Feature Highlights

Event driven requeset

Listing all todos as well as create a new todo is fully event driven. The controller publishes a message and returnsa 200 OK. The front end is updated through a SignalR push.

[HttpGet]
[Route("api/todos/")]
public async Task<IActionResult> GetAllTodos()
{
	await PublishAsync(new CreateTodoList {Count = int.MaxValue});
	return Ok(new {success = true});
}

Messages are directed to the right (SignalR) client but using Message Context Forwarding.

Publish/Subscribe with explicit Ack/Nack

The service uses the new way to Acknowledge messages. If not defined, the messages are auto acked.

await busClient.SubscribeAsync<CreateTodo, TodoContext>(async (msg, context) =>
{
	if (msg.Todo == null)
	{
		return new Nack(false);
	}
	var created = await repo.AddAsync(msg.Todo);
	await busClient.PublishAsync(new TodoCreated
	{
		Todo = created
	});
	return new Ack();
});

Fluent configuration

Get even better control over the client. Override configuration with the fluent IPipeContext action

var todo = await BusClient.RequestAsync<TodoRequest, TodoResponse>(new TodoRequest {Id = id},
	ctx => ctx.UseRequestTimeout(TimeSpan.FromSeconds(20))
);
