How to quit a Node.js app gracefully?

To quit a Node.js app gracefully, we can listen for the SIGINT event and call process.exit when it’s triggered.

For instance, we write

process.on('SIGINT', () => {
  process.exit();
})

to listen to the SIGINT event by calling process.on with 'SIGINT'.

In the event handler callback, we call process.exit without an an exit code to exit the app gracefully.
