The "Krater" is nothing but a copy of a reddit-like app. The project was created for the purpose of learning Domain Driven Design, a Modular Monolith and event driven architecture.
The project uses rush.js to treat each module as a separate package from the node.js perspective.
In order to better understand and implement the application, Domain Driven Design (DDD) was used both from the strategic and tactical side.
When it comes to discovering the domain, getting to know the actors and likely bounded contexts, the Event Storming technique was used.
