Raycynix.Extensions.Messaging.RabbitMQ

Raycynix.Extensions.Messaging.RabbitMQ contains the RabbitMQ transport integration for Raycynix messaging.

What it contains

• AddRabbitMq(...)
• RabbitMqMessagingConfiguration
• RabbitMqExchangeConfiguration
• RabbitMqQueueConfiguration
• RabbitMqRetryConfiguration
• RabbitMqDeadLetterConfiguration
• RabbitMQ-backed IMessagePublisher
• automatic exchange, queue, binding, and dead-letter topology bootstrap
• message publishing to RabbitMQ exchanges using MessageEnvelope<TMessage>.Destination as the routing key

What it does not contain

• RabbitMQ consumer hosted services
• retry execution pipeline
• poison-message processing workers
• outbox persistence
• inbox/idempotency storage

Usage

Example appsettings.json:

{
 "RabbitMqMessagingConfiguration": {
 "Host": "localhost",
 "Port": 5672,
 "Exchange": {
 "Name": "integration.events",
 "Type": "topic"
 },
 "Queue": {
 "Name": "orders.created",
 "PrefetchCount": 16
 },
 "DeadLetter": {
 "Enabled": true,
 "Exchange": "integration.dlx",
 "Queue": "integration.dlq",
 "RoutingKey": "dead-letter"
 }
 }
}

Register the transport:

builder.Services.AddRaycynixMessaging(builder.Configuration)
 .AddRabbitMq(builder.Configuration);

Publish to RabbitMQ:

public class OrderPublisher(
 IMessageEnvelopeFactory envelopeFactory,
 IMessagePublisher messagePublisher)
{
 public async Task PublishAsync(string orderId, CancellationToken cancellationToken)
 {
 var envelope = envelopeFactory.Create(
 new OrderCreatedMessage(orderId),
 destination: "orders.created",
 format: MessageFormat.Json);

 await messagePublisher.PublishAsync(envelope, cancellationToken);
 }
}

The package declares the configured exchange and queue on first use, binds the queue using the queue name as the routing key, and publishes messages with the envelope destination as the routing key.

Published AMQP properties include:

• MessageId
• CorrelationId
• ContentType
• contract/version headers from the base messaging layer
