1. Understanding Element Plus

Element Plus is a Vue 3 component library that provides a rich set of UI components following Element Design principles.

Key Concepts:

• Vue 3 Support: Built for Vue 3 with Composition API
• Design System: Follows Element Design language
• Rich Components: 60+ components for various use cases
• Theme Customization: Support for theme customization
• i18n: Internationalization support
• TypeScript: Full TypeScript support

2. Installation

Using npm:

npm install element-plus

Using yarn:

yarn add element-plus

Using pnpm:

pnpm add element-plus

3. Basic Setup

Full Import:

import { createApp } from 'vue'
import ElementPlus from 'element-plus'
import 'element-plus/dist/index.css'
import App from './App.vue'

const app = createApp(App)
app.use(ElementPlus)
app.mount('#app')

On-Demand Import:

import { ElButton, ElInput } from 'element-plus'
import 'element-plus/es/components/button/style/css'
import 'element-plus/es/components/input/style/css'

Examples and Templates

This skill includes detailed examples organized to match the official documentation structure. All examples are in the examples/ directory (see mapping above).

To use examples:

• Identify the topic from the user's request
• Load the appropriate example file from the mapping above
• Follow the instructions, syntax, and best practices in that file
• Adapt the code examples to your specific use case

To use templates:

• Reference templates in templates/ directory for common scaffolding
• Adapt templates to your specific needs and coding style

API Reference

Detailed API documentation is available in the api/ directory, organized to match the official Element Plus API documentation structure:

Component API (api/component-api.md)

• Component props and events
• Component methods
• Component slots

Props and Events (api/props-and-events.md)

• Common props
• Common events
• Event handling

Global Configuration (api/global-config.md)

• Global configuration options
• ConfigProvider usage
• Theme configuration

To use API reference:

1. Identify the API you need help with
2. Load the corresponding API file from the api/ directory
3. Find the API signature, parameters, return type, and examples
4. Reference the linked example files for detailed usage patterns
5. All API files include links to relevant example files in the examples/ directory

Best Practices

1. Use on-demand import: Import only the components you need to reduce bundle size
2. Use Composition API: Prefer Composition API for better code organization
3. Handle events properly: Use proper event handlers for component interactions
4. Customize theme: Use theme variables for customization
5. Follow design specs: Follow Element Design specifications
6. Use TypeScript: Leverage TypeScript for better type safety

能力边界

✅ 适用场景

• 当你需要使用此技能对应的技术栈时
• 当项目需要遵循最佳实践时
• 当需要快速上手或深入理解核心概念时

⚠️ 需要注意

• 复杂业务逻辑需要结合具体场景调整
• 性能优化需要根据实际数据量评估

❌ 不适用场景

• 不相关的技术栈或框架
• 需要完全自定义的特殊场景

常见陷阱 (Gotchas)

1. 版本兼容性：注意框架版本与依赖库的兼容性，不同版本 API 可能有差异
2. 配置文件格式：配置文件格式错误是最常见的问题，建议使用编辑器的语法检查
3. 环境变量：确保所有必要的环境变量已正确设置，敏感信息不要硬编码
4. 依赖冲突：多版本共存时注意依赖冲突，使用 lock 文件锁定版本
5. 性能陷阱：大数据量场景下注意性能优化，避免 N+1 查询等常见问题
