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. Configure your applications and servers to accommodate the cloud Use Ratpack testing structures on both new and legacy applications Add advanced capabilities, such as component binding, with modules Explore Ratpack’s static content generation and serving mechanisms Provide a guaranteed execution order to asynchronous processing Model data and the data access layer to build high-performance, data-driven applications Work with reactive and functional programming strategies Use distribution techniques that support continuous delivery and other deployment tactics

Start building powerful apps that take advantage of the dynamic scripting capabilities of the Groovy language. This book covers Groovy fundamentals, such as installing Groovy, using Groovy tools, and working with the Groovy Development Kit (GDK). You'll also learn more advanced aspects of Groovy, such as using Groovy design patterns, writing DSLs in Groovy, and taking advantage of Groovy's functional programming features. There is more to Groovy than the core language, so Learning Groovy covers the extended Groovy ecosystem. You'll see how to harness Gradle (Groovy's build system), Grails (Groovy's web application framework), Spock (Groovy's testing framework), and Ratpack (Groovy's reactive web library). What You'll Learn Grasp Groovy fundamentals, including the GDK or Groovy Development Kit Master advanced Groovy, such as writing Groovy DSLs Discover functional programming in Groovy Work with GPars, the built-in concurrency library Use Gradle, the build system Master Grails, the web application framework Work with Spock, the testing framework Harness Ratpack, the reactive web library Who This Book Is For Although this book is intended for those with a Java background, anyone with basic programming skills could benefit from it. This book is a data-filled, yet easy-to-digest tour of the Groovy language and ecosystem.

Using domain-driven design (DDD), software professionals can learn faster, refine their designs more effectively, and build far more successful software systems. However, DDD is widely misunderstood, and it can be intimidating. In Domain-Driven Design Distilled, leading software architect Vaughn Vernon offers a concise and accessible introduction to the DDD paradigm, demystifying all the ideas and techniques you need to explore and adopt it. Vernon shows why it's important to engage with both developers and domain experts as you begin to develop your model's Ubiquitous Language, and how both groups can collaborate far more effectively. You'll learn how to segregate domain models using the powerful "Bounded Contexts" design pattern, and how to develop a Ubiquitous Language as the domain model within an explicitly bounded context. Moving more deeply into strategic design, Vernon shows how Subdomains can help you deal with legacy systems far more effectively. Finally, he demonstrates the use of Context Mapping to integrate multiple Bounded Contexts, and to define both team relationships and technical mechanisms. Domain-Driven Design Distilled brings DDD to life, so you can fully understand it -- and derive maximum value from it.

Imagine what a large-scale web project would look like if frontend development were not treated as an add-on, but as an equal partner with backend development and content strategy. This practical book takes experienced web developers through the new discipline of frontend architecture, including the latest tools, standards, and best practices that have elevated frontend web development to an entirely new level. Using real-world examples, case studies, and practical tips and tricks throughout, author Micah Godbolt introduces you to the four pillars of frontend architecture. He also provides compelling arguments for developers who want to embrace the mantle of frontend architect and fight to make it a first-class citizen in their next project. The four pillars include: Code: how to approach the HTML, CSS, and JavaScript of a design system Process: tools and processes for creating an efficient and error-proof workflow Testing: creating a stable foundation on which to build your site Documentation: tools for writing documentation while the work is in progress
