I am working on a program in golang, which I am sructuring based on Hexagonal Architecture. I think I have my head wrapped mostly around the idea, but there is something I just can't figure out. Th...

As I understand it, one of the key rules of Hexagonal Architecture is how the Domain Layer is isolated from everything except the Application Layer which works with it (the Domain Layer has no depe...

I am confused about where to handle domain events in an application that is based on the hexagonal architecture. I am talking about the bounded-context-internal domain events, and not about inter-c...

I'm trying to get used to hexagonal architecture and can't get how to implement common practical problems, already realized with different approaches. I think my core problem is to understand level...

I am creating a banking application. Currently, there is one primary service, the transaction service. This service allows getting transactions by id, and creating transactions. In order to create ...

Several sources claim that process managers do not contain any business logic. A Microsoft article for example says this: You should not use a process manager to implement any business logic in yo...

Considering the Clean Architecture definition, and especially the little flow diagram describing relationships between a controller, a use case interactor, and a presenter, I'm not sure if I correc...

I'm reading a lot about hexagonal architecture, but in all the examples that i'm looking, all folders and class ubication are different, and this looks a bit confusing to me. I've done a simple sp...

I am asking you who know well and have experience in building a software using any layered architecture (onion, hexagonal, clean, etc.). Whenever I google about the software architecture, people ha...

trying to figure out some concepts and haven't been able to understand What is a use-case in the Ports and Adapters architecture ? What an implementation of a use-case would look like ? What ...

Is there any difference between them (onion | hexagonal), from my understanding they are just the same, they focus upon the domain which is at the core of the application and should be technology /...

Should Use Cases or Application Services have interfaces and implementations when following a hexagonal architecture with ddd principles? For example, the use case "delete a video", shoul...

What I usually do in my applications is that I create all my services/dao/repo/clients using factory methods class Service: def init(self, db): self._db = db @classmethod def from_env(cls): ...

I was wondering how the hexagonal architecture relates to microservices. Do the microservices all go into the core of the hexagon? Or does each microservice get a hexagonal architecture? Or is it b...

I'm reading Vaughn Vernon Book - Implementing Domain Driven Design. There is an example of a Project Management Application. There are aggregates like BacklogItem, Sprint, etc. If I have BacklogIte...

I'm going to start a new project to learn spring boot, spring data, and the hexagonal architecture. From my understanding the hexagonal architecture aims to separate the core or domain layer from t...

As I was reading a lot lately regarding the Ports and Adapters architecture, I stumbled upon this piece of code as a part of an application that was build following the above mentioned architecture...

After reading different sources about the Ports & Adapters architecture including Alistair Cockburn's original article I am still not sure about the definite meaning of the terms "port" and "ad...

I've been reading a lot a bout hexagonal architecture and I do get most of the concepts (well, I hope I do), I didn't find any example of that architecture use-case wise. Let's say that my applica...

I attended a meetup yesterday on scaling Rails, and one topic was Hexagonal Rails. However, I've only been doing Rails for a year, and am really comfortable (maybe too comfortable) with the MVC str...

I try to design a web based application in Ruby. I have developed a simple core application implementing DCI paradigm in hexagonal architecture without framework and database. There are small hexag...

Alistair Cockburn introduced a Hexagonal architecture, now it is called Ports and Adapters pattern. In my understanding, the concept is similar to n-layer architecture where one layer depends on th...
