What is this

Message bus is a library (or a collection of libraries) used by Dáme jídlo for separating different layers and contexts within it's monolithic backend application.

In Dáme jídlo the main purpose was to

• create an application layer with commands/handlers (e.g. "place order") to separate domain logic from the rest of the application
• get rid of tight coupling of different contexts by using asynchronous event subscribers for secondary tasks (e.g. send notification to customer on order placed)

The core is a general message bus. It can be used in different ways:

• as a command bus, handling commands synchronously
• as a event dispatching system, with the ability to plug-in asynchronous ways to handle events in different subscribers

The message bus functionality can be enhanced with middleware, e.g.:

• logging
• transaction management
• sync/async handling
