Lionshare, an open source cryptocurrency price and portfolio monitor for the macOS taskbar has launched today to the public. Users will have instant access to accurate price information of 20 different cryptocurrencies.
A big part of Lionshare is a monitoring portfolio. Instead of holding all your private keys, you can manually input amounts of different crypto assets you hold, or wish you would hold, and follow the progress of the portfolio over time. All prices are pulled from two popular crypto-exchanges, GDAX and Poloniex. All the prices are updated in real-time.
Lionshare also announced the release of all the source code on Github for anyone who wants to learn how to build real-time API powered desktop applications. The desktop application is built in using React, Mobx for state management, CSS Modules for styles and packaged for macOS with Electron.
There’s no single API that provides all the data and real-time feeds that Lionshare needs, so the company decided to build their own. The API is built using Node and Koa, and it provides historical price information together with real-time WebSocket feeds for current prices for up to 20 currencies and more will be added in the future.
Lionshare stated that they hope to release more currencies and updates over time and to hopefully make their way to other platforms in the future.
