Effective Design Patterns in Go
- The article discusses ten design patterns in Go language and their applications in various internet scenarios.
- The Singleton Pattern ensures only one instance of a class is created globally, facilitating global unique control.
- Advantages of the Singleton Pattern include ensuring global uniqueness of resources and providing a convenient global access point.
- The Factory Pattern encapsulates object creation logic and supports polymorphism and easy extension of new products.
- Advantages of the Factory Pattern include separating object creation from usage and complying with the Dependency Inversion Principle.
- The Observer Pattern establishes one-to-many relationships to notify observers of subject state changes, suitable for event-driven scenarios.
- Advantages of the Observer Pattern include broadcast-style event notification and easy expansion of new observer types.
- The Decorator Pattern dynamically adds functions to objects through composition, suitable for scenarios with functional layering.
- Advantages of the Decorator Pattern include avoiding inheritance hierarchy explosion and supporting free combination of functions.
- The Strategy Pattern encapsulates algorithms into independent strategy classes for dynamic switching at runtime.
- Advantages of the Strategy Pattern include decoupling the algorithm from the client and facilitating algorithm extension and replacement.
