5. The Type Astronaut’s Guide to Shapeless Book by Dave Gurnell

The Type Astronaut’s Guide to Shapeless Book

The book is divided into two parts. Part I introduces the general mechanisms for type class derivation in shapeless. It introduces generic encodings of product and coproduct types (case classes and sealed traits), and shows how to implement type classes by solving problems at the generic level.

Part II opens the shapeless toolbox and show how to apply the solutions from Part I to a wider range of situations. The author introduces polymorphic functions that let us map and flatMap over generic representations, and show how we can count at the type level.

6. Scala with Cats by Noel Welsh and Dave Gurnell

Scala with CatsThe main goal of this book is to teach system architecture and design using the techniques of modern functional programming. This means designing systems as small composable units, expressing constraints and interactions via the type system, and using composition to guide the construction of large systems in a way that maintains the original architectural vision.

The book also serves as an introduction to the Cats library. The authors use abstractions from Cats, and explain the structure of Cats so you can use it without fear in your own code base. The broad ideas are not specific to Cats, but Cats provides an excellent implementation that is beneficial to learn in its own right.

7. Functional Programming for Mortals with Scalaz by Sam Halliday

Functional Programming for MortalsFunctional Programming for Mortals with Scalaz bills itself as a comprehensive and practical introduction to Functional Programming for Scala developers.

This book is for the typical Scala developer, probably with a Java background, who is both skeptical and curious about the Functional Programming (FP) paradigm.

This book justifies every concept with practical examples, including writing a web application.

8. Pro Scala: Monadic Design Patterns for the Web by L.G. Meredith

Pro Scala: Monadic Design Patterns for the WebAlready know some Scala, but want to take the next step and make practical use of modern monadic design patterns? This is the book for you.

This book addresses advanced programming techniques in Scala from the point of view of design patterns for web development. These patterns are discussed across the whole of the processing pipeline, from HTTP requests to storage and back again.

Major emphasis is placed on key abstractions from functional programming that are often considered out of the purview of the professional programmer, but that are of key practical importance.
