Node.js API Masterclass with Express and MongoDB - Mongoose Error Handling [1]

The video tutorial covers advanced error handling techniques in a coding context. It begins with catching specific errors in error handlers rather than using a generic catch block. The tutorial explains how to identify different error types, such as cast errors, and how to create and set error messages for user responses. It also demonstrates implementing error responses directly in the error handler and refactoring error handling in controller methods. The video concludes by preparing to handle validation errors in the next session.
