PixiJS — The HTML5 Creation Engine

pixi.js logo

Discord npm version Node.js CI

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.

If you want to keep up to date with the latest PixiJS news then feel free to follow us on Twitter @PixiJS and we will keep you posted! You can also check back on our site as any breakthroughs will be posted up there too!

We are now a part of the Open Collective and with your support you can help us make PixiJS even better. To make a donation, simply click the button below and we'll love you forever!

What to Use PixiJS for and When to Use It

PixiJS is a rendering library that will allow you to create rich, interactive graphics, cross-platform applications, and games without having to dive into the WebGL API or deal with browser and device compatibility.

PixiJS has full WebGL support and seamlessly falls back to HTML5's canvas if needed. As a framework, PixiJS is a fantastic tool for authoring interactive content, especially with the move away from Adobe Flash in recent years. 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 have 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!

Setup

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.

Note: After v4.5.0, support for the Bower package manager has been dropped. Please see the release notes for more information.

NPM Install

npm install pixi.js

There is no default export. The correct way to import PixiJS is:

import * as PIXI from 'pixi.js';

CDN Install

Via jsDelivr:

<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/pixi.min.js"></script>

Or via unpkg:

<script src="https://unpkg.com/[email protected]/dist/pixi.min.js"></script>

Demos

Thanks to @photonstorm for providing those last 2 examples and allowing us to share the source code :)

Basic Usage Example

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();

// The application will create a canvas element for you that you
// can then insert into the DOM
document.body.appendChild(app.view);

// 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;
});

How to build

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

Error installing gl package

In most cases installing gl from npm should just work. However, if you run into problems you might need to adjust your system configuration and make sure all your dependencies are up to date

Please refer to the gl installation guide for more information.

Error installing canvas package

The canvas library currently being used does not have a pre-built version for every environment. When the package detects an unsupported environment, it will try to build from source.

To build from source you will need to make sure you have the following dependencies installed and then reinstall:

brew install pkg-config cairo pango libpng jpeg giflib librsvg

For non-mac users, please refer to the canvas installation guide for more information.

How to generate the documentation

The docs can be generated using npm:

npm run docs

The documentation uses webdoc in combination with this template pixi-webdoc-template. The configuration file can be found at webdoc.conf.json
