# useCached
|
|
|
|
Cache a ref with a custom comparator.
|
|
|
|
## Usage
|
|
|
|
```ts
|
|
import { useCached } from '@vueuse/core'
|
|
import { shallowRef } from 'vue'
|
|
|
|
interface Data {
|
|
value: number
|
|
extra: number
|
|
}
|
|
|
|
const source = shallowRef<Data>({ value: 42, extra: 0 })
|
|
const cached = useCached(source, (a, b) => a.value === b.value)
|
|
|
|
source.value = {
|
|
value: 42,
|
|
extra: 1,
|
|
}
|
|
|
|
console.log(cached.value) // { value: 42, extra: 0 }
|
|
|
|
source.value = {
|
|
value: 43,
|
|
extra: 1,
|
|
}
|
|
|
|
console.log(cached.value) // { value: 43, extra: 1 }
|
|
```
|
|
|
|
## Type Declarations
|
|
|
|
```ts
|
|
export interface UseCachedOptions<D extends boolean = true>
|
|
extends ConfigurableDeepRefs<D>,
|
|
WatchOptions {}
|
|
export declare function useCached<T, D extends boolean = true>(
|
|
refValue: Ref<T>,
|
|
comparator?: (a: T, b: T) => boolean,
|
|
options?: UseCachedOptions<D>,
|
|
): UseCachedReturn<T, D>
|
|
export type UseCachedReturn<
|
|
T = any,
|
|
D extends boolean = true,
|
|
> = ShallowOrDeepRef<T, D>
|
|
```
