JustSaying.Naming.EnvironmentServiceNaming 8.1.21

EnvironmentServiceNaming

This is a page for JustSaying v8 to add a naming convention based on environment & service name. It also has an extra method for defining point to point queues. Use the v7 branch for the v7 release of JustSaying.

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.
