Font Face Observer is a small @font-face loader and monitor (3.5KB minified and 1.3KB gzipped) compatible with any webfont service. It will monitor when a webfont is loaded and notify you. It does not limit you in any way in where, when, or how you load your webfonts. Unlike the Web Font Loader Font Face Observer uses scroll events to detect font loads efficiently and with minimum overhead.

var font = new FontFaceObserver('My Family', {
  weight: 400
});

font.load().then(function () {
  console.log('Font is available');
}, function () {
  console.log('Font is not available');
});

$ npm install fontfaceobserver
