// (options are optional, defaults defined below)
const container = document.getElementById('container')
const options = {
  maxRockets: 3, // max # of rockets to spawn
  rocketSpawnInterval: 150, // millisends to check if new rockets should spawn
  numParticles: 100, // number of particles to spawn when rocket explodes (+0-10)
  explosionMinHeight: 0.2, // percentage. min height at which rockets can explode
  explosionMaxHeight: 0.9, // percentage. max height before a particle is exploded
  explosionChance: 0.08, // chance in each tick the rocket will explode
  width: container.clientWidth, // override the width, defaults to container width
  height: container.clientHeight // override the height, defaults to container height
}

// instantiate the class and call start
// this returns a disposable - calling it will stop fireworks.
const fireworks = new Fireworks(container, options)
const stop = fireworks.start()
stop() // stop rockets from spawning
fireworks.stop() // also stops fireworks.
fireworks.kill() // forcibly stop fireworks
fireworks.fire() // fire a single rocket.
fireworks.resetSize() // resets the size to the containers dimensions
fireworks.setSize(100, 100) // sets the size to the specified dimensions
fireworks.onFinish(() => container.remove()) // callback when the last firework disappears
