CovidPulse Data

Fetch Covid-19 Data for the US from JHU Covid-19 County Cases and transform them into the JSON files with paths that can be rendered as sparklines by the CovidPulse app.

Instructions

• Before we begin, make sure you have a fresh version of Node.js and NPM installed. The current Long Term Support (LTS) release is an ideal starting point.

• To begin, clone this repository to your computer:

  https://github.com/vannizhang/covid19-trend-map-data.git

• From the project's root directory, install the required packages (dependencies):

  npm install

• Now you can run the command to download and convert the JHU covid-19 data into .JSON files the CovidPulse App can use:

  npm run download-covid19-data
  
  # use the development mode (shows more detailed messages to help debugging) on local testing environment 
  npm run download-covid19-data-dev

• The previous step should generate five .JSON files into the ./public directory:

  • the us-counties-paths.json and us-states-paths.json are data that will be used to plot the sparklines in the CovidPulse app.

  • latest-numbers.json is a lookup table (FIPS code as key) the CovidPulse app uses to show the Tooltip

  • the us-counties.json and us-states.json contains the raw numbers from JHU services to help debug and QA and are not being used by the CovidPulse app.

• Now you can go to the repository for the CovidPulse app and replace the .JSON files in the static folder using the these ones made by yourself.
