Requirements

• react >= 16.13.1
• react-dom >= 16.13.1

Usage

Using create-react-app's boiler-plate starter:

import * as React from 'react'
import logo from './logo.svg'
import './App.css'

import { ActiveBackground, Confetti } from '@exercism/react-active-background'

function App() {
  return (
    <div className="App">
      <header className="App-header">
        /*
         * Active Background must be the first child in a react container component
         */
        <ActiveBackground pattern={Confetti} />
        <img src={logo} className="App-logo" alt="logo" />
        <p>
          Edit <code>src/App.tsx</code> and save to reload.
        </p>
        <a
          className="App-link"
          href="https://reactjs.org"
          target="_blank"
          rel="noopener noreferrer"
        >
          Learn React
        </a>
      </header>
    </div>
  )
}

export default App

Extending with your own animation

You can extend the background with your own canvas based animation by creating a class which fulfills the following:

export interface IActiveBackgroundPatternConstructor {
  new (
    canvas: HTMLCanvasElement,
    options: ActiveBackgroundPatternOptions
  ): IActiveBackgroundPattern
}

export interface IActiveBackgroundPattern {
  render(): void
  start(): void
  stop(): void
}
