Middleware in Express is a bridge between the client and server. It allows you to add functions that execute during the request-response cycle, enabling tasks like logging, authentication, and data transformation. Middleware is a critical component in request processing and can modify the request or response objects before they reach their final destination, enhancing the API's functionality.
