make sure you have react installed
npm install -g create-react-app
then run
npm install
to install node modules
npm start
This will run React on local. However, it will not have any data.
Clone the api repo into the same folder as the react repo (There should be a folder with two repor in it, the react and the api). Be sure to not clone this in to the react folder.
run npm install to install json-server
npm start
Should now be able to run the app with some data
