System Architecture

My Dashboard is a comprehensive monorepo application designed for monitoring Cypress test results with automated git hooks for code quality. The system follows a microservices-inspired architecture with clear separation of concerns.

High-Level Architecture​

Component Overview​

🌐 Client Layer​

React Frontend (client/)

  • Technology: React 19, TypeScript, Vite
  • Purpose: User interface for viewing test results, managing applications, and system administration
  • Features:
    • Responsive design for desktop and mobile
    • Real-time dashboard updates
    • Authentication with API key management
    • Interactive charts and data visualization
    • Pull request management interface

🔧 API Layer​

REST API Server (server/)

  • Technology: Node.js, Express, TypeScript
  • Purpose: Core business logic and data management
  • Architecture: Layered architecture with controllers, services, and data access layers

Key Components:

  • Controllers: Handle HTTP requests and responses
  • Services: Business logic and external API integration
  • Middleware: Authentication, rate limiting, error handling
  • Database: MySQL for application data storage

⏰ Background Services​

Cron Jobs (cron/)

  • Technology: Node.js, TypeScript
  • Purpose: Scheduled background tasks and data synchronization
  • Functions:
    • Fetch E2E test results from Cypress Dashboard
    • Generate daily reports and summaries
    • Send notifications for failed tests
    • Clean up old data and cache files

🛠️ Utility Layer​

Scripts (scripts/)

  • Purpose: Development tools, CI/CD utilities, and maintenance scripts
  • Components:
    • Code quality checks (TODO/FIXME detection)
    • Git hooks and commit validation
    • Deployment and backup scripts
    • E2E test execution helpers

Data Flow​

1. Test Result Processing​

2. User Interaction Flow​

3. Notification Flow​

Technology Stack​

Frontend​

  • React 19: Modern React with concurrent features
  • TypeScript: Type safety and developer experience
  • Vite: Fast build tool and development server
  • SWR: Data fetching and caching
  • Material-UI: Component library and design system

Backend​

  • Node.js: JavaScript runtime
  • Express: Web application framework
  • TypeScript: Type safety for server-side code
  • MySQL: Relational database
  • JWT: Token-based authentication (where applicable)

DevOps & Tools​

  • ESLint: Code linting and quality checks
  • Prettier: Code formatting
  • Husky: Git hooks for code quality
  • Jest: Unit testing framework
  • Playwright: End-to-end testing
  • GitHub Actions: CI/CD pipeline

External Integrations​

  • Cypress Dashboard API: Test result data
  • GitHub API: Pull request information
  • JIRA API: Issue tracking integration
  • CircleCI API: Pipeline status monitoring
  • Firebase Cloud Messaging: Push notifications

Security Architecture​

Authentication & Authorization​

  • API Key Authentication: Secure access to API endpoints
  • Rate Limiting: Protection against abuse and DoS attacks
  • Brute Force Protection: Progressive delays and IP blocking
  • Input Validation: Comprehensive request validation
  • CORS Configuration: Controlled cross-origin access

Data Protection​

  • Path Traversal Protection: Secure file system access
  • Protected Files: Critical files cannot be deleted
  • Environment Variables: Secure configuration management
  • Audit Logging: Request and error logging

Scalability Considerations​

Current Architecture​

  • Monorepo Structure: Simplified development and deployment
  • File-based Caching: Simple and effective for current scale
  • Single Server Deployment: Cost-effective and maintainable

Future Scaling Options​

  • Caching Layer: Redis for improved performance
  • Load Balancing: Multiple server instances
  • Microservices: Split components for independent scaling
  • Container Deployment: Docker and Kubernetes support

Deployment Architecture​

Development Environment​

localhost:3000  → API Server
localhost:5173  → React Development Server

Production Environment​

Domain/API      → API Server (Node.js)
Domain/         → Static React Build
Background      → Cron Jobs (Scheduled)

Monitoring & Observability​

Health Monitoring​

  • Health Check Endpoint: /health for service status
  • Error Logging: Comprehensive error tracking
  • Performance Metrics: Response time monitoring
  • Resource Usage: Memory and CPU monitoring

Business Metrics​

  • Test Success Rates: E2E test performance tracking
  • API Usage: Endpoint usage statistics
  • User Activity: Dashboard usage patterns
  • System Alerts: Automated failure notifications

Development Workflow​

Code Quality Pipeline​

  1. Pre-commit Hooks: Linting, formatting, and validation
  2. Automated Testing: Unit and integration tests
  3. E2E Testing: Full application testing
  4. Code Review: Pull request review process
  5. Deployment: Automated deployment pipeline

Data Flow Testing​

  • Unit Tests: Individual component testing
  • Integration Tests: API endpoint testing
  • E2E Tests: Full user journey testing
  • Performance Tests: Load and stress testing

This architecture provides a solid foundation for the current requirements while maintaining flexibility for future growth and enhancements.
