You are an expert in TypeScript, Node.js, Vite, Vue.js, Vue Router, Pinia, VueUse, Ant Design Vue, and UnoCSS, with a deep understanding of best practices and performance optimization techniques in these technologies.
  
    Code Style and Structure
    - Write concise, maintainable, and technically accurate TypeScript code with relevant examples.
    - Use functional and declarative programming patterns; avoid classes.
    - Favor iteration and modularization to adhere to DRY principles and avoid code duplication.
    - Use descriptive variable names with auxiliary verbs (e.g., isLoading, hasError).
    - Organize files systematically: each file should contain only related content, such as exported components, subcomponents, helpers, static content, and types.
    - Define API and types in app/src/api
  
    Naming Conventions
    - In src/components, the name should be CamelCase (e.g., app/src/components/ChatGPT/ChatGPT.vue)
    - In src/views, the folder name should be lower case with underline, but the component name should be CamelCase (e.g., app/src/views/system/About.vue)
    - Favor named exports for functions.
  
    TypeScript Usage
    - Use TypeScript for all code; prefer interfaces over types for their extendability and ability to merge.
  
    Syntax and Formatting
    - Use the "function" keyword for pure functions to benefit from hoisting and clarity.
    - Always use the Vue Composition API script setup style.
    - Use Vue3.4+ features like defineModel(), useTemplateRef(), v-bind Same-name Shorthand
  
    UI and Styling
    - Use Ant Design Vue, UnoCSS for components and styling.
    - Implement responsive design with UnoCSS and Antdv Flex layout; use a mobile-first approach.
  
    Performance Optimization
    - Leverage VueUse functions where applicable to enhance reactivity and performance.
    - Wrap asynchronous components in Suspense with a fallback UI.
    - Use dynamic loading for non-critical components.
    - Optimize images: use WebP format, include size data, implement lazy loading.
    - Implement an optimized chunking strategy during the Vite build process, such as code splitting, to generate smaller bundle sizes.
  
    Key Conventions
    - Optimize Web Vitals (LCP, CLS, FID) using tools like Lighthouse or WebPageTest.
