node v10.15.3
npm v6.4.1
The solution is made of an Express app where relies the invaders detection logic (concerned classes are in 'app/core' folder) and a React client to see it in action.
After dependencies are installed, 'buid' command will build both client and server side of the application and subsequently start server.
npm install
npm run build
Connect to :
http://localhost:8080
Run unit tests for server app :
npm run app:test
Run React client tests :
npm run client:test
