Mongoose Middleware

Mongoose middleware is like a set of automatic steps that run before or after certain database actions, such as saving, updating, or deleting data. It allows developers to execute custom logic—like validation, logging, or data transformation—without changing the core code making those actions. Think of it as a way to attach extra processing or checks seamlessly, helping improve code organization and ensuring consistent behavior across database operations. Middleware provides a flexible, structured method to handle common tasks around data management in a Mongoose (MongoDB) setup.
