Routya.ConfigKit 1.0.0

⚙️ Routya.ConfigKit.Generator

🔧 A lightweight, source-generated configuration binder for .NET — just tag your class with [ConfigSection] and go.

✨ Features

• ✅ Compile-time generation of config binding and registration code
• ✅ Supports both IOptions<T> and AddSingleton<T> modes
• ✅ Full support for System.ComponentModel.Annotations
• ✅ No reflection at runtime
• ✅ Drop-in integration with appsettings.json
• ✅ Currently only supports {get; set;} and {get; init;}.

🚀 Getting Started

🛠 Binding Modes | Mode | Behavior | |-------------|----------------------------------------| | Singleton | Registers the instance via AddSingleton<T> | | IOptions | Uses services.Configure<T>() | | Both | Adds both for flexibility |

1. Install package

dotnet add package Routya.ConfigKit.Generator

2. Create your config class

ConfigSection("MyService", ConfigBindingMode.IOptions)

The 'MyService' in ConfigSection is the section name within your configuration (eg. appsettings.json, Azure App Configuration)

{
  "MyService": {
    "RetryCount": 3,
    "UseCaching": false
  }
}

ConfigBindingMode.IOptions

using System.ComponentModel.DataAnnotations;
using Routya.ConfigKit;

[ConfigSection("MyService", mode: ConfigBindingMode.IOptions)]
public partial class MyServiceOptions
{
    [Required]
    public int RetryCount { get; init; }

    public bool UseCaching { get; init; } = true;
}

Generates

public static IServiceCollection AddMyServiceOptions(this IServiceCollection services, IConfiguration configuration)
{
	services.AddOptions<MyServiceOptions>()
			.Bind(configuration.GetSection("MyService"))
			.ValidateDataAnnotations()
			.ValidateOnStart();

	return services;
}

ConfigBindingMode.Singleton

using System.ComponentModel.DataAnnotations;
using Routya.ConfigKit;

[ConfigSection("MyService", ConfigBindingMode.Singleton)]
public partial class MyServiceOptions
{
    [Required]
    public int RetryCount { get; init; }

    public bool UseCaching { get; init; } = true;
}

Generates

 public static IServiceCollection AddMyServiceOptions(this IServiceCollection services, IConfiguration configuration)
 {
     var options = new MyServiceOptions()
     {
         RetryCount = configuration.GetValue<int>("MyService:RetryCount"),
         UseCaching = configuration.GetValue<bool>("MyService:UseCaching"),
     };

     var validationContext = new ValidationContext(options);
     Validator.ValidateObject(options, validationContext, validateAllProperties: true);

     services.AddSingleton(options);

     return services;
 }

3. Register the generated method in your startup

builder.Services.AddMyServiceOptions(builder.Configuration);

📅 Roadmap

• Add support for complex/nested config objects
• {get; private set;}
