Design patterns and architectures for building production quality applications using functional programming, with examples in Haskell and other FP languages. 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 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. 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. 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. 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.
