Easy, Service Oriented, Asynchronous Messaging and Queueing for .Net

View project on GitHub

RestBus is a high performance messaging library that enables you to consume ASP.NET Core, Web API and ServiceStack service endpoints via RabbitMQ.
With RestBus, queuing or sending a message asynchronously is as simple as:

var amqpUrl = "amqp://localhost:5672"; //AMQP URI for RabbitMQ server
var serviceName = "samba"; //The unique identifier for the target service

var client = new RestBusClient(new BasicMessageMapper(amqpUrl, serviceName));

//Call the /hello/random endpoint
var response = await client.GetAsync("/hello/random");

Does that look familiar?
If you're conversant with .NET's HttpClient class, you'll be right at home with the RestBusClient class. In fact they both derive from the same base class.

The /hello/random endpoint is an ordinary web service endpoint in an ASP.NET Core, Web API or ServiceStack service.
RestBus routes the request over RabbitMQ, invokes the endpoint and returns the response, without ever hitting the HTTP transport.

Why do I need this?

Using RabbitMQ from .NET can be a frustrating experience. RestBus makes it ridiculously easy.

Getting Started


Zero Configuration

You don't need to configure the RabbitMQ server. RestBus automatically creates exchanges, queues and other resources as needed.

Use your Existing Web Services

Your services can still be consumed via HTTP while supporting RabbitMQ calls or you can turn off the HTTP interface.
Migrating your services to a message oriented architecture is as easy as writing a few lines of code.

Asynchronous Messaging

Enjoy optimum efficiency in service request processing as endpoints can now be invoked asynchronously.

Horizontal scaling

Scaling your services horizontally is as easy as launching new instances.

It's Fast

RestBus compares very favorably with other messaging libraries, and is the fastest library in many cases.

Roll your own MessageMapper class for custom messaging behavior.

How it works

RestBus follows the RPC messaging style. For more details, see How It Works.
