View Source Faviconic (faviconic v0.3.0)
Fetch a favicon from a URL, 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. If both fail, then it will try getting an icon from Duckduckgo and Google.
To use
case Faviconic.fetch("google.com") do
{:ok, image} -> image # image itself is returned
{:error, error_message} -> IO.inspect(error_message)
endcase Faviconic.get("google.com") do
{:ok, url} -> url # icon URL is returned
{:error, error_message} -> IO.inspect(error_message)
