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. 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
