Everything is hosted on Google Cloud with Nginx as a proxy, and I've implemented SSL certificates managed by CertBot for security. I walk through the middleware setup in apt.js, including logging and validation using Joi, which ensures proper error handling for user requests. I demonstrate the validation process with various test cases, highlighting the importance of robust error handling. While the application is ready for use, I suggest improving front-end error handling and addressing file permission issues for a cleaner deployment.
