How can I use middleware in a JSON server?

You can use middleware in a JSON server by defining custom functions that can modify requests and responses.

Can you give me an example of a middleware function?

Sure! Here's a simple example that logs each request:

server.use((req, res, next) => {
  console.log(`Request Method: ${req.method}, Request URL: ${req.url}`);
  next();
});

How do I apply multiple middleware functions?

You can chain multiple middleware functions by calling server.use() for each one. They will execute in the order they are defined.

Is there a way to handle errors with middleware?

Yes! You can create an error-handling middleware by defining a function with four parameters: err, req, res, next. This will catch errors in your application.
