...The simple app shown above, adds a graceful shutdown period of 5 seconds after which the hook, which takes care of closing the server with the help of our shutdown functionality, gets triggered. Upon sending a SIGINT or SIGTERM signal, the user can see that a grace period of 5 seconds after which a waiting async operation of 3 seconds takes place, and only then the message 'shutdown after graceful period' indicate the closing of the server will be displayed. The app also showcases the functionality of the "getHealthHandler". Upon requesting localhost:3000/health, the healthTest will return true and the message 'everything is great' indicating a positive health check should be displayed.
