Next.js

Step 1: Install the next-themes Library

Begin the process by installing the next-themes library, which simplifies theme management in Next.js applications:

npm install next-themes

Step 2: Create a Dedicated Theme Provider Component

"use client";

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

Step 3: Integrate the Theme Provider into Your Root Layout

Incorporate the newly created ThemeProvider component into your application's root layout file. Additionally, add the suppressHydrationWarning prop to the <html> tag to prevent potential hydration mismatches related to theme changes.

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>
    </>
  );
}

Step 4: Include a Component for Toggling the Theme

Integrate a user interface element, such as a button or switch, into your site's layout that will serve as a mode toggle, allowing users to easily switch between light and dark themes.
