favoritos/src/helpers/load-image.ts

Favoritos is a JavaScript plugin that adds some HTML5 canvas magic to your favicon. With just a wee bit of code, we can make some really cool effects.

export const loadImage = (src: string, callback: Function): void => {
  const img = new Image();
  img.crossOrigin = 'anonymous';
  img.addEventListener(
    'load',
    () => {
      return callback(img);
    },
    { once: true }
  );
  img.addEventListener(
    'error',
    () => {
      return callback(img);
    },
    { once: true }
  );
  img.src = src;
};
