src/lib/components/AnimatedCollapsibleContent.svelte (1)

1-32: Clean implementation of animated collapsible content.

This component effectively extends the bits-ui Collapsible.Content with smooth slide transitions and follows Svelte 5 patterns correctly.

Consider making the flex class configurable to increase component flexibility:

- <div {...props} transition:slide={{ duration, axis }} class="flex">
+ <div {...props} transition:slide={{ duration, axis }} class={`flex ${$$props.class || ''}`}>

Also, note that using forceMount always keeps the content in the DOM, which might impact performance for complex content. This is typically a reasonable tradeoff for smoother animations, but worth being aware of for future reference.

1-11: Consider using more specific content type for Atom feeds.

The implementation is clean and consistent with other feed endpoints.

For Atom feeds, the more specific MIME type application/atom+xml is widely recognized and preferred over generic application/xml:

  text(feed.atom1(), {
    headers: {
      "Cache-Control": "max-age=0, s-max-age=600",
-     "Content-Type": "application/xml"
+     "Content-Type": "application/atom+xml"
    }
  })

71-112: UI improvements look good, but check URL concatenation

The RSS feed selector UI is well-implemented with proper accessibility considerations and animations. However, there's a potential issue with the URL construction that could lead to malformed URLs.

The URL construction on line 105 might result in double slashes if the page URL already ends with a slash. Consider using a more robust URL joining approach:

-									href="{page.url}/{file}"
+									href="{page.url.endsWith('/') ? page.url + file : `${page.url}/${file}`}"

14-35: The base feed configuration looks good, but URL handling could be improved

The getBaseFeed function sets up a well-structured feed with all the necessary metadata. However, the URL manipulation for feed links is using regex replacement which might be fragile.

Consider using URL manipulation methods instead of regex for more robust URL handling:

-			xml: url.toString().replace(/[A-z\d]+\.[A-z\d]+$/, "rss.xml"),
-			json: url.toString().replace(/[A-z\d]+\.[A-z\d]+$/, "rss.json"),
-			atom: url.toString().replace(/[A-z\d]+\.[A-z\d]+$/, "atom.xml")
+			xml: new URL("rss.xml", url.origin + url.pathname.replace(/[^/]+$/, "")).toString(),
+			json: new URL("rss.json", url.origin + url.pathname.replace(/[^/]+$/, "")).toString(),
+			atom: new URL("atom.xml", url.origin + url.pathname.replace(/[^/]+$/, "")).toString()

42-46: Consider sanitization for Markdown content

While GitHub content might be trusted, it's generally a good practice to sanitize HTML output from markdown converters.

Even though you're handling GitHub content which is likely safe, it might be worth adding sanitization for extra security. The marked library has sanitization options that can be enabled.

-	// we'll assume GH content doesn't need to be sanitized *wink wink*
-	return marked(md) as string; // can only be a Promise if the `async` option is set to true, not the case here
+	// Enable sanitization for extra security
+	return marked(md, { sanitize: true }) as string; // can only be a Promise if the `async` option is set to true, not the case here

Or consider using DOMPurify as an additional layer:

import DOMPurify from 'dompurify';
// ...
return DOMPurify.sanitize(marked(md) as string);
