RSpec Essentials
This book will teach you how to use RSpec to write high-value tests for real-world code. We start with the key concepts of the unit and testability, followed by hands-on exploration of key features. From the beginning, we learn how to integrate tests into the overall development process to help create high-quality code, avoiding the dangers of testing for its own sake. We build up sample applications and their corresponding tests step by step, from simple beginnings to more sophisticated versions that include databases and external web services. We devote three chapters to web applications with rich JavaScript user interfaces, building one from the ground up using behavior-driven development (BDD) and test-driven development (TDD). The code examples are detailed enough to be realistic while simple enough to be easily understood. Testing concepts, development methodologies, and engineering tradeoffs are discussed in detail as they arise. This approach is designed to foster the rea ...

Sails.js Essentials
Sails.js makes it easy to build custom, enterprise-grade Node.js apps. It is designed to emulate the familiar MVC pattern of frameworks, but with support for the requirements of modern apps: data-driven APIs with a scalable, service-oriented architecture. This book will provide practical examples to get you started with Sails.js and get you develop production-ready apps in no time. We will take you from a Node.js web server and single threading system to a general MVC architecture. You will then learn to develop applications that you might be already familiar with using Sails.js. Finally, we will show you how to create a chat app and a to-do application, and improve code quality using JSHINT and JSCS. ...

Seven Mobile Apps in Seven Weeks
Understanding the idioms, patterns, and quirks of the modern mobile platforms gives you the power to choose how you develop. Over seven weeks you'll build seven different mobile apps using seven different tools. You'll start out with Mobile Web; develop native apps on iOS, Android, and Windows; and finish by building apps for multiple operating systems using the native cross-platform solutions RubyMotion, React Native, and Xamarin. For each platform, you'll build simple, but non-trivial, apps that consume JSON data, run on multiple screen sizes, or store local data. You'll see how to test, how to build views, and how to structure code. You'll find out how much code it's possible to share, how much of the underlying platform you still need to know, and ultimately, you'll get a firm understanding of how to build apps on whichever devices your users prefer. This book gives you enough first-hand experience to weigh the trade-offs when building mobile apps. You'll compare writing apps on ...

Learn Functional Programming with Elixir
Functional programming offers useful techniques for building maintainable and scalable software that solves today's difficult problems. The demand for software written in this way is increasing - you don't want to miss out. In this book, you'll not only learn Elixir and its features, you'll also learn the mindset required to program functionally. Elixir's clean syntax is excellent for exploring the critical skills of using functions and concurrency. Start with the basic techniques of the functional way: working with immutable data, transforming data in discrete steps, and avoiding side effects. Next, take a deep look at values, expressions, functions, and modules. Then extend your programming with pattern matching and flow control with case, if, cond, and functions. Use recursive functions to create iterations. Work with data types such as lists, tuples, and maps. Improve code reusability and readability with Elixir's most common high-order functions. Explore how to use lazy computa ...

Typed PHP
Discover how stronger types mean cleaner, more efficient, and optimized PHP applications. This unique book looks at typed PHP: PHP types, strings, regular expressions, and more from PHP 7 as found in standard PHP libraries, user libraries, extensions, and cross-compilers. You'll see how to create a set of reusable tools that unify and ease the scalar types of PHP. PHP has a rich history and a dominant place on the web. It has achieved much despite language inconsistencies and difficulties. Bjarne Stroustrup once said: "There are only two kinds of languages: the ones people complain about and the ones nobody uses". PHP is one of those languages that everybody uses, yet that's often seen as a good reason to ignore the bad parts and just get stuff done. We're all for getting stuff done, and to that end, the author has used Plain Ol' PHP for many years. It's always bugged him how procedural PHP is, in an ecosystem of OOP libraries and frameworks. So he decided to take a dee ...
