What is the impact of middleware on routing in web applications?

Middleware plays a crucial role in routing by processing requests before they reach the final route handler. It can modify requests, add authentication, log information, and more.

Can you give me an example of middleware affecting routing?

Sure! For instance, an authentication middleware checks if a user is logged in before allowing access to certain routes. If not authenticated, it can redirect them to a login page.

Are there different types of middleware?

Yes, there are several types, including logging middleware, error handling middleware, and security middleware, each serving different purposes in the request lifecycle.

How do I implement middleware in my application?

You can implement middleware by defining a function that takes the request, response, and next function as parameters, then using it in your routing setup.
