useIdle

Demo

For demonstration purpose, the idle timeout is set to 5s in this demo (default 1min).

Idle: false

Inactive: 0s

Usage

import { useIdle } from '@vueuse/core'

const { idle, lastActive } = useIdle(5 * 60 * 1000) // 5 min

console.log(idle.value) // true or false

Programatically resetting:

import { watch } from 'vue'
import { useCounter, useIdle } from '@vueuse/core'

const { inc, count } = useCounter()

const { idle, lastActive, reset } = useIdle(5 * 60 * 1000) // 5 min

watch(idle, (idleValue) => {
  if (idleValue) {
    inc()
    console.log(`Triggered ${count.value} times`)
    reset() // restarts the idle timer. Does not change lastActive value
  }
})

Component Usage

This function also provides a renderless component version via the @vueuse/components package. Learn more about the usage.
