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

• Component API: api/component-api.md - lime-echart component properties and attributes
• Methods API: api/methods-api.md - Available methods for chart manipulation
• Events API: api/events-api.md - Chart events and event handling
• Options API: api/options-api.md - ECharts options configuration reference

Best Practices

1. Platform Compatibility: Test charts on all target platforms (H5, mini-programs, App)
2. Performance: Use lazy loading for charts and optimize data volume
3. Responsive Design: Ensure charts adapt to different screen sizes
4. Data Format: Validate and format data before passing to charts
5. Error Handling: Implement proper error handling for chart initialization and data loading
6. Memory Management: Dispose charts properly when components are destroyed
7. Theme Consistency: Use consistent themes across your application
8. Accessibility: Consider accessibility when designing charts

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
