Description: Middleware logic refers to the specific operations and conditions defined within middleware functions to handle requests and responses. In the context of web frameworks, middleware acts as an intermediary that processes requests before they reach the final routes. This allows developers to implement functionalities such as authentication, error handling, data validation, and activity logging in a modular and reusable way. Each middleware function can access the request and response objects, as well as the next middleware function in the chain, facilitating the creation of complex workflows. Middleware logic is fundamental to the architecture of modern web applications, as it allows for separation of concerns and improves code maintainability. Additionally, its chained nature allows multiple middleware functions to execute in sequence, providing great flexibility in managing HTTP requests.
