Crypto Ticker Plugin

This is a WebSocket-based WASM plugin for Navidrome that displays real-time cryptocurrency prices from Coinbase.

Features

Connects to Coinbase WebSocket API to receive real-time ticker updates
Configurable to track multiple cryptocurrency pairs
Implements WebSocketCallback and LifecycleManagement interfaces
Automatically reconnects on connection loss
Displays price, best bid, best ask, and 24-hour percentage change

Configuration

In your navidrome.toml file, add:

[PluginConfig.crypto-ticker]
tickers = "BTC,ETH,SOL,MATIC"

tickers is a comma-separated list of cryptocurrency symbols
The plugin will append -USD to any symbol without a trading pair specified

How it Works

The plugin connects to Coinbase's WebSocket API upon initialization
It subscribes to ticker updates for the configured cryptocurrencies
Incoming ticker data is processed and logged
On connection loss, it automatically attempts to reconnect (TODO)

Building

To build the plugin to WASM:

GOOS=wasip1 GOARCH=wasm go build -buildmode=c-shared -o plugin.wasm plugin.go

Installation

Copy the resulting plugin.wasm and create a manifest.json file in your Navidrome plugins folder under a crypto-ticker directory.
