[FEAT]: API Endpoint for Updating Product

[Blard-omu]

Description

Implement an API endpoint for updating product information. This endpoint allows authenticated users to update product details such as name, description, price, and category.

Endpoint Features

• This endpoint enables authenticated users to update product information in the database.
• Limited to updating valid product details with the provided data.
• Supports updating product name, description, price, and category.

Acceptance Criteria

• [ ] The endpoint should be accessible at PUT /api/v1/products/:product_id.
• [ ] The endpoint should accept HTTP PUTrequests.
• [ ] The endpoint should update the product details in the database with the provided data.
• [ ] The endpoint should return a 200 OK status code with a success message in the response body.

Request Example

PUT /api/v1/products/:product_id
Content-Type: application/json

{
    "product_id": "123",
    "name": "New Product Name",
    "description": "Updated description",
    "price": 19.99,
    "category": "New Category"
  }

Response Example

{
  "status": "success",
  "status_code": 200,
  "message": "Product updated successfully.",
status: "success",
message: "Product updated successfully",
data: {
  "product_id": "123",
  "name": "New Product Name",
  "description": "Updated description",
  "price": 19.99,
  "stock": 50
}
}

Data Validation:

Input Validation

• Confirm that product_id, name, description, price, and category are provided and valid.
• Example: If product_id is invalid or missing, return a 422 status code with an error message.

{
  "status": "Error",
  "status_code": 422,
  "message": "Valid product ID, name, description, price, and stock must be provided."
}

Output Validation

• Ensure the response format is correct and includes appropriate status codes and messages.
• If there is an error in updating the product (e.g., invalid database credentials, network issues), the API should return a 500Internal Server Error status code with an appropriate message.

{
  "status": "Fail",
  "status_code": 500,
  "message": "Failed to update product. Please try again later."
}

Authentication And Authorization

Authentication

• Verify that the user is authenticated before allowing access to the endpoint.
• Example: Use middleware i.e checkAuth to check for a valid authentication token.

Authorization

• Ensure that only authorized users can update product information.
• Example: Check user roles or permissions to confirm authorization.

Error Handling

Error Responses

• Define error responses for common failure scenarios.
• Example: If database credentials are invalid, return a 500 status code with an error message.

{
  "status": "Fail",
  "status_code": 500,
  "message": "Failed to update product. Please try again later."
}

Edge Cases

• Consider edge cases such as missing required fields, and database downtime.
• Example: Handle scenarios where the database is temporarily unavailable.
• Handle case where the product with product_id is not found or no longer exist.

  {
  "status": "unsuccessful",
  "status_code": 404,
  "message": "Product with id '123' not found"
  }

Performance And Security

Performance Considerations

• Review potential performance implications and optimize the API for efficiency.
• Example: Implement rate limiting to prevent abuse.

Security Concerns

• Address security considerations such as data sanitization.
• Example: Sanitize user inputs to prevent injection attacks.

Documentation

API Documentation

• Ensure that API documentation is updated to include details about the new endpoint, request/response formats, error handling, and authentication requirements.

Technical Notes

• Include any additional technical notes or considerations.

Testing Requirements

Unit Tests

• Write unit tests to validate input data and product update logic.

Integration Tests

• Ensure end-to-end functionality is tested with integration tests.

Dependencies And Impact

Dependencies

• Identify dependencies on other tasks or systems, such as user authentication.

Impact Analysis

• Assess the potential impact on other features or components, ensuring that existing functionality is not disrupted.

Your formatting is wrong. Why are you using snake case for the headings?
