This is a comprehensive NestJS-based puzzle management system with advanced features for creating, managing, and playing puzzles. The system includes a complete database schema, RESTful APIs, comprehensive testing, and CI/CD pipeline.

🚀 Features Completed

1. Database Design ✅

  • PostgreSQL with comprehensive schema
  • TypeORM integration with entities for:
    • Users with authentication and profiles
    • Puzzles with content, metadata, and versioning
    • Game sessions and progress tracking
    • Leaderboards and achievements
    • Ratings and analytics

2. Puzzle Management System ✅

  • Complete CRUD operations for puzzles
  • Advanced search and filtering with pagination
  • Bulk operations (publish, unpublish, tag management)
  • Analytics and reporting for puzzle performance
  • Content versioning and history tracking
  • Difficulty rating and auto-scaling

3. API Documentation ✅

  • OpenAPI/Swagger integration
  • Comprehensive DTOs with validation
  • Error handling with proper HTTP status codes
  • Authentication guards and role-based access

4. Testing Infrastructure ✅

  • Unit tests with Jest (400+ lines of coverage)
  • Integration tests with database interactions
  • End-to-end tests for complete workflows
  • Performance testing framework
  • Smoke tests for health checks

5. CI/CD Pipeline ✅

  • GitHub Actions workflow
  • Multi-stage pipeline with:
    • Code quality checks (ESLint, Prettier)
    • Security auditing
    • Multi-environment testing
    • Docker builds for multiple platforms
    • Staging and production deployment
    • Performance monitoring

🏗️ Architecture

Core Modules

  • Auth Module: JWT-based authentication with OAuth support
  • Users Module: User management and profiles
  • Puzzles Module: Core puzzle CRUD and management
  • Game Engine: Advanced puzzle mechanics and state management
  • Leaderboard Module: Scoring and rankings
  • Achievements Module: Gamification and rewards
  • Monitoring: Performance tracking and alerting

Database Schema

-- Key entities with relationships
Users (id, email, profile, stats, preferences)
├── Puzzles (content, metadata, analytics)
├── GameSessions (state, progress, performance)
├── Achievements (criteria, rewards, tracking)
└── Leaderboards (scores, rankings, periods)

🛠️ Technology Stack

  • Backend: NestJS, TypeScript, TypeORM
  • Database: PostgreSQL 14+
  • Authentication: JWT, bcrypt, Passport
  • Testing: Jest, Supertest
  • Documentation: Swagger/OpenAPI
  • CI/CD: GitHub Actions, Docker
  • Monitoring: Prometheus, Winston logging
