SummaryFunctional and Reactive Domain Modeling teaches you how to think of the domain model in terms of pure functions and how to compose them to build larger abstractions. Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications. About the TechnologyTraditional distributed applications won't cut it in the reactive world of microservices, fast data, and sensor networks. To capture their dynamic relationships and dependencies, these systems require a different approach to domain modeling. A domain model composed of pure functions is a more natural way of representing a process in a reactive system, and it maps directly onto technologies and patterns like Akka, CQRS, and event sourcing. About the BookFunctional and Reactive Domain Modeling teaches you consistent, repeatable techniques for building domain models in reactive systems. This book reviews the relevant concepts of FP and reactive architectures and then methodically introduces this new approach to domain modeling. As you read, you'll learn where and how to apply it, even if your systems aren't purely reactive or functional. An expert blend of theory and practice, this book presents strong examples you'll return to again and again as you apply these principles to your own projects. What's InsideReal-world libraries and frameworksEstablish meaningful reliability guaranteesIsolate domain logic from side effectsIntroduction to reactive design patternsAbout the ReaderReaders should be comfortable with functional programming and traditional domain modeling. Examples use the Scala language. About the AuthorSoftware architect Debasish Ghosh was an early adopter of reactive design using Scala and Akka. He's the author of DSLs in Action, published by Manning in 2010.Table of ContentsFunctional domain modeling: an introductionScala for functional domain modelsDesigning functional domain modelsFunctional patterns for domain modelsModularization of domain modelsBeing reactiveModeling with reactive streamsReactive persistence and event sourcingTesting your domain modelSummary - core thoughts and principles | Functional And Reactive Domain Modeling by Debasish Ghosh, Paperback | Indigo Chapters
