Reusable Components & Widgets

Hi Guys,

When I look at the Yii-Framework I see many features which are being currently kind of a hype.

Im talking about resusable components how react or angular(2) are solving this problems.

In Yii we have powerful features like widgets, components or partial views to make reusable components.

Are there ideas or considerations to improve this reusable widget-way of yii2? Or to make a bridge to

a js framework like react? This would maybe mean to transform the big amount of yii widgets and components to convert to js widgets. Are there ways to use this action-dispatch philosophy also in yii2 widgets, so each widget is self updatable and listens for "news".
