FontFace: load() method

Note: This feature is available in Web Workers.

The load() method of the FontFace interface requests and loads a font whose source was specified as a URL. It returns a Promise that resolves with the current FontFace object.

If the source for the font face was specified as binary data, or the font status property of the font face is anything other than unloaded, then this method does nothing.

Syntax

js
load()

Parameters

None.

Return value

A Promise that resolves with a reference to the current FontFace object when the font loads or rejects with a NetworkError DOMException if the loading process fails.

Exceptions

NetworkError DOMException

Indicates that the attempt to load the font failed.

Examples

This simple example loads a font and uses it to display some text in a canvas element (with an id of js-canvas).

js
const canvas = document.getElementById("js-canvas");

// load the "Bitter" font from Google Fonts
const fontFile = new FontFace(
  "FontFamily Style Bitter",
  'url("https://fonts.gstatic.com/s/bitter/v7/HEpP8tJXlWaYHimsnXgfCOvvDin1pK8aKteLpeZ5c0A.woff2")',
);
document.fonts.add(fontFile);

fontFile.load().then(
  () => {
    // font loaded successfully!
    canvas.width = 650;
    canvas.height = 100;
    const ctx = canvas.getContext("2d");

    ctx.font = '36px "FontFamily Style Bitter"';
    ctx.fillText("Bitter font loaded", 20, 50);
  },
  (err) => {
    console.error(err);
  },
);
