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, try to fetch that icon. If both fail, then it will query https://www.google.com/s2/favicons?domain=example.com
To use
case Faviconic.fetch("google.com") do
{:ok, image} -> image # image itself is returned
{:error, error_message} -> IO.inspect(error_message)
end
case Faviconic.get("google.com") do
{:ok, url} -> url # icon URL is returned
{:error, error_message} -> IO.inspect(error_message)
end
