创建内联主题脚本

import '../styles/globals.css'

<script is:inline>
const getThemePreference = () => {
if (typeof localStorage !== 'undefined' && localStorage.getItem('theme')) {
return localStorage.getItem('theme');
}
return window.matchMedia('(prefers-color-scheme: dark)').matches ? 'dark' : 'light';
};
const isDark = getThemePreference() === 'dark';
document.documentElement.classList[isDark ? 'add' : 'remove']('dark');
if (typeof localStorage !== 'undefined') {
const observer = new MutationObserver(() => {
const isDark = document.documentElement.classList.contains('dark');
localStorage.setItem('theme', isDark ? 'dark' : 'light');
});
observer.observe(document.documentElement, { attributes: true, attributeFilter: ['class'] });
}

安装依赖项
bash
npm install @vueuse/core
可选,用于包含主题按钮图标。
bash
npm install -D @iconify/vue @iconify-json/radix-icons
添加模式切换
在您的网站上放置一个模式切换按钮,用于在亮色和暗色模式之间切换。
我们使用的是来自 @vueuse/core
的 useColorMode
。
带自动数据持久化的响应式颜色模式(暗色/亮色/自定义)。
vue
<script setup lang="ts">
import { useColorMode } from '@vueuse/core'
import { Icon } from '@iconify/vue'
import { Button } from '@/components/ui/button'
import { DropdownMenu, DropdownMenuContent, DropdownMenuItem, DropdownMenuTrigger } from '@/components/ui/dropdown-menu'
const mode = useColorMode()
</script>
<template>
<DropdownMenu>
<DropdownMenuTrigger as-child>
<Button variant="outline">
<Icon icon="radix-icons:moon" class="h-[1.2rem] w-[1.2rem] rotate-0 scale-100 transition-all dark:-rotate-90 dark:scale-0" />
<Icon icon="radix-icons:sun" class="absolute h-[1.2rem] w-[1.2rem] rotate-90 scale-0 transition-all dark:rotate-0 dark:scale-100" />
<span class="sr-only">Toggle theme</span>
</Button>
</DropdownMenuTrigger>
<DropdownMenuContent align="end">
