The Expert Guide to Building Merb Applications

Thousands of Ruby and Rails developers are discovering the extraordinary scalability, agility, flexibility, and performance offered by the new Merb MVC framework. The Merb Way is the first comprehensive guide to using, extending, and deploying Merb. Like the bestseller The Rails Way (Addison-Wesley, 2008), this book can either be read cover-to-cover as a tutorial or used for modular coverage that makes it an ideal task reference. Foy Savas systematically covers everything developers need to know to build production-quality Merb applications, offering detailed code examples for jumpstarting virtually any project.

Savas is not only involved in the Merb project as an open source contributor: He uses Merb every day as a professional developer. Drawing on his extensive practical expertise, he delves deeply into the Merb framework’s architecture and source code, revealing its elegance and offering powerful best practices for using it. To maximize this book’s practical value, he also covers the tools most widely used alongside Merb, including the DataMapper ORM, the RSpec tester (and associated behavior-driven development techniques), and several leading Merb plugins.
