HTTP controller for comprehensive lesson management within the WayrApp language learning platform.
This controller serves as the primary REST API interface for lesson operations, providing complete
CRUD functionality and exercise assignment management within the content management system. It handles
HTTP request processing, parameter validation, authentication integration, and response formatting
for all lesson-related endpoints in the WayrApp backend architecture.
The controller manages lessons as part of the hierarchical content structure: Course → Level → Section → Module → Lesson → Exercise.
Each lesson belongs to a specific module and can contain multiple exercises in a defined order.
The controller integrates seamlessly with Express middleware for authentication, authorization,
validation, and error handling while delegating business logic to the service layer.
Key architectural responsibilities include HTTP request processing for lesson CRUD operations,
parameter extraction and validation from URL paths and request bodies, authentication and
authorization enforcement through middleware integration, standardized API response formatting,
comprehensive error handling with proper HTTP status codes, exercise-to-lesson assignment management,
and pagination support for lesson retrieval operations.
The controller follows RESTful conventions and provides endpoints for creating lessons within modules,
retrieving individual lessons and paginated lesson lists, updating lesson properties with validation,
deleting lessons with dependency management, assigning exercises to lessons with order management,
retrieving lesson exercises in their defined sequence, unassigning exercises from lessons,
and reordering exercises within lessons.
