Angular ActivatedRoute data returns an empty object

I have a route registered with some data:

const routes: Routes = 
[
    {path: 'my-route', data: { title: 'MyTitle' }, component: MyComponent},
];

and I'm trying to access to the route's data using ActivatedRoute:

import { Component, OnInit } from '@angular/core';
import { ActivatedRoute } from '@angular/router';

@Component({...})
export class MyComponent implements OnInit {
  private routeData;

  constructor(private route: ActivatedRoute) {}

  ngOnInit() {
    this.routeData = this.route.data.subscribe((data) => {
      console.log(data); // this is returning an empty object {}
    });
  }
}

but for some reasons data is an empty object.

How to solve this problem?

Edit: the problem is that I was trying to access the ActivatedRoute from a Component which is outside the <router-outlet>. So it looks like that this is the intended behaviour.

However I still think that my answer below can be useful to anyone who is trying to accomplish the same thing.

I found a workaround on GitHub (thanks manklu) that I used in order to accomplish what I needed:

import { Component, OnInit } from '@angular/core';
import { Router, RoutesRecognized } from '@angular/router';

@Component({...})
export class MyComponent implements OnInit {
  private routeData;

  constructor(private router: Router) { }

  ngOnInit() {
    this.router.events.subscribe((data) => {
      if (data instanceof RoutesRecognized) {
        this.routeData = data.state.root.firstChild.data;
      }
    });
  }
}

doing this way this.routeData will hold the route data that I needed (in my case the page title).

Get route custom data for component outside <router-outlet> (Angular 8):

constructor(private router: Router) {}
    
ngOnInit() {
    this.router.events.subscribe(data => {
      if (data instanceof ActivationStart) {
        console.log(`Custom data`, data.snapshot.data);
      }
    });
  }

I Don't know the version spoken, but as of Angular 6, this worked for me:

(Ofcourse thanks to shinDath)

  routeData;
  ngOnInit() {
    //child route param doesnt go up to parent route params.
    this.router.events.subscribe((val) => {
      if (val instanceof ActivationEnd) {
        if(!$.isEmptyObject(val.snapshot.params)){
          this.routeData = val.snapshot.params;
        }
      }
    });
  }

This is part of my code (NOTE: I'm using Angular 8):

constructor(private _router: Router, private _route: ActivatedRoute) {}

ngOnInit() {
  ...
  this.listenRouting();
}

listenRouting() {
    this._router.events.subscribe((router: any) => {
      routerUrl = router.url;
      if (routerUrl && typeof routerUrl === 'string') {
        routerList = routerUrl.slice(1).split('/');
        console.log("data.breadcrumbs", this._route.snapshot.routeConfig.children.find(child => child.path === routerList[routerList.length - 1]).data.breadcrumbs);
        ...
      }
    });
}

So data is "hiding" under ActivatedRoute.snapshot.routeConfig.children Array. Each child contains, among other things, data. In my case data is configured in routing.module, e.g.:

const routes: Routes = [
  { path: "facility-datas",
    component: FacilityTerminal,
    data: {
      breadcrumbs: "b ft"
    }
  },
...
];

This worked for me. Also kept getting an empty object until I did this.

constructor(private route: ActivatedRoute) { 
    this.route.data.subscribe(data => {
        console.log(data);
    })
}

Answer from Angular contributor, link

this.router.events.pipe(
    filter((e) => e instanceof NavigationEnd),
    map(() => {
        let route = this.activatedRoute;

        while (route.firstChild) {
            route = route.firstChild;
        }

        return route;
    }),
    filter((route) => route.outlet === 'primary'),
    mergeMap((route) => route.data),
    tap(console.log)
);

constructor(
    private router: Router,
    private activatedRoute: ActivatedRoute,
) {}

import { AfterViewInit, Component} from '@angular/core';
import { ActivatedRoute } from '@angular/router';


@Component({
  selector: 'app-users',
  templateUrl: './users.component.html',
  styleUrls: ['./users.component.scss']
})
export class UsersComponent implements AfterViewInit {
  paramId: string;

  constructor(private activatedRoute: ActivatedRoute) {}

  ngAfterViewInit(): void {
    this.paramId = this.activatedRoute.snapshot.params.id;
    console.log('paramId =', this.paramId);
  }

}

Below should work:

constructor(private route: ActivatedRoute) {}

ngOnInit() {
	console.log(this.route.snapshot.data);
}
