# useMounted
|
|
|
|
Mounted state in ref.
|
|
|
|
## Usage
|
|
|
|
```ts
|
|
import { useMounted } from '@vueuse/core'
|
|
|
|
const isMounted = useMounted()
|
|
```
|
|
|
|
Which is essentially a shorthand of:
|
|
|
|
```ts
|
|
const isMounted = ref(false)
|
|
|
|
onMounted(() => {
|
|
isMounted.value = true
|
|
})
|
|
```
|
|
|
|
## Type Declarations
|
|
|
|
```ts
|
|
/**
|
|
* Mounted state in ref.
|
|
*
|
|
* @see https://vueuse.org/useMounted
|
|
*
|
|
* @__NO_SIDE_EFFECTS__
|
|
*/
|
|
export declare function useMounted(): ShallowRef<boolean, boolean>
|
|
```
