This command successfully changes the path, but it unfortunately removes any query parameters. So, how can we effectively change the path while retaining those vital query parameters? In this guide, we’ll explore the solution.

Instead of manipulating the entire href, you should just update the pathname property of window.location. This method allows you to change the URL path while keeping the existing query parameters intact. Here’s how to do it:

Why This Works

Separation of Concerns: By modifying the pathname, you only affect the path component of the URL. The query component remains unchanged.

Efficient Navigation: This approach ensures that users can navigate smoothly without losing any data transmitted via URL parameters.

Step-by-Step Implementation

If you're ready to implement this solution, follow these straightforward steps:

Identify Your Current URL: Take note of the existing URL and its query parameters.

Use the Provided Code: Implement the code snippet to change the pathname at the desired point in your application:

Test Your Changes: After making the change, test to ensure the URL now reads as expected, with the query parameters remaining intact.

Conclusion

Changing a URL path without losing query parameters is essential for maintaining data integrity in web applications. By using the window.location.pathname method instead of changing the entire href, you can achieve this effortlessly. Remember, proper URL management is key when developing engaging web experiences!

Now you can navigate to your new URL path while seamlessly retaining any query parameters—keeping your application's functionality intact and user-friendly!
