[STEP1]

Requirements:

• An IDE like Visual Studio 2022
• .NET 6 sdk
• personal "WeatherApi.com" Api key

How to run the project:

• Open "WeatherChallengeCli.sln" file using Visual Studio 2022
• Inside "Config.json" file of the two projects, set your own "weatherapi.com" api key
• Build the solution (it will restore NuGet packages)
• Click on visual studio's start button

[STEP2]

1. Api to set the weather forecast for a specific city and dates. The data are saved into Musement Db.
   The request payload and the response are in JSON format.

POST /api/v3/cities/{id}/weatherforecast

Request Payload:

{
	"forecasts": [
		{
			"date": "2022-09-17",
			"forecast": "Rainy"
		},
		{
			"date": "2022-09-18",
			"forecast": "Sunny"
		}
	]
}

Response types:

CASE SUCCESS:

{
	"success": true,
	"error_message": ""
}

CASE FAIL:

{
	"success": false,
	"error_message": "this is the description of the error"
}

Behaviour:

• City "id" is validated
• Validate the correct format the dates
• Save into db the forecasts
• If everything is ok (no exceptions), answer as Success payload, otherwise Fail payload.

2. Api to get the weather forecast for a specific city within a range of dates.
   The request payload and the response are in JSON format.
   N.B.: the data are retrieved from Musement db, not from weatherapi.com api.

GET /api/v3/cities/{id}/weatherforecast

Request Payload:

{
	"from_date": "2022-09-17",
	"to_date": "2022-09-19"
}

Response types:

CASE SUCCESS:

{
	"success": true,
	"error_message": "",
	"data": {
		"city_id": "14",
		"city_name": "Milan",
		"forecasts": [
			{
				"date": "2022-09-17",
				"forecast": "Rainy"
			},
			{
				"date": "2022-09-18",
				"forecast": "Sunny"
			},
			{
				"date": "2022-09-19",
				"forecast": null
			}
		]
	}
}

CASE FAIL:

{
	"success": false,
	"error_message": "this is the description of the error",
	"data": null
}

Behaviour:

• City "id" is validated
• Validate the date range (for instance: the "to_date" must be equal or greater that "from_date", date are in valid format)
• Query the Db to get the forecast for the specified dates.
• If forecast for a specific date was not been saved into db, the "forecast" value will be null.
• If everything is ok (no exceptions), answer as Success payload, otherwise Fail payload.

[OPTIONAL: docker development environment]

Requirements:

• Docker installed on your local machine
• Visual Studio Code

How to open and run the project in a container:

• Open Docker app on your local machine
• Open the project root folder using VS Code
• At this point VS Code should open a pop-up that asks you to "Reopen in Container". Click that button and VS Code will create the dev env for you.
• Set your own "weatherapi.com" api key in the two "Config.json" files
• Open a terminal in VS Code and run the following commands:

  cd WeatherChallengeCli
  dotnet restore
  dotnet run
