animejs

What is animejs?

Anime.js is a lightweight JavaScript animation library with a simple, yet powerful API. It works with CSS properties, SVG, DOM attributes, and JavaScript Objects.

What are animejs's main functionalities?

Basic Animation

This feature allows you to animate basic properties like translation, rotation, and background color of a DOM element.

anime({
  targets: 'div',
  translateX: 250,
  rotate: '1turn',
  backgroundColor: '#FFF',
  duration: 800
});

Timeline Control

Timelines allow you to create complex animation sequences with precise control over the timing of each animation.

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

tl.add({
  targets: '.box',
  translateX: 250
}).add({
  targets: '.box',
  translateY: 250,
  offset: '-=500' // Starts 500ms before the previous animation ends
});

SVG Animations

Anime.js can animate SVG properties, allowing for intricate and visually appealing vector animations.

anime({
  targets: 'path',
  strokeDashoffset: [anime.setDashoffset, 0],
  easing: 'easeInOutSine',
  duration: 1500,
  delay: function(el, i) { return i * 250 },
  direction: 'alternate',
  loop: true
});

Keyframes

Keyframes allow you to define multiple stages of an animation, giving you more control over the animation sequence.

anime({
  targets: '.box',
  keyframes: [
    {translateX: 250},
    {translateY: 250},
    {translateX: 0},
    {translateY: 0}
  ],
  duration: 4000,
  easing: 'easeOutElastic(1, .8)',
  loop: true
});
