Navigating in Angular with parameters without modifying the URL address

Question

Navigating in Angular with parameters without modifying the URL address

In a nutshell, my goal is to navigate to a page with parameters without showing them in the URL. I have two components: Component A and B. What I want to do is route to B while still needing some parameters from A. I know I can achieve this by setting a route like [/B:parameter]. The issue is that it alters the URL from localhost:4200/b to something like localhost:4200/b=?parameter. I want to keep the parameters hidden from users because: - It's not relevant to them - It may involve sensitive business logic or data. Currently, I am using a constant to store the necessary state and accessing it in B's onInit method. Although this method works effectively, I find it inelegant. There must be a better and more sophisticated approach to handle this situation. It functions well enough, but it doesn't sit right with me. How can I tackle this elegantly?

Quick tip: Transmitting information through routes during navigation.

Insight: The data parameter can be located in the Route documentation (https://angular.io/api/router/Route)

Illustration: Within the routing module:

path: 'auth', component: AuthComponent, data: { type: 'admin' }

In the AuthComponent, you can retrieve the type data using ActivatedRoute

  constructor(
    private activatedRoute: ActivatedRoute
  ) {
    this.type = this.activatedRoute.snapshot.data.type;
  }
