How to Retrieve the currentPageSlug in Sapper's template.html

When building applications using Sapper, a framework for Svelte, developers often run into the challenge of dynamically accessing certain page parameters, such as the current page's slug. This becomes particularly important when you want to customize elements in your template, such as images or metadata, based on the current page.

In this guide, we'll tackle this problem head-on, and I'll provide you with a straightforward solution to obtain the current page's slug in template.html. Let’s dive in!

The Challenge: Accessing the Page Slug

In your Sapper application, the basic template structure allows only specific tags, as shown below:

While this structure is essential for rendering static content, you may find it limiting when you need to adjust the content dynamically using page-specific data. For example, you might want to include something like the following in your template.html:

Simply put, you want to inject the current page’s slug into your HTML. The good news is that there is a way to retrieve this information without too much hassle!

The Solution: Using _layout.svelte

Instead of trying to extract the slug directly in template.html, you can leverage Sapper's layout component, specifically _layout.svelte. This file acts as a base for all pages in your application, giving you access to the page store.

Here’s how to do it:

Step 1: Importing Stores

In your _layout.svelte, you first need to import the necessary store from Sapper:

Optional: Adding Default Values or Conditions

If you want to be cautious and handle scenarios where there might not be a slug, you can add some simple conditions or default values:

Conclusion

By utilizing Sapper's reactive stores in the _layout.svelte file, you can efficiently access the current page's slug and integrate it smoothly into your templates. This method not only enhances your static site's functionality but also gives you the flexibility to handle different page scenarios.

Now, you can dynamically generate paths, SEO metadata, or even hidden elements based on the current page's context. Happy coding with Sapper, and may your applications be ever more dynamic and responsive!
