test/e2e/feeds.spec.ts (1)
20-49: Test is mostly solid; a couple of small robustness nits.
expect(href.slice(0, 16)).toBe('https://npmx.dev')is correct arithmetic ('https://npmx.dev'.length === 16) but brittle — any host-name change silently breaks both the prefix check and the derivedurl = href.slice(16). Prefer matching on the parsed URL so intent is obvious and the "derive path from href" step can't go wrong:- // href is an absolute link - expect(href.slice(0, 16)).toBe('https://npmx.dev') - - const { contentType, corsHeader } = await page.evaluate(async href => { - // Fetch the same path as in the alternate link - const url = href.slice(16) - const response = await fetch(url) + // href must be an absolute URL on the production origin + const parsed = new URL(href) + expect(parsed.origin).toBe('https://npmx.dev') + + const { contentType, corsHeader } = await page.evaluate(async path => { + const response = await fetch(path) return { contentType: response.headers.get('Content-Type'), corsHeader: response.headers.get('Access-Control-Allow-Origin'), } - }, href) + }, parsed.pathname)
await expect(locator).toHaveAttribute('href')without a second argument checks existence (fine), and the subsequentgetAttribute('href')+expect(href).not.toBeNull()+typeof href !== 'string'guard is a bit redundant. You can drop the first assertion and keep the null/string guard, sinceexpect(href).not.toBeNull()already fails the test on absence.Minor:
response.headers.get('Content-Type')returns the full header value, which may include charset parameters (application/rss+xml; charset=utf-8) depending on the server. Right nowtoBe(feed.contentType)would break if Nitro ever adds a charset. Considerexpect(contentType).toMatch(new RegExp('^' + feed.contentType))to be forward-compatible.🤖 Prompt for AI Agents
Verify each finding against the current code and only fix it if needed.

195-206: CORS + Content-Type via route rules — looks good.Matches the PR checklist (enable CORS, serve correct MIME types) and the values are exactly what
test/e2e/feeds.spec.tsasserts. One small thought: if you want feeds to be cacheable by intermediaries, consider adding aCache-Control: public, max-age=…header alongside — otherwise feed aggregators may hit the origin more often than needed.🤖 Prompt for AI Agents

19-40: Remove hard-coded feed URLs and title; use root-relative hrefs or derive from site config.The three hard-coded
https://npmx.dev/*hrefs and the fixed'Blog - npmx'title duplicate values already present innuxt.config.ts(site.url,site.name) and inserver/utils/feeds.ts. If the canonical origin ever changes (staging, preview branches, a rename), these links will silently point at the wrong host. Also note these are already absolute on a blog page onnpmx.dev— a root-relativehref(/rss.xml, etc.) is equally valid for<link rel="alternate">and would avoid hard-coding the origin on the client.Consider either:
Option A — root-relative hrefs
- href: 'https://npmx.dev/rss.xml', + href: '/rss.xml', ... - href: 'https://npmx.dev/atom.xml', + href: '/atom.xml', ... - href: 'https://npmx.dev/feed.json', + href: '/feed.json',Option B — derive from site config
const siteConfig = useSiteConfig() const origin = siteConfig.url // 'https://npmx.dev' useHead({ link: [ { rel: 'alternate', title: `${siteConfig.name} Blog`, type: 'application/rss+xml', href: `${origin}/rss.xml` }, { rel: 'alternate', title: `${siteConfig.name} Blog`, type: 'application/atom+xml', href: `${origin}/atom.xml` }, { rel: 'alternate', title: `${siteConfig.name} Blog`, type: 'application/feed+json', href: `${origin}/feed.json` }, ], })Note:

In `@nuxt.config.ts`:
- Around line 243-251: The esbuild exclude regex under the esbuild options
currently targets node_modules/.cache/nuxt/.nuxt/blog/posts.ts which won't match
Nuxt's actual buildDir (e.g. .nuxt/blog/posts.ts); update the exclude pattern in
the esbuild.options.exclude to allow the generated .nuxt/blog/posts.ts (or
otherwise include .nuxt/**/blog/posts.ts) so the `#blog/posts` import isn't
excluded, and add a simple runtime/build-time assertion or log of the resolved
buildDir used by Nuxt (referenced from server/utils/feeds.ts) to surface
mismatches early; also fix the comment path to use forward slashes
(server/utils/feeds.ts) for consistency.
In `@package.json`:
- Line 136: Move the "feed" package from devDependencies to dependencies in
package.json so it is available at runtime; update package.json by removing
"feed": "5.2.0" from devDependencies and adding the same entry under
dependencies. This ensures imports in server/utils/feeds.ts (used by the
/rss.xml, /atom.xml and /feed.json routes with prerender: true) are present in
production builds and prevents runtime errors if those routes are ever rendered
on-demand.
In `@server/utils/feeds.ts`:
- Around line 4-17: Add a short clarifying comment above the module-level
variable "feed" explaining that this cache is build-time only because getFeed()
calls generateFeed() once at module import (used for prerendered /rss.xml,
/atom.xml, /feed.json), and that if prerendering/ISR is removed the cache will
become stale and must be invalidated or regenerated (e.g., reset feed or call
generateFeed on each request); reference the "feed" variable, the getFeed()
function and generateFeed() to make the intended lifetime and required
invalidation explicit for future maintainers.
- Around line 19-54: generateFeed currently passes post.image through unchanged
causing broken thumbnails; update the feed.addItem call in function generateFeed
to normalize post.image the same way author.avatar is normalized (e.g., if
post.image exists, set image to new URL(post.image, siteUrl).toString()), and
replace the hard-coded title/description/id/link values with values pulled from
the shared site config (useSiteConfig() or equivalent) so title/description/site
URL are derived from the single source of truth used by nuxt.config.ts and
app/pages/blog/index.vue.

Nitpick comments:
In `@app/pages/blog/index.vue`:
- Around line 19-40: Replace the hard-coded feed hrefs and title in the useHead
call with either root-relative paths or values derived from the site's config:
stop using 'https://npmx.dev/*' and the fixed 'Blog - npmx' string in the link
array inside useHead; instead call useSiteConfig() (already used elsewhere),
read siteConfig.url (if you need absolute origin) and siteConfig.name (for the
title), and set hrefs to '/rss.xml', '/atom.xml', '/feed.json' or to
`${siteConfig.url}/rss.xml` etc., and set title to `${siteConfig.name} Blog`;
update the same pattern in server/utils/feeds.ts as well for consistency.
In `@nuxt.config.ts`:
- Around line 195-206: The route rules for '/rss.xml', '/atom.xml', and
'/feed.json' currently set CORS and Content-Type but lack caching; update the
headers object in nuxt.config.ts for the route keys '/rss.xml', '/atom.xml', and

max-age=3600') so intermediaries can cache feeds; modify the headers for the
RouteRule entries (the objects used for these paths) accordingly and run/update
any tests that assert exact header sets if needed.
In `@test/e2e/feeds.spec.ts`:
- Around line 20-49: The test should parse the alternate link href with the URL
API instead of slicing and remove the redundant locator existence assert; change
the code to getAttribute('href') into href, guard for null/string, then create
const parsed = new URL(href) and assert parsed.origin === 'https://npmx.dev' (or
the intended host) and pass parsed.pathname+parsed.search into page.evaluate for
fetching; finally relax the content-type check to match the media type prefix
(e.g., use a startsWith or regex like '^' + feed.contentType) when asserting
response.headers.get('Content-Type') so charset parameters won't break the test
— update references: locator, href, page.evaluate, response.headers.get and the
expect(contentType) assertion accordingly.

Huh, yeah, that's weird. Well, JSON feed is still definitely niche, but for what it's worth, I found out that Declan Childlow also uses it. I opened a PR to add version 1.1 support in the upstream
I think either makes sense, honestly. https://npmx.dev/rss.xml right now redirects to https://npmx.dev/package/rss.xml, but I wouldn't call that a conflict if that redirect gets replaced with the feed. Out of the sites with feeds that come to mind, MDN seems the most similar to npmx in that they have a blog with a feed, but it's by no means the main reason people visit the site.

Thank you very much for opening the PR, @Kiwow! Sorry that it has been a long wait since the last activity here, but we would be interested in getting this PR ready to be released. Two cents from my sides after quickly reading through the discussion in here:
Other than that, it would be lovely if you could update the branch and resolve the merge conflicts! Looking forward to getting this merged 🚀 |

Hi there @trueberryless Sounds good! I’ll move those routes under /blog and remove the JSON feed altogether. I should have some time this week to get that sorted. It’s a shame the PR in the Thank you and @ghostdevv both for the feedback on here, it’s been a pleasure 🙏 |

Issues / obstacles:
The feed package currently doesn't support JSON Feed 1.1, which added support for multiple authors. This means it silently throws away all but the first author we specify in an the
authorarray. Manually parsing the object after it gets generated and adding in the other authors is an option, but then we'd be lying about the version that we're serving. Alternatively, it shouldn't be that hard to write the JSON Feed serializer ourselves (thefeedimplementation is a bit over 100 lines of code)RSS (the spec) seemingly doesn't support multiple authors at all, or just in convention, where you put everyone into an
<author>tag. I'll have to try and test some readers / find how feeds handle multiple authors to figure out a good solution. Either way, thefeedpackage includes multiple<author>tags, which seems to be valid in Atom but not in RSS.Also see my update comment on this
