Troubleshooting Gatsby: Fixing Category Slugs Not Working from Dynamic Category Pages

If you're working with Gatsby and running into issues where clicking on a category from within a category page leads to incorrect URLs being generated, you're not alone. A common problem faced by many developers is the improper handling of slugs in dynamic category pages, causing URLs to concatenate and create unwanted paths. This guide will walk you through understanding the issue and how to solve it effectively.

Understanding the Issue

In your Gatsby setup, when you click on a category link from the category page, instead of navigating to a clean URL like /category/category-two, you might end up seeing something messy like /category/category-one/category-two. This confusion arises due to how slugs are formatted in your links. Let's break down this issue for clarity.

Dynamic Page Generation

In your gatsby-node.js, you are using GraphQL to create dynamic pages for both projects and categories. Here’s a simplified outline of how your code is structured for creating pages:

In this code, you've generated pages correctly. However, let's dive into the main issue – how the links are structured in your components.

The Solution

Ensuring Correct Link Paths

The primary culprit behind the inappropriate URL structure is the lack of an initial slash in the <Link> component used to navigate between categories. Here's how to correct this:

Make sure your link in CategoryPage.tsx is properly formatted with a leading slash:

Avoid the template literal formatting which can cause issues if slug does not already include a leading slash. Instead, simply use:

This adjustment guarantees that regardless of the content of slug, it will always begin a new path instead of appending to the current one.

Additional Notes

Check Your Structure: It’s good practice to understand how slugs are formatted. When generating slugs, especially from CMS content, they may or may not include leading slashes. Adjusting your link patterns accordingly will help help avoid similar pitfalls in the future.

Testing Links: Always check the resulting URLs in your development environment to ensure they match the expected format after making this change.

Conclusion

By ensuring that you include an initial slash in your category link paths, you can resolve the problematic URL concatenation issue in Gatsby. This not only enhances user navigation but also maintains a clean and organized URL structure across your application. If you run into further issues with dynamic pages or slugs, revisiting how you manage link formatting can often guide you to a resolution.

Ensuring a smooth site experience is a key aspect of web development—understanding these finer points can save you and your users time and frustration.
