Kursovik
While I was on vacation, I decided to try some new technology. I started with Electron.
Electron is a library that helps you write web-based desktop applications. You write a web application, wrap it in an “electron shell”, build it, and it works like a regular desktop application.
A todo list seemed too primitive for me, so I decided to create Kursovik. It is an app that shows USD/RUB currency course. I made it open source so you can try it too
Kursovik shows the course for today and the difference with the yesterday course. If it knows the course for the next day shows it too. Draws a chart of how the course has changed by the week, month, or a quarter.
If there's no Internet connection, it shows the latest fetched data and a warning about the offline mode. Whe the Internet is accessible again the data will be automatically updated.
This is a prototype. I'll be glad if you help me to find bugs ad improve the app. Send issues and ideas to GitHub or to bespoyasov@me.com.
As a result of developing this, I learned how to work with Electron's API and how to transfer data between different processes in the app. Learned how to work with tray on MacOS and found out a bit about the Windows architecture. Also, learned how unstable the site of the Central Bunk of Russia and its API are.
