暗黑模式

使用next-themes库

如何使用

1.安装

npm i next-themes

2.新增/components/ThemeProvider/index.tsx文件

'use client';

import { ThemeProvider as NextThemesProvider } from 'next-themes';
import * as React from 'react';

export default function ThemeProvider({ children, ...props }: React.ComponentProps<typeof NextThemesProvider>) {
  return <NextThemesProvider {...props}>
           {children}
         </NextThemesProvider>;
}

1. /app/layout.tsx文件中注入ThemeProvider:

import { ThemeProvider } from "@/components/theme-provider"

export default function RootLayout({ children }: RootLayoutProps) {
  return (
    <>
      <html lang="en" suppressHydrationWarning>
        <head />
        <body>
          <ThemeProvider
            attribute="class"
            defaultTheme="system"
            enableSystem
            disableTransitionOnChange
          >
            {children}
          </ThemeProvider>
        </body>
      </html>
    </>
  )
}

1. 新增/components/ThemeModeButton/index.tsx主题切换组件

'use client';

import { Moon, Sun } from 'lucide-react';
import { useTheme } from 'next-themes';

import { Button } from '@/components/ui/button';

export default function ThemeModeButton() {
  const { theme, setTheme } = useTheme();

  return (
        <Button variant="ghost" size="icon" 
        onClick={() => setTheme(theme === 'light' ? 'dark' : 'light')}>
            <Sun className="h-[1.2rem] w-[1.2rem] rotate-0 scale-100 transition-all dark:-rotate-90 dark:scale-0" />
            <Moon className="absolute h-[1.2rem] w-[1.2rem] rotate-90 scale-0 transition-all dark:rotate-0 dark:scale-100" />
           <span className="sr-only">切换主题</span>
        </Button>
  );
}
