How to publish an asset within a widget in Yii2

Question

In Yii 1 it was possible to publish an asset with:

Yii::app()->getAssetManager()->publish(Yii::getPathOfAlias('ext.MyWidget.assets'));

How can I publish an asset within a widget in Yii2?

Answer 1

In your view of your widget:

app\assets\AppAsset::register($this); // $this == the View object

Check the docs.

Answer 2

Simplest way of doing this:

app\assets\AppAsset::register($this->getView());

It is the same way you would publish it in a view.
