Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The style read-only property of the FontData interface returns the style of the font face.

Examples include:

  • UltraLight
  • Regular
  • Heavy
  • Medium Italic
  • Extrabold

A string.

Examples

The following snippet will query for all available fonts, and log metadata. This could be used, for example, to populate a font-picker control.

async function logFontData() {
  try {
    const availableFonts = await window.queryLocalFonts();
    for (const fontData of availableFonts) {
      console.log(fontData.postscriptName);
      console.log(fontData.fullName);
      console.log(fontData.family);
      console.log(fontData.style);
    }
  } catch (err) {
    console.error(err.name, err.message);
  }
}
