Is there a universal event that can be utilized for state change/start across all components, similar to the Component Lifecycle Hooks ? For example, in UI-router:

When considering your goals, you have the option to integrate the Router into your main component and use .subscribe() to access the state stream.
This approach was employed to create a feature that adjusts the browser's title based on the current state. In essence, it can be likened to the $stateChangeSuccess and $stateChangeFailure events found in Angular 1.
The actual code implementation would look like this:
constructor(router: Router) {
router.subscribe(successHandler, failureHandler);
}
Additionally, you may want to explore the OnActivate interface, which is closely tied to these concepts.
In order to utilize ui-router with Angular2, I have crafted the following code snippet to replace ng1 $rootScope $stateChangeSuccess:
import { Component } from '@angular/core';
import { TransitionService } from "ui-router-ng2";
@Component({selector: 'app-stage-tag',template: '...'})
class AppComponent {
constructor(public transitionService: TransitionService){
transitionService.onSuccess({to:'*'}, transition=>{
console.log('state', transition._targetState._definition)
console.log('params', transition._targetState._params)
})
}
}
