Codekali.Net.Config.UI

A plug-and-play .NET 8 library that provides a browser-based GUI for managing appsettings.json configuration files in any .NET solution.

✨ Features

📂 Auto-detect all appsettings*.json files at runtime
🌳 Tree view — expand, edit, add, delete inline with full array support
🔢 Array editing — expand arrays, append items, remove items by index
✏️ Raw JSON editor powered by Monaco (VS Code engine) with syntax highlighting, bracket matching, and Ctrl+S to save
💬 Comment preservation — // and /* */ comments survive every save
⇄ Move / Copy configuration keys between environment files
⊞ Side-by-side diff comparing any two environment files
🔄 Hot reload detection — banner notification when a file changes externally
💾 Never auto-saves — all changes require an explicit save action
🔒 Sensitive value masking (password, secret, token, apikey)
🌙 Dark / Light mode toggle
🔐 Development-only by default — optional access token or ASP.NET Core Authorization policy

🚀 Quick Start

1. Install

dotnet add package Codekali.Net.Config.UI

2. Register services

// Program.cs
builder.Services.AddConfigUI();

3. Activate middleware

app.UseConfigUI();

4. Open your browser

https://localhost:5001/config-ui

⚙️ Configuration

builder.Services.AddConfigUI(options =>
{
    options.PathPrefix            = "/config-ui";
    options.AccessToken           = "your-secret-token";     // simple token auth
    options.AuthorizationPolicy   = "ConfigUIAccess";         // or ASP.NET Core policy
    options.AllowedEnvironments   = ["Development","Staging"];
    options.MaskSensitiveValues   = true;
    options.ReadOnly              = false;
    options.EnableAutoToken       = false;                    // auto-generate token on first run
    options.EnableHotReloadDetection = true;
    options.ConfigDirectory       = null;                     // defaults to CWD
});

Authorization policy example

builder.Services.AddAuthorization(o =>
    o.AddPolicy("ConfigUIAccess", p => p.RequireRole("Admin")));

app.UseConfigUI(options => options.AuthorizationPolicy = "ConfigUIAccess");

Auto token generation

builder.Services.AddConfigUI(options => options.EnableAutoToken = true);
// Token is generated on first run and written to Properties/launchSettings.json
// as CONFIGUI_ACCESS_TOKEN. Subsequent runs load it from the environment variable.

IOptions reload guidance

⚠️ Changes written by the Config UI take effect at runtime only when consuming code uses IOptionsSnapshot<T> (per-request) or IOptionsMonitor<T> (singleton-safe) rather than IOptions<T> which snapshots at startup.

Access token is checked via:

Header: X-Config-Token: your-secret-token
Query string: ?token=your-secret-token

🔐 Security

The middleware returns 404 when accessed outside an allowed environment — it does not leak its existence. For production usage:

Set AllowedEnvironments explicitly
Always set an AccessToken
Consider putting the path behind a VPN or internal network
