Handling

Implementation Best Practices

1. Start simple → Build from fade + slide, add complexity incrementally
2. Extract variants → Define animation states as named variants for maintainability
3. Prefer spring physics → Default to spring transitions (more natural than tween)
4. Stagger list items → Use staggerChildren (0.1-0.2s) for rhythm and hierarchy
5. Test mobile thoroughly → Verify touch gestures, performance on iOS/Android devices
6. Include reduced-motion → Always provide prefers-reduced-motion fallback animations
7. Profile performance → Use Chrome DevTools Performance tab, target ≥60fps

Design Philosophy (Apple/Jon Ive Principles)

Apply these design principles to all animations:

• Simplicity: Use 200-400ms durations, minimize simultaneous motion, prefer transform properties
• Natural Physics: Implement spring-based transitions, avoid linear easing, apply mass-based movement
• Purposeful Motion: Guide user attention, provide interaction feedback, establish visual hierarchy
• Elegant Restraint: Apply "less is more" principle, maintain consistent timing, respect user motion preferences
