Overview of this book

The beauty of Ruby is its readability and expressiveness. Ruby hides away a lot of the complexity of programming, allowing you to work quickly and 'do more' with fewer lines of code. This makes it a great programming language for beginners, but learning any new skill can still be a daunting task. If you want to learn to code using Ruby, but don't know where to start, The Ruby Workshop will help you cut through the noise and make sense of this fun, flexible language. You'll start by writing and running simple code snippets and Ruby source code files. After learning about strings, numbers, and booleans, you'll see how to store collections of objects with arrays and hashes. You'll then learn how to control the flow of a Ruby program using boolean logic. The book then delves into OOP and explains inheritance, encapsulation, and polymorphism. Gradually, you'll build your knowledge of advanced concepts by learning how to interact with external APIs, before finally exploring the most popular Ruby framework ? Ruby on Rails ? and using it for web development. Throughout this book, you'll work on a series of realistic projects, including simple games, a voting application, and an online blog. By the end of this Ruby book, you'll have the knowledge, skills and confidence to creatively tackle your own ambitious projects with Ruby.

Introduction

In the previous chapter, we learned about advanced topics in Ruby, such as metaprogramming, how to open existing classes and add new methods to them, and how to monkey patch to create dynamic methods on the fly. We also learned about how to interact with external servers by making RESTful calls to them.

In this chapter, we will learn about Ruby on Rails, also known as Rails or ROR. It is a server-side web application framework distributed as a Ruby gem, written in Ruby and first released in 2005. With Ruby on Rails, we can build real-world web applications quickly. Rails is one of the most popular application frameworks for building web applications quickly. It has best practices of web development built into its architecture to create secure, robust, and scalable web apps. Some popular web applications built using Ruby on Rails are Basecamp, GitHub, Shopify, Airbnb, Twitch, SoundCloud, Hulu, Zendesk, and Square – the list goes on.
