Mastering Multiple Parameter Routing in Angular 11

In modern single-page applications, routing plays a pivotal role in seamlessly navigating between different components. One common requirement in Angular applications is the ability to pass multiple parameters through the URL. This guide will guide you through the process of correctly passing multiple parameters in your routing URLs using Angular 11.

Understanding the Issue

When trying to navigate to a route that requires parameters, it’s crucial to correctly format the URL. A user recently encountered a challenge while attempting to navigate to a specific route structured like this:

The goal was to create a URL that includes both the project model name and the sales pack. The initial attempt at navigating was as follows:

However, this resulted in a "page not found" error. Let’s break down the solution to overcome this issue.

The Correct Way to Pass Multiple Parameters

Avoid Unnecessary Slashes

The mistake in the initial attempt was the inclusion of unnecessary slashes in the navigation array. In Angular, when defining route parameters, the correct syntax should not include additional slashes at the beginning of the parameters being passed.

Instead of:

Retrieve Parameters in the Target Component:
In the target component (the one linked with salespack path), you can access the passed parameter as follows:

Key Takeaways

Always ensure that you format your routing navigation calls correctly by avoiding unnecessary slashes.

Use Angular's routing parameters to enhance the user interface by maintaining clean URLs while passing necessary data.

Conclusion

Navigating through multiple parameters in Angular 11 can be straightforward once you get used to the proper syntax. By following the tips outlined above, you can pass multiple parameters in your URLs effectively without running into issues like "page not found." Always make sure to retrieve and use these parameters in your target components to provide a seamless user experience.

Now that you're equipped with this knowledge, you can implement routing with multiple parameters elegantly in your Angular applications!
