How can I load fonts in Vite?

Loading local fonts

Create the following folder structure (this example uses the Roboto custom font):

Roboto/
├─ Roboto-Bold.woff2
├─ Roboto-Heavy.woff2
├─ Roboto.css

In the Roboto.css file, add the following code:

@font-face {
  font-family: 'Roboto';
  src: url('./Roboto-Bold.woff2') format('woff2');
  font-weight: 700;
  font-style: normal;
}

@font-face {
  font-family: 'Roboto';
  src: url('./Roboto-Heavy.woff2') format('woff2');
  font-weight: 900;
  font-style: normal;
}

Then import the Roboto.css file at the root of your application and add the font to your theme:

import {
  createTheme,
  DEFAULT_THEME,
  MantineProvider,
} from '@mantine/core';

import '@mantine/core/styles.css';
import './Roboto/Roboto.css';

const theme = createTheme({
  fontFamily: 'Roboto, sans-serif',
  fontFamilyMonospace: 'Monaco, Courier, monospace',
  headings: {
    // Use default theme if you want to provide default Mantine fonts as a fallback
    fontFamily: `Roboto, ${DEFAULT_THEME.fontFamily}`,
  },
});

function Demo() {
  return (
    <MantineProvider theme={theme}>Your app here</MantineProvider>
  );
}

Load fonts from Google Fonts

Select the fonts you want to use at Google Fonts and copy the HTML code snippet. For example, to load the Roboto font, the code you receive from Google Fonts will look something like this:

<link rel="preconnect" href="https://fonts.googleapis.com" />
<link rel="preconnect" href="https://fonts.gstatic.com" crossorigin />
<link
  href="https://fonts.googleapis.com/css2?family=Roboto:wght@300;400;500;700&display=swap"
  rel="stylesheet"
/>

Add the code to the <head /> of your application's index.html file. The code will look something like this:

<!doctype html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <link rel="icon" type="image/svg+xml" href="/src/favicon.svg" />
    <meta
      name="viewport"
      content="minimum-scale=1, initial-scale=1, width=device-width, user-scalable=no"
    />
    <link rel="preconnect" href="https://fonts.googleapis.com" />
    <link
      rel="preconnect"
      href="https://fonts.gstatic.com"
      crossorigin
    />
    <link
      href="https://fonts.googleapis.com/css2?family=Roboto:wght@300;400;500;700&display=swap"
      rel="stylesheet"
    />
    <title>Vite + Mantine App</title>
  </head>
  <body>
    <div id="root"></div>
    <script type="module" src="/src/main.tsx"></script>
  </body>
</html>

Then add the font to your theme:

import {
  createTheme,
  DEFAULT_THEME,
  MantineProvider,
} from '@mantine/core';

import '@mantine/core/styles.css';

const theme = createTheme({
  fontFamily: 'Roboto, sans-serif',
  fontFamilyMonospace: 'Monaco, Courier, monospace',
  headings: {
    // Use default theme if you want to provide default Mantine fonts as a fallback
    fontFamily: `Roboto, ${DEFAULT_THEME.fontFamily}`,
  },
});

function Demo() {
  return (
    <MantineProvider theme={theme}>Your app here</MantineProvider>
  );
}
