# Lottie Animations

## Overview

Lottie is a library for rendering After Effects animations in real-time on web, iOS, Android, and React Native. Created by Airbnb, it allows designers to ship animations as easily as shipping static assets. Animations are exported from After Effects as JSON files using the Bodymovin plugin, then rendered natively with minimal performance overhead.

**When to use Lottie:**
- Designer-created animations that need pixel-perfect fidelity
- Complex animated icons and micro-interactions
- Loading animations and progress indicators
- Onboarding sequences and tutorial animations
- Marketing animations and promotional content
- Alternative to GIF/video with smaller file sizes and scalability

**Key advantages:**
- Vector-based (scalable without quality loss)
- Significantly smaller file sizes than GIF or video
- Editable at runtime (colors, speed, segments)
- Full designer control via After Effects
- Cross-platform rendering consistency
- Interactive controls (play, pause, seek, loop)

## Core Concepts

### Lottie Format Types

**1. JSON Lottie (.json)**
- Original Lottie format
- Exported from After Effects via Bodymovin plugin
- Human-readable JSON structure
- Larger file sizes (not compressed)
- Widely supported across all platforms

**2. dotLottie (.lottie)**
- Modern compressed format
- ZIP archive containing JSON + assets
- Supports multiple animations and themes in one file
- Smaller file sizes (up to 90% reduction)
- Recommended for production use

### Library Options

**lottie-web** (original library):
```javascript
import lottie from 'lottie-web';

lottie.loadAnimation({
  container: document.getElementById('lottie-container'),
  renderer: 'svg', // or 'canvas', 'html'
  loop: true,
  autoplay: true,
  path: 'animation.json' // or animationData: jsonData
});
```

**@lottiefiles/dotlottie-web** (modern, recommended):
```javascript
import { DotLottie } from '@lottiefiles/dotlottie-web';

new DotLottie({
  canvas: document.getElementById('canvas'),
  src: 'animation.lottie',
  autoplay: true,
  loop: true
});
```

**@lottiefiles/dotlottie-react** (React integration):
```jsx
import { DotLottieReact } from '@lottiefiles/dotlottie-react';

<DotLottieReact
  src="animation.lottie"
  loop
  autoplay
  style={{ height: 300 }}
/>
```

**lottie-react** (alternative React wrapper):
```jsx
import Lottie from 'lottie-react';
import animationData from './animation.json';

<Lottie animationData={animationData} loop={true} />
```

### Animation Data Sources

**1. LottieFiles** (lottie.host)
- 100,000+ free animations
- Direct URL embedding
- CDN hosting

**2. Local JSON/dotLottie files**
- Bundled with application
- Better performance (no network request)
- Version control friendly

**3. After Effects export**
- Custom designer animations
- Bodymovin plugin required
- Export settings critical for file size

## Common Patterns

### 1. Basic HTML Integration with dotLottie-web

```html
<!DOCTYPE html>
<html>
<head>
  <style>
    #canvas {
      width: 400px;
      height: 400px;
    }
  </style>
</head>
<body>
  <canvas id="canvas"></canvas>

  <script type="module">
    import { DotLottie } from 'https://cdn.jsdelivr.net/npm/@lottiefiles/dotlottie-web/+esm';

    new DotLottie({
      canvas: document.getElementById('canvas'),
      src: 'https://lottie.host/4db68bbd-31f6-4cd8-84eb-189de081159a/IGmMCqhzpt.lottie',
      autoplay: true,
      loop: true
    });
  </script>
</body>
</html>
```
