Design Patterns
Proven solutions for common software design challenges, curated for scalability and maintainability.
Why Architecture Patterns Matter
Design patterns provide a shared language for developers. Instead of reinventing the wheel, we use battle-tested templates like SOLID principles to build systems that are easy to test, maintain, and extend.
Creational Patterns
Focus on object creation mechanisms that increase flexibility and reuse of existing code.
- Singleton: Ensuring a class has only one instance.
- Factory Method: Creating objects without specifying the exact class.
- Builder: Constructing complex objects step by step.
Structural Patterns
Explaining how to assemble objects and classes into larger structures while keeping them flexible.
- Adapter: Allowing incompatible interfaces to work together.
- Facade: Providing a simplified interface to a library or framework.
- Proxy: Controlling access to an object.
Behavioral Patterns
Concerned with algorithms and the assignment of responsibilities between objects.
- Strategy: Defining a family of algorithms and making them interchangeable.
- Observer: A subscription mechanism to notify multiple objects about events.
- Command: Turning a request into a stand-alone object.
Cloud Patterns
Patterns essential for modern cloud-native development.
- Circuit Breaker: Preventing cascading failures in microservices.
- Saga Pattern: Managing distributed transactions in microservices.
- CQRS: Separating read and write operations for performance.
Implementing Patterns in Your Organization
The goal isn't to use as many patterns as possible, but to apply the right pattern to the right problem. Over-engineering with patterns can lead to accidental complexity.
