$ git clone https://github.com/mpayson/epc2019.git
$ cd intelligence && npm install
$ cd ../cost && npm install
Note, I'm committing built files as well for convenience, so you could skip to running
$ cd intelligence && npm run build
$ cd ../cost && npm run build
Use your favorite static server! I use serve
$ cd intelligence && serve -s build
$ cd ../cost && serve -s dist
