Learning Ratpack: Simple, Lean, and Powerful Web Applications (Paperback)

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.
