Spritejs is a cross platform high-performance graphics system, which can render graphics on web, node, desktop applications and mini-programs.

Spritejs^Next is the new version of spritejs. It is renderer agnostic enabling the same api to render in multiple contexts: webgl2, webgl, and canvas2d.

Manipulate the sprites in canvas as you do with the DOM elements.

Features

• Manipulate the sprites element as you do with the DOM elements.
• Rendering by WebGL2 context.
• Multiple layers.
• DOM Events.
• Object Oriented Programmed Development with ES6+.
• OffscreenCanvas and Web Worker.
• Work with d3.
• Server-side rendering.
• Vue.

Quick Start

SpriteJS - spritejs.com

<script src="https://unpkg.com/spritejs@3/dist/spritejs.min.js"></script>
<div id="container" style="width:400px;height:400px"></div>
<script>
    const imgUrl = 'https://s5.ssl.qhres2.com/static/ec9f373a383d7664.svg'
    const {Scene, Sprite} = spritejs;
    const container = document.getElementById('container');
    const paper = new Scene({
      container,
      width: 400,
      height: 400,
    })

    const sprite = new Sprite(imgUrl)
    sprite.attr({
      bgcolor: '#fff',
      pos: [0, 0],
      size: [400, 400],
