Quick Reference

Creating Configuration

using Apq.Cfg;

var cfg = new CfgBuilder()
    .AddJsonFile("config.json", level: 0, writeable: false)
    .Build();

Reading Values

// String value
string? value = cfg["App:Name"];

// Typed value
int port = cfg.GetValue<int>("App:Port");

// Check existence
bool exists = cfg.Exists("App:Name");

// Get section
ICfgSection section = cfg.GetSection("Database");

Writing Values

// Set value
cfg.SetValue("App:Name", "NewName");

// Remove value
cfg.Remove("App:TempKey");

// Save changes
await cfg.SaveAsync();

Batch Operations

// Read multiple
var values = cfg.GetMany(new[] { "Key1", "Key2", "Key3" });

// Write multiple
cfg.SetManyValues(new Dictionary<string, string?>
{
    ["Key1"] = "Value1",
    ["Key2"] = "Value2"
});

Configuration Changes

cfg.ConfigChanges.Subscribe(e =>
{
    foreach (var (key, change) in e.Changes)
    {
        Console.WriteLine($"[{change.Type}] {key}");
    }
});
