Feed — /feed (HTML) and /feed.xml (RSS)

The feed has two sibling surfaces. /feed is a human-readable stream of recent blog posts and knowledge-base entries with previews. /feed.xml is a valid RSS 2.0 file that any RSS reader can subscribe to. They share the same source data; they differ in audience.

TL;DR — /feed for humans (cards, summaries). /feed.xml for RSS readers (Feedly, Inoreader, NewsBlur, FreshRSS). Both auto-update every build.

What is in the feed​

Both surfaces include:

  • Blog posts with a publish date in the last 90 days.
  • Knowledge-base entries with a publish or refresh date in the last 90 days.

Older items are excluded by default (the /blog and /learn indexes are the canonical browse surfaces for older content). The cap on 90 days keeps the feed focused on recency.

/feed (the HTML page)​

A single page rendering the recent items as cards:

  • Title (English + Urdu).
  • Publish or update date.
  • 1-2 sentence excerpt.
  • Type badge (Blog / Knowledge / Changelog).
  • Click to open the full entry.

Sorted reverse-chronological. Latest at the top.

The page also has prominent links to /feed.xml (the RSS counterpart) at both the top and bottom.

/feed.xml (the RSS counterpart)​

A standards-compliant RSS 2.0 file. The structure:

<?xml version="1.0" encoding="UTF-8"?>
<rss version="2.0" xmlns:atom="http://www.w3.org/2005/Atom">
  <channel>

    <atom:link href="https://imtehanhub.aoneahsan.com/feed.xml"

The feed includes:

  • <atom:link rel="self"> (validates against W3C RSS validator).
  • <lastBuildDate> updated each build.
  • <category> per item.
  • Absolute URLs for <link> and <guid>.

How to subscribe in an RSS reader​

Add the URL https://imtehanhub.aoneahsan.com/feed.xml to any RSS reader. Tested combinations:

ReaderURL pattern
Feedly"+ Add Content" → paste the URL
Inoreader"Add subscription" → paste
NewsBlur"Add Site" → paste
FreshRSS"Subscriptions" → "Add" → paste
Thunderbird"Subscribe" → "Add" → paste

Most readers refresh feeds every 1-3 hours. ImtehanHub's feed updates on every site deploy.

How the feed is generated​

A build-time script reads recent blogPosts/ and aiKnowledgeBase/ documents from Firestore (via the Firebase Admin SDK as a devDep, which is why deploys carry a service-account key file marked private). It writes:

  • public/feed.xml (RSS).
  • public/feed.html (the human-rendered version, prerendered).

The same script writes public/sitemap.xml (URL list with lastmod per page).

This is the same postbuild-seo.mjs pipeline that prerenders 660+ static HTML pages. See the SEO docs (lands in Batch 6) for full mechanics.

Common questions​

Why two URLs (/feed and /feed.xml)?​

Different audiences. Humans want a readable cards page. RSS readers want a strict XML file. Serving both is cheap and avoids forcing humans through a raw XML download.

Can I get a chapter-specific feed?​

Not yet. The roadmap includes per-chapter and per-class feeds (e.g. /feed/c9-physics.xml).

Can I get an Atom feed instead?​

The current feed is RSS 2.0 only. Atom can be added if there is genuine demand.

Is the feed translated?​

The feed is one combined feed, not language-split. Items use their original language. A future ?lang=ur parameter could filter to Urdu items.

How do I follow without RSS?​

Sign in and opt in to push notifications on /app/profile. Push notifications fire for new blog posts (opt-in, not on by default). See Notifications.
