useCountdown
Wrapper for useIntervalFn that provides a countdown timer.
Usage
import { useCountdown } from '@vueuse/core'
const countdownSeconds = 5
const { remaining, start, stop, pause, resume } = useCountdown(countdownSeconds, {
onComplete() {
},
onTick() {
}
})
You can use a ref to change the initial countdown.
start() and resume() also accept a new countdown value for the next countdown.
import { useCountdown } from '@vueuse/core'
import { shallowRef } from 'vue'
const countdown = shallowRef(5)
const { start, reset } = useCountdown(countdown, {
})
// change the countdown value
countdown.value = 10
// start a new countdown with 2 seconds
start(2)
// reset the countdown to 4, but do not start it
reset(4)
// start the countdown with the current value of `countdown`
start()
