Already 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.
