})

How does http.listen work?

The http.listen method creates a new HTTP server and listens for incoming requests on the specified network address and port number, and then executes the callback function whenever a request is received. It returns the server instance.

* @param {(req: http.IncomingMessage) => string} options.loggerGetIP - use custom logic to get IP, either from headers or directly
* @param {string} options.bindingAddress - hostname for proxy to bind to
* @param {number} options.port - port for proxy to listen to
* @param {number|null} options.crossDomainPort - crossDomain port to simulate cross origin requests. set to null
* to disable using this. highly not recommended to disable this because it breaks sites that check for the origin header
* @param {boolean} options.dontListen - avoid calling http.listen() if you need to use sticky-session to load balance
* @param {http.ServerOptions} options.ssl - set to null to disable ssl
* @param {(req: http.IncomingMessage) => RammerheadServerInfo} options.getServerInfo - force hammerhead to rewrite using specified
* server info (server info includes hostname, port, and protocol). Useful for a reverse proxy setup like nginx where you
* need to rewrite the hostname/port/protocol

const http = require("http");

const server = http.createServer((req, res) => {
  res.statusCode = 200;
  res.setHeader("Content-Type", "text/plain");
  res.end("Hello, World!\n");
});

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

In this example, a simple HTTP server is created using http.createServer(). The server is then set to listen for incoming requests on port 3000 using server.listen().
