About This Book

In Detail

The principles of asynchronous event-driven programming are perfect for today's web, where efficient real-time applications and scalability are at the forefront. Server-side JavaScript has been here since the 90's but Node got it right. With a thriving community and interest from Internet giants, it could be the PHP of tomorrow.

"Node Cookbook" shows you how to transfer your JavaScript skills to server side programming. With simple examples and supporting code, "Node Cookbook" talks you through various server side scenarios often saving you time, effort, and trouble by demonstrating best practices and showing you how to avoid security faux pas.

Beginning with making your own web server, the practical recipes in this cookbook are designed to smoothly progress you to making full web applications, command line applications, and Node modules. Node Cookbook takes you through interfacing with various database backends such as MySQL, MongoDB and Redis, working with web sockets, and interfacing with network protocols, such as SMTP. Additionally, there are recipes on correctly performing heavy computations, security implementations, writing, your own Node modules and different ways to take your apps live.

Approach

As part of Packt's cookbook series, this book is packed with practical recipes that will get you working efficiently with Node from the start. Each chapter focuses on a different aspect of working with Node.

Who this book is for

If you have some knowledge of JavaScript and want to build fast, efficient, scalable client-server solutions, then Node Cookbook is for you. Experienced users of Node will improve their skills although even if you have not worked with Node before, these practical recipes will make it easy to get started.
