💭 Why I Built This

As a developer who's always been fascinated by smooth, performant animations, I found myself constantly frustrated with existing solutions. They were either too bloated, lacked TypeScript support, or didn't give me the granular control I craved. So I decided to build Mayonation - not just another animation library, but a reflection of how I believe web animations should work.

This project represents months of deep diving into animation mathematics, browser optimization techniques, and API design. Every line of code has been crafted with performance, developer experience, and maintainability in mind.

✨ What Makes It Special

• 🎯 Built for Developers - Clean, intuitive API that actually makes sense
• 🚀 Performance Obsessed - <5kb gzipped, 60fps guaranteed, GPU-accelerated
• 🎮 Timeline Magic - Complex choreographed animations made simple
• 🎨 Versatile - CSS properties, transforms, SVG paths - animate everything
• 📦 TypeScript First - Written in TypeScript, with full type safety
• 🔧 Zero Dependencies - Pure vanilla JavaScript, no bloat

📦 Installation

npm install mayonation
# or
yarn add mayonation
# or
pnpm add mayonation

🚀 Getting Started

The core philosophy behind Mayonation is simplicity without sacrificing power. Here's how easy it is to create beautiful animations:

Your First Animation

import { mayo } from 'mayonation'

// Simple fade in
mayo({
  target: '.my-element',
  to: { opacity: 1, translateY: 0 },
  from: { opacity: 0, translateY: 20 },
  duration: 800,
  ease: 'easeOutCubic'
}).play()

Timeline Choreography

This is where Mayonation truly shines. Creating complex, synchronized animations:

import { timeline } from 'mayonation'

timeline()
  .add('.hero-title', { 
    to: { opacity: 1, translateY: 0 },
    from: { opacity: 0, translateY: 50 },
    duration: 1000 
  })
  .add('.hero-subtitle', { 
    to: { opacity: 1 },
    duration: 800 
  }, '+=200')  // Start 200ms after title
  .add('.hero-buttons', { 
    to: { opacity: 1, scale: 1 },
    from: { opacity: 0, scale: 0.8 },
    duration: 600,
    stagger: 100  // Animate each button 100ms apart
  }, '<+=400')  // Start 400ms after timeline begins
  .play()

SVG Path Magic

One of my favorite features - bringing SVG illustrations to life:

import { timeline } from 'mayonation'

// Draw and animate an SVG icon
timeline()
  .add('#icon-path', { 
    strokeDasharray: '0 100%',
    to: { strokeDasharray: '100% 0' },
    duration: 2000 
  })
  .add('#icon-fill', { 
    to: { opacity: 1 },
    duration: 500 
  }, '+=200')
  .play()

🎭 What You Can Build

Here are some real-world examples of what you can create:

🎬 Landing Page Hero Animations

// Orchestrate a complete hero section entrance
timeline()
  .add('.hero-bg', { to: { scale: 1.1 }, duration: 8000 })
  .add('.hero-title', { 
    to: { opacity: 1, rotateX: 0 },
    from: { opacity: 0, rotateX: -45 }
  }, 500)
  .add('.hero-subtitle', { to: { opacity: 1 } }, '+=300')
  .play()

🎨 Interactive Button Hovers

// Micro-interactions that feel alive
const button = mayo('.cta-button', {
  to: { scale: 1.05, boxShadow: '0 10px 25px rgba(0,0,0,0.3)' },
  duration: 200,
  ease: 'easeOutBack'
})

button.element.addEventListener('mouseenter', () => button.play())

📊 Data Visualization Reveals

// Animate charts and graphs
timeline()
  .add('.chart-bars', {
    to: { scaleY: 1 },
    from: { scaleY: 0 },
    duration: 1200,
    stagger: 100,
    ease: 'easeOutElastic'
  })
  .add('.chart-labels', { to: { opacity: 1 } }, '<+=800')
  .play()

🔧 Advanced Features I'm Proud Of

Intelligent Staggering

Animate multiple elements with sophisticated timing:

mayo('.grid-item', {
  to: { opacity: 1, translateY: 0 },
  from: { opacity: 0, translateY: 30 },
  stagger: {
    amount: 0.8, // Total stagger duration
    from: 'center', // Start from center outward
    grid: [4, 4] // 4x4 grid layout
  }
}).play()

Transform Origin Control

Perfect control over how elements transform:

mayo('.card', {
  to: { rotateY: 180 },
  transformOrigin: 'center right',
  duration: 800
}).play()

Color Space Interpolation

Smooth color transitions that actually look natural:

mayo('.element', {
  to: { backgroundColor: 'hsl(280, 100%, 50%)' },
  from: { backgroundColor: 'hsl(200, 100%, 50%)' },
  duration: 2000 // Animates through the shorter hue path
}).play()

🧠 The Technical Philosophy

Performance First

• GPU Acceleration: All transforms use translate3d, scale3d for hardware acceleration
• Minimal Reflows: Property updates are batched to prevent layout thrashing
• Smart Caching: Transform matrices are cached and only recalculated when needed
• Memory Efficient: Proper cleanup prevents memory leaks in long-running applications

Developer Experience

• IntelliSense Support: Full TypeScript definitions with helpful JSDoc
• Chainable API: Every method returns this for natural chaining
• Flexible Targeting: CSS selectors, DOM elements, NodeLists - it all works
• Comprehensive Events: Hook into every stage of the animation lifecycle

🤝 Contributing

I built this library because I believe in the power of community-driven development. Here's how you can get involved:

📊 Performance Benchmarks

I obsess over performance, so here are some numbers that matter:

Metric	Mayonation	GSAP	Anime.js	Framer Motion
Bundle Size (gzipped)	4.2kb	51kb	13.8kb	65kb+
Animation Start Time	<1ms	~2ms	~3ms	~5ms
Memory Usage	Low	Medium	Medium	High
TypeScript Support	Native	External	Partial	Good

Benchmarks run on Chrome 120, animating 100 elements

🔮 What's Next

This library is actively maintained and constantly evolving. Here's what I'm working on:

• 🎪 Spring Physics: Natural spring-based animations
• 🎬 Motion Path: Animate elements along custom SVG paths
• ⚡ Web Workers: Offload heavy calculations for even better performance
• 🎮 Gesture Integration: Touch and pointer event integration
• 🎨 Visual Timeline Editor: Browser extension for visual animation editing

🙏 Acknowledgments
