🇨🇳中文介绍

设计模式实现

概述

应用经过验证的设计模式，创建可维护、可扩展和可测试的代码架构。

何时使用

解决常见的架构问题
使代码更易于维护和测试
实现可扩展的插件系统
解耦组件
遵循 SOLID 原则
代码审查中发现架构问题

快速开始

最小工作示例：

class DatabaseConnection {
  private static instance: DatabaseConnection;
  private connection: any;

  private constructor() {
    this.connection = this.createConnection();
  }

  public static getInstance(): DatabaseConnection {
    if (!DatabaseConnection.instance) {
      DatabaseConnection.instance = new DatabaseConnection();
    }
    return DatabaseConnection.instance;
  }

  private createConnection() {
    return {
      /* connection logic */
    };
  }
}

// Usage
const db1 = DatabaseConnection.getInstance();
const db2 = DatabaseConnection.getInstance();
// ... (see reference guides for full implementation)

Design Patterns Implementation

Overview

Quick Start
Reference Guides
Best Practices

Overview

Apply proven design patterns to create maintainable, extensible, and testable code architectures.

When to Use

Solving common architectural problems
Making code more maintainable and testable
Implementing extensible plugin systems
Decoupling components
Following SOLID principles
Code reviews identifying architectural issues

Quick Start

Minimal working example:

class DatabaseConnection {
  private static instance: DatabaseConnection;
  private connection: any;

  private constructor() {
    this.connection = this.createConnection();
  }

  public static getInstance(): DatabaseConnection {
    if (!DatabaseConnection.instance) {
      DatabaseConnection.instance = new DatabaseConnection();
    }
    return DatabaseConnection.instance;
  }

  private createConnection() {
    return {
      /* connection logic */
    };
  }
}

// Usage
const db1 = DatabaseConnection.getInstance();
const db2 = DatabaseConnection.getInstance();
// ... (see reference guides for full implementation)

Best Practices

✅ DO

Choose patterns that solve actual problems
Keep patterns simple and understandable
Document why patterns were chosen
Consider testability
Follow SOLID principles
Use dependency injection
Prefer composition over inheritance

❌ DON'T

Apply patterns without understanding them
Over-engineer simple solutions
Force patterns where they don't fit
Create unnecessary abstraction layers
Ignore team familiarity with patterns
