Design patterns and architectures for building production quality applications using functional programming.Functional Design and Architectureis 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.InFunctional Design and Architectureyou will learn:Designing production applications in statically typed functional languages such as HaskellControlling code complexity with functional interfacesArchitectures, subsystems, and services for functional languagesDeveloping concurrent frameworks and multithreaded applicationsDomain-driven design using free monads and other functional toolsProperty-based, integrational, functional, unit, and automatic whitebox testingFunctional Design and Architecturelays 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.About the technologyFunctional 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 bookFunctional Design and Architectureteaches 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 insideControl code complexity with functional interfacesArchitectures, subsystems, and services for functional languagesDomain-driven design using free monadsProperty-based and automatic whitebox testingRecalibrate OO designs for functional environmentsAbout the readerFor experienced developers who know a functional language.About the authorAlexander Graninis a senior software engineer and architect with more than 15 years of experience.
