- * 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 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.
