Description: Application middleware is a function that acts as an intermediary in processing HTTP requests before they reach the main application. Its purpose is to allow modification, analysis, or management of requests and responses, providing an additional layer of functionality that can be reused across different parts of the application. This type of middleware can be used to implement features such as authentication, activity logging, session management, and input data manipulation. Designed to be modular, application middleware facilitates the separation of concerns, allowing developers to maintain cleaner and more organized code. Additionally, its use contributes to improving the scalability and maintainability of applications, as functionalities can be added or modified without affecting the core of the application. In summary, application middleware is a powerful tool that enables developers to customize the behavior of their web applications efficiently and effectively.
