PadelHUB Development Assistant

Project Overview

You are assisting with PadelHUB, a comprehensive padel management platform built with:

• Frontend: Angular 18+ with TypeScript, Angular Material, PWA capabilities
• Backend: NestJS with TypeScript, MongoDB, JWT authentication
• Architecture: Full-stack TypeScript application with role-based access control

Good Practices & Guidelines

Code Quality Standards

1. TypeScript Best Practices

   • Use strict type checking and avoid any types
   • Implement proper interfaces and type definitions
   • Follow naming conventions: PascalCase for classes/interfaces, camelCase for variables/functions
   • Use generic types where appropriate for reusability

2. Angular Specific Guidelines

   • Follow Angular style guide and conventions
   • ALWAYS create separate .html and .scss files - never use inline templates or styles in TypeScript files
   • Use reactive forms over template-driven forms
   • Implement proper component lifecycle hooks
   • Use OnPush change detection strategy where possible
   • Lazy load feature modules for better performance
   • Use Angular Material components consistently

3. NestJS Backend Standards

   • Use dependency injection and decorators properly
   • Implement proper error handling with custom exceptions
   • Use DTOs for data validation and transformation
   • Follow RESTful API design principles
   • Implement proper authentication and authorization guards

Security Practices

1. Authentication & Authorization

   • Implement proper JWT token handling
   • Use role-based access control (RBAC)
   • Validate user permissions on both frontend and backend
   • Secure sensitive routes with guards

2. Data Protection

   • Sanitize user inputs to prevent XSS attacks
   • Use parameterized queries to prevent injection attacks
   • Implement proper CORS configuration
   • Hash passwords with bcrypt

Performance Optimization

1. Frontend Performance

   • Use OnPush change detection strategy
   • Implement lazy loading for routes and modules
   • Optimize bundle size with tree shaking
   • Use trackBy functions in *ngFor loops
   • Implement virtual scrolling for large lists

2. Backend Performance

   • Use proper database indexing
   • Implement caching strategies where appropriate
   • Use pagination for large data sets
   • Optimize database queries

Testing Standards

1. Unit Testing

   • Write tests for all business logic
   • Use Jest for backend testing
   • Use Jasmine/Karma for Angular testing
   • Aim for >80% code coverage

2. Integration Testing

   • Test API endpoints thoroughly
   • Test component interactions
   • Mock external dependencies

Code Organization

1. File Structure

   • Follow feature-based folder structure
   • Keep components, services, and models organized
   • Use barrel exports (index.ts) for clean imports
   • Separate shared utilities and components

2. Naming Conventions

   • Use descriptive, meaningful names
   • Follow Angular/NestJS naming conventions
   • Use consistent naming across the application

Error Handling

1. Frontend Error Handling

   • Implement global error handler
   • Show user-friendly error messages
   • Log errors for debugging
   • Handle network errors gracefully

2. Backend Error Handling

   • Use custom exception filters
   • Return consistent error responses
   • Log errors with appropriate detail
   • Validate input data properly

Documentation Standards

1. Code Documentation

   • Write clear, concise comments for complex logic
   • Document API endpoints with proper descriptions
   • Use JSDoc for function and class documentation
   • Keep README files updated

2. API Documentation

   • Use Swagger/OpenAPI for API documentation
   • Document request/response schemas
   • Include example requests and responses

Version Control Practices

1. Git Workflow

   • Use meaningful commit messages
   • Follow conventional commit format
   • Create feature branches for new development
   • Use pull requests for code review

2. Code Review Guidelines

   • Review for code quality and standards
   • Check for security vulnerabilities
   • Ensure proper testing coverage
   • Verify documentation updates

Response Style

• Always respond in Spanish language
• Only generate markdown files and scripts when they are strictly informative or necessary
• Always use Git Bash compatible commands when providing terminal instructions
• Always execute commands directly using tools instead of just suggesting them
• Automatically read and update the context log file (docs/development-log.md) at the start of each interaction
• Maintain a context log file (docs/development-log.md) with all actions performed for future reference
• Provide clear, actionable guidance
• Include code examples when helpful
• Reference specific files and line numbers when applicable
• Suggest improvements for code quality and performance
• Consider security implications in all recommendations
• Be thorough but concise in explanations

Focus Areas

• Full-stack TypeScript development
• Angular and NestJS best practices
• MongoDB database optimization
• Role-based access control implementation
• Performance optimization techniques
• Security and authentication patterns
• Testing strategies and implementation
• Code maintainability and scalability
