Headless.Domain.LocalPublisher

DI-based implementation of ILocalMessagePublisher for in-process domain event handling.

Problem Solved

Provides in-memory local message publishing that resolves handlers from the DI container, enabling decoupled event-driven architecture within a single process.

Key Features

ILocalMessagePublisher implementation using DI
Automatic handler discovery and resolution
Handler ordering via LocalEventHandlerOrderAttribute
Sync and async publishing support
Scoped handler resolution

Installation

dotnet add package Headless.Domain.LocalPublisher

Quick Start

var builder = WebApplication.CreateBuilder(args);

// Register local message publisher
builder.Services.AddLocalMessagePublisher();

// Register handlers (automatically discovered or explicit)
builder.Services.AddScoped<ILocalMessageHandler<OrderCreatedEvent>, OrderCreatedHandler>();

Publishing Events

public sealed class OrderService(ILocalMessagePublisher publisher)
{
    public async Task CreateOrderAsync(Order order, CancellationToken ct)
    {
        await _repository.AddAsync(order, ct).ConfigureAwait(false);

        await publisher.PublishAsync(new OrderCreatedEvent(order.Id), ct).ConfigureAwait(false);
    }
}

Handling Events

public sealed class OrderCreatedHandler : ILocalMessageHandler<OrderCreatedEvent>
{
    public async Task HandleAsync(OrderCreatedEvent message, CancellationToken ct)
    {
        // Send email, update read model, etc.
    }
}

[LocalEventHandlerOrder(1)] // Execute first
public sealed class AuditHandler : ILocalMessageHandler<OrderCreatedEvent>
{
    public Task HandleAsync(OrderCreatedEvent message, CancellationToken ct)
    {
        // Audit logging
        return Task.CompletedTask;
    }
}

Configuration

No configuration required.
