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.
