const source = ref('foo')
const { stop, pause, resume } = pausableWatch(
source,
(v) => console.log(`Changed to ${v}!`),
)
source.value = 'bar'
await nextTick() // Changed to bar!
pause()
source.value = 'foobar'
await nextTick() // (nothing happend)
resume()
source.value = 'hello'
await nextTick() // Changed to hello!
import { pausableWatch } from '@vueuse/core'
import { ref, nextTick } from 'vue'
const source = ref('foo')
const { stop, pause, resume } = pausableWatch(
source,
(v) => console.log(`Changed to ${v}!`),

source.value = 'bar'
await nextTick() // Changed to bar!
pause()
source.value = 'foobar'
await nextTick() // (nothing happend)
resume()
source.value = 'hello'
await nextTick() // Changed to hello!
