Pixi.js is a fast 2D rendering engine that uses WebGL and HTML5 Canvas to create interactive graphics and animations. It is widely used for creating games, interactive applications, and other visual content on the web.
Creating a Basic Application
This code initializes a new Pixi.js application with a specified width and height, and appends the canvas element to the document body.
const app = new PIXI.Application({ width: 800, height: 600 });
document.body.appendChild(app.view);Loading and Displaying a Sprite
This code loads an image and creates a sprite from it. The sprite is then positioned at the center of the canvas and added to the stage.
PIXI.Loader.shared.add('bunny', 'path/to/bunny.png').load((loader, resources) => {
const bunny = new PIXI.Sprite(resources.bunny.texture);
bunny.x = app.renderer.width / 2;
bunny.y = app.renderer.height / 2;
bunny.anchor.set(0.5);
app.stage.addChild(bunny);
});Animating a Sprite
This code adds an animation loop that rotates the sprite continuously. The `delta` parameter ensures smooth animation regardless of the frame rate.
app.ticker.add((delta) => {
bunny.rotation += 0.1 * delta;
});Creating Graphics
This code creates a new graphics object, draws a filled rectangle, and adds it to the stage.
const graphics = new PIXI.Graphics();
graphics.beginFill(0xDE3249);
graphics.drawRect(50, 50, 100, 100);
graphics.endFill();
app.stage.addChild(graphics);Three.js is a popular 3D library that provides a wide range of features for creating 3D graphics and animations. While Pixi.js focuses on 2D rendering, Three.js is more suitable for complex 3D scenes and visualizations.
Phaser is a fast, robust, and versatile game framework that supports both 2D and 3D rendering. It is more game-oriented compared to Pixi.js, offering built-in physics, input handling, and other game development features.
Konva is a 2D canvas library that provides a high-level API for creating complex shapes, animations, and interactions. It is similar to Pixi.js but focuses more on ease of use and simplicity for creating interactive graphics.
This project aims to provide a fast, lightweight 2D library that works across all devices. The PixiJS renderer allows everyone to enjoy the power of hardware acceleration without prior knowledge of WebGL. Also, it's fast. Really fast.

PixiJS is a rendering library that will allow you to create rich, interactive graphics and cross-platform applications and games without having to dive into the WebGL API or deal with browser and device compatibility.
PixiJS supports WebGPU with fallback support for WebGL. As a library, PixiJS is a fantastic tool for authoring interactive content. Use it for your graphics-rich, interactive websites, applications, and HTML5 games. Out-of-the-box, cross-platform compatibility and graceful degradation mean you have less work to do and more fun doing it! If you want to create polished and refined experiences relatively quickly without delving into dense, low-level code, all while avoiding the headaches of browser inconsistencies, then sprinkle your next project with some PixiJS magic!
Boost your development and feel free to use your imagination!
It's easy to get started with PixiJS! Simply download a prebuilt build!
Alternatively, PixiJS can be installed with npm or simply using a content delivery network (CDN) URL to embed PixiJS directly on your HTML page.
npm install pixi.js
There is no default export. The correct way to import PixiJS is:
import * as PIXI from 'pixi.js';
Via jsDelivr:
<script src="https://cdn.jsdelivr.net/npm/pixi.js@7.x/dist/pixi.min.js"></script>
Or via unpkg:
<script src="https://unpkg.com/pixi.js@7.x/dist/pixi.min.js"></script>
import { Application, Sprite, Assets } from 'pixi.js';
// The application will create a renderer using WebGL, if possible,
// with a fallback to a canvas render. It will also setup the ticker
// and the root stage PIXI.Container
const app = new Application();
// Wait for the Renderer to be available
await app.init();
// The application will create a canvas element for you that you
// can then insert into the DOM
document.body.appendChild(app.canvas);
// load the texture we need
const texture = await Assets.load('bunny.png');
// This creates a texture from a 'bunny.png' image
const bunny = new Sprite(texture);
// Setup the position of the bunny
bunny.x = app.renderer.width / 2;
bunny.y = app.renderer.height / 2;
// Rotate around the center
bunny.anchor.x = 0.5;
bunny.anchor.y = 0.5;
// Add the bunny to the scene we are building
app.stage.addChild(bunny);
// Listen for frame updates
app.ticker.add(() => {
// each frame we spin the bunny around a bit
bunny.rotation += 0.01;
});
Note that for most users you don't need to build this project. If all you want is to use PixiJS, then just download one of our prebuilt releases. The only time you should need to build PixiJS is if you are developing it.
If you don't already have Node.js and NPM, go install them. Then, in the folder where you have cloned the repository, install the build dependencies using npm:
npm install
Then, to build the source, run:
npm run build
The docs can be generated using npm:
npm run docs
