[angular] Router navigate relatively

we know this last post,

this.router.navigate(['/servers']);

this is absolute path. but funny thing is this code.

this.router.navigate(['servers']);

this looks like relative path. but it is not,

routerLink in html acts relatively with ['servers'] but navigate is not.

(do not wonder why. just it works like that.) 

if you want to navigate relatively use this.

this.router.navigate(['servers'], {relativeTo: this.route});

route can be declared by this.

constructor(private serversService: ServersService,

private router:Router,

private route:ActivatedRoute) { }
