ChelseaJS is a Javascript library for creative, generative Coding.

It's simple and intuitive syntax makes it easy for everyone (including non-coders) to get fimiliar with the library and start creating beautiful illustrations and learn in the process.

ChelseaJS is completely free and open source.

ChelseaJS provides you with a wide functionality for drawing and composition.

ChelseaJS is ever evolving and we are always looking for new features and improvements.

Using ChelseaJS

Load the built file with a plain script tag — it works from file:// too — and opt in to the bare-global sketch API:

<script src="https://beetrandahiya.github.io/ChelseaJS/chelsea.min.js"></script>
<script>
    Chelsea.install();   // gives sketches setCanvas(), new circle(...), WIDTH, ...

    elem = document.getElementById("container");
    setCanvas(elem);
    new circle(100, 100, 50, "#695fe6", 1, "#fff", 1);
</script>

A page that needs ChelseaJS together with Chelsea3D can skip install() and use the namespaced API directly: Chelsea.circle, Chelsea.setCanvas, ...

This repo ships built output only

chelsea.js and chelsea.min.js are generated from project-Chelsea/src/ by its build.js. Nothing here is hand-edited — source changes, sketches and issues about library internals belong in that repo. Browse the sketch gallery to see the library in action.

The implicit-function plotter that used to live here as test2.js (marching squares + quadtree) was not a library test; it now lives at project-Chelsea/sketches/implicit_plotter.js.
