You can programmatically access Favicons configuration (icon filenames, HTML, manifest files, etc) with:

  1. ```js
  2. import { config } from "favicons";
  3. ```

Output


For the full list of files, check config/files.json. For the full HTML code, check config/html.js. Finally, for the full list of icons, check config/icons.json.

Questions


Why are you missing certain favicons?


Because pure Javascript modules aren't available at the moment. For example, the El Capitan SVG favicon and the Windows tile silhouette ability both require SVG support. If modules for these task begin to appear, please jump on the appropriate issue and we'll get on it ASAP.
