How to Use Google Fonts in a Next.js App

Google Fonts is a free and open-source font repository that offers a wide range of fonts for web developers to use on their websites. With Next.js, integrating Google Fonts into your app is a straightforward process that can be done by adding the font import to either the _document.js or _app.js file.

When choosing a font to use on your Next.js app, it's important to consider factors such as readability, style, and branding. Fonts can affect the readability and legibility of your app's text, which can ultimately affect the user's experience. Choosing a font that is easy to read and fits your app's style and branding can make a big difference in how users perceive your app.

Google Fonts offers a wide variety of fonts to choose from, ranging from classic serif fonts to modern sans-serif fonts. The Google Fonts website makes it easy to browse and search for fonts, and it provides helpful information such as font pairings and usage examples.

Once you have selected a font to use, you can add it to your Next.js app by adding the font import to either the _document.js or _app.js file. Adding the font import to the _document.js file is the recommended approach if you want to apply the font to all pages of your app. Here's an example of how you can add the Google Fonts import to the _document.js file:

import Document, { Html, Head, Main, NextScript } from 'next/document';

class MyDocument extends Document {
  render() {
    return (
      <Html>
        <Head>
          <link
            href="https://fonts.googleapis.com/css?family=Open+Sans"
            rel="stylesheet"
          />
        </Head>
        <body>
          <Main />
          <NextScript />
        </body>
      </Html>
    );
  }
}

export default MyDocument;

In this example, we're importing the Open Sans font using a link element in the head section of the HTML document. This will apply the font to all pages of the app.

Alternatively, you can also add the font import to the _app.js file if you want to apply the font to all pages of the app, but only within the context of the app. Here's an example of how you can add the Google Fonts import to the _app.js file:

import '../styles/global.css';

function MyApp({ Component, pageProps }) {
  return <Component {...pageProps} />;
}

export default MyApp;

It's worth noting that using custom fonts can affect the performance of your app, as they can add extra weight to your page and slow down its loading time. To mitigate this, you can use font-loading strategies like font-display and font-loading APIs to optimize the loading of your fonts.

Overall, using Google Fonts in your Next.js app is a great way to add a touch of creativity and personality to your app's design. By taking the time to choose the right font and integrating it properly into your app, you can create a more engaging and enjoyable user experience.
