Our Ruby on Rails starter pack is aimed at those who’ve been interested in this popular web application framework but have never gotten around to trying it out because they didn’t know where to start. Compared to traditional Ruby on Rails tutorials, this starter pack doesn’t hold your hand, teaching you the basics step by step. Instead, it serves as a general introduction to Ruby on Rails and as a signpost with the directions to some of the most useful Ruby on Rails resources on the web. By the time you finish it, you’ll know exactly which steps to take to go from a Ruby on Rails newbie to pro.
What is Ruby on Rails?
According to Wikipedia, Ruby on Rails, often just called Rails, is a server-side web application framework written in Ruby under the MIT License. The framework was created by David Heinemeier Hansson, a partner at the web-based software development firm Basecamp.
Ruby on Rails played a significant role in helping Basecamp shift from web design to web application development. Hansson and others at the company found existing programming languages, such as PHP and Java, unfit for their needs, deciding to, instead, create a new web application framework, initially only for internal use. They finally decided to publicly release Ruby on Rails in 2004, and the rest is history.
Instead of introducing exotic new ideas, Rails is founded on pragmatism and established conventions for easier collaboration and maintenance. “You could develop a web application at least ten times faster with Rails than you could with a typical Java framework”, believes Paul Piwowarski of the University of Kentucky.
Some of the more noteworthy characteristics of Rails include:
- Omakase: It’s often said that Rails is omakase. This Japanese phrase means “I’ll leave it to you”, and it’s often used by customers at sushi restaurants who want the chef to make a selection for them. Hansson famously said, “A team of chefs picked out the ingredients, designed the APIs, and arranged the order of consumption on your behalf according to their idea of what would make for a tasty full-stack framework. The menu can be both personal and quirky. It isn’t designed to appeal to the taste of everyone, everywhere”.
- Opinionated software: The term “opinionated software” is used to expressed the same idea as the phrase “omakase”. Simply put, it means that Rails works best when the developer sticks to the beaten path, instead of trying to do things differently. Not that they can’t be done differently–they can–but it’s almost always quicker and better to do things the Rails way.
- Convention over configuration: Rails makes many assumptions based on convention. Rails developers are deeply familiar with these conventions (like when a developer knows that a model object named “User” will automatically save data to a database table named “users”), and they rely on them to save time and avoid mistakes.
- Don’t repeat yourself: Formulated by Andy Hunt and Dave Thomas, this software development principle preaches the avoidance of duplication—not only code duplication but also process duplication. Rails embraces automatic testing as well as software design patterns that introduce abstraction and indirection.
When looked at from the bird’s eye view, it becomes apparent that Rails is more than a software library. Rails sits at the center of a vast ecosystem of building blocks used by web developers to rapidly build complex web projects. This ecosystem is based on volunteerism, enthusiasm, and love for the web.
Ruby vs Ruby on Rails
The Ruby programming language was developed by Yukihiro Matsumoto, better known as Matz, and released in 1995 on Japanese domestic newsgroups. The language now ranks among the top ten most popular programming languages, not in small part also thanks to Ruby on Rails.
Ruby is a general-purpose, high-level programming language that combines Smalltalk’s conceptual elegance with Python’s ease of use and Perl’s pragmatism. “As a language-maniac and OO fan for 15 years, I really wanted a genuine object-oriented, easy-to-use scripting language. I looked for it but couldn’t find one. So, I decided to make it”, said Yukihiro Matsumoto.
Ruby on Rails is a server-side, model–view–controller Ruby framework for web application development. It adds extra code to Ruby to simplify the development of complex web projects.
Do You Need to Study Ruby to Learn Rails?
If you’re reading our starter pack because you want to learn Rails as quickly as possible, you may find the idea of having to learn another programming language just to become proficient at Rails discouraging, and we wouldn’t blame you for feeling that way. The good news is that you don’t need to learn Ruby if you don’t want to. That said, even a basic grasp of Ruby can make learning Rails much easier, especially in the beginning. What’s more, as you learn Rails, you’ll also naturally develop Ruby skills, so it’s not like there are thousands of Rails pros without a clue how to create a hello world program in Ruby.
Ruby on Rails vs PHP
According to the official website, “PHP is an open source general-purpose scripting language that is especially suited for web development and can be embedded into HTML”. PHP was created by Rasmus Lerdorf, a Danish-Canadian programmer, and first released in 1995. The three-letter name originally stood for Personal Home Page, but it’s now a recursive initialism for PHP: Hypertext Preprocessor.
One fascinating thing about PHP is the fact that the language was developed without a written formal specification until 2014, in stark contrast to Ruby on Rails, which is heavily standardized, emphasizing the convention over configuration principle.
PHP is generally considered to be easier than Ruby and Ruby on Rails, and it also has a larger user base as well as more learning resources. On the other hand, the automated approach to software development embraced by Rails leads to faster deployment speeds and greater development joy.
What Is Ruby on Rails Used for?
Today, Ruby on Rails is one of the most popular frameworks for building complex, scalable web applications. In GitHub’s Octoverse 2016, Ruby ranked as the fourth most popular language used on GitHub, with Python stealing its place among the top three most popular languages by a very small margin.
Ruby on Rails is widely popular in Silicon Valley, adopted by some of the most successful startups that have emerged during the pay several years. The large collection of third-party libraries and focus on test automation means that both startups and everybody else can create powerful applications and deliver more features in less time.
Some of the most prominent startups that are using Ruby on Rails include Airbnb, Basecamp, GitHub, Twitch, and Kickstarter, just to name a few.

Let’s face it: who wouldn’t want to be a Rails ninja? Just imagine how a title like that would look on your resume, and how many free drinks it would get you at the club. Well, the second part might be a bit far-fetched. The truth is, though, that with Glenn Goodrich’s book, you can become an actual Ruby on Rails ninja! The book takes an easy-to-follow approach that keeps the material progressing at a breezy pace. Goodrich requires readers to understand HTML and some CSS, but that shouldn’t be an obstacle for most people who want to learn Rails.
Practical Object-Oriented Design in Ruby by Sandi Metz
This well-written book by Sandi Metz addresses one of Ruby’s biggest downsides: long-term maintainability. In Practical Object-Oriented Design in Ruby, Metz explores how well executed object-oriented design can lead to better applications and lower development costs. Admittedly, intermediate and advanced Ruby on Rails developers can learn the most from a book of this caliber, but even relative beginners can benefit from reading certain chapters.
Essential Ruby on Rails Tools
Ruby Version Manager (RVM) is a command-line tool maintained by a community of volunteers, allowing developers to install, manage, and work with multiple Ruby environments. It’s possible to install RVM on most UNIX-like systems and Windows. RVM Windows requires either Cygwin or the Windows Subsystem for Linux, which is available from the Windows Store. For many years, RVM was the only way to manage multiple versions of Ruby on a single development machine. But even though we now have many other similar tools, RVM has retained much of its relevance to this day.
RubyInstaller for Windows
RubyInstaller for Windows is a self-contained installer for the Windows operating system that includes the Ruby language, an execution environment, documentations, and other useful things. Installing RubyInstaller for Windows is easy: select which version you would like to install from the official download page, download the installer, and follow a series of simple steps to install the software on your computer. If you decide to go with the latest Ruby version, you may discover some stability issues, which is why the developers of RubyInstaller for Windows recommend downloading an older version.
All developers can benefit from excellent Ruby version managers. Homebrew is widely considered to be the best package manager for the macOS operating system because it makes very complicated tasks simple. It automatically resolves dependencies, aids with source code configuration, takes care of compilation, and manages updates.
In this day and age, software security is not to be taken lightly. Malicious hackers release new, devastating strains of malware into the wild every day, and large-scale, targeted attacks are making the headlines on a regular basis. Brakeman is an automatic vulnerability scanner for Ruby on Rails applications. It applies statistical analysis on application source code to discover security issues and programming errors. Brakeman is also available as a commercial software with a convenient graphical user interface.
Sublime Text is a splendid, snappy text editor with a sleek user interface, support for plugins, a ton of useful features, and an excellent community behind it. With Sublime Text, you can search across multiple documents at once, get the most out of your desktop or laptop monitor with split editing support, write without distracting menu bars, and customize just about every aspect of the editor to your heart’s content. Ruby and Ruby on Rails are, of course, fully supported, and many developers have detailed their experience with using Sublime Text for Rails development.
We’ve placed Disk Drill at the end of this section because its use extends far beyond Rails development. Disk Drill is a premium data recovery suite for Windows and macOS computers. When working on an important project, the last thing you want is to lose days or weeks or even months of hard work due to a catastrophic hard drive failure or an astronomical user error.
Disk Drill can recover over 200 file formats, including the source files of your Rails projects. Data recovery with Disk Drill is easy, yet the software features highly sophisticated data recovery algorithms capable of handling even the most challenging data recovery scenarios.
