nodemon stopping doesn't stop the process in ubuntu

I'm using nodemon in my nodejs app to auto restart when changes apply. But when I stop nodemon using 'Ctrl + C' in ubuntu environment, doesn't stop nodejs. I have to search the process that's running from the port and have to kill manually using kill -9 . How can I fix this?

Quick and dirty solution 

process.on('SIGTERM', stopHandler);
process.on('SIGINT', stopHandler);
process.on('SIGHUP', stopHandler);
function stopHandler() {
  console.log('Stopped forcefully');
  process.exit(0);
}

Right solution

Implementing Graceful Shutdown is a best practise. At this example, I should only stop the server. If the server will stop longer than 2s, then the process will terminate with exitcode 1.

process.on('SIGTERM', stopHandler);
process.on('SIGINT', stopHandler);
process.on('SIGHUP', stopHandler);
async function stopHandler() {
  console.log('Stopping...');

  const timeoutId = setTimeout(() => {
    process.exit(1);
    console.error('Stopped forcefully, not all connection was closed');
  }, 2000);

  try {
    await server.stop();
    clearTimeout(timeoutId);
  } catch (error) {
    console.error(error, 'Error during stop.');
    process.exit(1);
  }
}
