This is one way to use p5.js with TypeScript and Express.

## Usage

The following will use Express to serve the `public` directory and watch for changes to `src`.

```bash

npm i

npm run start

```

To format all files, run `npm run pretty`.  

See other scripts in [package.json](package.json).

### Singleton

This project uses a singleton design pattern to share the p5 object across files. It can be used like so.

First set up the static object:

```ts

import { P5Singleton } from "@/utilities/p5-singleton";

import { Sketch } from "types/sketch"; // optional

const sketch = (p: p5) => {

  P5Singleton.setInstance(p as Sketch);

  p.setup = setup;

  p.draw = draw;

};

new p5(sketch);

```

Then you can retrieve it with `getInstance` as needed:

```ts

// setup.ts

export const setup = () => {

  const p = P5Singleton.getInstance();

  p.createCanvas(...computeSize());

}

```
