watch with additional EventFilter control.

Usage

Similar to watch, but offering an extra option eventFilter which will be applied to the callback function.

ts
import { debounceFilter, watchWithFilter } from '@vueuse/core'

watchWithFilter(
  source,
  () => { console.log('changed!') }, // callback will be called in 500ms debounced manner
  {
    eventFilter: debounceFilter(500), // throttledFilter, pausabledFilter or custom filters
  },
)
import { debounceFilter, watchWithFilter } from '@vueuse/core'

watchWithFilter(
  source,
  () => { console.log('changed!') }, // callback will be called in 500ms debounced manner
  {
    eventFilter: debounceFilter(500), // throttledFilter, pausabledFilter or custom filters
  },
)
