How to use react with p5.js?

@hal.littel 

To use React with p5.js, you can create a component in React that includes the p5.js library to render graphics and animations. Here's how you can integrate p5.js with React:

1. Install p5.js library: Include the p5.js library in your React project. You can do this by installing it via npm or including it in your HTML file.
2. Create a p5 sketch component: Create a new component in your React project that will be used to render the p5 sketch. You can use a class-based component or a functional component with hooks.
3. Initialize p5 sketch: In your component, use the useEffect hook to initialize the p5 sketch. Inside the useEffect function, create an instance of p5 and define your sketch functions (such as setup and draw).

Here's an example of how you can create a p5 sketch component in React:

import React, { useEffect } from 'react';

const Sketch = () => {
  useEffect(() => {
    const sketch = new p5(p => {
      p.setup = () => {
        p.createCanvas(400, 400);
        p.background(255);
      }

      p.draw = () => {
        p.ellipse(p.mouseX, p.mouseY, 50, 50);
      }
    });
  }, []);

  return (
    <div></div>
  );
}

export default Sketch;

1. Render the sketch component: Include your p5 sketch component in your React app and render it wherever you want to display the p5 graphics.
2. Customize and interact with the sketch: You can customize your p5 sketch by adding additional functions, event listeners, or interactions within the p5 sketch component. You can also pass props to the component to dynamically update the sketch based on user input or data changes.

By following these steps, you can easily integrate p5.js with React to create interactive and dynamic visualizations in your web applications.
