Using p5.js in Node - all "window" variables used by p5

These are the mandatory window properties accessed by p5.js on import, and what can be used instead:

window.requestAnimationFrame

By default, there is no requestAnimationFrame in node. p5 has a polyfill for requestAnimationFrame for older browsers, so we don't need to implement anything.

window.setTimeout = global.setTimeout

const w = 400, h = 400

setupWindow(w, h)
// import required even though the variable "p5" will not be used anywhere
const p5 = require("p5")

// Declare sketch variables here

function setup() {
  createCanvas(w, h);

dipamsen

const w = 400, h = 400
setupWindow(w, h)

const p5 = require("p5")

new p5(p => {
  // Declare sketch variables here
  p.setup = () => {
    p.createCanvas(w, h)
    // setup function

How to test directly:

1. download these files
2. npm install p5 canvas jsdom
3. node sketch.js <any-random-seed-here>
4. randomwalk will be saved as walk.png
