fetch-favicon

Fetch a favicon with multiple fallbacks.

Full online documentation is available here.

You can find the package on Hex here.

For example.com it will first try example.com/favicon.ico, then it will try to find the icon file path in the HTML, and if it does, try to fetch that icon. If both fail, then it will query https://www.google.com/s2/favicons?domain=example.com

The image itself is returned.

To use

case FetchFavicon.fetch("google.com") do
  {:ok, image} -> use_image(image)
  {:error, error_message} -> use_error(error_message)
end
