## 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 ## Resources - **Official Documentation**: https://doc.dcloud.net.cn/uniCloud/ - **Cloud Database**: https://doc.dcloud.net.cn/uniCloud/database.html - **Cloud Functions**: https://doc.dcloud.net.cn/uniCloud/cf-functions.html - **Cloud Storage**: https://doc.dcloud.net.cn/uniCloud/storage.html ## Keywords unicloud, uniCloud, cloud development, cloud database, cloud functions, cloud storage, datacom, 云开发, 云数据库, 云函数, 云存储 ## 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 ## 使用流程 ### Step 1: 环境准备 确保开发环境已安装必要的依赖和工具。 ### Step 2: 配置初始化 根据项目需求进行基础配置。 ### Step 3: 核心功能使用 按照示例代码实现核心功能。 ### Step 4: 测试验证 运行测试确保功能正常。 ### Step 5: 部署上线 完成开发后进行部署和监控。
