ConfigurationUi 1.0.1

ConfigurationUi

ConfigurationUI is .Net library for managing Asp.Net Core configuration.
It can parse configuration schema from arbitrary .Net type and generate web-page for displaying/editing configuration in user-friendly manner.
ConfigurationUI is fully integrated with with built-in asp.net core configuration Microsoft.Extensions.Configuration, so developers don't have to change existing code, just continue using well-known patterns: OptionsMonitor<T>, IConfiguration, etc ...

Installation & Setup

Using ConfigurationUI is very simple, it is done in 4 steps:

1. Install nuget package ConfigurationUi
2. Create class(es) for describing your application configuration (if not already have):

   public class Settings
   {
     public string StringSetting { get; set; }
     public int IntegerSetting { get; set; }
     public bool BooleanSetting { get; set; }
     public SettingSubSection SettingsSubSection { get; set; }
   }
   
   public class SettingSubSection
   {
       public string StringSetting { get; set; }
       public MyEnum EnumSetting { get; set; }
       public bool BooleanSetting { get; set; }
       public string[] ArraySetting { get; set; }
   }
   
   public enum MyEnum { FirstValue, SecondValue }
   

3. Modify Program.cs and insert .AddConfigurationUi() method call:

   public class Program
   {
       public static void Main(string[] args)
       {
           CreateHostBuilder(args).Build().Run();
       }
   
       public static IHostBuilder CreateHostBuilder(string[] args) =>
           Host.CreateDefaultBuilder(args)
               .AddConfigurationUi<Settings>("settings.json") // insert this line
               .ConfigureWebHostDefaults(webBuilder => { webBuilder.UseStartup<Startup>(); });
   }
   

4. Modify Startup.Configure method and add configuration middleware with app.UseConfigurationUi("/configuration"):

   public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
   {
       if (env.IsDevelopment())
       {
           app.UseDeveloperExceptionPage();
       }
   
       app.UseConfigurationUi("/configuration"); // insert this line
   
       app.UseHttpsRedirection();
   
       app.UseRouting();
   
       app.UseAuthorization();
   
       app.UseEndpoints(endpoints => { endpoints.MapControllers(); });
   }
   

It's done. Navigate to /configuration in browser and you will see configuration editor page:

Important Notes

• Library does not support authorization out of box yet. Make sure to place some custom authorization/authentication middleware before app.UseConfigurationUi("/configuration"); so configuration endpoint will not be accessible to everyone
• Currently web editor does not support or may not work as expected for following .Net types:
  • Dictionaries
  • FlagsAttribute decorated enums
  • Nullable value types
