Features

⛰ Nuxt 3 ready
🚠 Activate any plugin or locale available
🌲 Specify default locales and timezones

Quick Setup

Add dayjs-nuxt dependency to your project

npx nuxi@latest module add dayjs

Add dayjs-nuxt to the modules section of nuxt.config.ts

export default defineNuxtConfig({
  modules: [
    'dayjs-nuxt'
  ]
})

Basic Usage

You can use the provided $dayjs to access Day.js in template.

<template>
  <div>
    <time :datetime="$dayjs('2023-01-01').utc().toString()"> {{ date }} </time>
  </div>
</template>

Composables

You can use the useDayjs composable to access Day.js anywhere.

<script setup>
  import { useDayjs } from '#dayjs' // not need if you are using auto import
  const dayjs = useDayjs()
  dayjs.locale('fr')
  dayjs.extend(...)
</script>

Configuration

You can specify any amount of locales, plugins, set a default locale, and set a default timezone

export default defineNuxtConfig({
  modules: ['dayjs-nuxt'],
  dayjs: {
    locales: ['en', 'fr'],
    plugins: ['relativeTime', 'utc', 'timezone'],
    defaultLocale: 'en',
    defaultTimezone: 'America/New_York',
  }
})

By default we include the relativeTime and utc plugins, and always import updateLocale

External Plugins

export default defineNuxtConfig({
  modules: ['dayjs-nuxt'],
  dayjs: {
    ...
    externalPlugins: [{
      name: 'dayjsBusinessDays',
      package: 'dayjs-business-days2',
      option: {
        holidays: [`2023-12-26`],
        holidayFormat: `YYYY-MM-DD`,
      }
    }]
    ...
  }
})

Optional defaultLocale customization

Instead of a locale string in defaultLocale:, you can define an array with a custom locale. See dayjs customization for more information.

Here is an example for a relativeTime configuration, lets create one that Gollum would understand:

export default defineNuxtConfig({
  modules: ['dayjs-nuxt'],
  dayjs: {
    ...
    defaultLocale: ['en', {
      relativeTime: {
        future: "in %s",
        past: "%s ago",
        s: 'a few secondses',
        m: "a minute",
        mm: "%d minuteses",
        h: "an hour",
        hh: "%d hourses",
        d: "a day",
        dd: "%d dayses",
        M: "a month",
        MM: "%d monthseses",
        y: "a year",
        yy: "%d yearseses"
      }
    }]
    ...
  }
})
