Development of News and RSS Feed Parser
RSS and Atom are standardized content syndication formats: almost every news resource publishes a feed. Parser task—aggregate materials from multiple sources, normalize structure, clean content, save to database for further processing or display.
How It Works
Parser polls list of RSS/Atom feeds on schedule. For each new item:
- Extract title, description, full text (if available), date, tags, author
- Clean HTML from ads and garbage via
sanitize-htmlorbleach - Save to database with deduplication by GUID or URL
If source has no RSS—connect HTML parser based on Cheerio or BeautifulSoup with manual CSS selector markup for specific site.
Stack
-
Node.js +
rss-parseror Python +feedparser—feed processing - Cron / Celery Beat—traversal schedule
-
PostgreSQL—article storage with full-text index
tsvector - Redis—cache of already processed GUIDs
Implementation time for basic version with 10–20 sources: 3–4 working days.
