CoffeeScript in Action
JavaScript runs (almost) everywhere but it can be quirky and awkward. Its cousin CoffeeScript is easier to comprehend and compose. An expressive language, not unlike Ruby or Python, it compiles into standard JavaScript without modification and is a great choice for complex web applications. It runs in any JavaScript-enabled environment and is easy to use with Node.js and Rails. CoffeeScript in Action teaches you how, where, and why to use CoffeeScript. It immerses you in CoffeeScript's comfortable syntax before diving into the concepts and techniques you need in order to write elegant CoffeeScript programs. Throughout, you'll explore programming challenges that illustrate CoffeeScript's unique advantages. For language junkies, the book explains how CoffeeScript brings idioms from other languages into JavaScript. ...

Component-Based Rails Applications
As Rails applications grow, even experienced developers find it difficult to navigate code bases, implement new features, and keep tests fast. Components are the solution, and Component-Based Rails Applications shows how to make the most of them. Writing for programmers and software team leads who are comfortable with Ruby and Rails, Stephan Hagemann introduces a practical, start-to-finish methodology for modernizing and restructuring existing Rails applications. One step at a time, Hagemann demonstrates how to revamp Rails applications to exhibit visible, provably independent, and explicitly connected parts - thereby simplifying them and making them far easier for teams to manage, change, and test. Throughout, he introduces design concepts and techniques you can use to improve applications of many kinds, even if they weren't built with Rails or Ruby. Learn how components clarify intent, improve collaboration, and simplify innovation and maintenance; Create a full Rails applic ...

Programming Elixir 1.6
Functional programming techniques help you manage the complexities of today's real-world, concurrent systems; maximize uptime; and manage security. Enter Elixir, with its modern, Ruby-like, extendable syntax, compile and runtime evaluation, hygienic macro system, and more. But, just as importantly, Elixir brings a sense of enjoyment to parallel, functional programming. Your applications become fun to work with, and the language encourages you to experiment. Part 1 covers the basics of writing sequential Elixir programs. We'll look at the language, the tools, and the conventions. Part 2 uses these skills to start writing concurrent code—applications that use all the cores on your machine, or all the machines on your network! And we do it both with and without OTP. Part 3 looks at the more advanced features of the language, from DSLs and code generation to extending the syntax. This edition is fully updated with all the new features of Elixir 1.6, with a new chapter on structurin ...

Practical Object-Oriented Design, 2nd Edition
Object-oriented programming languages exist to help you create beautiful, straightforward applications that are easy to change and simple to extend. Unfortunately, the world is awash with object-oriented (OO) applications that are difficult to understand and expensive to change. Practical Object-Oriented Design, Second Edition, immerses you in an OO mindset and teaches you powerful, real-world, object-oriented design techniques with simple and practical examples. Sandi Metz demonstrates how to build new applications that can "survive success" and repair existing applications that have become impossible to change.
