Cloning Internet Applications with Ruby

By: Chang Sau Sheong

Overview of this book

Most users on the Internet have a few favorite Internet web applications that they use often and cannot do without. These popular applications often provide essential services that we need even while we don’t fully understand its features or how they work. Ruby empowers you to develop your own clones of such applications without much ordeal. Learning how these sites work and describing how they can be implemented enables you to move to the next step of customizing them and enabling your own version of these services.This book shows the reader how to clone some of the Internet's most popular applications in Ruby by first identifying their main features, and then showing example Ruby code to replicate this functionality.While we understand that it connects us to our friends and people we want to meet up with, what is the common feature of a social network that makes it a social network? And how do these features work? This book is the answer to all these questions. It will provide a step-by-step explanation on how the application is designed and coded, and then how it is deployed to the Heroku cloud platform. This book’s main purpose is to break up popular Internet services such as TinyURL, Twitter, Flickr, and Facebook to understand what makes it tick. Then using Ruby, the book describes how a minimal set of features for these sites can be modeled, built, and deployed on the Internet.

Technologies and platforms used

We use a number of technologies in this chapter, mainly revolving around the Ruby programming language and its various libraries. In addition to Ruby and its libraries we also use a few mashups, which are described below. We have described Sinatra, DataMapper, and Haml in the previous chapters so we will not repeat this here. Please refer to Chapter 1, Cloning Internet Applications for the details if you need to refresh your memory.


JSON (JavaScript Object Notation) is a lightweight data-interchange format, often used within a web context. It is meant to be easy for humans to read as well as for machines to parse or create. As the name suggests, it was derived from Javascript for representing simple data structures and hashes. However, JSON itself is not programming language-specific and has many implementations in various languages. It is increasingly becoming the popular alternative to sending and receiving XML.

In this application we will be using the...
