Throttle changing of a ref value.

Demo ​

Delay is set to 1000ms for this demo.

Throttled:

Times Updated: 0

Trailing: true

Leading: false

Usage ​

js
import { refThrottled } from '@vueuse/core'

const input = ref('')
const throttled = refThrottled(input, 1000)

Trailing ​

If you don't want to watch trailing changes, set 3rd param false (it's true by default):

js
import { refThrottled } from '@vueuse/core'

const input = ref('')
const throttled = refThrottled(input, 1000, false)

Leading ​

Allows the callback to be invoked immediately (on the leading edge of the ms timeout). If you don't want this behavior, set the 4th param false (it's true by default):

js
import { refThrottled } from '@vueuse/core'

const input = ref('')
const throttled = refThrottled(input, 1000, undefined, false)

Type Declarations ​

typescript
/**
 * Throttle execution of a function. Especially useful for rate limiting
 * execution of handlers on events like resize and scroll.
 *
 * @param value Ref value to be watched with throttle effect
 * @param  delay  A zero-or-greater delay in milliseconds. For event callbacks, values around 100 or 250 (or even higher) are most useful.
 * @param [trailing] if true, update the value again after the delay time is up
 * @param [leading] if true, update the value on the leading edge of the ms timeout
 */
export declare function refThrottled<T>(
  value: Ref<T>,
  delay?: number,
  trailing?: boolean,
  leading?: boolean,
): Ref<T>
export { refThrottled as useThrottle, refThrottled as throttledRef }
