Foreword

No matter how powerful your web framework, or how well-documented it may be, and independent of all of those tutorials, tips, and blog posts you find on the web, there is no replacement for a book that thoroughly introduces you to the topic. For many years Grails in Action has been the guide for the growing number of Grails developers.

Whenever I visit a team that uses Grails I look around to see what books they have available, and I’m always delighted to see Grails in Action, since I can rely on the solid foundation they got from the book, and I can easily refer to it for best practices and background knowledge.

But the world is ever-changing and the Groovy and Grails worlds particularly so. Web technologies rise and fall quickly these days and Grails adapts mostly through its immense plugin community, but also by carefully evolving the framework itself.

All these changes called for a second edition of our beloved Grails book, and I am so glad to finally have it in my hands!

Glen and Peter have managed to bring in all the new while retaining the characteristics of the first edition: it’s very approachable for the beginner, short and clear for the impatient, covers all bases for the practitioner, and drives the ball deep for the expert—all this with their special touch of humor for an enjoyable read.

Have fun using Grails in action with Grails in Action, Second Edition!
