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). Youll also learn more advanced aspects of Groovy, such as using Groovy design patterns, writing DSLs in Groovy, and taking advantage of Groovys functional programming features. There is more to Groovy than the core language, so Learning Groovy covers the extended Groovy ecosystem. Youll see how to harness Gradle (Groovys build system), Grails (Groovys web application framework), Spock (Groovys testing framework), and Ratpack (Groovys reactive web library).
