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?


Solution

  • 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).
