I completed my post-graduation in 2013 in the engineering field. Engineering is the application of science and math to solve problems. Engineers figure out how things work and find practical uses for scientific discoveries. Scientists and inventors often get the credit for innovations that advance the human condition, but it is engineers who are instrumental in making those innovations available to the world. I love pet animals such as dogs, cats, etc.

Can you answer this question?

Sure, here is the code for an Express middleware to log incoming HTTP requests to the server:

JavaScript

const express = require("express");

const logger = (req, res, next) => {
  const timestamp = new Date().toISOString();
  const method = req.method;
  const url = req.url;
  const ip = req.ip;

  console.log(`${timestamp} ${method} ${url} ${ip}`);
  next();
};

const app = express();

app.use(logger);

app.listen(3000, () => {
  console.log("Server started on port 3000");
});

This code first imports the express module. Then, it defines a middleware function called logger. The logger function takes three arguments: the request object, the response object, and the next middleware function.

The logger function logs the following information about the request:

  • The timestamp of the request
  • The HTTP method of the request
  • The URL of the request
  • The IP address of the client

The logger function then calls the next() function to pass control to the next middleware function in the stack.

Finally, the app creates a route that listens on the / path. This route uses the logger middleware to log incoming requests.

To run this code, you can save it as a file called app.js and then run it from the command line:

node app.js

This will start the Express server on port 3000. You can then make requests to the server and the logger middleware will log the requests to the console.
