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.

Browser-server transmission via AJAX

We can enhance the user experience by loading new content directly into the page via AJAX, rather than loading a new page for each content request.

In this recipe, we're going to transfer our serialized data to the browser as the user requests it and then interact with our client-side data. We'll implement a profile viewer in the browser, which retrieves a selected profile in either JSON or XML, outputting the key-values or parent-child nodes for that profile.

Getting ready

We're going to continue to work with our profiles.js object module (from the first two recipes of this chapter). For XML delivery, we'll also grab our buildXml function from the Converting an object to XML and back again recipe, converting it to a simple module (just like we did with our profiles object in the previous recipe):

module.exports = function buildXml(rootObj, rootName) {
//..buildXml function code

We'll save this as buildXml.js and place it in a folder with a copy of our...
