This guide covers everything you need to set up WorldMonitor locally, from prerequisites and installation to understanding the project structure and API dependencies.

## Tech Stack

| Layer | Technology | Purpose |
|-------|------------|---------|
| **Language** | TypeScript 5.x | Type safety across 60+ source files |
| **Build** | Vite | Fast HMR, optimized production builds |
| **Map (Desktop)** | deck.gl + MapLibre GL | WebGL-accelerated rendering for large datasets |
| **Map (Mobile)** | D3.js + TopoJSON | SVG fallback for battery efficiency |
| **Concurrency** | Web Workers | Off-main-thread clustering and correlation |
| **AI/ML** | ONNX Runtime Web | Browser-based inference for offline summarization |
| **Networking** | WebSocket + REST | Real-time AIS stream, HTTP for other APIs |
| **Storage** | IndexedDB | Snapshots, baselines (megabytes of state) |
| **Preferences** | LocalStorage | User settings, monitors, panel order |
| **Deployment** | Vercel Edge | Serverless proxies with global distribution |

### Map Rendering Architecture

The map uses a hybrid rendering strategy optimized for each platform:

**Desktop (deck.gl + MapLibre GL)**:

- WebGL-accelerated layers handle thousands of markers smoothly
- MapLibre GL provides base map tiles (OpenStreetMap)
- GeoJSON, Scatterplot, Path, and Icon layers for different data types
- GPU-based clustering and picking for responsive interaction

**Mobile (D3.js + TopoJSON)**:

- SVG rendering for battery efficiency
- Reduced marker count and simplified layers
- Touch-optimized interaction with larger hit targets
- Automatic fallback when WebGL unavailable

### Key Libraries

- **deck.gl**: High-performance WebGL visualization layers
- **MapLibre GL**: Open-source map rendering engine
- **D3.js**: SVG map rendering, zoom behavior (mobile fallback)
- **TopoJSON**: Efficient geographic data encoding
- **ONNX Runtime**: Browser-based ML inference
- **Custom HTML escaping**: XSS prevention (DOMPurify pattern)

### No External UI Frameworks

The entire UI is hand-crafted DOM manipulation, no React, Vue, or Angular. This keeps the bundle small (~250KB gzipped) and provides fine-grained control over rendering performance.

### Build-Time Configuration

Vite injects configuration values at build time, enabling features like automatic version syncing:

| Variable | Source | Purpose |
|----------|--------|---------|
| `__APP_VERSION__` | `package.json` version field | Header displays current version |

This ensures the displayed version always matches the published package, no manual synchronization required.

```typescript
// vite.config.ts
define: {
  __APP_VERSION__: JSON.stringify(pkg.version),
}

// App.ts
const header = `World Monitor v${__APP_VERSION__}`;
```

## Installation

**Requirements:** Go 1.21+ and Node.js 18+.

```bash
# Clone the repository
git clone https://github.com/koala73/worldmonitor.git
cd worldmonitor

# Install everything (buf, sebuf plugins, npm deps, proto deps)
make install

# Start development server
npm run dev

# Build for production
npm run build
```

If you modify any `.proto` files, regenerate before building or pushing:

```bash
make generate   # regenerate TypeScript clients, servers, and OpenAPI docs
```

See [Adding Endpoints](/adding-endpoints) for the full proto workflow.

## API Dependencies

The dashboard fetches data from various public APIs and data sources:

| Service | Data | Auth Required |
|---------|------|---------------|
| RSS2JSON | News feed parsing | No |
| Finnhub | Stock quotes (primary) | Yes (free) |
| Yahoo Finance | Stock indices & commodities (backup) | No |
| CoinGecko | Cryptocurrency prices | No |
| USGS | Earthquake data | No |
| NASA EONET | Natural events (storms, fires, volcanoes, floods) | No |
| NWS | Weather alerts | No |
| FRED | Economic indicators (Fed data) | No |
| EIA | Oil analytics (prices, production, inventory) | Yes (free) |
| USASpending.gov | Federal government contracts & awards | No |
| Polymarket | Prediction markets | No |
| ACLED | Armed conflict & protest data | Yes (free) |
| GDELT Geo | News-derived event geolocation + tensions | No |
| GDELT Doc | Topic-based intelligence feeds (cyber, military, nuclear) | No |
| FAA NASSTATUS | Airport delay status | No |
| Cloudflare Radar | Internet outage data | Yes (free) |
| AISStream | Live vessel positions | Yes (relay) |
| OpenSky Network | Military aircraft tracking | Yes (free) |
| Wingbits | Aircraft enrichment (owner, operator) | Yes (free) |
| PizzINT | Pentagon-area activity metrics | No |

### Optional API Keys

Some features require API credentials. Without them, the corresponding layer is hidden:

| Variable | Service | How to Get |
|----------|---------|------------|
| `FINNHUB_API_KEY` | Stock quotes (primary) | Free registration at [finnhub.io](https://finnhub.io/) |
| `EIA_API_KEY` | Oil analytics | Free registration at [eia.gov/opendata](https://www.eia.gov/opendata/) |
| `VITE_WS_RELAY_URL` | AIS vessel tracking | Deploy AIS relay or use hosted service |
| `VITE_OPENSKY_RELAY_URL` | Military aircraft | Deploy relay with OpenSky credentials |
| `OPENSKY_CLIENT_ID` | OpenSky auth (relay) | Free registration at [opensky-network.org](https://opensky-network.org) |
| `OPENSKY_CLIENT_SECRET` | OpenSky auth (relay) | API key from OpenSky account settings |
| `CLOUDFLARE_API_TOKEN` | Internet outages | Free Cloudflare account with Radar access |
| `ACLED_ACCESS_TOKEN` | Protest data (server-side) | Free registration at acleddata.com |
| `WINGBITS_API_KEY` | Aircraft enrichment | Contact [Wingbits](https://wingbits.com) for API access |

The dashboard functions fully without these keys. Affected layers simply don't appear. Core functionality (news, markets, earthquakes, weather) requires no configuration.

## Acknowledgments

Original dashboard concept inspired by Reggie James ([@HipCityReg](https://x.com/HipCityReg/status/2009003048044220622)), with thanks for the vision of a comprehensive situation awareness tool.

Special thanks to **Yanal at [Wingbits](https://wingbits.com)** for providing API access for aircraft enrichment data, enabling military aircraft classification and ownership tracking.

Thanks to **[@fai9al](https://github.com/fai9al)** for the inspiration and original PR that led to the Tech Monitor variant.

## Limitations & Caveats

This project is a **proof of concept** demonstrating what's possible with publicly available data. While functional, there are important limitations:

### Data Completeness

Some data sources require paid accounts for full access:

- **ACLED**: Free tier has API restrictions; Research tier required for programmatic access
- **OpenSky Network**: Rate-limited; commercial tiers offer higher quotas
- **Satellite AIS**: Global coverage requires commercial providers (Spire, Kpler, etc.)

The dashboard works with free tiers but may have gaps in coverage or update frequency.

### AIS Coverage Bias

The Ships layer uses terrestrial AIS receivers via [AISStream.io](https://aisstream.io). This creates a **geographic bias**:

- **Strong coverage**: European waters, Atlantic, major ports
- **Weak coverage**: Middle East, open ocean, remote regions

Terrestrial receivers only detect vessels within ~50km of shore. Satellite AIS (commercial) provides true global coverage but is not included in this free implementation.

### Blocked Data Sources

Some publishers block requests from cloud providers (Vercel, Railway, AWS):

- RSS feeds from certain outlets may fail with 403 errors
- This is a common anti-bot measure, not a bug in the dashboard
- Affected feeds are automatically disabled via circuit breakers

The system degrades gracefully. Blocked sources are skipped while others continue functioning.
