# btcprice
|
|
|
|
Bitcoin price tracker UI. Serves an HTML page with live price updates streamed from [btcdata](../btcdata) via Server-Sent Events.
|
|
|
|
## Quick Start
|
|
|
|
```bash
|
|
# 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).
