用于观察值并设置 {immediate: true} 的简写

用法

类似于 watch，但带有 { immediate: true }

import { watchImmediate
 } from '@vueuse/core'

const obj
 = ref
('vue-use')

// changing the value from some external store/composables
obj
.value
 = 'VueUse'

watchImmediate
(obj
, (updated
) => {
  console
.log
(updated
) // Console.log will be logged twice
})

类型声明

export declare function watchImmediate
<
  T
 extends Readonly
<WatchSource
<unknown>[]>,
>(
  source
: [...T
],
  cb
: WatchCallback
<MapSources
<T
>, MapOldSources
<T
, true>>,
  options
?: Omit
<WatchOptions
<true>, "immediate">,
): WatchHandle

export declare function watchImmediate
<T
>(
  source
: WatchSource
<T
>,
  cb
: WatchCallback
<T
, T
 | undefined>,
  options
?: Omit
<WatchOptions
<true>, "immediate">,
): WatchHandle

export declare function watchImmediate
<T
 extends object>(
  source
: T
,
  cb
: WatchCallback
<T
, T
 | undefined>,
  options
?: Omit
<WatchOptions
<true>, "immediate">,
