    • Implement logic to prevent double-booking conflicts.

  • Booking Management

    • Allow customers to view, modify, or cancel their bookings.

Employee Features

  • Employee Login

    • Develop login functionality for employees.

  • Schedule Management

    • Create an interface for employees to view and manage their schedules.

  • Availability Settings

    • Allow employees to set their availability and block out times.

Admin Features

    • Implement functionality to add, modify, or remove employee accounts.

  • Reporting

    • Create reporting tools to generate and export reports on bookings, revenue, and employee performance.

  • Service Management

    • Develop functionality to add or update services, including pricing and duration.

Security Enhancements

  • Authentication and Authorization
    • Implement bcrypt for password hashing.
    • Implement JWT refresh tokens for secure API access.
    • Implement role-based access control (RBAC) to restrict resources based on user roles.
  • Input Validation
    • Use class-validator to sanitize and validate all user inputs.
    • Prevent SQL injection and XSS attacks.
  • Data Protection
    • Encrypt sensitive data at rest and in transit using HTTPS with TLS.
  • Rate Limiting
    • Implement rate limiting to protect against brute-force attacks.
  • Audit Logging
    • Maintain logs of critical actions for auditing purposes.

Scalability Improvements

  • Stateless Backend
    • Design the backend to be stateless to facilitate horizontal scaling.
  • Load Balancing
    • Use a load balancer to distribute traffic across multiple server instances.
  • Caching
    • Implement caching for frequent read operations using Redis.
  • Database Optimization
    • Use indexing and query optimization techniques.
    • Consider read replicas for PostgreSQL.
  • Asynchronous Processing
    • Use message queues (e.g., RabbitMQ) for background tasks like sending notifications.

Testing Improvements

  • Unit Tests
    • Write comprehensive unit tests for all services, controllers, guards, and pipes.
  • Integration Tests
    • Implement integration tests for API endpoints and database operations.
  • End-to-End Tests
    • Create end-to-end tests for critical user flows using Cypress.

Deployment Automation

  • CI/CD Pipeline
    • Set up a CI/CD pipeline using GitHub Actions or similar.
    • Automate building, testing, and deployment processes.
  • Infrastructure as Code (IaC)
    • Use Terraform or similar to manage infrastructure.

Monitoring and Logging

  • Application Monitoring
    • Use tools like Prometheus and Grafana to monitor application performance.
  • Error Tracking
    • Implement Sentry or similar for error logging.
  • Health Checks
    • Set up endpoint and infrastructure health checks.
