Nuxt Color Mode
🌃 Dark and 🌞 Light mode with auto detection (even on server side!) made easy
This module is similar to the official module @nuxtjs/color-mode but with cookie support and server side system preference (via sec-ch-prefers-color-scheme header), making sure that the rendered theme on the server and client is always in sync.
It's not a 1:1 port of @nuxtjs/color-mode so expect a few API changes or missing features.
Features
- 🚀 Full SSR support
- 🍪 Cookie support
- 🤖 Auto detect system color mode (even on server side!)
- 🎨 Customizable
- 🌪️ Temporary force color mode on individual pages or actions
Quick Setup
Install the module to your Nuxt application with one command:
npx nuxi module add @eschricht/nuxt-color-modeThat's it! You can now use Nuxt Color Mode in your Nuxt app ✨
Configuration
export default defineNuxtConfig({
modules: ['@eschricht/nuxt-color-mode'],
colorMode: {
// The preferred mode when cookie hasn't been set yet
preference: 'system',
// Fallback to use when system preference is unavailable
fallback: 'light',
// Name to use when system preference is 'dark'
systemDarkName: 'dark',
// Name to use when system preference is 'light'
systemLightName: 'light',
// Prefix color mode class name
classPrefix: '',
// Suffix color mode class name
classSuffix: '-mode',
// Adds a data-attribute to the HTML.
// Example, set it to 'color-mode' will add the HTML attribute 'data-color-mode="<color-mode>"'
dataValue: '',
// Name of the cookie
cookieName: 'color-mode',
// Cookie options
cookieOptions: {},
}
})Composable
The composable returns a reactive object containing information about the current color theme.
[!WARNING] Do not destruct the return value. Since it's a reactive object, reactivity will be lost.
Usage
<script setup lang="ts">
const colorMode = useColorMode()
console.log(colorMode.preference) // The current value stored in cookie, i.e. 'system'
console.log(colorMode.system) // The system preference, i.e. 'dark'. - Readonly
console.log(colorMode.value) // The resolved color mode, i.e. 'dark' or 'github-dark' if systemDarkName: 'github-dark' - Readonly
function changeColorMode() {
colorMode.preference = 'some-other-value' // Updates cookie value and HTML class is set to `<html class="some-other-value-mode">`
}
</script>Force color mode
It's possible to temporarily force the color mode on specific pages or situations. This can be done in 3 ways:
definePageMeta
<script setup lang="ts">
definePageMeta({
colorMode: 'pink'
})
</script>Composable
<script setup lang="ts">
const { forceColorMode } = useColorMode()
function handleError() {
forceColorMode('error')
}
function resetError() {
// Reset
forceColorMode()
}
</script>$colorMode.forcedValue
<template>
<div>
<button @click="$colorMode.forcedValue = 'pink'">FORCE 🌪️</button>
