+# RouteWatch
+
+RouteWatch is a real-time BGP routing table monitor that streams BGP UPDATE messages from the RIPE RIS Live service, maintains a live routing table in SQLite, and provides HTTP APIs for querying routing information.
+
+## Features
+
+- Real-time streaming of BGP updates from RIPE RIS Live
+- Maintains live IPv4 and IPv6 routing tables
+- Tracks AS peering relationships
+- HTTP API for IP-to-AS lookups, prefix details, and AS information
+- Automatic reconnection with exponential backoff
+- Batched database writes for high performance
+- Backpressure handling to prevent memory exhaustion
+
+## Installation
+
+```bash
+go build -o routewatch ./cmd/routewatch
+```
+
+## Usage
+
+```bash
+# Run the daemon (listens on port 8080 by default)
+./routewatch
+
+# Set custom port
+PORT=3000 ./routewatch
+
+# Enable debug logging
+DEBUG=routewatch ./routewatch
+```
+
+## HTTP Endpoints
+
+### Web Interface
+- `GET /` - Redirects to /status
+- `GET /status` - HTML status dashboard
+- `GET /status.json` - JSON statistics
+- `GET /as/{asn}` - AS detail page (HTML)
+- `GET /prefix/{prefix}` - Prefix detail page (HTML)
+- `GET /prefixlength/{length}` - IPv4 prefixes by mask length
+- `GET /prefixlength6/{length}` - IPv6 prefixes by mask length
+- `GET /ip/{ip}` - Redirects to prefix containing the IP
+
+### API v1
+- `GET /api/v1/stats` - Detailed statistics with handler metrics
+- `GET /api/v1/ip/{ip}` - Look up AS information for an IP address
+- `GET /api/v1/as/{asn}` - Get prefixes announced by an AS
+- `GET /api/v1/prefix/{prefix}` - Get routes for a specific prefix

+
+### Execution Flow
+
+1. **Startup** (`cmd/routewatch/main.go` → `internal/routewatch/cli.go`)
+   - Uber fx dependency injection initializes all components
+   - Signal handlers registered for graceful shutdown
+
+2. **Initialization** (`internal/routewatch/app.go`)
+   - Database created with SQLite schema (WAL mode, 3GB cache)
+   - Message handlers registered with the streamer
+   - HTTP server started on configured port
+
+3. **Message Processing Pipeline**
+   ```
+   RIS Live Stream → JSON Parser → Message Dispatcher → Handler Queues → Batch Writers → SQLite
+   ```
+   - Streamer connects to `ris-live.ripe.net` via HTTP
+   - Parses BGP UPDATE messages from JSON stream
+   - Dispatches to registered handlers based on message type
+   - Each handler has its own queue with backpressure handling
+   - Handlers batch writes for efficiency (25K-30K ops, 1-2s timeout)
+
+4. **Handler Details**
+   - **ASHandler**: Tracks all ASNs seen in AS paths
+   - **PeerHandler**: Records BGP peer information
+   - **PrefixHandler**: Maintains live routing table (upserts on announcement, deletes on withdrawal)
+   - **PeeringHandler**: Extracts AS peering relationships from AS paths
+
+5. **HTTP Request Flow**
+   ```
+   Request → Chi Router → Middleware (timeout, logging) → Handler → Database Query → Response
+   ```
+
+### Key Design Patterns
+
+- **Batched Writes**: All database operations are batched for performance
+- **Backpressure**: Probabilistic message dropping when queues exceed 50% capacity
+- **Graceful Shutdown**: 60-second timeout, flushes all pending batches
+- **Reconnection**: Exponential backoff (5s-320s) with reset after 30s of stable connection
+- **IPv4 Optimization**: IP ranges stored as uint32 for O(1) lookups
+
+### Database Schema
+
+```sql
+-- Core tables
+asns(id, number, handle, description, first_seen, last_seen)
+prefixes_v4(id, prefix, mask_length, first_seen, last_seen)
+prefixes_v6(id, prefix, mask_length, first_seen, last_seen)
+
+-- Live routing tables (one per IP version)
+live_routes_v4(id, prefix, mask_length, origin_asn, peer_ip, as_path,
+               next_hop, last_updated, v4_ip_start, v4_ip_end)
+live_routes_v6(id, prefix, mask_length, origin_asn, peer_ip, as_path,
+               next_hop, last_updated)
+
+-- Relationship tracking
+peerings(id, as_a, as_b, first_seen, last_seen)
+bgp_peers(id, peer_ip, peer_asn, last_message_type, last_seen)
+```
+
+## Configuration
+
+Configuration is handled via environment variables and OS-specific paths:
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `PORT` | `8080` | HTTP server port |
+| `DEBUG` | (empty) | Set to `routewatch` for debug logging |
+
+State directory (database location):
+- macOS: `~/Library/Application Support/routewatch/`
+- Linux: `/var/lib/routewatch/` or `~/.local/share/routewatch/`
+
+## Development
+
+```bash
+# Run tests
+make test
+
+# Format code
+make fmt
+
+# Run linter
+make lint
+
+# Build
