        fonts: {
          google: [
            {
              family: "Roboto", // 'font-family' property
              variants: ["300", "400", "500"],
              //subsets: ['latin'],
              //text: 'Hello',
              //fontDisplay: 'swap' || 'auto' || 'block' || 'fallback' || 'optional',
              //strategy: 'selfHosted' || 'base64' || 'cdn',
              // Other properties as per https://developer.mozilla.org/en-US/docs/Web/CSS/@font-face (except 'src' & 'font-family') can go here i.e.

            },
          ],
          selfHosted: [
            {
              family: "Open Sans",
              urls: {
                woff2: `/font/OpenSans400.woff2`,
                woff: `/font/OpenSans400.woff`,
                //[format]: '/[filepath]/[filename],
              },
              //[cssProperty]: 'value',
            },
          ],
        },

};

Google Fonts

Using Google’s Font API, name the font families you’d like to load.

module.exports = {
  plugins: [
    {
      resolve: `gatsby-plugin-webfonts`,
      options: {
        fonts: {
          google: [
            {
              family: "Roboto",
              variants: ["300", "400", "500"],
            },
            {
              family: "Open Sans Condensed",
              variants: ["300", "700"],
            },
          ],
        },
      },
    },
  ],
};

You can also supply the text parameter or array of subsets to perform character subsetting:

module.exports = {
  plugins: [
    {
      resolve: `gatsby-plugin-webfonts`,
      options: {
        fonts: {
          google: [
            {
              family: "Roboto",
              variants: ["300", "400", "500"],
              text: "Hello",
            },
            {
              family: "Roboto",
              variants: ["300", "400", "500"],
              subsets: ["latin", ""],
            },
          ],
        },
      },
    },
  ],
};

Pass you user-agent for specific font type:

module.exports = {
  plugins: [
    {
      resolve: `gatsby-plugin-webfonts`,
      options: {
        fonts: {
          google: [
            {
              family: "Roboto",
              variants: ["300", "400", "500"],
            },
          ],
        },
        formatAgents: {
          woff: `Mozilla/5.0 (Windows NT 10.0; WOW64; Trident/7.0; .NET4.0C; .NET4.0E; .NET CLR 2.0.50727; .NET CLR 3.0.30729; .NET CLR 3.5.30729; rv:11.0) like Gecko`,
          woff2: `Mozilla/5.0 (Windows NT 10.0; Win64; x64; ServiceUI 8) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/51.0.2704.79 Safari/537.36 Edge/14.14393`,
        },
      },
    },
  ],
};

The text subsetting functionality is only available for Google fonts.

Google Fonts v2

This is an extension of the “Google Fonts” setting which uses the latest API.

You can also use the latest Google Fonts API v2.

Use the axes option like so:

module.exports = {
  plugins: [
    {
      resolve: `gatsby-plugin-webfonts`,
      options: {
        fonts: {
          google2: [
            {
              family: "Roboto",
              axes: "wght@300;400;500",
            },
          ],
        },
      },
    },
  ],
};

A variable font packs all the styles and weights of a font family into a single file.

Only a few Google Fonts are available as variable fonts. Some have their own custom axes that can be set accordingly.

module.exports = {
  plugins: [
    {
      resolve: `gatsby-plugin-webfonts`,
      options: {
        fonts: {
          google2: [
            {
              family: "Rubik",
              axes: "wght@300..600", // multiple ranges are supported, ex: "wght@300..500;700..900"
            },
          ],
        },
      },
    },
  ],
};

Self Hosted Fonts

Add your own self hosted font files. The plugin will handle the imports & preloading. Strategy is always selfHosted, subsets are already defined within your font file.

module.exports = {
  plugins: [
    {
      resolve: `gatsby-plugin-webfonts`,
      options: {
        fonts: {
          selfHosted: [
            {
              family: "Open Sans",
              urls: {
                // src attributes
                // path relative to gatsby project root
                woff2: `/examplePath/filename.woff2`,
                woff: `/examplePath/filename.woff`,
                otf: `/examplePath/filename.otf`,
                ttf: `/examplePath/filename.ttf`,
              },
              fontStyle: "light",
              fontWeight: 300,
            },
          ],
        },
      },
    },
  ],
};

As per gatsby docs it is recommended not to put fonts in the /static directory. This plugin will automatically be copy them across to /public/webfonts/selfHosted.
