Importing and loading

Specify the URL

This component imports icons through dynamic import.

The target module needs to export a function by default.

toURL is defaults to (name) => `./icons/${name}.js`.

The base of the import URL defaults to the import.meta.url of the element declaration file (./element.js).

import F7Icon from "@godown/f7-icon";

const i = new F7Icon();
i.toURL = function (name: string) {
  return "specified URL or string";
};

Example CDNs.

If the icons are not built jointly, or use an icon library with a different base than component, this could be useful.

i.toURL =
  /* esm.sh */
  (name) => `https://esm.sh/@godown/f7-icon/icons/${name}.js`;

/* jsDelivr */
// (name) => `https://esm.run/@godown/f7-icon/icons/${name}.js`;

/*  unpkg */
// (name) => `https://unpkg.com/@godown/f7-icon/icons/${name}.js?module`;
