Original prompt

This section details on the original issue you should resolve

<issue_title>[Feature Request] Add the author element to the fulltext feed (when specified on the original feed)</issue_title>
<issue_description>Hello,

Using this script, I noticed the author of an article is not set on the fulltext feed, even if this information is on the original feed.
I would greatly appreciate to see this added, when it exists on the original feed, on a future release.

Here is the missing tag on an RSS feed :
<author>...</author>

Sometimes replaced with : <dc:creator>...</dc:creator>
The creator element is from the Dublin Core Metadata Initiative.
Here's the schema: https://dublincore.org/schemas/xmls/qdc/2008/02/11/dc.xsd
This element is seen all the time on feeds associated with WordPress blogs. It has become popular and generally preferred over the author element because the latter requires publishing an email address. The format for the creator element content is less restrictive and usually is just a name or username/handle.</issue_description>

Comments on the Issue (you are @copilot in this section)
@whtsky I'm not an RSS export and to be honest have no context on this field or the expected usage. would appreciate an PR for this @whtsky could you provide an test link for this? i could let copilot try working on this

Map item.creator from rss-parser (which captures both <author> and <dc:creator> elements) to the feed library's author format. For RSS2 output, post-process the XML to inject <dc:creator> elements since the feed library only outputs <author> when both email and name are present. The dc:creator element is widely used (especially by WordPress) and preferred over author as it doesn't require an email. For JSON Feed output, the author name is automatically included by the feed library. Also adds comprehensive unit tests for the new functionality.

@copilot this implementation feels too hack. if our current library don't support this, could you explore and find a library with good supporting on author & creator fields>

Replaced the feed library with feedsmith which has native support for Dublin Core namespace elements including dc:creator. The hacky XML post-processing in src/author.ts is now completely removed — feedsmith handles dc:creator natively via dc: { creator: '...' } on items, and automatically manages namespace declarations. See commit 4ca6317.

Switch from the `feed` library (which required hacky XML post-processing for dc:creator) to `feedsmith` which natively supports Dublin Core namespace elements including dc:creator. - Replace feed generation with feedsmith's generateRssFeed/generateJsonFeed - Map item.creator from rss-parser directly to dc.creator in feedsmith - Remove src/author.ts (no longer needed - no XML string manipulation) - Rewrite tests to verify feedsmith's native dc:creator output - Remove `feed` dependency, add `feedsmith` dependency Co-authored-by: whtsky <876694+whtsky@users.noreply.github.com>

Just as a heads up, I was blocked by some firewall rules while working on your feedback. Expand below for details.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

download.cypress.io
- Triggering command: /opt/hostedtoolcache/node/24.14.0/x64/bin/node /opt/hostedtoolcache/node/24.14.0/x64/bin/node index.js --exec install (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

Configure Actions setup steps to set up my environment, which run before the firewall is enabled

@copilot the project can't even build

feedsmith uses const type parameters (TS 5.0+) in its .d.cts files. Upgrade TypeScript from ^4.9.5 to ^5.0.0 and add skipLibCheck for @types/node compatibility. Co-authored-by: whtsky <876694+whtsky@users.noreply.github.com>

@copilot the project can't even build

Fixed in 5aef183. The build was failing because feedsmith uses TypeScript 5.0+ const type parameters in its .d.cts declaration files, but the project was on TypeScript 4.9.5. Upgraded TypeScript to ^5.0.0 and added skipLibCheck: true for @types/node compatibility. Build and all 9 tests pass now.

@copilot don't think this file should still exist

Deleted in 0d10fee. The file was testing feedsmith's API directly rather than our code.

tsconfig.json

    "esModuleInterop": true,
-    "allowSyntheticDefaultImports": true
+    "allowSyntheticDefaultImports": true,
+    "skipLibCheck": true


this is unacceptable. but you're welcome to upgrade the node version to 24 if @types/node is blocking in your way @copilot

Removed skipLibCheck: true and upgraded @types/node to ^22 instead, which resolves the TS 5 compatibility issue. See 0d10fee.

src/app.ts

-      newItem.content = content
-      return newItem

can we use ...item here?

Done in 0d10fee — now uses ...item spread with overrides for transformed fields (date, content, description).

same question, ...data?

Done in 0d10fee — both feedToRss and feedToJson now use ...data and ...item spreads with overrides for fields that need transformation.

@copilot let's be clear about the success criteria: we should be able to process:

without any issue, with full content retrieved, and essential fields kept. You can add an agnets.md to document this, and fix this PR

Gzip decompression is a transport-level concern, not application logic. Reverted to using rss-parser's built-in parseURL() instead of custom fetchUrl().

rss-parser already exposes `author` and `id` at runtime for Atom feeds. No customFields config needed — just the TypeScript generic type parameter to declare the properties that are already present.
