What is the best way to pass an array through router navigate function?

Question

What is the best way to pass an array through router navigate function?

I've searched for a solution in other questions, but nothing has helped me...

My goal is to redirect to a URL like this:

this.router.navigateByUrl('/products');

I want to pass an array and retrieve it in the component with the active link products using skip location change without displaying anything in the URL.

The array will look like this:

products = [{"id":1,"name":"Product One"},{"id":2,"name":"Product Three"},{"id":3,"name":"Product Six"}]

I need to pass this entire array in the router link and retrieve it in another component (products) with skipLocationChange set to true...

I tried using sharedService, but I encountered issues with data loading at the right time, which led me to decide to use a router link instead...

If you believe this approach isn't ideal, please suggest an alternative method that doesn't involve shared service...

When dealing with large datasets in Angular, utilizing Angular Services is a recommended approach.

import { Injectable } from '@angular/core';
import { Observable } from 'rxjs';
import { Subject } from 'rxjs/Subject';

@Injectable()
export class ExampleService {

private subject = new Subject<any>();  

updateRouteData(data) {
    this.subject.next(data);
}

routeData(): Observable<any> {
    return this.subject.asObservable();
}
}

To use these services within your components:

For setting route data:

import { ExampleService } from '/example.service'

export class ComponentOne{

constructor(private exampleService:ExampleService){
   this.exampleService.updateRouteData(data)
}

You can retrieve the data like so:

import { ExampleService } from '/example.service'

export class ComponentTwo{

constructor(private exampleService:ExampleService){
   this.exampleService.routeData().subscribe(data => {
       console.log(data)
   })
}
