Description

Building for maintainability is key to keep development costs low (and developers happy). The second edition of "Get Your Hands Dirty on Clean Architecture" is here to equip you with the essential skills and knowledge to build maintainable software. Building upon the success of the first edition, this comprehensive guide explores the drawbacks of conventional layered architecture and highlights the advantages of domain-centric styles such as Robert C. Martin's Clean Architecture and Alistair Cockburn's Hexagonal Architecture. Then, the book dives into hands-on chapters that show you how to manifest a Hexagonal Architecture in actual code. You'll learn in detail about different mapping strategies between the layers of a Hexagonal Architecture and see how to assemble the architecture elements into an application. The later chapters demonstrate how to enforce architecture boundaries, what shortcuts produce what types of technical debt, and how, sometimes, it is a good idea to willingly take on those debts. By the end of this second edition, you'll be armed with a deep understanding of the Hexagonal Architecture style and be ready to create maintainable web applications that save money and time. Whether you're a seasoned developer or a newcomer to the field, "Get Your Hands Dirty on Clean Architecture" will empower you to take your software architecture skills to new heights and build applications that stand the test of time.

Who is this book for?

This book is for you if you care about the architecture of the software you are building. To get the most out of this book, you must have some experience with web development. The code examples in this book are in Java. If you are not a Java programmer but can read object-oriented code in other languages, you will be fine. In the few places where Java or framework specifics are needed, they are thoroughly explained.

What you will learn

Identify potential shortcomings of using a layered architecture
Apply varied methods to enforce architectural boundaries
Discover how potential shortcuts can affect the software architecture
Produce arguments for using different styles of architecture
Structure your code according to the architecture
Run various tests to check each element of the architecture

What is custom duty/charge?

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order?

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges?

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.

Ein aus meiner Sicht sehr gutes und wichtiges Buch für jeden (Backend-)Entwickler, aber auch Software-Architekten - besonders, aber nicht nur, im Umfeld von MicroServices.Tom versteht es sehr gut die Leute auf unterschiedlichsten Erfahrungen abzuholen. Nachfolgend schafft er es einem die Vorteile der Clean Architecture (Hexagonale Architektur) näherzubringen, um dann final die praktische Umsetzung zu erläutern und mit Beispielen zu belegen. Auch die Vorraussetzungen und potentiellen Probleme werden sehr ausführlich dargelegt und aufgelöst. Gerade dieses ist aus meiner Sicht eine Stärke dieses Buchs, da es einem nicht mit theoretischem Wissen zurücklässt, sondern sehr viele praktische Lösungsschablonen an die Hand gibt.Sehr positiv auch die Ausblicke in die Sicherstellung der Pattern / Architektur-Constraints, so dass auch hier die Softwareerosion proaktiv vermieden, verzögert werden kann.Wenn ich mir noch was wünschen könnte, dann hätte ich gerne ergänzende Beispiele in einer zweiten Programmiersprache.

One of the best books I have ever read. Very helpful to understand the actual structure of a project

mgustav Dec 09, 2023

The book offers a treasure trove of practical and theoretical insights into Clean Architecture. The balanced deliberations on the judicious use of shortcuts make it a standout.

Celil U. Aug 10, 2023

The author provides detailed explanations on how to create maintainable software. To clarify, he offers a comprehensive description of what maintainable software is and the benefits it offers. Through reading about his experiences in previous projects, readers get the impression that the author has devoted significant time to the development of maintainable software architecture.Using an example software project available on GitHub, he demonstrates the process of creating maintainable software, from layered to hexagonal architecture. In doing so, he delves into two principles of SOLID: Dependency Inversion and Single Responsibility. He also elucidates the significance of Domain Driven Design (DDD) and its relevance in crafting a maintainable architecture.After each chapter, the author succinctly explains why the covered content is essential for a maintainable architecture, allowing readers to effortlessly grasp his reasoning.While the author offers valuable insights on creating maintainable software using a simple example, some readers might yearn for guidance on applying these insights to larger projects, depending on their requirements. Nonetheless, the author concludes his book by emphasizing that these tips can and should be customized and incorporated into each organization's software development projects, always bearing in mind the criteria for maintainable software.In summary, this book serves as an insightful guide on constructing maintainable software, replete with valuable hints, guidelines, and code examples. Although the code examples are written in Java + Spring, they are straightforward and can be understood by anyone familiar with object-oriented programming languages. Moreover, even non-native English speakers will find the author's explanations easy to comprehend.

This book gives you very practical but technology agnostic insights on the Hexagonal Architecture style.I especially liked the discussion on shortcuts and tradeoffs on the different aspects which comes with this architectural style.What I especially liked about the second version of the book are the cross references to maintainability at the end of each chapter. I also find the thoughts on horizontal / vertical layering in chapter 13 very insightful and practical relevant.At the very end the author present a very pragmatic architecture style to enable high modularity in software systems with less complex domain and how to evolve it over time -> this was my personal highlight.What I personally missed are some concrete examples about:* Approaches when integrating multiple external systems in an asynchronous manner (especially on the API design of ports) -> command/query vs reactive* Usage of domain events for cross domain communication, but also reporting purposes* Approaches on how to share some common technical aspects (aka shared kernel) between/inside domains / components (there is always some common code ;-))* How to make modularity measurable -> which metrics would you apply and have been proven as practical relevantBut all in all this is by far the best practical lecture on how to structure code in a modular manner which I have read so far !Following the authors guidelines will enable you to transform your legacy software architecture into an evolutionary one :-)
