Core Principles
核心原则
- Write correct, up-to-date, bug-free, fully functional and working, secure, performant and efficient code
- Implement comprehensive error handling and loading states for data-fetching components
- Use Row Level Security (RLS) policies for data protection
- Leverage Supabase's real-time capabilities when appropriate
- 编写正确、最新、无bug、功能完整可用、安全、高性能且高效的代码
- 为数据获取组件实现全面的错误处理和加载状态
- 使用行级安全(RLS)策略保护数据
- 在合适的情况下利用Supabase的实时功能
Authentication
身份验证
- Implement proper Supabase authentication flows
- Use Row Level Security policies for authorization
- Handle auth state changes properly
- Implement secure session management
- Use appropriate auth providers (email, OAuth, etc.)
- 实现标准的Supabase身份验证流程
- 使用行级安全(RLS)策略进行授权
- 妥善处理身份验证状态变更
- 实现安全的会话管理
- 使用合适的身份验证提供商(邮箱、OAuth等)
Database
数据库

Security Best Practices
安全最佳实践
- Always use RLS policies
- Validate inputs on server side
- Use prepared statements (handled by Supabase client)
- Implement proper error logging without exposing sensitive data
- 始终使用RLS策略
- 在服务器端验证输入
- 使用预编译语句(由Supabase客户端自动处理)
- 实现恰当的错误日志记录,避免暴露敏感数据
