## General Guidelines
### File Organization
- One component per file
- Use meaningful file names that reflect the component's purpose
- Group related files in appropriate directories
- Maximum file size should not exceed 400 lines
- Keep components focused and single-responsibility
### Naming Conventions
- Use PascalCase for component names: `UserProfile.tsx`
- Use camelCase for file names of non-components: `useAuth.tsx`
- Use kebab-case for CSS files: `button-styles.css`
- Use descriptive names that indicate functionality
## Code Style
### Formatting
- Use 2 spaces for indentation
- Use semicolons at the end of statements
- Use single quotes for strings
- Add trailing commas in objects and arrays
- Maximum line length: 100 characters
### Comments
- Write self-documenting code
- Add comments for complex logic only
- Use JSDoc for component props and functions
- Keep comments up-to-date with code changes
## React Best Practices
### Components
- Use functional components with hooks
- Keep components small and focused
- Extract reusable logic into custom hooks
- Use proper prop typing with TypeScript
- Implement error boundaries for error handling
### Props
- Use destructuring for props
- Define prop types using TypeScript interfaces
- Provide default props when applicable
- Avoid passing unnecessary props
### Hooks
- Follow hooks rules and naming conventions
- Custom hooks should start with 'use'
- Keep hooks focused on specific functionality
- Memoize values and callbacks when needed
## TypeScript Guidelines
### Types and Interfaces
- Use interfaces for object shapes
- Use type aliases for unions and complex types
- Export types/interfaces when shared
- Use meaningful type names
### Type Safety
- Avoid using 'any' type
- Use strict type checking
- Properly type async operations
- Use generics when appropriate
## State Management
### Local State
- Use useState for simple component state
- Use useReducer for complex state logic
- Keep state as close as possible to where it's used
### Global State
- Use React Query for server state
- Follow object syntax for query configuration
- Implement proper loading and error states
- Use proper caching strategies
## Testing
### Unit Tests
- Write tests for all components
- Test component behavior and user interactions
- Use meaningful test descriptions
- Follow AAA pattern (Arrange, Act, Assert)
### Integration Tests
- Test component integration points
- Verify data flow between components
- Test error handling and edge cases
## Performance
### Optimization
- Use React.memo for expensive components
- Implement code splitting with lazy loading
- Optimize images and assets
- Monitor and optimize bundle size
### Best Practices
- Avoid unnecessary re-renders
- Use proper key props in lists
- Implement proper loading states
- Use performance monitoring tools
## Security
### Data Handling
- Sanitize user input
- Implement proper authentication
- Use HTTPS for API calls
- Follow security best practices
### Error Handling
- Implement proper error boundaries
- Log errors appropriately
- Don't expose sensitive information
- Handle API errors gracefully
## Commit Guidelines
### Commit Messages
- Use conventional commits format
- Write clear and concise messages
- Reference issue numbers when applicable
- Keep commits focused and atomic
### Version Control
- Create feature branches from main
- Keep branches up to date
- Review code before merging
- Delete branches after merging
## Documentation
### Code Documentation
- Document complex logic
- Update README.md when needed
- Document API endpoints
- Keep documentation up to date
### Component Documentation
- Document component props
- Provide usage examples
- Document side effects
- Include accessibility considerations
## Accessibility
### Guidelines
- Use semantic HTML elements
- Implement proper ARIA attributes
- Ensure keyboard navigation
- Test with screen readers
### Best Practices
- Provide alt text for images
- Use proper heading hierarchy
- Implement focus management
- Test color contrast
## CSS/Tailwind Guidelines
### Styling
- Use Tailwind CSS classes
- Follow mobile-first approach
- Maintain consistent spacing
- Use design system tokens
### Best Practices
- Keep styles modular
- Avoid !important
- Use proper responsive classes
- Follow BEM naming for custom CSS
## Code Review
### Process
- Review all code changes
- Provide constructive feedback
- Check for best practices
- Verify documentation
### Checklist
- Code follows style guide
- Tests are included
- Documentation is updated
- Performance is considered
- Security is addressed
Remember: These rules are living guidelines. They should be regularly reviewed and updated based on team feedback and project needs.
