AppSettings.json va AppSettings.Development.json

ASP.NET Core’da konfiguratsiya (sozlamalar) appsettings.json fayli orqali saqlanadi.
Bu fayllar json formatida bo‘lib, unda ConnectionString, Logging, API sozlamalari, Custom Settings kabi umumiy parametrlar saqlanadi.

Asosiy fayl: appsettings.json

Loyihaning barcha muhitlarida umumiy ishlatiladi (Development, Staging, Production).

Masalan, asosiy ulanish satri yoki loglash darajasi.

{
  "ConnectionStrings": {
    "DefaultConnection": "Server=ProdServer;Database=ProdDB;User=sa;Password=123;"
  },
  "Logging": {
    "LogLevel": {
      "Default": "Information"
    }
  }
}

Muhitga xos fayl: appsettings.Development.json

Bu fayl faqat Development (dasturchilar muhitida) ishlatiladi.

Unda ishlab chiqish uchun qulayroq sozlamalar yoziladi. Masalan, LocalDB ulanishi yoki loglarni batafsilroq chiqarish.

{
  "ConnectionStrings": {
    "DefaultConnection": "Server=(localdb)\\mssqllocaldb;Database=DevDB;Trusted_Connection=True;"
  },
  "Logging": {
    "LogLevel": {
      "Default": "Debug",
      "Microsoft": "Warning"
    }
  }
}

⚡ Muhitni aniqlash: ASP.NET Core avtomatik ravishda ASPNETCORE_ENVIRONMENT o‘zgaruvchisiga qarab to‘g‘ri faylni yuklaydi:

Development → appsettings.Development.json

Staging → appsettings.Staging.json

Production → appsettings.Production.json

👉 Bu orqali bir xil kodni turli muhitlarda sozlamalarni o‘zgartirmasdan ishlatish mumkin.
