Learning Ratpack: Simple, Lean, and Powerful Web Applications (Paperback) (ISBN-13: 9781491921661)

Build robust, highly scalable reactive web applications with Ratpack, the lightweight JVM framework. With this practical guide, you'll discover how asynchronous applications differ from more traditional thread-per-request systems--and how you can reap the benefits of complex non-blocking through an API that makes the effort easy to understand and adopt.

Author Dan Woods--a member of the Ratpack core team--provides a progressively in-depth tour of Ratpack and its capabilities, from basic concepts to tools and strategies to help you construct fast, test-driven applications in a semantic and expressive way. Ideal for Java web developers familiar with Grails or Spring, this book is applicable to all versions of Ratpack 1.x.
