cart-service

Given: Product model

class Product
{
    public int Id { get; set; }
    public string Name { get; set; }
    public decimal Cost { get; set; }
    public bool ForBonusPoints { get; set; }
}

Task: Implement CartService

Requirements:

1. Stack: Asp Net Core 3.1 WEB Api + storage of choice Redis / Sql Server + Dapper

2. Functionality:

• Add / remove an arbitrary number of products
• Store basket data for 30 days
• The ability to register web hooks that need to be pulled when the basket is deleted after the expiration of the storage period
• once a day generate and save a report (txt / pdf / excel to choose from), which will indicate:
  • how many baskets
  • how many of them contain products for points
  • how many baskets expire within 10/20/30 days
  • average check basket

Notes:

• no validation
• no tests
• no additional indexes on DB (LatestUpdatedOn for search, ProductId+ShoppingCartId for unique constraint)
