laravel transformer custom return format

• Customize a CustomSerializer class as follows:

use League\Fractal\Serializer\ArraySerializer;
class CustomSerializer extends ArraySerializer{    
    public function collection($resourceKey, array $data)     
    {         
        return ['custom-data-name' => $data];     
    }    
    public function item($resourceKey, array $data)     
    {         
        return ['custom-data-name' => $data];     
    } 
}

• The data transformer is returned as follows

return $this->collection($users, new UserTransformer, function ($resource, $fractal) {
    $fractal->setSerializer(new CustomSerializer);
});
