Reactive, strongly-typed configuration layering for .NET
Zero ceremony configuration that updates itself. Define a class, add a rule, inject it — no IOptions<T> wrappers, no Configure<T>() calls.
Install
dotnet add package Cocoar.Configuration # Core library (console apps)
dotnet add package Cocoar.Configuration.DI # + Microsoft.Extensions.DI
dotnet add package Cocoar.Configuration.AspNetCore # + health endpoints, feature flags
You only need one — each includes everything above it. Requires .NET 8+.
Quick Start
var builder = WebApplication.CreateBuilder(args);
builder.AddCocoarConfiguration(c => c
.UseConfiguration(rule => [
rule.For<AppSettings>().FromFile("appsettings.json"),
rule.For<AppSettings>().FromEnvironment("APP_"),
]));
var app = builder.Build();
// Inject directly — no wrapper
app.MapGet("/settings", (AppSettings settings) => new
{
settings.AppName,
settings.MaxRetries
});
app.Run();
Key Features
- Zero Ceremony — Define a class, add a rule, inject it. Just your POCO.
- Reactive by Default —
IReactiveConfig<T>updates automatically when sources change. - Atomic Updates —
IReactiveConfig<(T1, T2)>guarantees consistent snapshots across types. - Explicit Layering — Rules execute in order, last write wins. File, environment, CLI, HTTP.
- Memory-Safe Secrets —
Secret<T>with automatic zeroization and X.509 hybrid encryption. - Feature Flags & Entitlements — Strongly-typed, source-generated, with expiry health monitoring.
- Health Monitoring — Per-rule status tracking, OpenTelemetry metrics, ASP.NET Core health checks.
- Compile-Time Validation — Roslyn analyzers catch configuration errors in your IDE.
- First-Class Testing —
CocoarTestConfigurationwithAsyncLocal<T>isolation.
