Creating a Dynamic Navbar in Hugo for User Authentication

When building a website, user experience is key, especially when it comes to authentication features like signing in and signing out. In Hugo, a static site generator, common practices for this include using fixed links for these actions in the navbar. However, static elements can feel impersonal and may confuse users who find themselves in different states of authentication.

In this guide, we will walk you through methods to create a dynamic navbar in Hugo that changes based on whether a user is signed in or signed out. This not only enhances user experience but also makes your site feel more interactive.

The Challenge

You may have already implemented authentication in your Hugo website, and now you're looking to improve the user interface by replacing the static Sign In and Sign Out buttons with a more dynamic solution. The objective is simple: display the correct button based on the user’s signed-in status.

The Solutions

Option 1: Using CSS Classes to Hide Elements

One straightforward method is to include both buttons in your navbar but use CSS to hide one based on the user's authentication status.

Step 1: Define CSS Class

Create a CSS class called .hidden to manage the visibility of the buttons:

Which Option Should You Choose?

CSS Method: This method is simpler to implement and requires less JavaScript. It keeps the markup minimal but may lead to unnecessary elements being present in the DOM.

Dynamic JS Method: This allows for a cleaner HTML structure and only shows relevant buttons based on user status but may be more complex to set up.

Conclusion

Creating a dynamic navbar for user authentication in your Hugo website can greatly improve user experience by adapting seamlessly to various states. Both solutions above offer practical ways to achieve this goal, depending on your preferences and requirements.

By implementing one of these methods, you’re on your way to providing an intuitive experience for users on your site. Happy coding!
