Integrate service once the constructor has completed execution

Question

Integrate service once the constructor has completed execution

I created a service to connect with the Spotify API. When initializing this service in the constructor, it needs to retrieve the access token by subscribing to an Observable.

However, there's an issue:

The service is injected into my main component where I call its methods to fetch data from the Spotify API. I believe the problem lies in the fact that the access token has not been received before the initial request to the API attempts to use it.

Is there a way to ensure that the service is only injected after the constructor has successfully retrieved the access token?

Answer №1

If you're looking to access a service instance without it being injected through the constructor, you can use the injector.get method. Here's an example:

const notificationService = this.injector.get(NotificationService);
