useStopwatch - Demo

Example

<template>
    <div>
        <h1>vue-timer-hook </h1>
        <p>Stopwatch Demo</p>
        <div>
            <span>{{stopwatch.days}}</span>:<span>{{stopwatch.hours}}</span>:<span>{{stopwatch.minutes}}</span>:<span>{{stopwatch.seconds}}</span>
        </div>
        <p>{{stopwatch.isRunning ? 'Running' : 'Not running'}}</p>
        <button @click="stopwatch.start()">Start</button>
        <button @click="stopwatch.pause()">Pause</button>
        <button @click="stopwatch.reset()">Reset</button>
    </div>
</template>


<script setup lang="ts">
import { defineComponent } from "vue";
import { useStopwatch } from 'vue-timer-hook';

const autoStart = true;
const stopwatch = useStopwatch(autoStart);
</script>

Settings

key	Type	Required	Description
autoStart	boolean	No	if set to true stopwatch will auto start, by default it is set to false
offsetTimestamp	number	No	this will define the initial stopwatch offset example: const stopwatchOffset = new Date(); stopwatchOffset.setSeconds(stopwatchOffset.getSeconds() + 300); this will result in a 5 minutes offset and stopwatch will start from 0:0:5:0 instead of 0:0:0:0

Values

key	Type	Description
seconds	number	seconds value
minutes	number	minutes value
hours	number	hours value
days	number	days value
isRunning	boolean	flag to indicate if stopwatch is running or not
start	function	function to be called to start/resume stopwatch
pause	function	function to be called to pause stopwatch
reset	function	function to be called to reset stopwatch to 0:0:0:0, you can also pass offset parameter to this function to reset stopwatch with offset, similar to how offsetTimestamp will offset the initial stopwatch time, this function will accept also a second argument which will decide if stopwatch should automatically start after reset or not default is true
