Passing dynamic data through Angular 2 route

You can use a resolver. The data returned by a resolver is made available to routes the same way static data on route configurations is

For an example see https://angular.io/guide/router#resolve-guard

@Injectable()
export class CrisisDetailResolve implements Resolve<Crisis> {
  constructor(private cs: CrisisService, private router: Router) {}
  resolve(route: ActivatedRouteSnapshot): Promise<Crisis>|boolean {
    let id = route.params['id'];
    return this.cs.getCrisis(id).then(crisis => {
      if (crisis) {
        return crisis;
      } else { // id not found
        this.router.navigate(['/crisis-center']);
        return false;
      }
    });
  }
}

path: '',
component: CrisisListComponent,
children: [
  {
    path: ':id',
    component: CrisisDetailComponent,
    canDeactivate: [CanDeactivateGuard],
    resolve: {
      crisis: CrisisDetailResolve
    }
  },

ngOnInit() {
  this.route.data
    .subscribe((data: { crisis: Crisis }) => {
      this.editName = data.crisis.name;
      this.crisis = data.crisis;
    });
}

You can do two things 1.Not recommended but use data as router parameter and pass,

{ path: 'some:data', component: SomeComonent }

and use as

let data = {"key":"value"}
this.router.navigate(['/some', data)

2.Instead of passing data through route params(because data may be huge and also vulnerable to attack since it can be viwed by the user)

@Injectable()
export class SomeService {
  data = {};
}

@Component({...
   providers: [SomeService]
export class Parent {
  constructor(private someService:SomeService) {}

  private click() {
    this.someService.data = {"key":"value"}
  }
}
