# useCloned
|
|
|
|
Reactive clone of a ref. By default, it use `JSON.parse(JSON.stringify())` to do the clone.
|
|
|
|
## Usage
|
|
|
|
```ts
|
|
import { useCloned } from '@vueuse/core'
|
|
|
|
const original = ref({ key: 'value' })
|
|
|
|
const { cloned } = useCloned(original)
|
|
|
|
original.value.key = 'some new value'
|
|
|
|
console.log(cloned.value.key) // 'value'
|
|
```
|
|
|
|
## Manual cloning
|
|
|
|
```ts
|
|
import { useCloned } from '@vueuse/core'
|
|
|
|
const original = ref({ key: 'value' })
|
|
|
|
const { cloned, sync } = useCloned(original, { manual: true })
|
|
|
|
original.value.key = 'manual'
|
|
|
|
console.log(cloned.value.key) // 'value'
|
|
|
|
sync()
|
|
|
|
console.log(cloned.value.key)// 'manual'
|
|
```
|
|
|
|
## Custom Clone Function
|
|
|
|
Using [`klona`](https://www.npmjs.com/package/klona) for example:
|
|
|
|
```ts
|
|
import { useCloned } from '@vueuse/core'
|
|
import { klona } from 'klona'
|
|
|
|
const original = ref({ key: 'value' })
|
|
|
|
const { cloned, isModified, sync } = useCloned(original, { clone: klona })
|
|
```
|
|
|
|
## Type Declarations
|
|
|
|
```ts
|
|
export interface UseClonedOptions<T = any> extends WatchOptions {
|
|
/**
|
|
* Custom clone function.
|
|
*
|
|
* By default, it use `JSON.parse(JSON.stringify(value))` to clone.
|
|
*/
|
|
clone?: (source: T) => T
|
|
/**
|
|
* Manually sync the ref
|
|
*
|
|
* @default false
|
|
*/
|
|
manual?: boolean
|
|
}
|
|
export interface UseClonedReturn<T> {
|
|
/**
|
|
* Cloned ref
|
|
*/
|
|
cloned: Ref<T>
|
|
/**
|
|
* Ref indicates whether the cloned data is modified
|
|
*/
|
|
isModified: Ref<boolean>
|
|
/**
|
|
* Sync cloned data with source manually
|
|
*/
|
|
sync: () => void
|
|
}
|
|
export type CloneFn<F, T = F> = (x: F) => T
|
|
export declare function cloneFnJSON<T>(source: T): T
|
|
export declare function useCloned<T>(
|
|
source: MaybeRefOrGetter<T>,
|
|
options?: UseClonedOptions,
|
|
): UseClonedReturn<T>
|
|
```
