Mastering Angular Navigation: Keeping Your Button Active on the Exact Route

When developing an Angular application, maintaining the visual state of your navigation can be crucial for user experience. In particular, you may find yourself needing to highlight buttons based on the current route. However, what happens when your button remains highlighted beyond the desired path? This is a common dilemma faced by many developers. Let's explore one such case and a solution to rectify it.

The Dilemma: Overactive Navigation Button

Imagine you're working on a navigation bar with buttons that should indicate the active route. Here’s the scenario: you have a button that should light up only when the user is on the exact /system route. However, it currently highlights as soon as the path matches /system/something, which is not ideal for your application’s UX. Here’s a look at your existing code:

Current Functionality

The button retains the footer-btn-active class on any route that begins with /system, like /system/details or /system/settings.

This behavior can confuse users as it might imply that they are on the /system route when they aren't.

The Solution: Using routerLinkActiveOptions

To fix this issue, we can adjust the routerLinkActive directive by adding routerLinkActiveOptions. This addition allows us to specify that the class should only activate when the path matches exactly. Here’s how to do it:

Breakdown of the Changes

[routerLinkActiveOptions]:

This new property lets you specify additional options for the routerLinkActive directive.

Setting exact: true:

By setting this option to true, the button will only receive the footer-btn-active class when the route is exactly /system. It won’t apply the active class for subpaths like /system/....

Benefits of This Approach

Clear Visual Feedback: Users will clearly see when they are on the /system page without the distraction of an active button on related routes.

Improved User Navigation: This precise control over the button's active state enhances overall navigation clarity.

Conclusion

In summary, controlling the active state of navigation buttons in your Angular application can significantly enhance user experience. By utilizing the routerLinkActiveOptions with exact: true, you ensure that buttons reflect the correct state based on the exact current route. Implementing this change is straightforward, and it can lead to a more user-friendly application.

Now, go ahead and make these adjustments to your navigation bar and enjoy a cleaner and more intuitive interface!
