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.

Preface

Storing data to CouchDB with Cradle


In order to achieve stellar performance speeds, MongoDB has a relaxed view towards ACID (Atomicity Consistency Isolation Durability) compliance. However, this means there is an (unlikely) chance that data can become corrupted (especially if there was a power cut in the middle of an operation). CouchDB, on the other hand, is ACID compliant to the extent that, when replicated and synchronized, data eventually becomes consistent. Therefore, while slower than MongoDB, it has the added reliability advantage.

CouchDB is entirely administrated via HTTP REST calls, so we could do all of our work with CouchDB using http.request. Nevertheless, we can use Cradle to interact with CouchDB in an easy, high-level way, along with the added speed enhancement of automated caching.

In this recipe, we'll use Cradle to store famous quotes to CouchDB.

Getting ready

We'll need to install and run CouchDB, we can head on to http://wiki.apache.org/couchdb/Installation for instructions...
