How do I pass data to Angular routed components?

In one of my Angular 2 routes’s templates (FirstComponent) I have a button

first.component.html

<div class="button" click="routeWithData()">Pass data and route</div>

My goal is to achieve:

Button click -> route to another component while preserving data and without using the other component as a directive.

This is what I tried…

1ST APPROACH

In the same view I am storing collecting same data based on user interaction.

first.component.ts

export class FirstComponent {
     constructor(private _router: Router) { }

     property1: number;
     property2: string;
     property3: TypeXY; // this a class, not a primitive type

    // here some class methods set the properties above

    // DOM events
    routeWithData(){
         // here route
    }
}

Normally I’d route to SecondComponent by

 this._router.navigate(['SecondComponent']);

eventually passing the data by

 this._router.navigate(['SecondComponent', {p1: this.property1, p2: property2 }]);

whereas the definition of the link with parameters would be

@RouteConfig([
      // ...
      { path: '/SecondComponent/:p1:p2', name: 'SecondComponent', component: SecondComponent} 
)]

The issue with this approach is that I guess I can’t pass complex data (e.g. an object like property3) in-url;

2ND APPROACH

An alternative would be including SecondComponent as directive in FirstComponent.

  <SecondComponent [p3]="property3"></SecondComponent>

However I want to route to that component, not include it!

3RD APPROACH

The most viable solution I see here would be to use a Service (e.g. FirstComponentService) to

• store the data (_firstComponentService.storeData()) on routeWithData() in FirstComponent
• retrieve the data (_firstComponentService.retrieveData()) in ngOnInit() in SecondComponent

While this approach seems perfectly viable, I wonder whether this is the easiest / most elegant way to achieve the goal.

In general I’d like to know whether I’m missing other potential approaches to pass the data between components, particularly with the less possible amount of code
