Connecting p5js and React js

P5DynamicLoader.js

// Uses dynamic component loading feature of nextjs
import dynamic from 'next/dynamic';
import sketch from './BGSketch'; // Sketch to load dynamically
import css from '../styles.less'

const P5DynamicLoader = dynamic(import('./P5Wrapper'), {
  ssr: false,
  loading: () => <div className={css.backgroundCanvas}>Loading Background...</div>,
});

export default () => <div className={css.backgroundCanvas}><P5DynamicLoader sketch = {sketch}/></div>

P5Wrapper.js

//requires p5 library from npm
import React, { Component } from 'react';
import p5 from 'p5';

export default class P5Wrapper extends React.Component {
  componentDidMount() {
    this.canvas = new p5(this.props.sketch, this.wrapper);
    if( this.canvas.myCustomRedrawAccordingToNewPropsHandler ) {
      this.canvas.myCustomRedrawAccordingToNewPropsHandler(this.props)
    }
  }

  componentWillReceiveProps(newprops) {
    if(this.props.sketch !== newprops.sketch){
      this.canvas.remove()
      this.canvas = new p5(newprops.sketch, this.wrapper)
    }
    if( this.canvas.myCustomRedrawAccordingToNewPropsHandler ) {
      this.canvas.myCustomRedrawAccordingToNewPropsHandler(newprops)
    }
  }

  componentWillUnmount() {
    this.canvas.remove()
  }

  render() {
    return <div ref={wrapper => this.wrapper = wrapper}></div>
  }
}
