Working with parameterized routes

In Blazor, parameterized routes allow you to pass parameters through the URL, making your application more dynamic and flexible. By leveraging route parameters, you can create components that respond to specific URL segments and render content based on those parameters. You can also use route parameters to persist the component state and allow users to bookmark it (which we explored at the beginning of Chapter 5).

Let’s extend component routing with parametrized routes, enforcing parameter constraints.

Getting ready

Before exploring parametrized routing, do the following:

• Create a Chapter09/Recipe02 directory – this will be your working directory
• Copy ExternalEventManager from the Chapter09/Recipe01 directory in the BlazorCookbook.Library project or the matching directory in the GitHub repository

How to do it…

Follow these steps to implement routes with parameters and intercept their values:
