Walkthrough

The RSS generation function in apps/blog/src/lib/rss.ts has been modified to sort blog pages by date in descending chronological order (newest first) before generating the feed. Previously, pages were passed unsorted to the RSS generation logic.

Changes

Cohort / File(s)	Summary
RSS Feed Sorting apps/blog/src/lib/rss.ts	Modified getRSS() to copy and sort blog.getPages() results by data.date in descending order before passing to generateRSS. Maintains consistent function signature and metadata construction logic.

7-10: Good fix for RSS feed ordering.

The sorting logic correctly orders posts by date descending (newest first), which is the expected convention for RSS feeds. Using the spread operator to copy the array before sorting is the right call—Array.prototype.sort() mutates in place, and you don't want to affect the original blog.getPages() result elsewhere.

One small observation: since the Zod schema uses z.coerce.date() (see apps/blog/source.config.ts:22), page.data.date is already a Date object. Wrapping it in new Date() again is technically redundant—though it's harmless and acts as defensive coding. The same pattern appears on line 23.

If you wanted to tighten this up:

♻️ Optional: Remove redundant Date wrapping

 const pages = [...blog.getPages()].sort(
   (a, b) =>
-    new Date(b.data.date).getTime() - new Date(a.data.date).getTime(),
+    b.data.date.getTime() - a.data.date.getTime(),
 );

And on line 23:

-    const date = new Date(page.data.date);
+    const date = page.data.date;

That said, the current implementation is perfectly functional and achieves the goal.

while preserving descending date order.
