Develop the mindset of building maintainable solutions instead of taking shortcuts

Book Description

We would all like to build software architecture that yields adaptable and flexible software with low development costs. But, unreasonable deadlines and shortcuts make it very hard to create such an architecture.

Get Your Hands Dirty on Clean Architecture starts with a discussion about the conventional layered architecture style and its disadvantages. It also talks about the advantages of the domain-centric architecture styles of 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. You'll also learn what shortcuts produce what types of technical debt and how, sometimes, it is a good idea to willingly take on those debts.

After reading this book, you'll have all the knowledge you need to create applications using the hexagonal architecture style of web development.

What you will learn

Identify potential shortcomings of using a layered architecture
Apply methods to enforce architecture boundaries
Find out how potential shortcuts can affect the software architecture
Produce arguments for when to use which style of architecture
Structure your code according to the architecture
Apply various types of tests that will cover each element of the architecture

Who this book is 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.
