Jakapil.Capture

Jakapil Capture is an ASP.NET Core middleware SDK that captures HTTP traffic from running .NET APIs. You add it to your application as a single line of middleware; it captures incoming requests, outgoing responses, and correlation signals in the background — without blocking the request path — and exports them to a Jakapil collector.

The captured traffic is turned into self-verifying test scenarios on the Jakapil side. The middleware is designed to be safe under production load: the response always streams to the client without buffering, the capture copy is bounded, and the queue drops the oldest entries under backpressure (it never blocks the request pipeline).

Installation

dotnet add package Jakapil.Capture

Usage

Register the service and add the middleware to the pipeline in Program.cs:

builder.Services.AddJakapilCapture(
    ingestKey: builder.Configuration["Jakapil:Capture:IngestKey"]!,
    collectorUri: "https://collector.jakapil.example");

// ...

app.UseJakapilCapture();

ingestKey is your ingest key and is sent to the collector verbatim in the X-Jakapil-Key header — so it must be supplied only through an environment variable / secret and never hard-coded. collectorUri is the collector address where captured interactions are sent.

If you need finer control, you can use the overload that takes an Action<JakapilCaptureOptions>:

builder.Services.AddJakapilCapture(options =>
{
    options.IngestKey = builder.Configuration["Jakapil:Capture:IngestKey"]!;
    options.CollectorUri = "https://collector.jakapil.example";
    options.SampleRate = 0.25;
});

Configuration options

Option Type Default Description
Enabled bool true Main on/off switch. When false, the middleware is a pure passthrough.
SampleRate double 1.0 The fraction of requests to capture, [0, 1]. 1.0 = capture everything.
CollectorUri string? null The root address of the collector where captured interactions are sent. If left empty, the export worker stays idle.
IngestKey string? null The raw ingest key sent to the collector in the X-Jakapil-Key header.
MaxInlineBodyBytes int 1048576 (1 MiB) Bodies at or below this size are captured inline; larger ones are truncated and flagged as Truncated.

Other settings (MaxCapturedResponseBytes, StreamingContentTypes, QueueCapacity, SensitiveHeaderNames, CorrelationHeaderNames, ExportBatchMaxItems, ExportFlushIntervalSeconds) ship with sensible defaults; see the JakapilCaptureOptions XML documentation comments for details.
