# Nextjs Darkmode 
[](https://github.com/react18-tools/nextjs-darkmode/actions/workflows/test.yml) [](https://codeclimate.com/github/react18-tools/nextjs-darkmode/maintainability) [](https://codecov.io/gh/react18-tools/nextjs-darkmode) [](https://www.npmjs.com/package/nextjs-darkmode) [](https://www.npmjs.com/package/nextjs-darkmode)  [](https://gitpod.io/from-referrer/)
Nextjs Darkmode is a versatile library crafted to fully utilize React 18 server components, ensuring a seamless dark mode experience in Next.js applications. Lightweight and efficient, it respects both user preferences and system settings through the prefers-color-scheme media query, and integrates effortlessly with React/Vite, Remix, and Next.js.
## Motivation
The `nextjs-themes` library was initially created to achieve a similar functionality to `next-themes` with React Server Components. While effective, it felt bulky for those supporting only dark/light mode. Thus, `nextjs-darkmode` was developed to offer a minimal footprint while utilizing Next.js Server Components, avoiding any flash of unthemed content, and ensuring theme synchronization with the server.
> For migration guide please refer [Project Wiki](https://github.com/react18-tools/nextjs-darkmode/wiki/1.-Migration-guide)

Getting Started
### Installation
```bash
$ pnpm add nextjs-darkmode
```
**_or_**
```bash
$ npm install nextjs-darkmode
```
**_or_**
```bash
$ yarn add nextjs-darkmode
```
### Import Styles
> PLease make sure you set `"moduleResolution"` to `"Bundler"`, `"Node16"` or `"NodeNext"` in your tsconfig file for export field in package.json to work properly. (Ref)[https://stackoverflow.com/a/74462490/23175171]
> You may need to import styles from `nextjs-darkmode/dist/index.css` depending on your bundler configuration.
Import styles globally or within layout component.
```css
/* globals.css */
@import "nextjs-darkmode/css";
```
```tsx
// layout.tsx
import "nextjs-darkmode/css";
```
### Lite Version
For a lighter version, use `nextjs-darkmode-lite`:
[](https://www.npmjs.com/package/nextjs-darkmode-lite) [](https://www.npmjs.com/package/nextjs-darkmode-lite) [](https://www.npmjs.com/package/nextjs-darkmode-lite)
```bash
$ pnpm add nextjs-darkmode-lite
```
**_or_**
```bash
$ npm install nextjs-darkmode-lite
```
**_or_**
```bash
$ yarn add nextjs-darkmode-lite
```
> You need `r18gs` as a peer-dependency.
## Usage
> Please explore `examples` and `packages/shared-ui` for more working examples. (updates coming soon...)
### SPA (e.g., Vite, CRA) and Next.js pages directory
Modify `_app` to add dark mode support:
```js
import { Core } from "nextjs-darkmode"; // for better tree-shaking
import { Switch } from "nextjs-darkmode/switch";
function MyApp({ Component, pageProps }) {
return (
<>
>
);
}
export default MyApp;
```
⚡🎉Boom! Just a couple of lines and your dark mode is ready, complete with a color switch for user preferences. Check out examples for advanced usage.
> For `vite` or any other build tool, find a similar root component, e.g., `` in `CRA` and `vite`.
### With Next.js `app` router
Update `app/layout.jsx` to add `Core` component.
```tsx
// app/layout.jsx
import { Core } from "nextjs-darkmode"; // for better tree-shaking
export default function Layout({ children }) {
return (
{children}
);
}
```
### Switch
An elegant color switch to toggle color schemes:
```tsx
```
### HTML & CSS
Fully support dark mode, including system preference with `prefers-color-scheme`. The dark/light mode is synced between tabs and modifies the `className` and data-attributes on the `html` elemnt.
```css
:root {
--background: white;
--foreground: black;
}
.dark {
--background: black;
--foreground: white;
}
/* or */
[data-rm="dark"] {...}
```
#### Using the data-attributes
data-attributes are very helpful when you want to customize styles in a CSS module file (`styles.module.css`)
`data-rm` -> Resolved Mode
`data-m` -> User's preference
`data-sm` -> System preference
#### Content Security Policy
If you are using CSP rules for CSS files, you can pass `nonce` argument to the `Core` component. If `nonce` is not supplied transition styles will not be applied. This may allow patched transitions throught the page in some cases.
```tsx
```
### Images
Show different images based on the current theme:
```ts
import Image from "next/image";
import { useMode } from "nextjs-darkmode/hooks";
function ThemedImage() {
const { resolvedMode } = useMode();
let src;
switch (resolvedMode) {
case "light":
src = "/light-mode-image.png";
break;
case "dark":
src = "/dark-mode-image.png";
break;
default:
src = "/default-image.png";
break;
}
return ;
}
```
### useMode
The `useMode` hook provides mode information:
```js
import { useMode } from "nextjs-darkmode";
const ThemeChanger = () => {
const { resolvedMode, setMode } = useMode();
return (
The current resolved mode is: {resolvedMode}
setMode("light")}>Light Mode
setMode("dark")}>Dark Mode
);
};
```
`useMode` hook returns the following object:
```ts
export interface UseModeInterface {
mode: ColorSchemePreference;
systemMode: ResolvedScheme;
resolvedMode: ResolvedScheme;
setMode: (mode: ColorSchemePreference) => void;
}
```
### Force per page mode
Apply appropriate class names and data attributes to force a mode for the page:
```tsx
export default function Page() {
return
...;
}
```
### With Styled Components and any CSS-in-JS
Next Themes works with any library. For example, with Styled Components:
```js
// pages/_app.js
import { createGlobalStyle } from "styled-components";
import { Core } from "nextjs-darkmode";
// Your theming variables
const GlobalStyle = createGlobalStyle`
:root {
--fg: #000;
--bg: #fff;
}
[data-rm="dark"] {
--fg: #fff;
--bg: #000;
}
`;
function MyApp({ Component, pageProps }) {
return (
<>
>
);
}
```
### With Tailwind
In `tailwind.config.js`, set the dark mode property to class:
```js
// tailwind.config.js
module.exports = {
darkMode: "class",
};
```
Now you can use dark-mode specific classes:
```tsx
```
## Performance
`nextjs-darkmode` is designed to be fully tree-shakable, including only the code you use. For instance, if you only use the `useMode` hook, the rest of the library's code will be removed during the build process.
