Introduction v
What This Book is Not
This book is not an introduction to Node.js, nor is it a book that covers all aspects of building a
modern day web application, e.g., websockets, databases, and (of course) front-end development.
Also keep in mind that readers won’t find Express.js Guide aids for learning programming and/or
JavaScript fundamentals here. This is not a beginners’ book.
For an introduction to Node.js, MongoDB, and front-end development with Backbone.js, you might
want to take a look at Azat’s book Rapid Prototyping with JS: Agile JavaScript Development¹⁰.
In the real world, and especially in Node.js development, due to its modularized philosophy, we
seldom use just a single framework. In this book, we have tried to stick to Express.js and leave
everything else out as much as possible, without compromising the usefulness of the examples.
Therefore, we intentionally left out some important chunks of web development — for example
databases, authentication and testing. Although these elements are present in tutorials and examples,
they’re not explained in detail. For those materials, you could take a look at the books in the Related
Reading and Resources section at the end of this book.
Who This Book is For
This book is for people fluent in programming and front-end JavaScript. To get the most benefits,
readers must be familiar with basic Node.js concepts like process and global, and know core
modules, including stream, cluster, and buffer.
If you’re thinking about starting a Node.js project, or about rewriting an existing one, and your
weapon of choice is Express.js — this guide is for you! It will answer most of your “how” and “why”
questions.
Notation
The code blocks will look like this: console.log('Hello reader!');. The terminal and console
commands will have the corresponding prefixes $ and >.
If we mention and use a specific file or a folder, those names will be monospaced as well: index.js.
If there is a class or a module name in the text, it will be in bold type, e.g., superagent.
The new resources will only be hot-linked the first time we mention them.
