Script Not Loaded Initially if Inside & Outside of AlpineJS x-if

In this article, we will delve into a peculiar issue that has been observed in Astro v5, specifically when using AlpineJS with the x-if directive. The problem arises when a component's script is not loaded initially, both when it is inside an AlpineJS conditional statement and when it is not. This issue has been reported to occur across all browsers, making it a cross-browser compatibility problem. In this article, we will explore the details of this issue, provide a minimal reproducible example, and discuss possible solutions.

Before we dive into the issue, let's take a look at the Astro environment in which this problem occurs.

Astro Info

Astro                    v5.4.2
Node                     v20.18.0
System                   Linux (x64)
Package Manager          npm
Output                   server
Adapter                  @astrojs/node
Integrations             @astrojs/alpinejs
                         @astrojs/tailwind

As we can see, the Astro version is v5.4.2, and the Node version is v20.18.0. The system is running on Linux (x64), and the package manager is npm. The output is set to server, and the adapter is @astrojs/node. Additionally, the integrations include @astrojs/alpinejs and @astrojs/tailwind.

The issue is not limited to a specific browser, but rather affects all browsers.

If this issue only occurs in one browser, which browser is a problem?

All

This indicates that the problem is not browser-specific, but rather a general issue that affects all browsers.

When a component is included inside an AlpineJS x-if directive, and another component is included independently of any AlpineJS logic, the component's script is not loaded initially. However, when the component inside the x-if directive becomes visible, the script is executed as well.

Describe the Bug

When I include an Astro component inside an alpinejs x-if and another one independend of any alpinejs logic, the components <script> is not included/executed. Only when the one inside x-if becomes visible, the script gets executed as well. This first started happening after migrating to astro v5.

This description highlights the issue, which is that the script is not loaded initially, both when the component is inside the x-if directive and when it is not.

The expected result is that the script should be included as soon as the component is rendered, independently of any other conditional logic.

What's the expected result?

The script should be included as soon as the component is rendered, independend of any other conditional logic.
