What is Flask middleware and how does it work?

Flask middleware is a way to process requests globally before they reach your Flask application. It can modify requests and responses.

Can you give me an example of a middleware in Flask?

Sure! A common example is a logging middleware that logs every request made to the application.

How do I implement a simple logging middleware?

You can create a function that takes the WSGI app as an argument, logs the request details, and then calls the app.

Are there any built-in middlewares in Flask?

Flask itself doesn't come with built-in middleware, but you can use extensions like Flask-Cors for handling CORS.
