  //With this code, you can now gracefully exit the server by pressing Ctrl + C in the terminal where the server is running. The signal handler captures the SIGINT signal sent when Ctrl + C is pressed and initiates the server shutdown process. The server will close existing connections and then stop before the Node.js process exits.
