04 - 04 - The Rise of the Tamagotchi

[aksnell]

To start your journey you will be creating an API that allows a user to create and care for a virtual pet, reminiscent of a Tamagotchi. The basic functionality will walk you through the four basic parts of a web API, create, read, update and delete.

Objectives

• Create an API that can implement CRUD features against a Database.
• Practice creating ASP.NET Web API endpoints.
• Practice EF Core.

Explorer Mode

• Create and new sdg-api that has the following features

• Create a database with one table named Pets.

  • Should use a POCO called Pet with the following columns:
  • Id (int)
  • Name (string)
  • Birthday (DateTime)
  • HungerLevel (int)
  • HappinessLevel (int)

Your API should have the following endpoints

• [x] GET /pets, should return all pets in your database.
• [x] GET /pets/{id}, should return the pet with the corresponding id.
• [x] POST /pets, should create a new pet. The body of the request should contain a JSON object with a key of "name" and a value of the pet's name. The pets Birthday should default to the current datetime, HungerLevel defaults to 0 and HappinessLevel defaults to 0.
• [x] POST /pets/{id}/playtimes, should find the pet by id and add 5 to its happiness level and 3 to its hungry level.
• [x] POST /pets/{id}/feedings, should find the pet by id and subtract 5 from its hungry level and 3 from its happiness level.
• [x] POST /pets/{id}/scoldings, should find the pet by id and subtract 5 from its happiness level.
• [x] DELETE /pets/{id}, should delete a pet from the database by Id

Adventure Mode

Add the following features to your API

• Add columns LastInteractedWithDate (DateTime). Every time a pet us updated in the database, set the LastInteractedWithDate to the current time. Add a property named IsDead to your Pets that has logic such that if the LastInteractedWithDate is over 3 days old, the property returns true otherwise false.
• Add a query parameter go GET /pets that only returns Pets that are alive.

Epic mode

Create a console app that interacts with your API that:

• Allows the user to see all pets
• Select a pet to take care of and then play with, scold, or feed the selected pet.
• Create a new pet.
• Delete a pet.

Theoretically adventure mode is done, not happy with forcing synchronous client side evaluation.

Nicely done. Come find me during the week at some point if you want to discuss the synchronous code.
