# useLastChanged
|
|
|
|
Records the timestamp of the last change
|
|
|
|
## Usage
|
|
|
|
```ts
|
|
import { useLastChanged } from '@vueuse/core'
|
|
import { nextTick } from 'vue'
|
|
|
|
const a = ref(0)
|
|
const lastChanged = useLastChanged(a)
|
|
|
|
a.value = 1
|
|
|
|
await nextTick()
|
|
|
|
console.log(lastChanged.value) // 1704709379457
|
|
```
|
|
|
|
By default the change is recorded on the next tick (`watch()` with `flush: 'post'`). If you want to record the change immediately, pass `flush: 'sync'` as the second argument.
|
|
|
|
```ts
|
|
import { useLastChanged } from '@vueuse/core'
|
|
|
|
const a = ref(0)
|
|
const lastChanged = useLastChanged(a, { flush: 'sync' })
|
|
|
|
a.value = 1
|
|
|
|
console.log(lastChanged.value) // 1704709379457
|
|
```
|
|
|
|
## Type Declarations
|
|
|
|
```ts
|
|
export interface UseLastChangedOptions<
|
|
Immediate extends boolean,
|
|
InitialValue extends number | null | undefined = undefined,
|
|
> extends WatchOptions<Immediate> {
|
|
initialValue?: InitialValue
|
|
}
|
|
export type UseLastChangedReturn =
|
|
| Readonly<ShallowRef<number | null>>
|
|
| Readonly<ShallowRef<number>>
