Node.js is white hot, powering the server side of major web apps from Walmart, PayPal, and Netflix. While super-powerful, raw Node can be complex and awkward. Express.js is a web application framework for Node that organizes server-side JavaScript into testable, maintainable modules. It provides a powerful set of features to efficiently manage routes, requests, and views, along with beautiful boilerplate for web applications. Lightweight, fast, and unobtrusive, Express helps harness Node's raw power so developers can concentrate on what the application does instead of managing the nit-picky technical details. Express in Action is a carefully designed tutorial that teaches developers how to build web applications using Node and Express. It starts by introducing Node's unique characteristics and then shows how they map to the features of Express. With a clear vision of how an Express application looks, readers can systematically explore key development techniques, meet the rich ecosystem of companion tools and libraries, and even get a glimpse into its inner workings. After just a few chapters, they'll be able to build a simple Node app. By the end of the book, they'll know how to test it, hook it up to a database, and even automate the dev process. Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications.

Express.js in Action

Developers looking to keep their JavaScript code bug-free will want to unit test using Jasmine, one of the most popular unit testing frameworks around. Any project of meaningful size should be automatically tested to help catch bugs as early as possible. Jasmine, a testing framework for JavaScript, makes it easy to test JavaScript projects, from browser-based applications to Node.js. While a quick understanding of Jasmine can be gleaned from the project’s homepage, the framework has a lot of details and exciting plugins. This book explores Jasmine in a depth that can’t be found elsewhere. This book provides: Exposure to some Jasmine plugins, to extend Jasmine and allow for more functionality and more thorough testing An Understanding of Jasmine’s main features, to allow code to be automatically tested and reduce bugs An Explanation of how to get Jasmine working in different environments (in the browser, in Node.js, through Rails, et cetera), to make Jasmine easier to work with

JavaScript Testing with Jasmine

Get a concise introduction to Jasmine, the popular behavior-driven testing framework for JavaScript. This practical guide shows you how to write unit tests with Jasmine that automatically check for bugs in your application. If you have JavaScript experience—with knowledge of some advanced features—you’ll learn how to write specifications for individual components, and then use those specs to test the code you write. Throughout the book, author Evan Hahn focuses primarily on methods for testing browser-based JavaScript applications, but you’ll also discover how to use Jasmine with CoffeeScript, Node.js, Ruby on Rails, and Ruby without Rails. You won’t find a more in-depth source for Jasmine anywhere. Get an overview of both test-driven and behavior-driven development Write useful specs by determining what you need to test—and what you don’t Test the behavior of new and existing code against the specs you create Apply Jasmine matchers and discover how to build your own Organize code suites into groups and subgroups as your code becomes more complex Use a Jasmine spy in place of a function or an object—and learn why it’s valuable
