Description: Server middleware in the context of web applications refers to a set of functions that execute during the lifecycle of an HTTP request in a server application. These functions act as intermediaries between the client’s request and the server’s response, allowing for tasks such as authentication, data validation, error handling, and manipulation of requests and responses. Middleware can be used to add additional logic to the application, such as session management or HTTP header configuration. In many web application ecosystems, server middleware is often integrated with backend technologies like Node.js and Express, facilitating the creation of full web applications. The modularity of middleware allows developers to reuse code and maintain an organized structure in their applications, improving software maintainability and scalability. In summary, server middleware is essential for managing interactions between the client and server, providing a layer of functionality that enriches the user experience and optimizes application performance.
