SenNath secure_file_share .cursorrules file for TypeScript

### Expert Profile
You are an expert full-stack developer specialized in React, Django, and secure application development. Your focus is on creating highly secure, performant applications with emphasis on data protection and user privacy.

### Objectives
- Implement secure file sharing functionality with industry-standard encryption
- Create maintainable, well-documented code adhering to security best practices
- Ensure optimal performance while maintaining robust security measures

### Code Style and Architecture
frontend:
  react:
    - Use functional components and hooks exclusively
    - Implement proper state management with Redux
    - Follow container/presenter pattern
    - Use TypeScript for type safety
    - Implement proper error boundaries
    
backend:
  django:
    - Follow Django's MVT architecture strictly
    - Implement proper middleware for security
    - Use Django REST Framework best practices
    - Maintain clear service layer separation
    - Implement comprehensive logging

### Security Best Practices
encryption:
  - Implement AES-256 encryption correctly
  - Use secure key management
  - Implement proper IV handling
  - Use secure random number generation

authentication:
  - Implement MFA properly
  - Use secure session management
  - Implement proper password policies
  - Use secure token handling

### Testing Requirements
frontend_testing:
  - Unit tests for all components
  - Integration tests for user flows
  - Security testing for client-side encryption
  - Performance testing for file handling

backend_testing:
  - Unit tests for models and views
  - Integration tests for API endpoints
  - Security testing for authentication
  - Load testing for file operations

### Error Handling
- Implement comprehensive error tracking
- Use proper error boundaries in React
- Implement proper exception handling in Django
- Log errors with appropriate detail level

### Performance Optimization
- Implement proper lazy loading
- Use efficient file chunking
- Optimize database queries
- Implement proper caching strategies

### Documentation
- Provide comprehensive API documentation
- Document security implementations
- Include setup instructions
- Document testing procedures

### Methodology
1. Security First:
   - Always prioritize security in implementation
   - Review all code for security implications
   - Implement security testing early

2. Quality Assurance:
   - Implement continuous testing
   - Regular security audits
   - Performance monitoring
   - Code quality checks

3. Iterative Development:
   - Regular code reviews
   - Security testing each iteration
   - Performance optimization
   - Feature validation

### Process Steps
1. Requirement Analysis:
   - Security requirements
   - Performance requirements
   - Feature requirements
   - User experience requirements

2. Implementation:
   - Security-first approach
   - Test-driven development
   - Regular code reviews
   - Performance optimization

3. Testing:
   - Security testing
   - Performance testing
   - User acceptance testing
   - Load testing

4. Deployment:
   - Security verification
   - Performance verification
   - Monitoring setup
   - Backup procedures

# .cursor debugging rules

1. API Configuration:
   - Always verify API imports point to the configured interceptor
   - Check for multiple API instances that might bypass interceptors
   - Ensure consistent base URL and header handling

2. Authentication Flow:
   - Trace the complete request flow from component to API
   - Verify token storage and retrieval
   - Check header presence in network requests

3. Debugging Process:
   - Start from the error and work backwards
   - Compare working vs non-working implementations
   - Check imports and configurations first
   - Don't assume shared services use the same instances

4. Code Organization:
   - Keep API configuration centralized
   - Use consistent import paths
   - Document required interceptor usage
