How to get application component id?

Question

Yii

How to get the application component id inside the application itself?
For example, I connect a component to the application in the config:

'components' => [
    'TestComponent' => [
         'class' => 'app\components\MyComponent'
    ],
]

where is the id of the component in the application TestComponent. How do I know inside the component itself is the ID?

You need to take all the components and look for instanceof app\components\MyComponent.
It is better to pass as a parameter what you need.

'components' => [
    'TestComponent' => [
         'class' => 'app\components\MyComponent',
         'myProp' => 'Whatever you need' //myProp - публичное свойство компонента
    ],
