Preface

Introduction

Node.js is quickly becoming one of the most influential technologies in the Web development community. This book aims to give programmers the information they need to effectively learn how to get started with Node.

This book expects you to have some understanding of JavaScript and programming in general, but we take the time to introduce you to the concepts that are important in event-driven programming on the server, rather than just focusing on the APIs that Node provides.

By reading this book you'll learn not just about Node, the platform, but also about some of the most important modules for Node that will let you quickly and effectively build highly scalable websites and services.
