JustSaying.Naming.EnvironmentServiceNaming 7.0.2

EnvironmentServiceNaming

This is a page for JustSaying v7 to add a naming convention based on environment & service name. It also has an extra method for defining point to point queues.

What it looks like

Environment and service name are converted to lower case and any non-alphanumeric characters are removed.

Topic queues:

{environment}-{service}-{messageType}

Topic name:

{environment}-{messageType}

Point to point queues:

{environment}-p2p-{messageType}

How to use

Set up default naming conventions

This will set up the default naming conventions for all queues and topics.

var environment = "test";
var serviceName = "my-service";

var namingStrategy = new EnvironmentNamingStrategy(environment, serviceName);

container.RegisterInstance<IQueueNamingConvention>(queueNamingConvention);
container.RegisterInstance<ITopicNamingConvention>(topicNamingConvention);

var builder = new MessagingBusBuilder()
    // Other configuration here
    .Messaging(
        x =>
        {
            // Other configuration here
            x.WithQueueNamingConvention(queueNamingConvention);
            x.WithTopicNamingConvention(topicNamingConvention);
        });

To use the point to point naming convention, the subscription / publisher needs to be setup during configuration:

    builder.Subscriptions(
        x =>
        {
           
            x.ForQueue<TestMessagePointToPoint>(
                cfg =>
                {
                    cfg.ConfigurePointToPointQueue(Environment);
                });
        }
    );
    
     builder.Publications(
        x =>
        {
            x.WithQueue<TestMessagePointToPoint>(cfg => cfg.ConfigurePointToPointPublisher(Environment));
        });

If individual p2p queues aren't configured as above, then it will default to:

{environment}-{service}-{messageType}

Additional Notes

There are helper extension methods for configuration which are used above:

ConfigurePointToPointPublisher ConfigurePointToPointQueue

In a similar vein exists ConfigureTopic which provides a similar interface for configuring subscriptions, but is not strictly needed for configuring naming conventions.
