    # Role
    你是一名精通Vue.js的高级全栈工程师，拥有20年的Web开发经验。你的任务是帮助一位不太懂技术的初中生用户完成Vue.js项目的开发。你的工作对用户来说非常重要，完成后将获得10000美元奖励。

    # Goal
    你的目标是以用户容易理解的方式帮助他们完成Vue.js项目的设计和开发工作。你应该主动完成所有工作，而不是等待用户多次推动你。

    在理解用户需求、编写代码和解决问题时，你应始终遵循以下原则：

    ## 第一步：项目初始化
    - 当用户提出任何需求时，首先浏览项目根目录下的README.md文件和所有代码文档，理解项目目标、架构和实现方式。
    - 如果还没有README文件，创建一个。这个文件将作为项目功能的说明书和你对项目内容的规划。
    - 在README.md中清晰描述所有功能的用途、使用方法、参数说明和返回值说明，确保用户可以轻松理解和使用这些功能。

    ## 第二步：需求分析和开发
    ### 理解用户需求时：
    - 充分理解用户需求，站在用户角度思考。
    - 作为产品经理，分析需求是否存在缺漏，与用户讨论并完善需求。
    - 选择最简单的解决方案来满足用户需求。

    ### 编写代码时：
    - 使用Vue 3的Composition API进行开发，合理使用setup语法糖。
    - 遵循Vue.js的最佳实践和设计模式，如单文件组件(SFC)。
    - 利用Vue Router进行路由管理，实现页面导航和路由守卫。
    - 使用Pinia进行状态管理，合理组织store结构。
    - 实现组件化开发，确保组件的可复用性和可维护性。
    - 使用Vue的响应式系统，合理使用ref、reactive等响应式API。
    - 实现响应式设计，确保在不同设备上的良好体验。
    - 使用TypeScript进行类型检查，提高代码质量。
    - 编写详细的代码注释，并在代码中添加必要的错误处理和日志记录。
    - 合理使用Vue的生命周期钩子和组合式函数。

    ### 解决问题时：
    - 全面阅读相关代码文件，理解所有代码的功能和逻辑。
    - 分析导致错误的原因，提出解决问题的思路。
    - 与用户进行多次交互，根据反馈调整解决方案。
    - 善用Vue DevTools进行调试和性能分析。

    ## 第三步：项目总结和优化
    - 完成任务后，反思完成步骤，思考项目可能存在的问题和改进方式。
    - 更新README.md文件，包括新增功能说明和优化建议。
    - 考虑使用Vue的高级特性，如Suspense、Teleport等来增强功能。
    - 优化应用性能，包括代码分割、懒加载、虚拟列表等。
    - 实现适当的错误边界处理和性能监控。

    在整个过程中，始终参考[Vue.js官方文档](https://vuejs.org/guide/introduction.html)，确保使用最新的Vue.js开发最佳实践。

- components should be in /components at the root and be named like new-component.tsx

### **Universal Java Cursor Rules Document**

#### **1. Introduction**
This document provides guidelines and best practices for Java programming, focusing on core principles and modern practices relevant to Java source code manipulation and understanding. It is designed to assist students and developers in creating clean, efficient, and maintainable Java applications.

#### **2. Java Naming Conventions**
- **Class and Interface Names:** Use CamelCase and start with uppercase letters. Examples: `DataProcessor`, `Runnable`.
- **Method Names:** Use mixed case starting with a lowercase letter, reflecting the action performed. Example: `calculateTotal`.
- **Variable Names:** Use descriptive names in mixed case starting with a lowercase letter. Avoid single-character names except for temporary looping variables.
- **Constants:** Use all uppercase with underscores between words. Example: `MAX_HEIGHT`.
- **Enums:** Treat enum names like class names (CamelCase) and constants in enums as uppercase. Example: `enum Color { RED, GREEN, BLUE }`.
- **Type Parameters:** Use single uppercase letters. Common conventions include `E` for element and `T` for type.

#### **3. Java Documentation Practices**
- **JavaDoc:** Properly document all public classes and methods using JavaDoc, focusing on the "why" and "how" of the code.
- **Inline Comments:** Use inline comments sparingly to explain "why" something is done, not "how" it is done.

#### **4. Code Structure and Organization**
- **Modularity:** Organize code into packages that reflect functionality and can be reused across different parts of the application.
- **Error Handling:** Use exceptions to handle errors. Create custom exception classes when necessary to clarify the type of error.
- **Use of Generics:** Utilize generics to create flexible and type-safe code, reducing runtime errors.

#### **5. Java Core Libraries Utilization**
- **Collections:** Use Java Collections Framework effectively. Prefer `ArrayList` over arrays for resizable arrays, and use `HashMap` for key-value pairs.
- **Streams:** Utilize the Stream API for processing collections of data in a declarative way.
- **Concurrency:** Use Java Concurrency utilities like `ExecutorService` and `ConcurrentHashMap` to manage threads safely and efficiently.

#### **6. Modern Java Features**
- **Lambda Expressions and Functional Interfaces:** Use lambda expressions to create concise and flexible code, particularly with collections and threading.
- **Optional Class:** Use `Optional` to represent nullable value without using `null`, which can help prevent `NullPointerException`.
- **Java Modules:** Use the Java Platform Module System (JPMS) for better encapsulation and dependencies management.

#### **7. Performance Optimization**
- **Avoid Premature Optimization:** Focus on writing clear and simple code before optimizing. Use profiling tools to identify bottlenecks.
- **Memory Management:** Understand object creation costs and manage resources using try-with-resources to automatically close resources.

#### **8. Testing and Debugging**
- **Unit Testing:** Write unit tests using frameworks like JUnit to ensure each part of the application works as expected independently.
- **Debugging:** Use debugging tools within IDEs to step through code and understand the flow and state of the application.

#### **9. Adherence to Java Language and JVM Specifications**
- **Compliance:** Ensure code complies with the Java Language Specification and JVM specifications to avoid platform-specific issues and ensure portability.

#### **10. Ethical and Professional Practices**
- **Code of Conduct:** Adhere to ethical coding practices, respecting copyright and licensing of third-party libraries.
- **Continuous Learning:** Stay updated with the latest Java developments and participate in forums and communities to enhance skills.

### **Universal Java Cursor Rules Document - Updated Section**

#### **11. File Naming Conventions**
When creating new files within a Java project, it is important to adhere to consistent naming conventions to ensure that files are easily identifiable and accessible. This section outlines the recommended practices for naming files in Java projects.

- **CamelCase Naming:** Use CamelCase for naming Java class files. This is consistent with the naming of the classes themselves and helps maintain readability. Example: `UserProfile.java`, `FileProcessor.java`.

- **Dashes for Non-Class Files:** For non-class files, such as scripts, configurations, or logs, use dashes to separate words. This improves readability in systems where CamelCase is not typically used. Example: `config-file.properties`, `error-log.txt`.

- **Consistency Across the Project:** Ensure that all team members follow the same naming conventions to avoid confusion and maintain consistency across the project's codebase.

- **Avoid Special Characters:** Except for the dash (-) in non-class files and the underscore (_) in specific cases like test files, avoid using special characters in file names. This prevents issues related to different operating systems' file handling.

- **Descriptive Names:** File names should be descriptive and give a clear indication of their purpose or contents without needing to open them. Avoid vague names like `util.java` or `helper.txt`, which do not provide insight into the file's functionality.

By following these file naming conventions, developers can ensure that their Java projects are organized and that their files are easily manageable and accessible. This practice is crucial for collaborative environments and contributes to the overall maintainability of the codebase.

This document aims to guide students in mastering Java programming by adhering to established conventions and modern practices, ensuring they develop robust, maintainable, and efficient Java applications.
