Angular 6 - Get current route and its data - angular6

Question

How to get the current route you're in and its data, children and parent?
If this is the route structure:
const routes: Routes = [
{path: 'home', component: HomeComponent, data: {title: 'Home'}},
{
path: 'about',
component: AboutComponent,
data: {title: 'About'},
children: [
{
path: 'company',
component: 'CompanyComponent',
data: {title: 'Company'}
},
{
path: 'mission',
component: 'MissionComponent',
data: {title: 'Mission'}
},
...
]
},
...
]
If I am currently in CompanyComponent, how do I get my current route w/c is Company, get its parent w/c is about, its data and its siblings such as mission, etc.?

Answer 1

#Component({...})
export class CompanyComponent implements OnInit {
constructor(
private router: Router,
private route: ActivatedRoute
) {}
ngOnInit() {
// Parent: about
this.route.parent.url.subscribe(url => console.log(url[0].path));
// Current Path: company
this.route.url.subscribe(url => console.log(url[0].path));
// Data: { title: 'Company' }
this.route.data.subscribe(data => console.log(data));
// Siblings
console.log(this.router.config);
}
}

constructor(
private router: Router,
private route: ActivatedRoute,
) {
}
ngOnInit() {
this.router.events.pipe(
filter(event => event instanceof NavigationEnd),
map(() => {
return this.getHeaderClasses();
}),
)
.subscribe((headerClasses: string | null) => {
this.headerClasses = headerClasses;
});
this.headerClasses = this.getHeaderClasses();
}
getHeaderClasses(): string | null {
let child = this.route.firstChild;
while (child) {
if (child.firstChild) {
child = child.firstChild;
} else if (child.snapshot.data && child.snapshot.data['headerClasses']) {
return child.snapshot.data['headerClasses'];
} else {
return null;
}
}
return null;
}
routing
{
path: 'list',
component: DialogListComponent,
data: {
headerClasses: 'col-lg-8',
},
},

Answer 3

You can access the route's data property from the snapshot like this:
import { Component, OnInit } from '#angular/core';
import { ActivatedRoute } from '#angular/router';
#Component({
templateUrl: './app/home/welcome.component.html'
})
export class WelcomeComponent implements OnInit {
public pageTitle: string;
constructor( private route: ActivatedRoute) {
}
ngOnInit(): void {
this.pageTitle = this.route.snapshot.data['title'];
}
}

Answer 4

#Component({...})
#UntilDestroy()
export class CompanyComponent implements OnInit {
constructor(private router: Router) {}
ngOnInit() {
this.router.events
.pipe(
untilDestroyed(this),
filter((event): event is NavigationEnd => event instanceof NavigationEnd),
map((event: NavigationEnd) => event.url)
)
.subscribe(url=> {
console.log(url);
});
}
}
