# computedWithControl
|
|
|
|
Explicitly define the dependencies of computed.
|
|
|
|
## Usage
|
|
|
|
```ts twoslash include main
|
|
import { computedWithControl } from '@vueuse/core'
|
|
|
|
const source = ref('foo')
|
|
const counter = ref(0)
|
|
|
|
const computedRef = computedWithControl(
|
|
() => source.value, // watch source, same as `watch`
|
|
() => counter.value, // computed getter, same as `computed`
|
|
)
|
|
```
|
|
|
|
With this, the changes of `counter` won't trigger `computedRef` to update but the `source` ref does.
|
|
|
|
```ts
|
|
// @include: main
|
|
// ---cut---
|
|
console.log(computedRef.value) // 0
|
|
|
|
counter.value += 1
|
|
|
|
console.log(computedRef.value) // 0
|
|
|
|
source.value = 'bar'
|
|
|
|
console.log(computedRef.value) // 1
|
|
```
|
|
|
|
### Manual Triggering
|
|
|
|
You can also manually trigger the update of the computed by:
|
|
|
|
```ts
|
|
// @include: main
|
|
// ---cut---
|
|
const computedRef = computedWithControl(
|
|
() => source.value,
|
|
() => counter.value,
|
|
)
|
|
|
|
computedRef.trigger()
|
|
```
|
|
|
|
### Deep Watch
|
|
|
|
Unlike `computed`, `computedWithControl` is shallow by default.
|
|
You can specify the same options as `watch` to control the behavior:
|
|
|
|
```ts
|
|
const source = ref({ name: 'foo' })
|
|
|
|
const computedRef = computedWithControl(
|
|
source,
|
|
() => counter.value,
|
|
{ deep: true },
|
|
)
|
|
```
|
|
|
|
## Type Declarations
|
|
|
|
```ts
|
|
export interface ComputedWithControlRefExtra {
|
|
/**
|
|
* Force update the computed value.
|
|
*/
|
|
trigger: () => void
|
|
}
|
|
export interface ComputedRefWithControl<T>
|
|
extends ComputedRef<T>,
|
|
ComputedWithControlRefExtra {}
|
|
export interface WritableComputedRefWithControl<T>
|
|
extends WritableComputedRef<T>,
|
|
ComputedWithControlRefExtra {}
|
|
export type ComputedWithControlRef<T = any> =
|
|
| ComputedRefWithControl<T>
|
|
| WritableComputedRefWithControl<T>
|
|
export declare function computedWithControl<T>(
|
|
source: WatchSource | MultiWatchSources,
|
|
fn: ComputedGetter<T>,
|
|
options?: WatchOptions,
|
|
): ComputedRefWithControl<T>
|
|
export declare function computedWithControl<T>(
|
|
source: WatchSource | MultiWatchSources,
|
|
fn: WritableComputedOptions<T>,
|
|
options?: WatchOptions,
|
|
): WritableComputedRefWithControl<T>
|
|
/** @deprecated use `computedWithControl` instead */
|
|
export declare const controlledComputed: typeof computedWithControl
|
|
```
