Navigating with Angular 4's router and popping up modals

I have an Angular 4 SPA application that utilizes the Angular router. I am looking to create a hyperlink that will open a component in a new dialog using Bootstrap 4. I am able to open modal dialogs from a function already.

My question is, how can I achieve this using a hyperlink?

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

The goal is to keep my current component visible and display the modal dialog on top of it.

Another point of interest - is there a way to accomplish this programmatically? For example,

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

Could this code snippet be used to display the login modal dialog over the current component?

Any suggestions or insights on how to achieve this would be greatly appreciated!

If you're looking to display a modal based on changes in the route, my suggestion would be to subscribe to the activated route and update the params accordingly.

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
            }
        });
    }
}

To trigger the modal, you can use a link like this:

<a [routerLink]="['/yourroute', {modal: 'true'}]">

If you prefer, you can also achieve the same result by using a path instead of a query parameter like the method described above. For a detailed explanation of both options, check out the following resource:

https://medium.com/ngconf/routing-to-angular-material-dialogs-c3fb7231c177

In summary:

First, create a simple component that automatically opens the modal when it is created:

@Component({
  template: ''
})
export class LoginEntryComponent {
  constructor(public dialog: MatDialog, private router: Router,
    private route: ActivatedRoute) {
    this.openDialog();
  }
  openDialog(): void {
    const dialogRef = this.dialog.open(LoginComponent);
    dialogRef.afterClosed().subscribe(result => {
      this.router.navigate(['../'], { relativeTo: this.route });
    });
  }
}

Next, integrate this new component into your routing configuration as follows:

RouterModule.forRoot([
{
  path: 'home',
  component: BackgroundComponentForModal,
  children: [
    {
      path: 'dialog',
      component: LoginEntryComponent
    }
  ]
},
{ path: '**', redirectTo: 'home' }

])

  ]
},
{ path: '**', redirectTo: 'home' }

])
