RESTful Web Clients
Web-based REST and Hypermedia services are becoming more common every day, but very few client libraries take advantage of these powerful API features—mostly because the techniques and patterns needed to create successful hypermedia clients have been ignored. Yet, when done right, hypermedia-based client applications exhibit more stability and flexibility than typical one-off custom client code. This practical book takes you on a journey from custom bespoke implementations to powerful general-purpose client applications and, along the way, shows how you can harness many of the basic principles that underpin the Web. Throughout the book, you'll find practical, approachable examples and dialogs, as well as clear guidance on how to understand this increasingly important conversation. ...

Rails 5 Test Prescriptions
Your Ruby on Rails application is sick. Deadlines are looming, but every time you make the slightest change to the code, something else breaks. Nobody remembers what that tricky piece of code was supposed to do, and nobody can tell what it actually does. Plus, it has bugs. You need test-driven development: a process for improving the design, maintainability, and long-term viability of software. With both practical code examples and discussion of why testing works, this book starts with the most basic features delivered as part of core Ruby on Rails. Once you've integrated those features into your coding practice, work with popular third-party testing tools such as RSpec, Jasmine, Cucumber, and factory_bot. Test the component parts of a Rails application, including the back-end model logic and the front-end display logic. With Rails examples, use testing to enable your code to respond better to future change. Plus, see how to handle real-world testing situations. This new edition ...

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 ...
