Sprockets::Context#asset_data_uri

Returns a Base64-encoded `data:` URI with the contents of the
asset at the specified path, and marks that path as a dependency
of the current file.

Use `asset_data_uri` from ERB with CSS or JavaScript assets:

    #logo { background: url(<%= asset_data_uri 'logo.png' %>) }

    $('<img>').attr('src', '<%= asset_data_uri 'avatar.jpg' %>')
