Routing in angular by insert parameter in URL

Question

Suppose I have a component A which routes on localhost:4200/A I want to render A also when I pass parameters after A, like localhost:4200/A/xyz without any button click.

Simply if I hit the URL localhost:4200/A/xyz it should render component A here xyz is dynamic it may be changing.

You can add a route definition with a parameter like this:

{
        path: 'A/:id', component: AComponent
    },

Then in AComponent

import { ActivatedRoute } from '@angular/router';
@Component({
  selector: 'app-a',
  templateUrl: './a.component.html',
  styleUrls: ['./a.component.css']
})
export class AComponent{
  data: string;
  constructor(private activatedRoute: ActivatedRoute) {
     this.loadData();
  }

  loadData() {
    this.activatedRoute.paramMap.subscribe(params => {
      this.data= params.get('id');

    });
  }
