Introduction

If you're working with Angular, you may have come across a scenario where certain child routes are accessible without their corresponding parent route. This issue can be particularly confusing and may lead to unexpected behavior in your application. In this post, we'll delve into a common problem encountered in an Angular application and provide a clear and effective solution to rectify it.

The Problem

In an Angular 13 application, the routing setup may encounter difficulties if the child routes are not properly organized. For instance, you might find that both URLs:

https://localhost:4200/store/dashboard

https://localhost:4200/dashboard

successfully load the same DashboardComponent, despite the expectation that the second URL should not be valid. This can create confusion and potentially cause issues with your application routing.

Understanding the Routing Setup

To understand the issue, let’s briefly review the routing configuration:

Child Module Declaration

The child module is defined as follows:

Lazy Loading Parent Module

The parent module lazy loads the child module like this:

Why Does This Happen?

The issue arises because the StoreModule was declared in both the app’s root module (app.module.ts) and lazy-loaded. This dual declaration inadvertently creates access for the child routes both as direct children and also under the lazy-loaded parent.

The Solution

The solution to rectify this routing issue is straightforward:

Remove the Declaration of StoreModule: Ensure that you remove the StoreModule from the imports list in your app.module.ts. This will prevent Angular from recognizing it as both a lazy-loaded module and as a direct path from the root module.

Code Correction

Here’s how you would revise your app.module.ts:

After Correction: Just include the router imports as follows:

Conclusion

By following the steps outlined above, you can prevent child routes in Angular from being accessed without their corresponding parent routes. This not only maintains the integrity of your application's routing but also ensures a smoother user experience.

Hopefully, this guide helps anyone facing similar routing issues in their Angular applications. Remember, a well-structured routing system is crucial for managing components effectively within your application!
