Watch

watchOnce

Shorthand for watching value with { once: true }. Once the callback fires once, the watcher will be stopped. See Vue's docs for full details.

Usage

Similar to watch, but with { once: true }

import { watchOnce } from '@vueuse/core'

watchOnce(source, () => {
  // triggers only once
  console.log('source changed!')
})

Type Declarations

export declare function watchOnce<T extends Readonly<MultiWatchSources>>(
  source: [...T],
  cb: WatchCallback<MapSources<T>, MapOldSources<T, true>>,
  options?: Omit<WatchOptions<true>, "once">,
): WatchHandle
export declare function watchOnce<T>(
  source: WatchSource<T>,
  cb: WatchCallback<T, T | undefined>,
  options?: Omit<WatchOptions<true>, "once">,
): WatchHandle
export declare function watchOnce<T extends object>(
  source: T,
  cb: WatchCallback<T, T | undefined>,
  options?: Omit<WatchOptions<true>, "once">,
): WatchHandle
