Plumber

Another weapon from the MSL Armory

Middleware pipelines for host-free .NET projects. Plumber brings the ASP.NET Core middleware model — a request, a response, and a chain of steps with dependency injection and configuration — to .NET projects that run without a host: console apps, AWS Lambdas, Azure Functions, queue consumers, file processors, and similar workloads.

The wiki is the full documentation: concepts, a tutorial, per-type reference, and deployment recipes.

Packages

  • MSL.Plumber.Pipeline — the core builder, handler, middleware, and request context. See Pipeline.
  • MSL.Plumber.Pipeline.Testing — PlumberApplicationFactory for exercising a real pipeline in tests. See Testing.
  • MSL.Plumber.Serilog.Extensions — per-request Serilog request logging. See Serilog Extensions.
  • MSL.Plumber.Diagnostics — per-request OpenTelemetry tracing and metrics middleware. See Diagnostics.

Install

dotnet add package MSL.Plumber.Pipeline

Plumber targets .NET 10.

Hello, World

using Plumber;

using var handler = RequestHandlerBuilder
    .Create<string, string>()
    .Build();

handler.Use((context, next) =>
{
    context.Response = $"Hello, {context.Request}!";
    return next(context);
});

var greeting = await handler.InvokeAsync("World");
Console.WriteLine(greeting); // Hello, World!

A Plumber application has four pieces: a builder, the handler it builds, one or more middleware, and an InvokeAsync call. Each invocation gets its own dependency injection scope and cancellation token.

Where to go next

  • New to middleware pipelines? Start with Concepts, then the Tutorial.
  • Know the shape already? Jump into Building a pipeline, Middleware, and Request lifecycle.
  • Looking for a specific scenario? Browse the recipes — AWS Lambda, Azure Functions, queue consumers, webhooks, and more — from the wiki home.
  • Migrating from an earlier version? See Migration. v5 makes no breaking changes; v4 and v3 are covered with before-and-after examples.

Showing the top 3 NuGet packages that depend on MSL.Plumber.Pipeline:

Package Downloads
MSL.Plumber.Serilog.Extensions

Serilog middleware for the Plumber pipeline framework: structured per-request logging through a Serilog DiagnosticContext, with configurable level, message template, and enrichment. Completion events carry the active trace's TraceId and SpanId, so logs correlate with your Plumber.Diagnostics spans.
MSL.Plumber.Pipeline.Testing

WebApplicationFactory-style integration testing for Plumber pipelines. PlumberApplicationFactory bootstraps your application's real builder and pipeline, then lets tests override services, configuration, and logging before the pipeline is built.
MSL.Plumber.Diagnostics

OpenTelemetry tracing and metrics for the Plumber pipeline framework, with no OpenTelemetry SDK dependency: per-request spans and metrics are emitted through the in-box ActivitySource and Meter primitives, so you export to any backend — OTLP, Jaeger, Prometheus, or the console — with your own SDK setup. Configurable per-request enrichment.
