Eval is an educational platform designed to facilitate the creation, distribution, and management of training exercises and exams across various disciplines, with a strong emphasis on engineering and software development. It aims to provide a seamless experience for educators and students, offering tools for interactive assessments and real-time evaluation tracking.
Key Features:
- Diverse Question Types: Multiple choice, essay, code writing (multi-language support), database queries (PostgreSQL), and web development tasks
- Code Execution Environment: Monaco editor-based sandbox for multiple programming languages
- Authentication: NextAuth
- Evaluation Lifecycle: Four phases (Draft, In Progress, Grading, Finished)
- Real-time Monitoring: Student progress tracking and analytics
- Automated Grading: Support for various question types with manual override
- Export Capabilities: Results in CSV and PDF formats
Frontend:
- Next.js 14 with App Router
- React 18 for component architecture
- Material-UI (MUI) v5 for base components
- Monaco Editor for code editing
- SWR for data fetching and caching
- NextAuth for authentication
Backend:
- Next.js API Routes
- Prisma ORM for database operations

Code Structure:
- Organize code by feature/module
- Separate business logic from UI components
- Use custom hooks for shared logic
- Implement proper TypeScript types and interfaces
- Follow consistent formatting patterns
- Use proper error boundaries
Testing Requirements:
- Write unit tests for critical functionality
- Implement integration tests for API endpoints
- Test database operations thoroughly
- Ensure proper error handling coverage
Dependencies:
- Use NPM as package manager
- Leverage MUI components for consistent UI
- Minimize external dependencies
- Keep dependencies up to date
- Document any new dependency additions
Security Guidelines:
- Implement proper authentication flows
- Use environment variables for sensitive data
- Follow OWASP security best practices
- Implement proper input validation
- Use prepared statements for database queries
- Implement proper CORS policies
