/**
* Allows you to combine and compress your JavaScript and CSS files.
*
* Usage:
*
* 1. Create a configuration file using the `template` action:
*
* yii asset/template /path/to/myapp/config.php
*
* 2. Edit the created config file, adjusting it for your web application needs.
* 3. Run the 'compress' action, using created config:
*
* yii asset /path/to/myapp/config.php /path/to/myapp/config/assets_compressed.php
*
* 4. Adjust your web application config to use compressed assets.
*
* Note: in the console environment some [path aliases](guide:concept-aliases) like `@webroot` and `@web` may not exist,
* so corresponding paths inside the configuration should be specified directly.
*
* Note: by default this command relies on an external tools to perform actual files compression,
* check [[jsCompressor]] and [[cssCompressor]] for more details.
*
* @property \yii\web\AssetManager $assetManager Asset manager instance. Note that the type of this property
* differs in getter and setter. See [[getAssetManager()]] and [[setAssetManager()]] for details.

* @var array list of asset bundles, which represents output compressed files.
* You can specify the name of the output compressed file using 'css' and 'js' keys:
* For example:
*
* ```php
* 'app\config\AllAsset' => [
* 'js' => 'js/all-{hash}.js',
* 'css' => 'css/all-{hash}.css',
* 'depends' => [ ... ],

* ```
*
* File names can contain placeholder "{hash}", which will be filled by the hash of the resulting file.
*
* You may specify several target bundles in order to compress different groups of assets.
* In this case you should use 'depends' key to specify, which bundles should be covered with particular
* target bundle. You may leave 'depends' to be empty for single bundle, which will compress all remaining
* bundles in this case.
* For example:
*
* ```php
* 'allShared' => [
* 'js' => 'js/all-shared-{hash}.js',
* 'css' => 'css/all-shared-{hash}.css',
* 'depends' => [
* // Include all assets shared between 'backend' and 'frontend'

* 'app\assets\SharedAsset',

* // Include only 'backend' assets:
* 'app\assets\AdminAsset'
* ],
* ],
* 'allFrontEnd' => [
