Dynamic typing
Ruby is dynamically typed, allowing developers to write code without explicitly declaring variable types. This flexibility enables rapid development and reduces the amount of boilerplate code required. While dynamic typing can introduce potential runtime errors, Ruby’s powerful error handling mechanisms and testing frameworks help mitigate these risks.
Metaprogramming capabilities
One of the standout features of Ruby is its metaprogramming capabilities. Metaprogramming allows developers to write code that generates other code dynamically. This flexibility enables advanced techniques like defining DSLs (Domain-Specific Languages) and creating dynamic frameworks. Metaprogramming in Ruby opens up endless possibilities for creating expressive and efficient web applications.
Ruby frameworks for web development
Ruby on Rails
Ruby on Rails, often referred to as Rails, is the most popular web framework built using Ruby. Rails follows the Model-View-Controller (MVC) architectural pattern and provides a convention-over-configuration approach. This convention-based approach minimizes the time spent on repetitive tasks and encourages best practices. Rails offers a wide range of built-in features, including database integration, routing, and template rendering.
Sinatra
Sinatra is a lightweight web framework that prioritizes simplicity and minimalism. It is an excellent choice for small to medium-sized projects that don’t require the full feature set of Rails.

Building web applications with Ruby
Building web applications with Ruby typically follows the Model-View-Controller (MVC) architectural pattern. The MVC pattern separates the application’s logic into three distinct components: models, views, and controllers.
MVC architecture
Models represent the data and business logic of the application. They handle data storage and retrieval, business rules, and relationships between objects. Models are responsible for encapsulating the core functionality of the application.
Views are responsible for presenting the data to the users. They generate the HTML, CSS, and JavaScript required to render the user interface. Views ensure a clean separation between the presentation layer and the application’s underlying logic.
Controllers act as intermediaries between models and views. They handle user requests, process input data, and update the models accordingly. Controllers coordinate the flow of data between models and views, ensuring that the application responds to user interactions appropriately.
Routing and controllers
In Ruby web applications, routing maps incoming HTTP requests to specific controllers and actions. Routing defines the URLs and HTTP methods that trigger specific functionality within the application. Controllers receive requests, invoke the necessary models and services, and generate responses to be sent back to the users.
Views and templates
Views in Ruby web development typically use template engines to generate dynamic content. Commonly used template engines include ERB (Embedded Ruby), Haml, and Slim. These template engines allow developers to embed Ruby code within HTML or other markup languages, enabling dynamic content generation.
Testing and debugging in Ruby web development
RSpec for unit testing
RSpec is a popular testing framework in the Ruby ecosystem. It follows a behavior-driven development (BDD) approach, allowing developers to describe the expected behavior of their code using descriptive syntax. RSpec provides a clean and expressive way to write tests, making it easier to catch bugs and ensure code quality.
