Now, you can create you server driven widgets from RegisterSEWidget

Simple example:

...
class RestWidget extends RegisterSEWidget
{
      public $rest;
      public function init()
      {
         if( \Yii::$app->user->isGuest )
            throw new ForbiddenHttpException();
         $this->object='user';
         $this->id=\Yii::$app->user->id;
         $restJs=<<<JS
function(data){
    if(data['rest']){
        el = $('div.rest);
        if(el.length)
            el.html(data.rest);
    }
}
JS;
         $this->handlers=[  
            'rest'=>$restJs // добавляем обработчик
         ];
         parent::init();
      }

      public function run()
      {
         parent::run();
         return Html::tag('div',$this->rest.'&#8381;',['class'=>'rest']);
      }

   }   

After add widget to view you can update user rest in client browser from server.

SE::emit('user',$user_id,['handler'=>'rest','data'=>['rest'=>200.00]);
