 ## Key Design Decisions
 ### Backend Architecture
 - **Async/await**: All I/O operations are async for performance
 - **In-memory storage**: Simple start, easy to replace with database
 - **Sandboxed execution**: Each project isolated in filesystem
 - **No direct Helm API**: Uses CLI for maximum compatibility
 ### Frontend Architecture
 - **Functional components**: Modern React with hooks
 - **No TypeScript**: Per requirements, uses JavaScript
 - **Component composition**: Small, focused components
 - **CSS modules approach**: Separate CSS per component
 - **Monaco Editor**: Industry-standard editor with LSP support
 ### Security Architecture
 - **Defense in depth**: Multiple layers of validation
 - **Principle of least privilege**: Minimal permissions
 - **Input validation**: All inputs validated
 - **Safe defaults**: Secure by default configuration
 ### Scalability Considerations
 - **Stateless backend**: Easy horizontal scaling
 - **Async operations**: High concurrency support
 - **Docker containers**: Easy deployment and scaling
 - **Database-ready**: Structure supports easy DB integration
 ## Development Workflow
 ### Local Development
 1. Start backend: `uvicorn main:app --reload`
 2. Start frontend: `npm run dev`
 3. Make changes (hot reload active)
 4. Test locally
 5. Commit and push
 ### Docker Development
 1. Start: `docker-compose up`
 2. Make changes (hot reload via volumes)
 3. Test in containers
 4. Rebuild if needed: `docker-compose up --build`
 ### Production Build
 1. Build images: `docker-compose -f docker-compose.prod.yml build`
 2. Test locally: `docker-compose -f docker-compose.prod.yml up`
 3. Deploy to production environment
 4. Monitor health checks
 ## Extension Points
 ### Adding New Features
 **New Backend Endpoint**
 1. Add route in `main.py`
 2. Add Pydantic model if needed
 3. Implement handler function
 4. Add API client method in `frontend/src/api.js`
 5. Update documentation
 **New Frontend Component**
 1. Create component file in `src/components/`
 2. Create corresponding CSS file
 3. Import in parent component
 4. Add props and state management
 5. Test in isolation
 **New Validation Rule**
 1. Add to `validateYaml()` in `YamlEditor.jsx`
 2. Add backend validation in `main.py`
 3. Update error messages
 4. Add tests
 **Database Integration**
 1. Add SQLAlchemy models
 2. Add Alembic migrations
 3. Replace in-memory `projects_db`
 4. Update all CRUD operations
 5. Add connection pooling
 6. Update docker-compose with database service
 ## Performance Considerations
 ### Backend
 - Async I/O for non-blocking operations
 - Command timeouts prevent hanging
 - Temporary file cleanup
 - Efficient YAML parsing
 ### Frontend
 - Code splitting (Vite handles this)
 - Lazy loading of Monaco Editor
 - Debounced filter inputs
 - Virtual scrolling for large lists (future)
 ### Docker
 - Multi-stage builds reduce image size
 - Layer caching optimizes builds
 - Resource limits prevent exhaustion
 - Health checks ensure availability
 ## Testing Strategy
 ### Backend Tests (Future)
 - Unit tests for helper functions
 - Integration tests for API endpoints
 - Security tests for validation
 - Performance tests for Helm operations
 ### Frontend Tests (Future)
 - Component unit tests
 - Integration tests for pages
 - E2E tests for critical flows
 - Accessibility tests
 ### Manual Testing Checklist
 - [ ] Upload various chart formats
 - [ ] Render with different options
 - [ ] Edit and save YAML
 - [ ] Export and validate
 - [ ] Filter resources
 - [ ] Error handling
 - [ ] Cross-browser testing

 # HelmView Quick Start Guide
 ## 🚀 Get Started in 3 Steps
 ### Step 1: Start the Application
 ```bash
 # Clone and enter directory
 cd helmview
 # Start with Docker Compose
 docker-compose up --build
 ```
 Wait for both services to start (2-3 minutes first time).
 ### Step 2: Open HelmView
 Open your browser and navigate to:
 - **Frontend**: http://localhost:5173
 - **API Docs**: http://localhost:8000/docs
 ### Step 3: Create Your First Project
 1. **Create a project**
   - Click "Create Project"
   - Enter name: "my-first-chart"
   - Click "Create Project"
 2. **Upload a Helm chart**
   - Get a sample chart:
     ```bash
     helm create sample-chart
     helm package sample-chart
     ```
   - Click "Upload Chart"
   - Upload the `sample-chart-0.1.0.tgz` file
 3. **Render the chart**
   - Click "Render"
   - Keep default settings
   - Click "Render Chart"
 4. **Edit resources**
   - Click on any resource card (e.g., Deployment)
   - Switch to "YAML" tab
   - Edit the YAML (try changing replicas)
   - Click "Save Changes"
 5. **Export modified chart**
   - Click "Export Chart"
   - Wait for validation
   - Click "Download Chart"
 ## 📋 What You Get
 After following these steps, you'll have:
 - ✅ A running HelmView instance
 - ✅ A modified Helm chart with your changes
 - ✅ A validated, packaged chart ready to deploy
 ## 🎯 Next Steps
 - **Filter Resources**: Use the filters to find specific resources
 - **Batch Edits**: Edit multiple resources and export them all
 - **Re-render**: Try different values overrides
 - **Multiple Projects**: Create more projects for different charts
 ## 💡 Tips
 ### Getting a Helm Chart to Test
 ```bash
 # Create a new chart
 helm create my-app
 # Package it
 helm package my-app
 # Upload my-app-0.1.0.tgz to HelmView
 ```
 ### Using Existing Charts
 ```bash
 # Add Helm repo
 helm repo add bitnami https://charts.bitnami.com/bitnami
 helm repo update
 # Pull a chart
 helm pull bitnami/nginx --untar
 # Package it
 helm package nginx
 # Upload nginx-*.tgz to HelmView
 ```
 ### Common Edits to Try
 - Change `spec.replicas` in Deployments
 - Add environment variables
 - Modify service ports
 - Add labels and annotations
 - Change resource limits
 ## 🐛 Troubleshooting
 **Application won't start?**
 ```bash
 # Check Docker is running
 docker ps
 # View logs
 docker-compose logs backend
 docker-compose logs frontend
 # Restart clean
 docker-compose down -v
 docker-compose up --build
 ```
 **Can't upload chart?**
 - Ensure file is `.tgz`, `.tar.gz`, or `.zip`
 - Max size is 100MB
 - Chart must have valid `Chart.yaml`
 **Export fails?**
 - Check all YAML edits are saved

 **HelmView** is a production-ready web-based visual Helm chart editor and validator. Upload existing Helm charts, render them, visualize all Kubernetes resources, edit them safely with autocomplete + validation, and export fully working Helm charts that pass all validation checks.
 ## 🚀 Features
 ### Core Functionality
 - **📤 Chart Upload**: Upload Helm charts as `.tgz`, `.tar.gz`, or `.zip` archives
 - **🔄 Helm Rendering**: Render charts with custom values, release names, and namespaces
 - **👀 Visual Resource View**: Grid view of all Kubernetes resources with filtering
 - **✏️ YAML Editor**: Monaco editor with:
  - Real-time syntax highlighting
  - Kubernetes-aware autocomplete
  - Schema-based validation
  - Inline error markers
 - **📦 Safe Export**: Export modified charts with automatic validation
 - **🔍 Advanced Filtering**: Filter resources by kind, name, namespace, and labels
 - **📊 Resource Tracking**: Track modifications and view diffs
 ### Security Features
 - ✅ Sandboxed filesystem per project
 - ✅ Protection against zip-slip attacks
 - ✅ File size limits (100MB default)
 - ✅ Execution timeouts for Helm commands
 - ✅ No user code execution - only Helm template/lint
 - ✅ Input validation and YAML schema checking
 ## 📋 Tech Stack
 ### Frontend
 - **React 18** with Vite (JavaScript)

 ## 🧪 Development
 ### Local Development (without Docker)
 #### Backend
 ```bash
 cd backend
 python -m venv venv
 source venv/bin/activate  # On Windows: venv\Scripts\activate
 pip install -r requirements.txt
 uvicorn main:app --reload --port 8000
 ```
 #### Frontend
 ```bash
 cd frontend

 # Backend tests (add pytest)
 cd backend
 pytest
 # Frontend tests (add vitest)
 cd frontend
 npm run test
 ```
 ## 📊 Future Enhancements
 ### Planned Features
 - [ ] **Database Integration**: PostgreSQL for project history, versioning, and diffs
 - [ ] **Undo/Redo**: Per-resource undo/redo functionality
 - [ ] **Template Source Tracking**: Show which Helm template produced each resource
 - [ ] **Values Highlighting**: Highlight values.yaml keys used by resources
 - [ ] **Multi-user Support**: User authentication and project sharing
 - [ ] **Diff Viewer**: Visual diff between original and modified resources
 - [ ] **Form Editors**: GUI editors for common resource types
 - [ ] **Search**: Full-text search across all resources
 - [ ] **Export to Git**: Push modified charts directly to Git repositories
 ## 🐛 Troubleshooting
 ### Common Issues
 **1. Backend fails to start**
 ```bash
 # Check Helm installation
 docker-compose exec backend helm version
 # Check logs
 docker-compose logs backend
 ```
 **2. Frontend can't connect to backend**
 - Verify backend is running: `curl http://localhost:8000/health`
 - Check CORS settings in backend/main.py
 - Ensure `VITE_API_URL` is set correctly
 **3. Chart upload fails**
 - Verify file size is under 100MB
 - Ensure file is valid `.tgz`, `.tar.gz`, or `.zip`
 - Check backend logs for detailed error
 **4. Export fails validation**
 - Review helm lint output in the modal
 - Check for YAML syntax errors
 - Ensure all resources have required fields

 ## Reporting a Vulnerability
 We take security vulnerabilities seriously. If you discover a security issue, please follow these steps:
 ### DO NOT
 - Open a public GitHub issue
 - Discuss the vulnerability publicly
 - Exploit the vulnerability
 ### DO
 1. **Email**: Send details to security@helmview.io (if available) or create a private security advisory on GitHub
 2. **Include**:
   - Description of the vulnerability
   - Steps to reproduce
   - Potential impact
   - Suggested fix (if any)
 3. **Wait**: Allow up to 48 hours for initial response
 ### What to Expect
 - **Initial Response**: Within 48 hours
 - **Status Update**: Within 7 days
 - **Fix Timeline**: Depends on severity
  - Critical: 1-7 days
  - High: 7-30 days
  - Medium: 30-90 days
  - Low: Next release cycle
 ## Security Best Practices for Deployment
 ### Production Deployment
 1. **Authentication**: Implement user authentication (not included by default)
 2. **HTTPS**: Always use TLS/SSL in production
 3. **Firewall**: Restrict backend access to frontend only
 4. **Secrets**: Use environment variables or secret management
 5. **Updates**: Keep dependencies updated regularly
 6. **Monitoring**: Set up security monitoring and logging
 7. **Backups**: Regular backups of project data
 8. **Resource Limits**: Configure Docker resource limits
 ### Network Security
 ```yaml
 # Recommended docker-compose.yml additions
 services:
  backend:
    networks:
      - internal
  frontend:
    networks:
      - internal
      - external
 networks:
  internal:
    internal: true
  external:
 ```
 ### Environment Hardening
 ```bash
 # Set restrictive file permissions
 chmod 600 .env
 # Use non-root user in containers
 # (already implemented in Dockerfiles)
 # Enable Docker security features
 docker run --security-opt=no-new-privileges --cap-drop=ALL
 ```
 ### Rate Limiting
 Consider implementing rate limiting for production:
 - File uploads: 10 per hour per IP
 - API requests: 100 per minute per IP
 - Chart renders: 20 per hour per project
 ### Database Security (when using PostgreSQL)
 - Use strong passwords
 - Enable SSL connections
 - Regular security updates
 - Principle of least privilege for DB users
 - Regular backups with encryption
 ## Known Limitations
 ### Current Security Limitations
 1. **No Authentication**: Users must implement their own auth layer
 2. **No Rate Limiting**: Should be added for production
 3. **No Audit Logging**: Consider adding for compliance
 4. **Shared Resources**: All users share the same backend (multi-tenancy not implemented)
 ### Helm Security Considerations
 - Helm charts may contain malicious templates (mitigated by no hook execution)
 - Large charts may consume significant resources (mitigated by timeouts)
 - Chart dependencies are not validated (user responsibility)
 ## Security Checklist for Production
 - [ ] Enable HTTPS/TLS
 - [ ] Implement authentication & authorization
 - [ ] Set up rate limiting
 - [ ] Configure firewall rules
 - [ ] Set resource limits
 - [ ] Enable audit logging
 - [ ] Set up monitoring & alerts
 - [ ] Regular security updates
 - [ ] Backup strategy in place
 - [ ] Incident response plan defined
 - [ ] Security review completed
 - [ ] Penetration testing performed
 ## Compliance
 HelmView does not currently provide built-in compliance features for:
 - HIPAA
 - PCI-DSS
 - SOC 2
 - GDPR (data handling must be implemented separately)
 Users requiring compliance should implement additional controls.
