// Callback function for checking connecting or error
SERVER.on("error", error => {
throw new Error(`[Server]::ERROR:${error.message}`);
});

* Ex: Like if the app is unable to connect to database then the app will shutdown.

// I just caught an unhandled promise rejection,

// let throw and let him handle that

process.on("uncaughtException", error => {
// I just received an error that was never handled,
// time to handle it and then decide whether a restart is needed
