RRPS03 | Design Patterns in JavaScript

This repository contains examples of various design patterns implemented in JavaScript. Each design pattern is organized into multiple files for better structure and modularity.

Adapter Pattern

The Adapter pattern allows objects with incompatible interfaces to work together. It acts as a bridge between two incompatible interfaces, making them compatible.

Files

• index.js: Usage example of the Adapter pattern.
• legacyPaymentGateway.js: represents a legacy payment gateway with an incompatible interface.
• legacyPaymentGatewayAdapter.js: is the adapter that adapts the legacy payment gateway to the interface expected by the paymentProcessor.
• paymentProcessor.js: represents the client code that interacts with the payment gateway through the adapter.

Builder Pattern

The Builder pattern separates the construction of an object from its representation, allowing the same construction process to create different representations.

Files

• houseBuilder.js: Represents a house builder that constructs the house object step by step.
• house.js: Represents the house object.
• index.js: Usage example of the Builder pattern.

Prototype Pattern

The Prototype pattern allows objects to be copied or cloned without exposing their underlying implementation details. It provides a mechanism for creating new objects by duplicating existing ones.

Files

• sheep.js: Represents a sheep object with cloning functionality.
• index.js: Usage example of the Prototype pattern.

Decorator Pattern

The Decorator pattern dynamically adds additional behaviors or features to an object without modifying its underlying structure. It provides a flexible alternative to subclassing for extending the functionality of an object.

Files

• pizza.js: Represents the component interface for pizzas.
• margheritaPizza.js: Represents a concrete component, Margherita Pizza.
• pizzaDecorator.js: Represents the base decorator class.
• extraCheeseDecorator.js: Represents a concrete decorator, Extra Cheese Decorator.
• mushroomDecorator.js: Represents a concrete decorator, Mushroom Decorator.
• index.js: Usage example of the Decorator pattern.

Bridge Pattern

The Bridge pattern decouples an abstraction from its implementation, allowing both to vary independently. It provides a way to separate the interface from the implementation and allows them to evolve independently.

Files

• shapes.js: Represents the abstraction in the Bridge pattern, including Circle and Square.
• colors.js: Represents the implementor in the Bridge pattern, including Red, Blue, and Green colors.
• index.js: Usage example of the Bridge pattern.
