Current scope

This starter is intentionally simple:

• Manifest V3 extension
• No build step
• New tab override
• Extension popup for adding and deleting RSS feed links
• chrome.storage.local for saved RSS feeds
• Client-side RSS XML fetching and rendering
• Responsive dashboard UI

Supported feed formats

Trend Feed currently supports common XML feed shapes that expose entries with item or entry elements:

• RSS 2.0 feeds with title, link, description, and pubDate
• RSS 1.0/RDF feeds with item, link or rdf:about, content:encoded, and dc:date
• Atom feeds with entry, title, link href, summary or content, and published or updated

Live smoke coverage is included for:

• RSS 1.0/RDF: https://equallove-2017.blog.jp/index.rdf
• RSS 2.0: https://hnrss.org/newest
• Atom: https://feeds.feedburner.com/geeknews-feed
• RSS 2.0: https://feeds.content.dowjones.io/public/rss/RSSMarketsMain
• RSS 2.0: https://www.investing.com/rss/news_301.rss

Tests

Run the live feed compatibility smoke test:

node --test test/feed-support.test.mjs

The test requires network access and xmllint.

Release zips

Create a Chrome Web Store-ready zip:

./scripts/package-extension.sh

Create a Microsoft Edge Add-ons-ready zip:

./scripts/package-edge-extension.sh

The packages are written to dist/trend-feed-v<manifest-version>.zip and dist/trend-feed-edge-v<manifest-version>.zip. Each includes only:

• manifest.json
• newtab.html
• popup.html
• icons/
• src/

The Edge package copies manifest.edge.json into the archive as manifest.json, as required by Microsoft Edge Add-ons. Keep the versions in both manifests synchronized.

When changes are pushed or merged to main, GitHub Actions reads the version from manifest.json, creates a matching v<version> tag, creates a GitHub Release, and attaches both zips. If that tag already exists, the workflow fails so the manifest version can be bumped before releasing.
