Welcome to the Design Patterns Wiki! This guide explores common software design patterns that solve recurring problems in application development. Design patterns are like blueprints for code structure, helping developers create scalable and maintainable systems. Let's dive into the essentials!
📚 What Are Design Patterns?
Design patterns are standardized solutions to common programming challenges. They provide a reusable template for solving problems in specific contexts. Think of them as best practices refined over decades of software engineering.
🔍 Key Benefits
- Reusability: Apply proven solutions across projects
- Maintainability: Simplify code understanding and modification
- Scalability: Enable systems to grow efficiently
- Collaboration: Standardize communication between developers
🧩 Common Design Patterns
Here are the three primary categories of design patterns:
1. Creational Patterns
These focus on object creation mechanisms.
- 📌 Singleton: Ensures a class has only one instance
- 📌 Factory Method: Defines an interface for creating objects
- 📌 Abstract Factory: Provides an interface for creating families of related objects
2. Structural Patterns
These deal with object composition and structure.
- 📌 Adapter: Matches interfaces of incompatible classes
- 📌 Decorator: Adds responsibilities to objects dynamically
- 📌 Composite: Composes objects into tree structures
3. Behavioral Patterns
These define communication between objects.
- 📌 Observer: Enables a subscription model
- 📌 Strategy: Encapsulates an algorithm within a class
- 📌 Command: Encapsulates a request as an object
