响应式的相对时间。当时间发生变化时,自动更新相对时间字符串。

示例

just now
0ms

用法

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

const timeAgo = useTimeAgo(new Date(2021, 0, 1))

组件用法

vue
<template>
  <UseTimeAgo v-slot="{ timeAgo }" :time="new Date(2021, 0, 1)">
    Time Ago: {{ timeAgo }}
  </UseTimeAgo>
</template>

非响应式用法

如果你不需要响应性,可以使用 formatTimeAgo 函数获取格式化的字符串,而不是一个 Ref。

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

const timeAgo = formatTimeAgo(new Date(2021, 0, 1)) // 字符串
