NoQBus

An async, fast and slim message bus for transparent inproc / outbound messaging

It has

• no queue!
• fully async processing
• parallelization ⇒ every consumer runs it's own task/thread!
• transparent client / server functionality
• immutable records as messages
• no serialization if a message stays on one side!
• advanced filtering of requests or repsonses

Samples

Subscription with no response:

private async Task SubscriberFunc(MyMessage message) {
 //do sth with your message while running on your own task/thread
}

await _messageBus.Subscribe<MyMessage>(SubscriberFunc);

Subscription with response:

private async Task<MyResponse> SubscriberFunc(MyRequest message) {
 //do sth with your message while running on your own task/thread
 return new MyResponse(someResult);
}

await _messageBus.Subscribe<MyRequest, MyResponse>(SubscriberFunc);

Publish fire and forget message:

await _messageBus.Publish(new MyMessage());

Publish and request some responses:

As many can subscribe to the same messages you can get multiple responses.

MyResponse[] responses = await _messageBus.GetResponses<MyResponse>(new MyRequest());

Sample message:

public record MyMessage : MessageBase {
 public string OneOfMyProps { get; init; }
}

Sample request:

public record MyRequest : RequestBase {
 public string OneOfMyProps { get; init; }
}

Sample response:

public record MyResponse : ResponseBase {
 public string OneOfMyProps { get; init; }
}

Request and response with known response/request type

public record MyRequest : RequestBase<MyResponse> {
 public string OneOfMyProps { get; init; }
}

public record MyResponse : ResponseBase<MyRequest> {
 public string OneOfMyProps { get; init; }
}

Starting the Messagebus

Only local

diContainerBuilder.AddNoQMessageBus(); //or servicecollection
//after building the container:
diContainer.Resolve<IMessageBusConfig>().StartLocalNoQMessageBus();
//from now on you can use:
_messageBus = diContainer.Resolve<IMessageBus>();

SignalR server

diContainerBuilder.AddNoQMessageBus(); //or servicecollection
diContainerBuilder.AddNoQSignalRHost(); //or servicecollection
//after building the container:
await diContainer.StartNoQSignalRHost(x => x.UseUrl("http://localhost:5001"));
//from now on you can use:
_messageBus = diContainer.Resolve<IMessageBus>();

SignalR client

diContainerBuilder.AddNoQMessageBus(); //or servicecollection
diContainerBuilder.AddNoQSignalRClient(); //or servicecollection
//after building the container:
await diContainer.StartNoQSignalRClient(x => x.UseUrl("http://localhost:5001"));
//from now on you can use:
_messageBus = diContainer.Resolve<IMessageBus>();
