Clicking on an Angular routerLink that points to the current route does not function unless the page is re

Currently, I am working on an E-commerce project. In the shop page, when a user clicks on the "View More" button for a product, I redirect them to the product details page with the specific product id.

<a [routerLink]="['/product-details', product.id]">View More</a>

Once the user is on the product page, I want to display 4 additional products from the same brand below the product details. To achieve this, I have created an API that takes the brand_id of the current product and returns 4 random products for that brand. When the user clicks on one of these additional products, they should stay on the same page but with the new product's details like this:

<a [routerLink]="['/product-details', moreProduct.id]">View More</a>

The issue I am facing is that although the URL updates with the new product id, the content on the page does not change until I manually reload the page. How can I resolve this problem?

Implementing the Angular component with route params that can change within the component itself requires moving any logic dependent on the route params to be executed within the subscribe method of ActivatedRoute.paramMap observable. This ensures that the logic is triggered every time the params are updated.

Here's an example:

constructor(private activatedRoute: ActivatedRoute, ....) {}

ngOnInit(): void {
  this.activatedRoute.paramMap
    .subscribe((params) => {
      const productId = params.get('PRODUCT_ID_PARAM_NAME');
      // Implement logic related to products here or any other logic depending on the params
    });
}

To ensure that Angular does not reuse the component and recreates it instead, include the following code snippet in your constructor:

this.router.routeReuseStrategy.shouldReuseRoute = function () {
       return false;
    };
