Next.js

Adding dark mode to your next app.

Install next-themes

Start by installing next-themes:


pnpm add next-themes

Create a theme provider

components/theme-provider.tsx

"use client"   import * as React from "react" import { ThemeProvider as NextThemesProvider } from "next-themes"   export function ThemeProvider({  children,  ...props }: React.ComponentProps<typeof NextThemesProvider>) {  return <NextThemesProvider {...props}>{children}</NextThemesProvider> }

Wrap your root layout

Add the ThemeProvider to your root layout and add the suppressHydrationWarning prop to the html tag.

app/layout.tsx

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>  </>  ) }

Add a mode toggle

Place a mode toggle on your site to toggle between light and dark mode.

"use client"  import * as React from "react" import { Moon, Sun } from "lucide-react" import { useTheme } from "next-themes"  import { Button } from "@/components/ui/button" import {  DropdownMenu,  DropdownMenuContent,  DropdownMenuItem,  DropdownMenuTrigger, } from "@/components/ui/dropdown-menu"  export function ModeToggle() {  const { setTheme } = useTheme()   return (  <DropdownMenu>  <DropdownMenuTrigger asChild>  <Button variant="outline" size="icon">  <Sun className="h-[1.2rem] w-[1.2rem] scale-100 rotate-0 transition-all dark:scale-0 dark:-rotate-90" />  <Moon className="absolute h-[1.2rem] w-[1.2rem] scale-0 rotate-90 transition-all dark:scale-100 dark:rotate-0" />  <span className="sr-only">Toggle theme</span>  </Button>  </DropdownMenuTrigger>  <DropdownMenuContent align="end">  <DropdownMenuItem onClick={() => setTheme("light")}>  Light  </DropdownMenuItem>  <DropdownMenuItem onClick={() => setTheme("dark")}>  Dark  </DropdownMenuItem>  <DropdownMenuItem onClick={() => setTheme("system")}>  System  </DropdownMenuItem>  </DropdownMenuContent>  </DropdownMenu>  ) }
