AGL Programming challenge

The solution has a micro service architecture.

It consists of

• An ASPNET Core 3.1 Web API back end micro service
• An Angular 10 CLI app front end UI

ASPNET Core 3.1 Web API - Back end

The API has

• an Entity project

  • This contains the Entities used in the API.

• a Repository project

  • This contains

    • a Pets Repository
      • This uses HttpClient to fetch the pets and their owners. It uses Newtonsoft.Json to deserialize the data.
      • This Repository is injected into the Pets Manager.

• a Business Logic project

  • This contains

    • a Pets Manager
      • This uses LINQ to extract the pets by pet type and owner's gender from the data.
      • This Pets Manager is injected into the Controller.

• an ASPNET Core 3.1 Web API project

  • This contains

    • a Pets Controller

      • This contains a GET API called petsbypersongender.

        API	Verb	Route	Sample Url
        petsbypersongender	GET	/api/Pets/petsbypersongender	http://localhost:44373/api/Pets/petsbypersongender/2

      • The API calls into the injected Pets Manager.

• an Unit Test project

  • This contains unit tests for the Business Logic. NSubstitute is used to mock the Repository layer.

The Web API response JSON is like:

{
  "petType": "Cat",
  "petsByPersonGender": [
    {
      "gender": "Male",
      "pets": [
        {
          "name": "Garfield"
        },
        {
          "name": "Jim"
        },
        {
          "name": "Max"
        },
        {
          "name": "Tom"
        }
      ]
    },
    {
      "gender": "Female",
      "pets": [
        {
          "name": "Garfield"
        },
        {
          "name": "Simba"
        },
        {
          "name": "Tabby"
        }
      ]
    }
  ]
}

Angular 10 CLI app - UI front end

The app has

• Models mirroring the API response.

• a Service called Pets Service (in TypeScript) which

  • calls the API using HttpClient.
  • is injected into the Component.

• a Component called agl-pets which

  • calls the API using the injected Pets Service.
  • displays the cats by owner's gender.
