CoinWatcher

CoinWatcher

A simple GUI to track cryptocurrency prices.

How to run it

$ go install github.com/itohi/CoinWatcher/cmd/watcher@latest

All the requirements for building Fyne apps apply.

Configuration

You will need Coinmarketcap API key for this to work. They offer a free tier with 10000 API credits per month, so it should be plenty enough for casual use.

You can setup the API key using COINWATCHER_KEY environment variable at first start. Otherwise it is possible to configure the api key using settings button.

Features

• Save/Load coin list
• Fetch prices from Coinmarketgo
• Cache coin images
• Convert currency (requires either payed plan or fetching fiat currencies and converting that way)
• Disable certain controls when Coinmarketcap is not available(incorrect API key)
• Display better errors when failed to fetch data from Coinmarketcap
• Recreate crypto feed variable after API key change
• Handle symbols with non alpha-numeric characters correctly
• Fetch and display coin hisstoric data
• Autoupdate coin prices
• Add other sources
• Better coin entry (e.g. use autocomplete)
• Better coin matching logic (currently matches by symbol)
• Setup actions for when a price reaches certain threshold
• pluggable pattern matchers
• pluggable actions
