Examples

Learn how to use the Timer component in your project. Let's take a look at the most basic example:

import { Timer } from '@ark-ui/react'

export const Basic = () => (
  <Timer.Root targetMs={60 * 60 * 1000}>
    <Timer.Area>
      <Timer.Item type="days" />
      <Timer.Separator>:</Timer.Separator>
      <Timer.Item type="hours" />
      <Timer.Separator>:</Timer.Separator>
      <Timer.Item type="minutes" />
      <Timer.Separator>:</Timer.Separator>
      <Timer.Item type="seconds" />
    </Timer.Area>
    <Timer.Control>
      <Timer.ActionTrigger action="start">Play</Timer.ActionTrigger>
      <Timer.ActionTrigger action="resume">Resume</Timer.ActionTrigger>
      <Timer.ActionTrigger action="pause">Pause</Timer.ActionTrigger>
    </Timer.Control>
  </Timer.Root>
)

import { Timer } from '@ark-ui/solid'

export const Basic = () => (
  <Timer.Root targetMs={60 * 60 * 1000}>
    <Timer.Area>
      <Timer.Item type="days" />
      <Timer.Separator>:</Timer.Separator>
      <Timer.Item type="hours" />
      <Timer.Separator>:</Timer.Separator>
      <Timer.Item type="minutes" />
      <Timer.Separator>:</Timer.Separator>
      <Timer.Item type="seconds" />
    </Timer.Area>
    <Timer.Control>
      <Timer.ActionTrigger action="start">Play</Timer.ActionTrigger>
      <Timer.ActionTrigger action="resume">Resume</Timer.ActionTrigger>
      <Timer.ActionTrigger action="pause">Pause</Timer.ActionTrigger>
    </Timer.Control>
  </Timer.Root>
)

<script setup lang="ts">
import { Timer } from '@ark-ui/vue'
</script>

<template>
  <Timer.Root :targetMs="60 * 60 * 1000">
    <Timer.Area>
      <Timer.Item type="days" />
      <Timer.Separator>:</Timer.Separator>
      <Timer.Item type="hours" />
      <Timer.Separator>:</Timer.Separator>
      <Timer.Item type="minutes" />
      <Timer.Separator>:</Timer.Separator>
      <Timer.Item type="seconds" />
    </Timer.Area>
    <Timer.Control>
      <Timer.ActionTrigger action="start">Play</Timer.ActionTrigger>
      <Timer.ActionTrigger action="resume">Resume</Timer.ActionTrigger>
      <Timer.ActionTrigger action="pause">Pause</Timer.ActionTrigger>
    </Timer.Control>
  </Timer.Root>
</template>

Countdown Timer

You can create a countdown timer by setting the targetMs prop to a future timestamp:

import { Timer } from '@ark-ui/react'

export const Countdown = () => (
  <Timer.Root autoStart countdown startMs={60 * 60 * 500}>
    <Timer.Area>
      <Timer.Item type="days" />
      <Timer.Separator>:</Timer.Separator>
      <Timer.Item type="hours" />
      <Timer.Separator>:</Timer.Separator>
      <Timer.Item type="minutes" />
      <Timer.Separator>:</Timer.Separator>
      <Timer.Item type="seconds" />
    </Timer.Area>
  </Timer.Root>
)

import { Timer } from '@ark-ui/solid'

export const Countdown = () => (
  <Timer.Root autoStart countdown startMs={60 * 60 * 500}>
    <Timer.Area>
      <Timer.Item type="days" />
      <Timer.Separator>:</Timer.Separator>
      <Timer.Item type="hours" />
      <Timer.Separator>:</Timer.Separator>
      <Timer.Item type="minutes" />
      <Timer.Separator>:</Timer.Separator>
      <Timer.Item type="seconds" />
    </Timer.Area>
  </Timer.Root>
)

<script setup lang="ts">
import { Timer } from '@ark-ui/vue'
</script>

<template>
  <Timer.Root :autoStart="true" :countdown="true" :startMs="60 * 60 * 500">
    <Timer.Area>
      <Timer.Item type="days" />
      <Timer.Separator>:</Timer.Separator>
      <Timer.Item type="hours" />
      <Timer.Separator>:</Timer.Separator>
      <Timer.Item type="minutes" />
      <Timer.Separator>:</Timer.Separator>
      <Timer.Item type="seconds" />
    </Timer.Area>
  </Timer.Root>
</template>

Timer Events

The Timer component provides events that you can listen to for various timer-related actions.

The onComplete event is triggered when the timer reaches its target time.
The onTick event is called on each timer update, providing details about the current timer state.

import { Timer } from '@ark-ui/react'

export const Events = () => (
  <Timer.Root
    targetMs={5 * 1000}
    onComplete={() => console.log('Timer completed')}
    onTick={(details) => console.log('Tick:', details.formattedTime)}
  >
    <Timer.Item type="seconds" />
  </Timer.Root>
)

import { Timer } from '@ark-ui/solid'

export const Events = () => (
  <Timer.Root
    targetMs={5 * 1000}
    onComplete={() => console.log('Timer completed')}
    onTick={(details) => console.log('Tick:', details.formattedTime)}
  >
    <Timer.Item type="seconds" />
  </Timer.Root>
)

<script setup lang="ts">
import { Timer } from '@ark-ui/vue'
</script>

<template>
  <Timer.Root
    :targetMs="5 * 1000"
    @complete="() => console.log('Timer completed')"
    @tick="(details) => console.log('Tick:', details.formattedTime)"
  >
    <Timer.Item type="seconds" />
  </Timer.Root>
</template>
