UBahn App

Install software

node 12.x
npm 6.x
docker

Deployment

There are two apps involved - a front end build using create react app and a backend which is a nodejs api

When working locally, you will run the following commands (after setting the necessary environment variables):

npm install
cd client && npm install
cd .. && npm run dev

The front end proxies request (some of them) to localhost:3001, which is the backend api code base. This configuration is located in client/package.json file itself

Note that the environment variables for the React App start with REACT_APP_

Local database deployment
