In software development, we often encounter situations where we need to dynamically select algorithms or behaviors. In order to avoid using a large number of conditional statements (such as if-else or switch-case) in the code, the Strategy Pattern provides an elegant solution. Through the Strategy Pattern, we can encapsulate algorithms or behaviors into independent classes and switch them freely at runtime. This article will introduce the concept of the Strategy Pattern in detail, the difference between it and other similar patterns, the problems it solves, Gol…

In software development, when the overall structure of some business logic is the same, but the implementation of some steps needs to be flexibly adjusted, the Template Method Pattern can provide an elegant solution. It defines a common framework for the algorithm and leaves part of the implementation to the subclasses, making the code more flexible and easy to expand. This article will introduce the concept of the Template Method Pattern in detail, the difference between other patterns, the problems it solves, implementation examples in Golang, and practical development...

In software development, we often need to traverse elements in data structures, such as collections, arrays, or linked lists. In order to avoid coupling the traversal logic inside the data structure and improve the readability and scalability of the code, the Iterator Pattern came into being. This article will introduce in detail the concept of the Iterator Pattern, the difference from other patterns, the problems it solves, and how to implement and use the Iterator Pattern in Golang. What is the Iterator Pattern?

In complex software systems, we often need to encapsulate requests as objects to support functions such as parameterization, cancellation, and queuing of requests. The Command Pattern provides an elegant solution to this requirement. It is a behavioral design pattern that decouples requests from executors by encapsulating requests as objects. This article will introduce the concept of the Command Pattern, the difference from other similar patterns, the problems it solves, its implementation in Golang, and the precautions in actual development. …

In complex software systems, we often encounter a scenario where when the state of an object changes, other objects need to be notified so that they can react accordingly. If dependencies are established directly between these objects, the coupling of the system will increase significantly and the code will become difficult to maintain. The Observer Pattern helps us solve this problem elegantly through the publish-subscribe method. This article will introduce the concept of the Observer Pattern, the difference between it and other similar patterns, and how to solve it.

In complex systems, objects often need to communicate with each other frequently. If objects directly reference and depend on each other, the system will become complex and difficult to maintain. In order to solve this coupling problem, the Mediator Pattern came into being. The Mediator Pattern introduces an independent mediator object to manage the interaction between objects, thereby reducing the direct dependency between objects and making the system more flexible. This article will introduce the concept of the Mediator Pattern, the difference from other similar patterns, and the problems it solves.

In the development of complex systems, we often need to face changes in multiple dimensions. The Bridge Pattern is a structural design pattern whose main purpose is to separate the abstract part from the implementation part so that they can change independently. Through the Bridge Pattern, developers can decouple functions in different dimensions, making the system more flexible and scalable. This article will introduce the concept of the Bridge Pattern, the difference from other similar patterns, the problems it solves, implementation examples in Golang, and practical applications...

In software development, the Decorator Pattern is a structural design pattern that improves the flexibility and scalability of the code by dynamically adding new functions to objects. Unlike inheritance, the Decorator Pattern achieves functional enhancement by combining objects, and multiple decorative functions can be selectively superimposed at runtime. This article will introduce the concept of the Decorator Pattern in detail, the difference between it and other similar patterns, the problems it solves, its implementation in Golang, and the precautions in practical applications. …

In modern software development, system performance optimization and resource management are always one of the key concerns of developers. When dealing with a large number of objects or high-frequency creation and destruction operations, the consumption of memory and computing resources is particularly prominent. In order to solve this problem, the Flyweight Pattern came into being. This article will deeply analyze the concept of the Flyweight Pattern, the difference from other similar patterns, the problems it solves, the application in actual development, and the precautions, and show its implementation through a specific example in Golang. What…

In complex system development, we often encounter scenarios where we need to process collections of objects. These objects can be either independent individuals or combinations of other objects. In order to manage and operate these objects more efficiently, we can use the Composite Pattern. This article will introduce in depth the concept of the Composite Pattern, the difference from other similar patterns, the problems it solves, its application in actual development, precautions, and implementation examples in Golang. What is the Composite Pattern? The Composite Pattern…
