HTML5 Data and Services Cookbook

Overview of this book

HTML5 is everywhere. From PCs to tablets to smartphones and even TVs, the web is the most ubiquitous application platform and information medium bar. Its becoming a first class citizen in established operating systems such as Microsoft Windows 8 as well as the primary platform of new operating systems such as Google Chrome OS. "HTML5 Data and Services Cookbook" contains over 100 recipes explaining how to utilize modern features and techniques when building websites or web applications. This book will help you to explore the full power of HTML5 - from number rounding to advanced graphics to real-time data binding. "HTML5 Data and Services Cookbook" starts with the display of text and related data. Then you will be guided through graphs and animated visualizations followed by input and input controls. Data serialization, validation and communication with the server as well as modern frameworks with advanced features like automatic data binding and server communication will also be covered in detail.This book covers a fast track into new libraries and features that are part of HTML5!

The HTTP headers are a part of the request object being sent to the server. Many of them give information about the client's user agent setup and configuration, as that is sometimes the basis of making description for the resources being fetched from the server. Several of them such as Etag, Expires, and If-Modified-Since are closely related to caching, while others such as DNT that stands for "Do Not Track" (http://www.w3.org/2011/tracking-protection/drafts/tracking-dnt.html) can be quite controversial. In this recipe, we will take a look at a way for using the custom X-Myapp header in our server and client-side code.

Getting ready

The server will be implemented using Node.js, so you can refer to Appendix A, Installing Node.js and Using npm on how to install Node.js on your machine, and how to use npm. In this example, again for simplicity, we will use restify (http://mcavage.github.io/node-restify/). Also, monitoring the console in your browser and...
