A progressive guide to help you kick-start your Scala 2.13 journey.Key FeaturesThis comprehensive guide gets straight to the advanced programming concepts in ScalaGet a detailed coverage of Lightbend Lagom—the latest microservices framework from LightbendUnderstand the Akka framework and learn Reactive Programming with ScalaBook DescriptionToday’s Scala is quite different from its earlier versions. The second version of the language is more than twelve years old and has undergone multiple changes related to supported features and library implementation. Scala 2.13, with its main focus on modularizing standard library and simplifying collections, brings around such a change one more time.This book addresses both technical and architectural changes by providing a comprehensive guide to the redesigned standard library and collections as well as covering in-depth type system and first-level support for functions. It will teach you how to leverage implicits as a primary mechanism for building type classes and looks at different ways to test Scala code. You will learn about abstract building blocks used in functional programming, giving understanding sufficient to pick up and use any existing functional programming library out there.The book will explore reactive programming by covering Akka framework and reactive streams. Finally, 2 definitive projects will help you will build microservices and teach you how to implement them with Scala and Lagom framework.What you will learnAcquaint yourself with the new standard library and collection API of Scala 2.13.Get to grips with the Grok functional paradigms modern Scala libraries are built upon.Get familiar with latest patterns of using type system to express domain constraints.Understand the actor model and how to use different Akka libraries to implement it.Grasp the concept of microservices and how to build them using existing libraries or Lagom framework.Who This Book Is ForThis book is for beginner to intermediate level Scala developers who would like to advance and gain knowledge of the intricacies of the Scala language, expand their functional programming tools, and explore actor-based concurrency models.About the AuthorSlava Schmidt (@slavaschmidt) is a software developer living in Germany.Throughout his career, he has used a wide spectrum of programming languages ranging from Assembler to Haskell and progressed from “Intern Programmer” to “Head of Engineering” to “Scala Contractor”.
