q5.js is a spiritual successor to the p5.js and Processing Java graphics libraries.

The q5 team aims to make creative coding even more fun and accessible for a new generation of artists, designers, educators, and beginners!

If you're already familiar with p5, you'll find yourself right at home with q5. It's also compatible with popular addons, including p5.sound and p5play.

No Installation Required

Try out the q5.js template sketch for the Aijs online code editor.

Use q5.js in your own project by adding this line to your HTML file:

<script src="https://q5js.org/q5.js"></script>

q5 is also available on npm!

npm install q5

Using p5 Addon Libraries

q5 is compatible with popular p5 addons and projects that use p5, such as p5play, because it aliases Q5 to p5.

To use addons, simply load them after q5.js:

<script src="https://q5js.org/q5.js"></script>
<!-- load p5 addons after q5 -->
<script src="https://p5play.org/v3/planck.min.js"></script>
<script src="https://p5play.org/v3/p5play.js"></script>

Documentation

Browse the q5 reference pages to learn how to use q5.js.

See the wiki for extended documentation of q5's exclusive features.

Use the q5.d.ts file in Visual Studio Code to get autocompletion and inline hover-over documentation. Simply add this jsconfig.json file to your project folder:

{
	"compilerOptions": {
		"target": "ESNext"
	},
	"include": ["*.js", "**/*.js", "node_modules/q5/q5.d.ts"]
}

Support this project 🤝

q5 is open source and anyone can use it for free under the terms of the LGPL (just like p5.js). 🎉

We need your support though! If you enjoy using q5.js, please donate via GitHub Sponsors or Patreon.

Modular Use

p5.js is nearly 5MB in size. This is mainly due to lengthy JSDoc comments, the WebGL render, and the dependencies corejs and opentype. If 2d rendering is all a sketch needs, p5 wastes user bandwidth and is slower to load, parse, and run.

q5.js (the default bundle) is 98% smaller than p5, which is already great for typical use. For extremely lightweight use you can load a subset of scripts from the src folder.

See the src/readme.md for more info on modular use.
