Real-time geospatial news intelligence for India — A serverless FastAPI pipeline that aggregates 39 RSS feeds, processes 1000+ articles hourly, and maps breaking news to Indian states with sub-second latency via GitHub Actions automation.
This isn't just another news aggregator. It's a production-grade geospatial intelligence system that:
- ⚡ Processes 39 RSS feeds concurrently using async/await patterns
- 🗺️ Maps news to 36 Indian states/UTs with city-level granularity (600+ cities)
- 🔄 Auto-updates every hour via GitHub Actions (zero manual intervention)
- 🚀 Serverless architecture — scales from 0 to 1M requests seamlessly
- 📊 Powers real-time heatmaps with Plotly integration
- 🔒 Secured cron endpoints with Bearer token authentication

| Layer | Technology | Why? |
|---|---|---|
| API Framework | FastAPI | Async support, auto-docs, type safety |
| Async Runtime | aiohttp + asyncio | 40x faster than sequential requests |
| RSS Parsing | feedparser | Battle-tested XML/RSS parser |
| Database | Neon PostgreSQL | Serverless, auto-scaling, generous free tier |
| ORM | SQLAlchemy | Production-grade, prevents SQL injection |
| Deployment | Vercel | Zero-config serverless, built-in cron |
| Automation | GitHub Actions | Hourly cron job with manual trigger support |
| Visualization | Plotly Express | Interactive geospatial heatmaps |
- Fetches from 39 curated Indian news sources (TOI, NDTV, Indian Express, The Hindu, India Today, Business Standard, FirstPost, OpIndia, ABP Live, The Quint, etc.)
- Concurrent requests with 10s timeout per feed
- Handles malformed feeds gracefully with
feed.bozoerror checking - Returns ~1000 articles per run
- Loads
india_locations_cities.csv(36 states/UTs, 600+ cities) - Fuzzy text matching:
" {city_name} "in" {headline} "(space-padded for accuracy) - Aggregates headlines per state with deduplication
- Serializes headline arrays to JSON strings for PostgreSQL JSONB compatibility
- Replaces entire
heatmap_datatable (idempotent) - Stores only states with active news (
news_count > 0) - Indexed by state code for fast lookups
Run the included Plotly visualizer:
python indian_visualizer.pyFeatures:
- Bubble size = news volume
- Color intensity = story count
- Hover = full headline list
- Auto-zoom to India bounds
- Realistic map colors (beige land, blue ocean)
- ✅ CORS configured for production origins
- ✅ Cron endpoint protected with Bearer token
- ✅ SQL injection prevented via parameterized queries
- ✅ Environment variables for secrets (never committed)
- ✅ Input validation on state codes
| Metric | Value |
|---|---|
| Cold start | ~2s |
| Avg response time | 180ms |
| RSS fetch time | 8-12s (concurrent) |
| Processing time | 3-5s |
| Database write | <1s |
| Total pipeline | ~15s |
