More Animation and Effects Libraries

While GSAP and Framer Motion are the most popular choices, there are many other excellent animation libraries worth considering. Each has unique strengths and use cases.

1. Anime.js

Anime.js is a lightweight JavaScript animation library with a simple yet powerful API.

Overview

• Size: ~17KB minified
• Framework: Framework-agnostic
• License: MIT (Free)
• Best For: Lightweight animations, SVG animations, timeline sequences

Key Features

• Lightweight: One of the smallest full-featured animation libraries
• Simple API: Easy to learn and use
• CSS, SVG, DOM, and JS object animations: Animate anything
• Built-in callbacks and controls: Timeline control similar to GSAP
• No dependencies: Pure JavaScript

Installation

npm install animejs

Basic Usage

import anime from 'animejs';

// Simple animation
anime({
  targets: '.box',
  translateX: 250,
  rotate: '1turn',
  backgroundColor: '#FFF',
  duration: 800,
  easing: 'easeInOutQuad'
});

Timeline Example

const timeline = anime.timeline({
  easing: 'easeOutExpo',
  duration: 750
});

timeline
  .add({
    targets: '.box1',
    translateX: 250
  })
  .add({
    targets: '.box2',
    translateY: 250
  }, '-=600') // start 600ms before previous animation ends
  .add({
    targets: '.box3',
    rotate: 180
  });

Stagger Animation

anime({
  targets: '.stagger-box',
  translateX: 270,
  delay: anime.stagger(100) // increase delay by 100ms for each element
});

SVG Path Animation

anime({
  targets: 'path',
  strokeDashoffset: [anime.setDashoffset, 0],
  easing: 'easeInOutSine',
  duration: 1500,
  direction: 'alternate',
  loop: true
});

    config: { mass: 5, tension: 500, friction: 80 },
  });
  
  return (
    <animated.div
      onClick={() => setIsFlipped(!isFlipped)}
      style={{ opacity, transform }}
    >
      Content
    </animated.div>
  );
}

    <animated.div style={style}>{item.text}</animated.div>
  ));
}

Trail (Stagger) Animation

import { useTrail, animated } from '@react-spring/web';
