⚡ WJb

If you can't explain why a job runs, you don't control your system.

Most background job systems eventually become:

Job
 ↓
Retry
 ↓
Pipeline
 ↓
Middleware
 ↓
???

Then somebody asks:

Why did this run?
Why was it retried?
Who scheduled the next step?
Where is that logic?

And nobody can answer in 30 seconds.

WJb

WJb is an explicit background job engine for .NET.

Job
 ↓
Action
 ↓
ActionResult
 ↓
JobCommand

Every step is visible.

Every transition is explicit.

Every workflow is defined in code.

Example

Workflow:

send-email → log → done

Code:

public sealed class SendEmailAction : JobAction<EmailInput>
{
    public override Task<ActionResult> ExecuteAsync(EmailInput input, CancellationToken ct)
    {
        return Task.FromResult(ActionResults.Next(
            new JobCommand("log",
                new LogInput { Message = $"Email sent to {input.To}" })));
    }
}

The workflow is not hidden.

The action decides what happens next.

Performance

Quick Start

var store = new InMemoryStore();

var wjb = WJbBuilder.Create(store, cfg =>
{
    cfg.AddAction<SendEmailAction>("send-email");
    cfg.AddAction<LogAction>("log");
});

await wjb.EnqueueAsync("send-email",
    new EmailInput { To = "user@test.com" });

await wjb.ExecuteLoopAsync();

What Makes WJb Different?

✅ Explicit workflows

✅ Explicit retries

✅ Explicit next-step scheduling

✅ Constructor injection

✅ Strongly typed actions

✅ Business logic in code

❌ Hidden pipelines

❌ Hidden orchestration

❌ Workflow magic

Mental Model

Action       = Business Logic

ActionResult = Outcome

JobCommand   = Next Step

Executor     = Runner

Store        = Persistence

That's it.
