I am thrilled to announce that my book, Functional Design and Architecture, has just been released by @ManningBooks! FINALLY RELEASED!!! 😃😃😃😄😊😊❤️❤️❤️❤️❤️❤️ This has been a long journey, and I sincerely hope this book will make a significant contribution to the functional programming world. 🎇🎇 ❓ Who is this book for? It's for all developers interested in practical functional programming. This book is useful for software architects, senior developers, and everyone else. The model language is Haskell, but the ideas are universal and applicable to languages like Scala, OCaml, F#, and even C# and C++. ❓What is this book about? It’s about applying an engineering approach to functional programming. Design patterns, design principles, application architectures, best practices, approaches, and deep ideas—all combined into a comprehensive and highly consistent methodology for building real-world applications. 📔 Functional Design and Architecture is structured, consistent, well-written, and approachable. I’ve made a special effort to ensure the content is accessible to a wide audience. The narrative is engaging, free of jargon and complex mathematics, and progresses in a friendly, gradual manner. 💡 The ideas are universal; some were known before, but many were developed throughout this project. There was a significant knowledge gap, and this book covers much of it for our benefit. A titanic amount of work went into this book. Specifically, the following were created: 🟠 A full-fledged application framework, Hydra; 🔴 A proof-of-concept platform for creating spaceship management scenarios; 🟡 The methodology of Functional Declarative Design, covering various aspects of design and software architecture in functional programming; 🟢 A unique architectural approach, Hierarchical Free Monads; 🔵 A multitude of new design patterns, approaches, and practices, in addition to those that already existed; 🟣 Several demo applications, included both in the book and in the Hydra framework; 🟤 A wealth of accompanying material: articles, talks, and side projects; ⚪️ And of course, these ideas have been successfully tested in practice in several places. You'll also find many links to other valuable resources in this book because the subject is very broad and deep. I am especially grateful to all those who initiated this movement toward the practical application of functional programming. I stand on the shoulders of giants and deeply appreciate their contributions. On the cover, you’ll find testimonials from these distinguished individuals: 🟡 @ScottWlaschin, author of Domain Modeling Made Functional (Pragmatic Bookshelf) 🟤 @debasishg, author of Functional and Reactive Domain Modeling and DSLs in Action (both from Manning) 🟣 @VBragilevsky @_bravit , author of Haskell in Depth (Manning) I hope you enjoy the book as much as I enjoyed writing it. Bon voyage!
