Uniapp Cloud

When to use this skill

Use this skill whenever the user wants to:

• Use uniCloud cloud development services
• Work with cloud databases (add, query, update, delete data)
• Create and deploy cloud functions
• Use cloud storage for file uploads and management
• Implement datacom components for data binding
• Integrate backend services with uni-app
• Set up uniCloud project and configuration
• Handle cloud database permissions and security

How to use this skill

This skill is organized to match the official uniCloud documentation:

1. Start with setup and project configuration:

   • examples/guide/intro.md
   • examples/guide/project-setup.md
   • examples/guide/cloud-space.md

2. Choose the cloud capability:

   • Database → examples/database/
   • Cloud functions → examples/functions/
   • Storage → examples/storage/
   • Datacom → examples/datacom/
   • Security/permission → examples/security/

3. Open the API reference:

   • api/cloud-api.md

Important Notes:

• This skill focuses on uniCloud integration and usage, not general backend frameworks
• Each example includes official documentation URL
• Follow official permission and security guidance for production

Examples and Templates

Examples

Located in examples/:

• guide/ - Intro, project setup, cloud space creation
• database/ - CRUD, query, index, permissions
• functions/ - Function structure, deploy, call
• storage/ - Upload, download, delete
• datacom/ - datacom components and binding
• security/ - permissions and security rules

Best Practices

1. Security: Always set proper database permissions and rules
2. Performance: Use indexes for frequently queried fields
3. Cost: Optimize cloud function execution time
4. Error handling: Implement proper error handling for all cloud operations
5. Data validation: Validate data before saving to database

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
