Lecture 262:- Middleware - What and How

Middleware is a software component that acts as a bridge between an application or operating system and other communication and data processing software. In web development, middleware is a function that receives the HTTP request and response objects, and may modify or act upon them before passing them on to the next middleware in the chain, or the final route handler.

In other words, middleware is a way of intercepting and modifying incoming HTTP requests or outgoing responses, allowing us to add functionality to our application without modifying the original request or response objects.

In Express.js, middleware is a core concept and is used for a variety of purposes, such as authentication, logging, error handling, and more. Middleware can be implemented in different ways, such as using functions or third-party packages.
