Platform COE Hiring Challenge

It contains these folders and files, following the recommended CAP project layout:

File or Folder	Purpose
`app/`	content for UI frontends
`db/`	domain models and data
`srv/`	service models and code
`package.json`	project metadata and configuration
`readme.md`	this document

Next Steps

Clone the repo and run npm i to install the dependencies
Open a new terminal and run npm run start to launch the backend server
Open a new terminal and run npm run watch-population-densities to launch the server and the frontend
The app uses CDS mock authentication with the following user profiles:
- name: "user", password: "1234" - grants READ permissions for all records
- name: "admin", password: "1234" - grants READ, WRITE permissions for all records
The API is hosted at http://localhost:4004/odata/v4/api/
- Return all cities: http://localhost:4004/odata/v4/api/Cities
- Sort by name / population / area in descending or ascending manner: http://localhost:4004/odata/v4/api/Cities?$orderby=<property> <order: asc/desc> where property can be "name", "population" or "area" and order can be "asc" for ascending and "desc" for descending order respectively
- Filter the cities by name using a “contains” filter: http://localhost:4004/odata/v4/api/Cities?$filter=contains(name,'New')
- An endpoint to add new cities with name, population and area during runtime: http://localhost:4004/odata/v4/api/addCity with the parameters set in POST request data object like
```
{
    "city":{
        "name": "new city",
        "population": 1000000,
        "area": 2
    }
}
```
The UI loads the full dataset from the service and shows it in a table with all 4 columns. It also includes a calculated density column and highlights rows with population over 1 million
The tests in /tests/test.js perform unit tests for all the specified functionality. You can run these tests by running npm run test
