Overview World Monitor aggregates 150+ RSS feeds across geopolitics, defense, energy, tech, and finance. Each variant loads its own curated feed set:
Geopolitical variant : ~25 categoriesTech variant : ~20 categoriesFinance variant : ~18 categoriesHappy variant : Positive news sources
All RSS feeds are proxied through /api/rss-proxy to prevent CORS issues. The proxy:
Domain allowlist - Only whitelisted domains are permitted (security)Automatic fallback - Direct fetch → Railway relay on failurePer-feed circuit breakers - Failing feeds don’t affect others5-minute polling - Each feed refreshed independently10-minute cooldown - Failed feeds pause before retry
The proxy implements a dual-fetch strategy: attempts direct connection first, then falls back to the Railway relay server if the direct fetch fails.
Allowed Domains The following domains are permitted through api/rss-proxy.js (lines 48-326):

Feed Processing Instant Flat Render News items appear immediately as a flat list the moment feed data arrives. ML-based clustering (topic grouping, entity extraction, sentiment analysis) runs asynchronously in the background and progressively upgrades the view.
News panels with 15+ items use a custom virtual list renderer:
Only visible items + 3-item overscan buffer are rendered
requestAnimationFrame-batched scroll handlingDOM element pooling and recycling
Responsive adaptation via ResizeObserver
Custom Keyword Monitors User-defined keyword alerts with:
Word-boundary matching (prevents “ai” from matching “train”)
Automatic color-coding from 10-color palette
Multi-keyword support (comma-separated)
Real-time match counts
Search across titles and descriptions
Blocked Domains The following domains are explicitly blocked (deprecated sources):
rsshub.app - Returns 410 Gone (stale clients still request these)
Circuit Breaker Behavior When an RSS feed fails:
Direct fetch attempted - Standard HTTP requestRailway relay fallback - If direct fails, routes through relay5-minute cooldown - Failed feed pauses before retryOther feeds unaffected - Per-feed isolationAutomatic recovery - Resumes after cooldown expires
Feed Deduplication Headlines are deduplicated before LLM summarization:
Jaccard similarity threshold of 0.6 (60% word overlap)Reduces prompt size by 20-40%Prevents LLM waste on repeated stories
