Navigating with Confidence: Fixing the NavLink Active Issue in React Router

When building web applications with React Router, developers often encounter cases where multiple navigational links can point to very similar URLs, especially when query parameters are involved. This can lead to confusion, particularly when tracking which link should appear as active based on user interactions. In this post, we'll explore a common scenario where you have multiple NavLink components, each linked to the same route but with different query parameters.

The Problem: Active Links Style Conflict

Imagine your application has a list of items, each represented by a unique identifier. As a developer, you want to ensure that only the link related to the clicked item is marked as active. Let's say you have the following structure for your items:

When rendering NavLink components for each item like so:

You may notice that all navigation items are highlighted as active, which isn't the intended behavior. Consequently, you want to display the active state only for the specific item that was clicked.

The Solution: Utilizing useLocation for Precise Active States

To solve this issue, we can take advantage of the useLocation hook provided by react-router-dom. This hook will help us obtain the current location object, allowing us to determine exactly which link should be displayed as active based on the URL.

Step-by-Step Implementation

Import the Hook:
First, make sure to import useLocation from react-router-dom in your NavigationItem component.

Access the Current Location:
Inside your NavigationItem component, retrieve the current location.

Compare the Current Path:
Modify the className of the NavLink to check if the current path matches the link's target. This will allow you to apply an active class conditionally.

Here's how your modified NavigationItem would look:

Explanation of the Code

Dynamic Class Assignment: The className of the NavLink changes dynamically based on whether it matches the current path. If it does, we append the active class; otherwise, it remains empty.

Conclusion

By implementing the useLocation hook correctly within your NavigationItem, you can ensure that your navigation links accurately reflect the user’s current location, improving the overall experience and clarity of your application. This simple yet effective solution allows you to handle cases where multiple links lead to similar destinations seamlessly.
