microToDeg guessed microdegrees from integer values, but api/nodes.go has always sent *float64 degrees — so a node sitting at an exact whole degree got divided by 1e6 and rendered at the equator. Drop the shim from the geojson builder, the nodes table and the detail panel, and fix the ws.ts comment that repeated the wrong premise. Also key neighbor rows by id+iata: the neighbors endpoint returns one row per (neighbor, iata), so id alone collides for nodes heard in several regions (live React duplicate-key error).
BEACON Web
Real-time LoRa mesh packet analyzer. Desktop-first, dark-mode-primary, dense information display for radio hobbyists.
Built with React 19, TypeScript, Tailwind CSS 4, TanStack Query, and TanStack Virtual.
Deployment
1. Copy the docker/ folder to your server
scp -r docker/ user@your-server:/opt/docker/beacon-web
2. Create a .env file
cd /opt/docker/beacon-web
cat > .env << 'EOF'
DOMAIN=dev.meshcore.ca
VITE_API_BASE=https://dev.meshcore.ca/api/v1
VITE_WS_URL=wss://dev.meshcore.ca/ws
EOF
| Variable | Description |
|---|---|
DOMAIN |
Domain for HTTPS (Caddy auto-provisions Let's Encrypt certs) |
VITE_API_BASE |
Backend REST API base URL |
VITE_WS_URL |
Backend WebSocket URL |
3. Authenticate with GitHub Container Registry
docker login ghcr.io -u YOUR_GITHUB_USERNAME
Use a Personal Access Token (classic) with read:packages scope as the password. You only need to do this once.
4. Start the services
docker compose up -d
Caddy will automatically obtain a TLS certificate for your domain. Ensure DNS is pointed at your server before starting.
Local Development
npm install
cp .env.example .env # edit with your backend URLs
npm run dev # starts Vite dev server at http://localhost:5173

Architecture
- Region-driven: All data queries and WS subscriptions are scoped to an IATA region code. Changing region resets the cache and resubscribes.
- Live + historical merge: WebSocket pushes live packets into a
LivePacketStorebuffer (capped at 500). Historical data comes from cursor-paginated REST viauseInfiniteQuery(max 20 pages). Both are merged and deduped at render time. - Client-side filtering: Filters are not part of the query key. The cache holds all packets for the current region; filters are applied via
useMemo. Toggling a filter is instant with no refetch. - Reconnect with jitter: Exponential backoff with +/-25% random jitter prevents thundering herd on server bounce.
