DESCRIPTION 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.js in Action is a carefully designed tutorial that teaches 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.
