cvd-console-app
Technology stack
The app uses Java 8, Spring Boot (dependency injection, RestTemplate), lombok, gradle, JUnit 5, jacoco code coverage
Design choices
- All the data is loaded and cached at the application startup
- If the data fails to load, the app won't start. See troubleshooting section below
- The app allows entering many country names one by one, until the user types "exit"
- The country name must be entered exactly as it is in the dataset, there is no help or autocompletion
- The app only shows info for the countries that have valid data in all 3 datasets (cases, vaccines, cases history)
- "Vaccinated level in % of total population" represents the percentage of fully vaccinated
- "New confirmed cases since last data available" are calculated based on history data as
number of cases on the latest day - number of cases on the latest but one day - Numbers in the output are formatted as ###,###.##
