How to use @next/font globally

#nextjs #font #css

The @next/font package can download Google Fonts at build time and self-host them as a static asset. This is useful because no requests are made to Google by the client to request fonts used on the page.

However, it wasn't obvious to me how to apply the font globally. This can be achieved as follows.

app.js 

import "@/styles/globals.css";

import { DM_Sans } from "@next/font/google";

const dm_sans = DM_Sans({
  display: "swap",
  subsets: ["latin"],
  weight: ["400", "500", "700"],
});

export default function App({ Component, pageProps }) {
  return (
    <>
      <style jsx global>{`
        :root {
          --dm-font: ${dm_sans.style.fontFamily};
        }
      `}</style>
      <Component {...pageProps} />
    </>
  );
}
Enter fullscreen mode Exit fullscreen mode

And then use the CSS variable in your stylesheet.

global.css 

body {
  font-family: var(--dm-font);
}
Enter fullscreen mode Exit fullscreen mode

Hello! Did you find any way to use this with the app folder?

/src/app/layout.tsx

import { Open_Sans, Playfair_Display } from '@next/font/google';

import './globals.scss';

const openSans = Open_Sans({
  display: 'swap',
  subsets: [ 'latin' ],
  weight: [ '400', '500', '700' ],
  variable: '--font-open-sans',
});

const playfairDisplay = Playfair_Display({
  display: 'swap',
  subsets: [ 'latin' ],
  weight: [ '500' ],
  variable: '--font-playfair-display',
});

const RootLayout: FC<PropsWithChildren> = ({ children }) => (
  <html lang="en" className={`${openSans.variable} ${playfairDisplay.variable}`}>
    <body>
      {children}
    </body>
  </html>
);

export default RootLayout;
Enter fullscreen mode Exit fullscreen mode

/src/app/global.scss

.foo {
  font-family: var(--font-open-sans);
}
Enter fullscreen mode Exit fullscreen mode
