Sharing data with pre-loaded components in Angular 6

On my page, I have 3 main sections: the left component, the right component, and the header component. My goal is to update some data in the header component when the route changes from the left component. However, since the header component is already loaded, how can I access the data within it without using ngDocheck()?

Any advice would be greatly appreciated. Thank you in advance!

Answer №1

One way to handle router events is by subscribing to them using the following code:

ths.router.events.subscribe();

Another approach is utilizing a service with a proxy that gets triggered on route changes, like shown in this example:

export class MyService {
  dataToShare = new BehaviorSubject(undefined);
}
...
this.myService.dataToShare.subscribe();

There are various other methods available as well. The best practice would be to provide a Minimal, Complete and Verifiable Example within a sandbox so that the context can be understood and the answer adjusted accordingly.
