Coding Style for This Book

One of the reasons Node.js and CouchDB were selected for this book is that, from the

beginning, these products are HTTP-aware. That means the software works well using

the existing HTTP application protocol and in a state-less environment like the World

Wide Web. As a result, there is very little friction between the components I created

using Node and CouchDB, and the protocol used to communicate with those compo-

nents.

It is also an advantage that these software systems all use the same front-facing pro-

gramming language for scripting (Javascript). While not all readers will be proficient

in Javascript, hopefully this single language format can reduce the need for mental

context-switching when moving between client code, server code, and data storage

implementation.

The important point, though, is that the software is not the focus for this book; it is

merely the medium for the hypermedia message. You will likely find that many of the

examples contain code that is either too brief or too fragile to run in a production

environment. This is mostly a matter of expediency; I’m anxious to illustrate the details

of the hypermedia, not the code used to implement that design. These designs will work

well when implemented for any platform, using any language, running on any operating

system. I suspect many readers will find better ways to implement these media type

designs using their own languages and platforms, and that’s all the better.

The following typographical conventions are used in this book:

Italic

Indicates new terms, URLs, email addresses, filenames, and file extensions.

Constant width

Used for program listings, as well as within paragraphs to refer to program elements

such as variable or function names, databases, data types, environment variables,

statements, and keywords.

Constant width bold

Shows commands or other text that should be typed literally by the user.

Constant width italic

Shows text that should be replaced with user-supplied values or by values deter-

mined by context.

Using Code Examples

This book is here to help you get your job done. In general, you may use the code in

this book in your programs and documentation. You do not need to contact us for

permission unless you’re reproducing a significant portion of the code. For example,

writing a program that uses several chunks of code from this book does not require

permission. Selling or distributing a CD-ROM of examples from O’Reilly books does

require permission. Answering a question by citing this book and quoting example

code does not require permission. Incorporating a significant amount of example code

from this book into your product’s documentation does require permission.

We appreciate, but do not require, attribution. An attribution usually includes the title,

author, publisher, and ISBN. For example: “Building Hypermedia APIs with HTML5

978-1-449-30657-1.”

If you feel your use of code examples falls outside fair use or the permission given above,

Acknowledgements

There are quite a number of people who deserve acknowledgement for the completion

of this book.

Several people volunteered to review early drafts of this book and provided excellent

feedback and suggestions. Thanks to Leonard Richardson, Erik Wilde, Ian Robinson,

Jan Algermissen, Mike Kelly, Will Hartung, William Martinez Pomares, Erlend Ham-

naberg, Darrel Miller, Glenn Block, David Zulke, Erik Morgensen, Kevin Burns Jr.,

Jonathan Moore, and Subbu Allamaraju. If the book is accurate, clear, and concise,

that is likely due to the contributions of these individuals. Any remaining shortcomings

are solely the responsibility of the author.

Julian Reschke, Mykyta Yevstifeyev, Frank Ellermann, and others were very helpful

and generous as I worked to learn the details of IETF and IANA procedures and pro-

cesses.

I’d like to thank Benjamin Young for introducing me to CouchDB and for all his efforts

to teach me how to improve my understanding and coding of CouchDB. His willingness

to spend one-on-one time to help me get past some hurdles was invaluable. If there are

shortcomings or errors in the CouchDB code, it’s most likely because I failed to grasp

what Benjamin tried to teach me; my apologies to the reader and to Benjamin Young.

Simon St. Laurent, my editor, has been a great champion of this book. Without his

tireless efforts, this book would never have seen the light of day. Thanks also to Melanie

Yarbrough for all her proofreading and editing work.
