# 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
```
