About this Book
Welcome to Express in Action! This book aims to teach you everything about Express.js, the web framework that makes the powerful Node.js easy to use.
This book assumes you have intermediate JavaScript knowledge. This includes things like anonymous functions, closures, and callbacks.
This book is divided into three parts.
Part 1 is an introduction to Express and the shoulders it stands on. You might wonder: what is Express? What is its relationship to Node.js (and what is Node.js)? What can Express do? What can’t it do? All of these questions (and more) will be answered in the first three chapters. Part 1 aims to give you a strong conceptual understanding of the framework.
