how to add query parameter to url in angular

// Make sure to import and define the Angular Router and current Route in your constructor
constructor(
  private router: Router,
  private route: ActivatedRoute
) {}

...
...
...

// Take current queryParameters from the activated route snapshot
const urlParameters = Object.assign({}, this.route.snapshot.queryParams); 

// Need to delete a parameter ?
delete urlParameters.parameterName;

// Need to add or updated a parameter ?
urlParameters.parameterName = newValue;

// Update the URL with the Angular Router with your new parameters
this.router.navigate([], { relativeTo: this.route, queryParams: urlParameters });

export class ComponentA {

  // We need access to the Angular router object to navigate programatically
  constructor(private router: Router){}

  navigateWithArray(): void {
    // Create our query parameters object
    const queryParams: any = {};
    // Create our array of values we want to pass as a query parameter
    const arrayOfValues = ['a','b','c','d'];

    // Add the array of values to the query parameter as a JSON string
    queryParams.myArray = JSON.stringify(arrayOfVAlues);

    // Create our 'NaviationExtras' object which is expected by the Angular Router
    const navigationExtras: NavigationExtras = {
      queryParams
    };

    // Navigate to component B
    this.router.navigate(['/componentB'], navigationExtras);
