Nextjs-Themes 
🤟 👉 Unleash the Power of React Server Components
This project is inspired by next-themes. Next-themes is an awesome package, however, it requires wrapping everything in a provider. The provider has to be a client component as it uses hooks. And thus, it takes away all the benefits of Server Components.
nextjs-themes-lite removes this limitation and enables you to unleash the full power of React 18 Server Components. In addition, more features are coming up soon... Stay tuned!

Use
With pages/
The best way is to add a Custom App to use by modifying _app as follows:
Adding dark mode support takes 2 lines of code:
import { ThemeSwitcher } from "next-themes";
function MyApp({ Component, pageProps }) {
return (
<>
<ThemeSwitcher forcedTheme={Component.theme} />
<Component {...pageProps} />
</>
);
}
export default MyApp;⚡🎉Boom! Just a couple of lines and your dark mode is ready!
Check out examples for advanced usage.
With app/
Update your app/layout.jsx to add ThemeSwitcher and SSCWrapper from nextjs-themes-lite. SSCWrapper is required to avoid flash of un-themed content on reload.
// app/layout.jsx
import { ThemeSwitcher } from "next-themes";
import { SSCWrapper } from "next-themes/server/nextjs";
export default function Layout({ children }) {
return (
<SSCWrapper tag="html" lang="en">
<head />
<body>
<ThemeSwitcher />
{children}
</body>
</SSCWrapper>
);
}Woohoo! You just added dark mode and you can also use Server Component! Isn't that awesome!
HTML & CSS
That's it, your Next.js app fully supports dark mode, including System preference with prefers-color-scheme. The theme is also immediately synced between tabs. By default, next-themes modifies the data-theme attribute on the html element, which you can easily use to style your app:
:root {
/* Your default theme */
--background: white;
--foreground: black;
}
[data-theme="dark"] {
--background: black;
--foreground: white;
}useTheme
In case your components need to know the current theme and be able to change it. The useTheme hook provides theme information:
import { useTheme } from "nextjs-themes-lite";
const ThemeChanger = () => {
/* you can also improve performance by using selectors
* const [theme, setTheme] = useTheme(state => [state.theme, state.setTheme]);
*/
const { theme, setTheme } = useTheme();
return (
<div>
The current theme is: {theme}
<button onClick={() => setTheme("light")}>Light Mode</button>
<button onClick={() => setTheme("dark")}>Dark Mode</button>
</div>
);
};Force per page theme and color-scheme
Next.js app router
import { ForceTheme } from "nextjs-themes-lite";
function MyPage() {
return (
<>
<ForceTheme theme={"my-theme"} />
...
</>
);
}
export default MyPage;Next.js pages router
For pages router, you have 2 options. One is the same as the app router and the other option which is compatible with next-themes is to add theme to your page component as follows.
function MyPage() {
return <>...</>;
}
MyPage.theme = "my-theme";
export default MyPage;In a similar way, you can also force color scheme.
Forcing color scheme will apply your defaultDark or defaultLight theme, configurable via hooks.
