When deploying a new version of your application, the previous version receives a termination signal before shutting down. This allows your application to properly close database connections and stop other services.

The termination signal SIGTERM is sent to your application. You can handle this signal in your code as follows:

process.on('SIGTERM', () => {
  // This log appears on the Stackhero dashboard in the "logs" tab
  console.info('SIGTERM signal received.');

  // Close open database connections or other services here
  // ...
});
