Query params

Query params are the most usual to work with within web development, they follow this pattern:


You can get them via an observable, within the ActivatedRoute, using the queryParams method.

success: string;

constructor(private route: ActivatedRoute) {
    this.route.queryParams.subscribe(params => {
        this.success = params["success"];

Path variables

Path variables are those that you create within your Angular application.


These can simply be accessed using the route’s snapshot method.

id: string;
constructor(private route: ActivatedRoute) { =;
