(SP:2) Implement "Get lessons" endpoint

[vlad-khrychov]

Description:

The objective of this task is to implement the backend functionality for retrieving lessons through a new endpoint. This will involve setting up the route, controller, service layer, and tests, as well as updating the Swagger documentation to reflect the new endpoint's capabilities. The implementation should adhere to best practices in terms of security, performance, and code readability.

Requirements:

• Route:

  • Create a new route in the application to handle GET requests for fetching lessons.

• Service Layer:

  • Implement a service that will handle the business logic for retrieving lessons from the database.

• Controller:

  • Develop a controller function to process incoming requests, validate query parameters, and return the appropriate response to the client. The controller should interact with the service layer to fetch the required data.

• Tests:

  • Write tests to ensure the endpoint functions correctly under various scenarios. Tests should cover successful data retrieval, handling of invalid requests.

• Swagger Documentation:

  • Update the Swagger docs to include the new "Get Lessons" endpoint, providing clear information on the request parameters, response structure, and status codes. Ensure the documentation accurately reflects the endpoint's functionality and any query parameters it supports.

• Middleware Integration:

  • Utilize existing middleware for authentication and role-based access control. Ensure that the endpoint is accessible only to authorized roles, such as Tutors.

• Error Handling:

  • Implement robust error handling to manage and respond to exceptions or validation errors, ensuring that the client receives meaningful error messages.
