Neos(奈欧斯)是一个帮助开发者快速地创建 Vue3 应用并自动配置项目编译的脚手架

import { tryOnMounted, tryOnUnmounted, useDebounceFn } from '@vueuse/core'

interface WindowSizeOptions {
  once?: boolean
  immediate?: boolean
  listenerOptions?: AddEventListenerOptions | boolean
}
interface Fn<T = any, R = T> {
  (...arg: T[]): R
}

export function useWindowSizeFn<T>(fn: Fn<T>, wait = 150, options?: WindowSizeOptions) {
  let handler = () => {
    fn()
  }
  const handleSize = useDebounceFn(handler, wait)
  handler = handleSize

  const start = () => {
    if (options && options.immediate)
      handler()

    window.addEventListener('resize', handler)
  }

  const stop = () => {
    window.removeEventListener('resize', handler)
  }

  tryOnMounted(() => {
    start()
  })

  tryOnUnmounted(() => {
    stop()
  })
  return [start, stop]
}
