fix:error_handling

[texora]

Here's an improved version of your code with added error handling, logging, and some best practices for clarity and maintainability.

1. Added winston for logging, which is more flexible and suitable for production environments.
2. Added try-catch blocks to handle errors and return appropriate responses.
3. Added express.json() middleware to handle JSON requests.
4. Replaced multiple if-else statements with a switch statement for better readability.
5. Exits the process if the setup fails to prevent further execution.
