How to initialize a service eagerly?

Services (aka providers) are by default only initialized when they're being requested as a dependency.
If you want to dynamically add new providers, you can do that while processing a module:

class SomeModule extends createModule({}) {
  process() {
	if (someConstraint) {
  	  this.addProvider(SomeService);
	}
  }
}

If you mean with initialise that the service should just be instantiated, you should just register them on a onAppExecute or onServerBootstrap event.

class MyService {}


new App({
    providers: [MyService],
    listeners: [
        onAppExecute.listen((event, service: MyService) => {}),
    ]
}).run();

if it should initialize stuff async:

class MyService {
    async initialize() {
         // do some stuff
    }
}


new App({
    providers: [MyService],
    listeners: [
        onAppExecute.listen(async (event, service: MyService) => {
              await service.initialize();
        }),
    ]
}).run();
