Options

Also, you can define some options.

Result option

var options = {
    result: 'FILE_INFORMATION'
};

faviconLoader(requestUrl, imageFolder, options)
.then(function(res){
    console.log(res)
})

Result options 'FILE_INFORMATION'

FILE_INFORMATION forces that the result comes as a file information object.

{ 
    path: '/Users/path/to/the/icon/bestIco.png',
    basename: 'bestIco.png',
    extention: '.png',
    mimetype: 'image/png' 
}

Result options 'FILE_DATA'

FILE_DATA forces that the result comes as a file data object. So that you have not to load the file afterwards.

{
    resource: 'local',
    path: '/Users/path/to/the/icon/bestIco.png',
    extention: '.png',
    content_type: 'image/png',
    uridata: 'data:image/png;base64,iVBOR…….TkSuQmCC' 
}

Default Icon option

You can define your own default icon.

var options = {
    result: 'FILE_DATA',
    default_icon: path.join(__dirname,'./default.png')
};

faviconLoader(requestUrl, imageFolder, options)
.then(function(res){
    console.log(res)
})
