Implementation of view a Single Product Function

[maxCastro1]

Description

This PR includes the implementation of the viewSingleProduct function in the Product service. The function is designed to fetch and return the details of a single product from the database.

Functionality

• Function Definition: Defined the viewSingleProduct function which is an asynchronous function that takes in a request and response object.
• Product ID Extraction: Extracted the product ID from the request parameters.
• UUID Validation: Added a check to validate the UUID of the product before querying the database. This helps prevent errors when an invalid UUID is provided.
• Database Query: Used the findOneBy method from the typeorm library to fetch the product from the database using the product ID.
• Error Handling: Added error handling to return a 404 status code and error message when the product is not found, and a 500 status code and error message for other errors.
• Product Expiration Check: Added a check for the product’s expiration date. If the product is expired, the function sends a response with the message ‘Product expired’.
• Response: If the product is found and not expired, the function sends a 200 status code and the product data as a JSON response.

Test

Tests have been added to verify the new functionality:

• A test to check if the endpoint correctly returns a single product.
• A test to check if the endpoint correctly handles the case where the product does not exist.
• A test to check if the endpoint correctly handles the case where the product is expired.
