πŸŒ“ Theme your Next.js apps with a Dark Mode

license npm bundle size npm version



Auto mode

next-dark-mode optionally supports auto mode which automatically switches the user's theme as per the color mode selected on their operating system.

Windows and macOS both support setting the dark or light mode based on the time of the day.

It is achieved via prefers-color-scheme media query.

No page load glitch

next-dark-mode uses configurable cookies to persist the state of the current theme, one for the auto mode and the other for the dark mode.

This prevents the common page load glitch with the local storage approach where the app loads on the client and then the state of the user's theme is fetched.

You can see it in this implementation by Pantaley Stoyanov.

NOTE: This library is not compatible with Next.js 9's Auto Partial Static Export feature as it has to read the cookies in getInitialProps function, which makes all pages incompatible with Automatic Partial Static Export feature.


To use next-dark-mode, you must use react@16.8.0 or greater which includes Hooks.


$ yarn add next-dark-mode


$ npm install next-dark-mode


  1. Wrap your _app.js component (located in /pages) with the HOC withDarkMode

    // _app.js
    import App from 'next/app'
    import withDarkMode from 'next-dark-mode'
    export default withDarkMode(App)
  2. You can now use the useDarkMode hook anywhere in your app

    import { useDarkMode } from 'next-dark-mode'
    const MyComponent = props => {
      const {
        autoModeActive,    // boolean - whether the auto mode is active or not
        autoModeSupported, // boolean - whether the auto mode is supported on this browser
        darkModeActive,    // boolean - whether the dark mode is active or not
        switchToAutoMode,  // function - toggles the auto mode on
        switchToDarkMode,  // function - toggles the dark mode on
        switchToLightMode, // function - toggles the light mode on
      } = useDarkMode()

With CSS-in-JS libraries (like emotion or styled-components)

  1. Wrap your _app.js component (located in /pages) with the HOC withDarkMode and pass the values to the ThemeProvider so that you can use it in your components

    // _app.js
    import { ThemeProvider } from '@emotion/react' // or styled-components
    import withDarkMode from 'next-dark-mode'
    function MyApp({ Component, darkMode, pageProps }) {
      const { autoModeActive, autoModeSupported, darkModeActive } = darkMode
      return (
        <ThemeProvider theme={{ darkMode: darkModeActive, ...(other values) }}>
          <Component {...pageProps} />
    export default withDarkMode(MyApp)


The withDarkMode function accepts a config object as its second argument. Every key is optional with default values mentioned:

  • autoModeCookieName: string - Name of the cookie used to determine whether the auto preset is enabled. Defaults to 'autoMode'.
  • cookieOptions: object - Configuration options for the cookies that gets set on the client. Defaults to { sameSite: 'lax' }.
  • darkModeCookieName: string - Name of the cookie used to determine whether the dark preset is enabled. Defaults to 'darkMode'.
  • defaultMode: string - Determines the default color mode when there's no cookie set on the client. This usually happens on the first ever page load. It can either be 'dark' or 'light' and it defaults to 'light'.
