Angular 4 router and modal dialog

Question

I have Angular 4 SPA application using Angular router. I want to have hyperlink that opens a component in new dialog using Bootstrap 4. I already know how to open modal dialog from a function.

But how to open it using hyperlink?

<a [routerLink]="['/login']">Login</a>

I want to leave my current component in and just show modal dialog in front of it.

Another question - is it possible to do that programatically? So that I can

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

and login modal dialog is displayed over current component?

Any suggestions?

My best guess is you may want to subscribe to the activated route and change params in the route to trigger the modal.

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

@Component({
  selector: 'cmp1',
  templateUrl: './cmp1.component.html',
  styleUrls: ['./cmp1.component.css'],
})
export class Cmp1 implements OnInit {

    constructor(private activatedRoute: ActivatedRoute) {
    }

    ngOnInit() {
        this.activatedRoute.params.subscribe(params => {
            if (params["modal"] == 'true') {
                // Launch Modal here
            }
        });
    }
}

I believe you would then have a link that looked something like this: <a [routerLink]="['/yourroute', {modal: 'true'}]">
