🌱 Kern

⚠️ Warning: This library is under active development.

APIs, structures, and behaviors may change without notice. Not recommended for production use until a stable version is released.

Kern is a modular utility library for .NET that simplifies core backend patterns like asynchronous pipelines, concurrent-safe queues, AWS S3 access, and error modeling. It also offers clean ASP.NET Core integration for standardized responses and FluentValidation filtering.

✨ Features

🧠 Pipeline

A simple, composable pipeline runner for chaining asynchronous processing steps with support for early exits via PipelineResult.

var pipeline = Pipeline
    .Create<string>()
    .AddStep(async input =>
    {
        if (string.IsNullOrWhiteSpace(input))
            return PipelineResult<string>.Fail(new InvalidInputError("Empty input"));

        return PipelineResult<string>.Success(input.ToUpper());
    });

var result = await pipeline.Run("hello");

📥 Queue

Thread-safe task queue manager that allows parallel processing by group but ensures serial execution within the same group, ideal for background job orchestration.

await queue.QueueTaskAsync<SomeTask>();

☁️ S3 Helper

Abstraction over AWS S3 for uploading, downloading, and deleting objects — supports both streams and file paths, and can generate presigned URLs.

await s3.GetObjectAsync(objectName);
