Each component may be specified in one of the following formats:
- an application component ID as specified via $components.
- a module ID as specified via $modules.
- a class name.

'alias' => [
'@alias1' => 'to/path1',
'@alias2' => 'to/path2',
],
]
The "bootstrap" class listed above will be instantiated during the application bootstrapping process. If the class implements yii\base\BootstrapInterface, its bootstrap() method will be also be called.
If not set explicitly in the application config, this property will be populated with the contents of
@vendor/yiisoft/extensions.php
.
