COVID 19 TRACKER

https://covid-19-tracker-1a918.web.app/

Getting started

• clone this repository
• run the command to create and start containers and start react server

docker-compose up

What the app looks like

This app is created with

• react (create-react-app)
• css (not scss. usually use scss at work)
• material-ui (so I can focus on creating app. Desiging is not the first priority)
• some APIs (Map and chart)

APIs

• react-chartjs-2 and chart.js for the Line graph
• react-leaflet and leaflet for the Map
• disease.sh
  • to fetch covid related data.
  • number of recovery for a certain period is broken due to a lack of data provided by the API.

Things I actively tried

• to avoid using magic number and hard coding by assigning them into constant variables
  • so that I don't mistakenly use wrong urls to fetch data
  • and also they are easy to reuse again
• to write readable codes by leaving comments
  • for easier and better understanding
• to use docker
  • it's my first time using docker
  • to keep my local machine clean by avoiding to have a lot of things installed for development.
  • turns out I knew it's great and now I have better understanding about docker (and k8s) used at my workplace.

Things I actively avoid

• organizing files like src directory.
  • createing a runnable application was the first priority.
  • no plan to maintain this application in the future.

deployment(TBD)

• Used Firebase to host this app
