NetEnvExtensions — это расширение для .NET, позволяющее автоматически подставлять значения переменных окружения в конфигурацию приложения (например, из appsettings.json или других источников), используя синтаксис ${VAR_NAME} или ${VAR_NAME:default}.

Возможности

  • Поддержка подстановки переменных окружения в любые значения конфигурации.
  • Возможность указывать значения по умолчанию: ${VAR_NAME:default}.
  • Простая интеграция с Microsoft.Extensions.Configuration.

Установка

Добавьте пакет в ваш проект (пример для NuGet):

dotnet add package NetEnvExtensions

Использование

  1. Подключите пространство имён:
using NetEnvExtensions;
  1. Добавьте расширение в ваш IConfigurationBuilder:
var builder = new ConfigurationBuilder()
    .SetBasePath(Directory.GetCurrentDirectory())
    .AddJsonFile("appsettings.json", optional: true, reloadOnChange: true)
    .AddEnvironmentVariableSubstitution();

var configuration = builder.Build();
  1. Используйте переменные окружения в вашем appsettings.json:
{
  "ConnectionStrings": {
    "DefaultConnection": "Server=${DB_HOST:localhost};Port=${DB_PORT:5432};User Id=${DB_USER};Password=${DB_PASS}"  
  }
}

Если переменная окружения не определена, будет использовано значение по умолчанию (если указано).

Загрузка .env файлов

Для автоматической загрузки переменных из файла .env используйте:
