btcprice
Bitcoin price tracker UI. Serves an HTML page with live price updates streamed from btcdata via Server-Sent Events.
Quick Start
# Start btcdata first (provides price data)
cd ../btcdata && make run
# Local dev
make run # starts on port 4000
make tailwind # watch Tailwind CSS (separate terminal)
# Docker (starts both btcprice + btcdata)
docker compose up -d # btcprice on 4041, btcdata on 4101
Environment Variables
| Variable | Default | Description |
|---|---|---|
PORT |
4000 |
HTTP server port |
BTCDATA_URL |
http://localhost:4100 |
btcdata service URL (injected into browser JS) |
How It Works
The server renders an HTML page that includes a vanilla JavaScript EventSource connecting directly to btcdata's SSE endpoint (BTCDATA_URL/api/price/stream). Price updates are rendered client-side with color-coded changes (green up, red down).
