Add review routes with authentication and validation for CRUD operations

[PhamelaMhlaba]

Overview: This pull request introduces a series of routes for managing reviews in the application, including creating, retrieving, updating, and deleting reviews. Key features include authentication and input validation to ensure secure and clean data handling.

Key Features:

Authentication:

• Users must be authenticated (using JWT token validation) to create, update, or delete reviews.

Validation:

• Reviews are validated for content length (minimum of 5 characters) and rating (an integer between 1 and 5).

• Review ID parameters are validated to ensure they follow the correct MongoDB ObjectId format.

Error Handling:

• Implemented a middleware (handleValidationErrors) that ensures all validation errors are caught and returned with appropriate error messages before proceeding with the controller logic.

Specific Routes:

POST /reviews: Create a new review (authenticated, with content and rating validation). GET /reviews: Retrieve all reviews (no authentication required). GET /reviews/:id: Retrieve a single review by ID (ID validation included). PUT /reviews/:id: Update an existing review (authenticated, with optional validation for content and rating). DELETE /reviews/:id: Delete a review by its ID (authenticated, with ID validation).

Next Steps:

Please review the code for structure, readability, and any potential improvements. Confirm whether the validation and authentication checks align with our security and data integrity standards.
