Node Cookbook

Overview of this book

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.

Connecting and sending SQL to a MySQL server

Structured Query Language has been a standard since 1986 and it's the prevailing language for relational databases. MySQL is the most popular SQL relational database server around, often appearing in the prevalent LAMP (Linux Apache MySQL PHP) stack.

If a relational database was conceptually relevant to our goals in a new project, or we were migrating a MySQL-backed project from another framework to Node, the third-party mysql module would be particularly useful.

In this task, we will discover how to connect to a MySQL server with Node and execute SQL queries across the wire.

Getting ready

Let's grab mysql, which is a pure JavaScript (as opposed to C++ bound) MySQL client module.

npm install mysql

We'll need a MySQL server to connect to. By default, the mysql client module connects to localhost, so we'll have MySQL running locally.

On Linux and Mac OSX we can see if MySQL is already installed with the following command:

whereis mysql

And we can see...
