web-dev-rss

An unofficial RSS feed for the web.dev blog.

Because the official feed https://web.dev/static/blog/feed.xml stopped updating on May 29, 2026, this tool crawls the article list daily to rebuild the feed.

How It Works

1. src/list-posts.mjs — Uses Puppeteer to open https://web.dev/blog?hl=en and gathers article URLs in the order they appear in the list.
2. src/fetch-meta.mjs — Fetches only unretrieved articles to extract og:title, og:description, og:image, and Published: ....
3. src/feed.mjs — Merges with the existing feed to generate RSS 2.0.
4. .github/workflows/update-feed.yml — Runs daily at 07:00 JST and commits docs/feed.xml if there are any changes.

Why a Browser Is Needed

Article cards on the list page are rendered via JS using <devsite-dynamic-content query="docType:Blog" template="card">. In the raw HTML obtainable via curl, the content inside this tag is empty, and not a single article link is included. Therefore, JavaScript execution is required just to retrieve the list.

On the other hand, individual article pages are pre-rendered with SSR, so a browser is not needed to fetch meta information (plain fetch is sufficient).

Ordering

Since Published: August 10, 2026 does not include a time and articles published on the same day can occur, ordering is finalized by using the display order in the list (recency order) as a secondary key in addition to descending pubDate. We verify that the first item is the newest before writing out the feed.

Running Locally

npm ci
node src/index.mjs

This updates docs/feed.xml. If retrieving the list fails, it exits with an error and leaves the existing feed untouched.

Maintenance

If the DOM on the web.dev side changes and the selectors stop working, the workflow is designed to fail so you notice (rather than quietly outputting an empty feed). In that case, review CARD_LINK in src/list-posts.mjs.
