What are middlewares in Express?

Can you explain what middlewares are in Express?

Sure! Middlewares in Express are functions that have access to the request and response objects, and they can modify them or end the request-response cycle.

How do I use middlewares in my Express application?

You can use middlewares by calling app.use(middlewareFunction) in your Express app. This will apply the middleware to all incoming requests.

Can you give me an example of a middleware?

Absolutely! A simple example is a logging middleware that logs the request method and URL. Here's how it looks:

app.use((req, res, next) => {
  console.log(`${req.method} ${req.url}`);
  next();
});

What are some common use cases for middlewares?

Common use cases include logging, authentication, error handling, and parsing request bodies.
