Light Messaging Core Boilerplate with Saga

Lightweight core messaging library and boilerplate with RabbitMQ, MassTransit and SagaStateMachine

Link: -

Features:

Provides basic RabbitMQ BUS instance
Includes basic producer & consumer boilerplate
Includes basic model workflow, state machine and sagas

Manuel Usage:

Firstly you have to add these keys in your configuration file.

<appSettings>
	<add key="RabbitMQUri" value="rabbitmq://hostAddress/"/>
	<add key="RabbitMQUserName" value="username"/>
	<add key="RabbitMQPassword" value="password"/>
</appSettings>

Initializing RabbitMQ BUS instance for Producer:

IBusControl busControl = BusConfigurator.Instance.ConfigureBus();
var sendToUri = new Uri("rabbitmqUri/queueName");

ISendEndpoint bus = busControl.GetSendEndpoint(sendToUri).Result;

after RabbitMQ BUS instance initializing then you can use Send method with your queues channel TCommand type.

bus.Send<TCommand>(new
			{
				SomeProperty = SomeValue
			}
		);

RabbitMQ BUS instance using for Consumer:

static void Main(string[] args)
{
	var bus = BusConfigurator.Instance
		.ConfigureBus((cfg, host) =>
			{
				cfg.ReceiveEndpoint(host, "queueName", e =>
				{
					e.Consumer<TCommandConsumer>();
				});
			});

	bus.Start();

	Console.ReadLine();
}

TCommandConsumer could like below:

public class TCommandConsumer : IConsumer<TCommand>
{
    public async Task Consume(ConsumeContext<TCommand> context)
    {
        var command = context.Message;

		//do something...
        await Console.Out.WriteAsync($"{command.SomeProperty}");
    }
}

PS: Publisher and Consumer services must be used same TCommand interface. This case important for MassTransit integration.

There are several options you can set via fluent interface:

.UseRetryPolicy(IRetryPolicy retryPolicyement)
.UseCircuitBreaker(int tripThreshold, int activeThreshold, int resetInterval)
.UseRateLimiter(int rateLimit, int interval)
