Understanding Routing in SvelteKit

If you’re working on a web application using SvelteKit and have encountered a frustrating 404 error while trying to access routes like domainname/about/about2, you’re not alone. Many developers face challenges understanding the routing system of SvelteKit, especially when it comes to organizing their folder structure for pages. In this guide, we'll break down the issue and provide a clear solution, enabling you to navigate SvelteKit's routing confidently.

The Problem: 404 Error in SvelteKit

When attempting to access a specific route, such as /about/about2, you might see a 404 error if your project structure is not aligned with SvelteKit's routing expectations. Based on the folder structure you've provided:

The key issue here stems from the way routing works in SvelteKit. Here's a deeper look into why you're facing this error.

The Solution: Embracing the New Routing Method

Transitioning to the New System

SvelteKit has evolved, and with the latest updates, it introduced a new routing strategy. Instead of the old method, you should now use + page.svelte to define pages. Here is how your project structure should look if you want to access the /about/about2 route successfully:

Explanation of the Changes

Replace index.svelte: The old system included files like index.svelte, which defined the primary route. However, in the new system, the path must be represented by + page.svelte.

Organizing Sub-routes:

To create a nested route like /about/about2, make sure to create a new folder named about2 inside the about directory.

Inside the about2 folder, add a + page.svelte file, representing the page that should render when visiting /about/about2.

Benefits of the New Routing System

Clear Structure: The hierarchy of routes is visually clear — you can easily understand which files correspond to which routes just by looking at the folder structure.

Scalability: It simplifies adding new routes as your application grows.

Future Compatibility: Aligning with the latest coding methodologies ensures that your project stays up-to-date with SvelteKit’s best practices.

Conclusion

By adjusting your routing structure as outlined above, you can resolve the 404 errors you’ve encountered and leverage SvelteKit’s powerful routing capabilities. Understanding how to properly organize your routes with + page.svelte will not only solve immediate problems but will also equip you with the skills to build scalable and maintainable applications with SvelteKit.

Now, go ahead and restructure your project accordingly. With this change, your application should be back on track and ready to serve pages without any more 404 hiccups!
