Node Js Ctrl C Doesnt Stop Server After Starting Server With Npm Start

If you've ever encountered the issue where Ctrl+C doesn't stop your Node.js server after starting it with `npm start`, you're not alone. This common problem can be frustrating, but fear not - there are several possible solutions to help you gracefully shut down your server.

One potential reason why Ctrl+C may not be stopping your server is that the script executed by `npm start` ignores interrupt signals. To address this, you can modify the Node.js script to listen for interrupts and handle them appropriately.

Here's how you can update your `package.json` file to address this issue:

"scripts": {
  "start": "node server.js"
}

In your `server.js` file, you can add an event listener to gracefully handle the interrupt signal:

process.on('SIGINT', function() {
  console.log("Received interrupt signal. Shutting down server...");
  // Add any additional cleanup or shutdown logic here
  process.exit(0);
});

By adding this code snippet to your Node.js server script, you are explicitly telling Node.js to handle the interrupt signal (Ctrl+C) and perform a clean shutdown when it is received.

Another possible reason for this issue could be related to the specific behavior of the operating system or terminal you are using. Certain environments may require additional steps to properly handle interrupt signals.

If modifying the script and handling interrupt signals does not resolve the problem, you can try using alternative commands to stop the server. For example, you can use `Task Manager` (Windows) or `kill` command (Unix-based systems) to forcefully terminate the Node.js process.

To find the process ID (PID) of your Node.js server, you can use the following command on Unix-based systems:

ps aux | grep node

Once you have identified the PID of the Node.js process, you can use the `kill` command to stop it:

kill -9 PID

Keep in mind that using the `kill` command with signal `9` (`SIGKILL`) will abruptly terminate the process without allowing it to perform any cleanup operations.

In conclusion, if Ctrl+C isn't stopping your Node.js server after starting it with `npm start`, you can address this issue by modifying your Node.js script to handle interrupt signals, considering the behavior of your operating system or terminal, and using alternative commands to stop the server if necessary. With these troubleshooting steps, you should be able to successfully stop your Node.js server and continue working on your projects without interruption.
