When should I use asynchronous middleware in my application?

Asynchronous middleware is useful when you need to handle tasks that take time, like database calls or API requests, without blocking the main thread.

Can you give me an example of when it's necessary?

Sure! If you're fetching user data from an external API, using asynchronous middleware allows your app to continue processing other requests while waiting for the data.

What are the benefits of using it over synchronous middleware?

The main benefits are improved performance and responsiveness, as it prevents the application from freezing while waiting for long-running tasks.

Are there any downsides to using asynchronous middleware?

Yes, it can introduce complexity in error handling and debugging, as the flow of execution is less straightforward than with synchronous middleware.
