Caching support for Yii2 widgets
The preferred way to install this extension is through composer.
Run
php composer.phar require pozitronik/yii2-cachedwidget "dev-master"
or add
"pozitronik/yii2-cachedwidget": "dev-master"
to the require section of your composer.json file.
Yii2, PHP >= 7.2.0
Once the extension is installed, simply inherit any widgets from pozitronik\widgets\CachedWidget class instead of yii\base\Widget in your code.
CachedWidget has redefined render() method, that stores all rendered views in Yii2 global cache (with nested widgets, if its called in view file).
Widget handles correctly Yii2 view assets and inline resources, like js/css files or inline code inclusion.
Caching is disabled by default within YII_ENV_DEV environment (see $disable property).
class MyWidget extends \pozitronik\widgets\CachedWidget {
// it is all, mostly
}
