I have done

npm install p5 --save

I edited the .angular.cli.json

"scripts": [
    "../node_modules/p5/lib/p5.min.js",   
    "../node_modules/p5/lib/addons/p5.sound.js",   
    "../node_modules/p5/lib/addons/p5.dom.js" 
  ]

and imported as

import * as p5 from 'p5';

in app.component.ts file

but now where to add the function setup() and function draw() . I have tried adding it directly but it doesn't work

That's the way you import it that causes the problem. You should import it by typing:

import 'p5';

Then declare a variable:

private p5;

You should now be able to do something like this:

ngOnInit() {
  this.createCanvas();
}

private createCanvas() {
  this.p5 = new p5(this.sketch);
}

private sketch(p: any) {
  p.setup = () => {
    p.createCanvas(700, 600);
  };

  p.draw = () => {
    p.background(255);
    p.fill(0);
    p.rect(p.width / 2, p.height / 2, 50, 50);
  };
}

Here's my ng version :

Angular CLI: 1.7.4
Node: 9.11.1
OS: win32 x64
Angular: 5.2.11
... animations, common, compiler, compiler-cli, core, forms

@schematics/angular: 0.3.2
@schematics/package-update: 0.3.2
typescript: 2.5.3
webpack: 3.11.0

and last version of p5 in package.json:

 "p5": "^0.6.1"

Everything's working fine for me.

Hope it will help.

Found a GitHub repo with examples that show how to import and implement. It helped fill in what I was missing, how to actually display the canvas.

In the template HTML add a div with an ID.

<div id="analog-clock-canvas"></div>

Then in your component when you create the canvas you can attach it to this div.

private drawing = function (p: any) {
p.setup = () => {
  p.createCanvas(p.windowWidth, p.windowHeight).parent('analog-clock-canvas');
  p.angleMode(p.DEGREES);
  p.rectMode(p.CENTER);
  p.background(0);
};
p.center = { x: 0, y: 0 };
p.draw = () => {

  • maybe they are in the p5 namespace, since you imported * as p5?
  • @BrendanWhiting are you saying something like p5.setup();
  • Yes, try that. You could also try import * from 'p5'
  • Actually it is searching for a p5.d.ts file which is not available what should i do
  • Not sure if it exists. There seems to be a discussion about it: github.com/processing/p5.js/issues/583. But you shouldn't have to have the type definitions to use the library. I dunno.
  • thanks for the answer and the link!
