Functional Design and Architecture - by Alexander Granin (Paperback)

About the Book

Functional Design and Architecture is a comprehensive guide to software engineering using functional programming. Inside, you'll find cutting-edge functional design principles and practices for every stage of application development. There's no abstract theory--you'll learn by building exciting sample applications, including an application for controlling a spaceship and a full-fledged backend framework.
You'll explore functional design by looking at object-oriented principles you might already know, and learn how they can be reapplied to a functional environment. By the time you're done, you'll be ready to apply the brilliant innovations of the functional world to serious software projects

Book Synopsis

Design patterns and architectures for building production quality applications using functional programming.

Functional Design and Architecture is a pioneering guide to software engineering using Haskell and other functional languages. In it, you'll discover Functional Declarative Design and other design principles perfect for working in Haskell, PureScript, F#, and Scala.

In Functional Design and Architecture you will learn:

- Designing production applications in statically typed functional languages such as Haskell
- Controlling code complexity with functional interfaces
- Architectures, subsystems, and services for functional languages
- Developing concurrent frameworks and multithreaded applications
- Domain-driven design using free monads and other functional tools
- Property-based, integrational, functional, unit, and automatic whitebox testing

Functional Design and Architecture lays out a comprehensive and complete approach to software design that utilizes the powerful and fascinating ideas of functional programming. Its examples are in Haskell, but its universal principles can be put into practice with any functional programming language. Inside, you'll find cutting-edge functional design principles and practices for every stage of application development, from architecting your application through to running simple and maintainable tests.

Purchase of the print book includes a free eBook in PDF and ePub formats from Manning Publications.

About the technology

Functional programming affects every aspect of software development, from how you write individual lines of code to the way you organize your applications and data. In fact, many standard OO patterns are unsuitable or unnecessary for FP applications. This book will reorient your thinking to align software design with a functional programming style. The examples are in Haskell, but the ideas are universal.

About the book

Functional Design and Architecture teaches you how to design software following the unique principles of functional programming. You'll explore FP-first paradigms like Functional Declarative Design by building interesting applications, including a fun spaceship control simulator and a full-fledged backend framework. This is an opinionated book and you may disagree on some points. But we guarantee it will make you think in a fresh way about how you design software.

What's inside

In it, you'll discover Functional Declarative Design and other design principles perfect for working in Haskell, PureScript, F#, and Scala. about the technology Functional programming offers a powerful alternative to object-oriented programming that helps tackle the complexities of large-scale software. Entrenched design patterns and architectural principles made for OOP are poorly suited for creating large-scale functional applications. This book lays out new methodologies, principles, and architectures optimized for high-level software design using functional languages. about the book Functional Design and Architecture is a comprehensive guide to software engineering using functional programming.

Review Quotes

'The functional scene needs to have this kind of book, one with not only theoretical functional domain chapters, but with practice in the area too.' German Gonzalez-Morris 'A much desired bridge between the theoretical understanding of functional programming and the ability to design and construct entire software systems using it.' Makarand Deshpande 'A very detailed look at functional design with rich examples.' Charles Earl 'A great book which show you different aspects of Haskell which are very uncommon to see in other articles or books.' Andres Sacco 'If you want to design real world applications in Haskell with a focus on elegance, flexibility, and scalability, you must read this book.' David Paccoud
