Ruby Modules and Mixins
Ruby, known for its simplicity and efficiency, offers various tools and resources, adding a layer of flexibility to the coding environment. Among these tools are Ruby Modules and Mixins. This article will explore these functionalities in detail while providing real-world examples demonstrating their use cases.

Facade in Ruby is a design pattern that helps simplify complex systems by providing a unified interface to a set of interfaces in a subsystem. In Ruby, the Facade pattern provides a simplified interface to a more complex system. You're in the right place if you're new to Ruby and want to learn more about…
In this article, we'll dive deep into more advanced Ruby programming topics, such as metaprogramming, concurrency, and available programming.
Metaprogramming in Ruby
Metaprogramming is the ability to write code that writes code. Metaprogramming is a powerful technique in Ruby that allows developers to generate and modify code at runtime dynamically. This can be useful in…
Visitor Pattern in Ruby
The visitor pattern in Ruby is a way of separating an algorithm from an object structure on which it operates.
A practical way to think about this is:
You have a bunch of objects (nodes) that need to be processed in some way
You don't want to add a new method to…
Template Method in Ruby
The template method in Ruby is one of the most practical design patterns in object-oriented programming.
The template method allows you to define the steps of an algorithm and then will enable subclasses to provide the implementation for one or more actions.
This is useful when you want to keep the overall algorithm the…
Flyweight Pattern in Ruby
The Flyweight pattern in Ruby is a software design pattern used to minimize memory usage by sharing as much data as possible. It is often used with other data structures, such as hash tables and trees.
The idea behind the flyweight pattern is to store data in a way that minimizes the amount…
Facade Pattern in Ruby
The facade pattern in Ruby and OOP is a standard way to simplify interfaces.
In Ruby, you provide a new API that should look simpler than the real API.
You can use this pattern to rewrite 3rd part API, as a wrapper API, or to build an API in front of your database.
For example:
class…
State Pattern in Ruby
The State Pattern in Ruby is a widely used design pattern that allows an object to change its behavior based on its internal state.
An everyday use case for the state pattern is a simple state machine.
For example, you could use the state pattern to implement a simple text editor with different modes…
Memento Pattern in Ruby
The memento pattern in Ruby is a design pattern that allows you to save an object's state and restore it later.
This can be useful for things like undo/redo or for storing the state of an object so that you can resume from that point if the program crashes.
This article will implement the…
The Prototype Pattern in Ruby
The prototype pattern in Ruby is a creational design pattern used when the type of objects to create is determined by a prototypical instance, which is cloned to produce new things.
This pattern is used to:
Avoid subclasses of an object creator
Avoid the inherent cost of creating a new object…
