Implementing Clean Architecture - Make it scream

How do I make my architecture “scream”?

According to Uncle Bob an architecture “screams” when it clearly expresses its core business purpose. The top level folder structure, the project/DLL names and the namespaces should express business aspects rather than frameworks or other details.

Athena is a web application implemented in ASP.NET MVC. But is this important? I could switch to Ruby on Rails or Node.js - it wouldn’t make any difference for the business. Why do we let such details impact our project structure so often?

Book: Clean Architecture

I did! As with every book from Uncle Bob’s it is motivating and inspiring, right?

So let’s take his ideas and realize these in our projects to gain what he is promising!

But how do I start? How do I transform an existing code base - following a layered (web) architecture - into the Clean Architecture?

The second habit

This week I had a discussion with a colleague of mine about stakeholder conform communication. The content of the discussion reminded me about the “2. Habit: Begin with the end in mind”.

MVVM pattern and dialogs

Every now and then I come across questions on how to handle dialogs in MVVM pattern with WPF. Honestly, most of the solution proposals I don’t like as they - from my perspective - somehow “violate” the MVVM pattern.

Here is how I handle dialogs with MVVM pattern …

Book Review: Domain-Driven Design

After having it on the reading list for a long time and having been reminded to read it by several other sources in the recent weeks I finally took the time get through

Book: Domain-Driven Design: Tackling Complexity in the Heart of Software

Domain-Driven Design: Tackling Complexity in the Heart of Software

First, I have to admit: not an easy read - at least not for me. Of course the book is well structured and for sure Eric knows what he is talking about but for me his language is more challenging to read as e.g. Uncle Bob - more advanced English, longer sentences … but finally i made it ;-)

Now lets focus on content!

Book Review: Clean Architecture

Book: Clean Architecture

Clean Architecture

As with every book by Uncle Bob it was fun to read it … so I finished it in 2 days ;-)

As the title states and in contrast to his other recent books this book is really focusing on architecture. He clearly describes what architecture is about and what good architecture is, from his perspective.

Even if you have read his Clean Architecture article already I strongly recommend reading the book. It goes much more into details and so brings more insights relevant when you try realizing Clean Architecture in one of you next projects …

Book Review: SurviveJS

After having spent the recent weeks and months getting deeper into web development and especially into full stack MicroServices (including non-monolith front-ends) I realized that it is time to read a book about “client side development” in general to get a stronger foundation on state of the art development setups.
