So, I built an app for the COVID-19 'pandemic' - it's hosted at covid19.budapestpulse.com by Glitch - check it out!
- It's a Node.js/Express app
- It fetches data the koronavirus.gov.hu site, and parses it to read out key data points
- It saves that to an NEDB database with a time stamp
- If there's a database entry within the past 30 mins, then the app will read that, rather than refetching the data
