Syllabus for Johns Hopkins University online degree

Welcome and Setting Up the Development Environment
In this module, we will install software required to develop Ruby on Rails applications. We will also demonstrate the use of a popular Ruby on Rails editor called “Sublime Text”. We will finish the module by familiarizing ourselves with a version control system called “Git” that will be used later in the course to submit assignments, as well as to deploy Ruby on Rails applications to a PaaS (platform as a service) called “Heroku”.

Introduction to Ruby
In this module, we will explore the different areas of the Ruby programming language.

We will start with the basics and continue with more advanced topics, such as arrays and hashes. We will also spend time exploring object oriented programming in Ruby, and finish the module by demonstrating how to perform unit testing.

Introduction to Ruby on Rails
In this module, we will become familiar with core concepts behind Ruby on Rails, such as CoC (Convention Over Configuration) and MVC (Model-View-Controller).

We will then learn about consuming JSON API with HTTParty, a Ruby gem. We will then integrate this ability to consume JSON API to serve as the data layer for our Rails application.

Finally, to conclude this module we will deploy the application to Heroku and write a unit test that will verify the desired functionality.
