直接上代码：

const option = {
  fpsLimit: 60,
  fullScreen: {
    enable: false /* 局部显示粒子效果 */
  },
  particles: {
    links: {
      enable: true,
      distance: 100
    },
    move: {
      enable: true,
      speed: 2,
      outModes: {
        default: 'bounce'
      }
    },
    size: {
      value: 1
    },
    number: {
      value: 30
    }
  }
}
