Obtain the ViewContainerRef of the AppComponent

Currently, I am searching for a method to obtain the ViewContainerRef of the AppComponent using a service.

I have come across various sources online such as this article, this blog post, and this forum thread, but they are all tailored to older versions of Angular (I am utilizing version 6).

My goal is to retrieve this reference without manually setting it through a setter function.

Currently, my workaround involves injecting ViewContainerRef into AppComponent and passing it to the service.

Instead, I aim to access the reference directly in the service by using an injected provider. For instance:

  constructor(
    private applicationRef: ApplicationRef
  ) {
    this.viewContainerRef = applicationRef.getAppViewRef();
  }

This functionality is needed for dynamically creating components and adding them to the document, either at the body level or within the AppComponent. This would enable me to generate notifications, dialogs, and more.

Answer №1

Feel free to utilize it just as shown in the provided link. I have set up a stackblitz example here: Within the AppService, I am injecting the ApplicationRef and using attachView to insert a DummyComponent into the AppComponent within the app body.

This method appears to be functioning similarly to previous versions.

Answer №2

Since I am unable to close my question, I will provide the answer here.

For those seeking something similar Dominic Elm from Thoughtram has created a fantastic example of using CDK's Overlay and Portals.

Instead of searching for a reference to the root component, I will dynamically append components to the application through this method.
