Requirements:

• Node.js 12
• Yarn

(See .tool-versions for specific and up-to-date versions).

1. Install local depenendences

   $ yarn install

2. Start local server

   $ yarn start

3. Open http://localhost:3000

1. Install venv to be able to run prevalence updates

   $ python3 -m venv .venv
   $ source .venv/bin/activate
   $ pip install -r requirements-manual.txt

2. Install the GitHub CLI to be able to using the gh command with the prevalence_helper.sh script

   # using homebrew (see GitHub page for alternate install methods)
   $ brew install gh

3. Get a COVIDActNow.org API key from here. (If you're on the microCOVID team, you can ask for our existing API key.)
4. Then configure your API key as such:

   $ cp .secure-keys.template .secure-keys
   # Add your API key to the line in .secure-keys that is listed as CAN_API_KEY

5. Run a prevalence update. Pick one of the three following examples:

   # Run the prevalence update on the auto-prevalence-update branch
   $ yarn prevalence
   # Run the prevalence update, commit changes, and submit auto-merge pull request
   $ yarn prevalence -c
   # Run the prevalence update without switching branches (useful when testing changes on a feature branch)
   $ yarn prevalence -b
   # Specify the COVIDActNow.org API key
   $ yarn prevalence -k 111aaa222bbb
   # Specify where your virtualenv lives (defaults to `.venv`)
   $ yarn prevalence -v .venv-custom

We use eslint to standardize our style across files. To check your files with the linter, run:

$ yarn lint

If you see warnings, you can attempt to auto-correct them with:

$ yarn fix

If there are errors it can't fix, please fix them manually before committing.
