How do I defer the @astro/prefetch integration's script tag, which is inserted into HTML

[minor ridge]

This is the format of the script tag that the integration adds: <script type="module" src="/_astro/page.816b6a16.js"></script>

where 816b6a16 is a unique identifier.

Is there a way I can add defer attribute to this tag by overriding the plugin's injectScript invocation?

Hi @minor ridge. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

Based on the information provided in the extracts, there is no direct mention of adding a defer attribute to the script tag via the injectScript function in Astro's Integration API. The injectScript function allows you to inject a string of JavaScript content onto every page, but it doesn't specify the ability to modify the attributes of the script tag itself.

Here is how the injectScript function is used:

injectScript('page-ssr', 'import "global-styles.css";');

The stage parameter denotes how the script (the content) should be inserted. Some stages allow inserting scripts without modification, while others allow optimization during Vite’s bundling step. However, none of these stages mention the ability to add a defer attribute.

For more details, you can refer to the Astro Integration API documentation (https://docs.astro.build/en/reference/integrations-reference).

If you need to add the defer attribute to your script tags, you might need to do it manually in your HTML or explore other options within the Astro framework or Vite's plugin ecosystem.

@raven sleet Any way I can tap into vite's bundling step to add an attribute to a tag?

Let me check the knowledge base for you. One moment! :books:

Based on the provided extracts, there isn't a direct way mentioned to tap into Vite's bundling step to add an attribute to a tag. The extracts discuss how to pass additional configuration options to Vite through the Astro configuration file, but they don't specify how to modify attributes of tags during the bundling process.

Here's an example of how to pass additional configuration options to Vite:

{
 vite: {
 ssr: {
 // Example: Force a broken package to skip SSR processing, if needed
 external: ['broken-npm-package'],
 }
 }
}

For more advanced configurations, you might need to refer to the full Vite configuration documentation on vitejs.dev (https://vitejs.dev/config/).

If you need to add an attribute to a tag during the bundling process, you might need to explore other options within the Vite plugin ecosystem or seek help from the Vite community.

Is there a way I can change this to accept an attribute to attach:

        injectScript: (stage, content) => {
          updatedSettings.scripts.push({ stage, content });
        },

This is from astro's integration file: node_modules/astro/dist/integrations/index.js

Based on the provided extracts, there isn't a direct way to modify the injectScript function to accept an attribute. The injectScript function in the Astro Integration API is designed to accept two parameters: stage and content.

Here's how it's currently used:

injectScript('page-ssr', 'import "global-styles.css";');

The stage parameter denotes how the script (the content) should be inserted. However, there's no mention of a way to pass an attribute to this function.

If you need to modify the injectScript function to accept an attribute, you might need to modify the Astro source code itself, which is not recommended as it could lead to unexpected behavior and compatibility issues with future updates of Astro.

For more details, you can refer to the Astro Integration API documentation (https://docs.astro.build/en/reference/integrations-reference). If you need further assistance, consider reaching out to the Astro community or the maintainers of the Astro project.
