Hello!
The solution is divided into two parts - the backend and the frontend both in their dedicated folders that should be treated as separate projects
The backend is a simple rest API served using restify.js The app is held together using a dependency injection container Inversify.js, It is not ideal but the best open source solution I could find so far.
just change to the backend directory and use npm scripts to run the service
npm run server to run well, the server
npm run test to run all unit tests
I have chosen Angular for this solution as it is way closer to how I approach problems and how I design software in general as I am big fan of dependency injection and SOLID principles
You will need the Angular CLI to run the solution
Then simply run:
ng serve --open to see the app in action
ng test to run tests
Obviously you will need the backend service to be running as well.
