We are improving the recommendations.js controller by adding detailed comments and documentation throughout the codebase. The goal is to enhance the code’s readability and maintainability by ensuring that all key components are clearly explained.
Objectives:
High-Level Overview:
Add a comment at the top of the file to explain the overall purpose of the controller.
Function-Level Documentation:
Every function in the controller must be commented with:
Purpose of the function
Explanation of input parameters (if any)
Return values (if applicable)
Database Operations:
Provide detailed comments for key database interactions:
Explain .populate() operations (if used)
Document how data is saved to the database
Provide clear descriptions of how errors are handled and what actions are taken in different error scenarios.
Middleware Logic:
Add comments to describe the purpose of any middleware used, how it processes incoming requests, and how it modifies the request-response lifecycle.
Other changes:
Correcting import for recommendation in the index.js
This documentation effort is intended to make the controller more approachable for developers who may work on it in the future, reducing the learning curve and improving maintainability.
