below simple example how using firebase:

let firebase = require('firebase'); firebase.initializeapp({   serviceaccount: './config/firebase.json',   databaseurl: 'https://thenameofhedatabase.firebaseio.com' });  let db = firebase.database(); ... ...

the point after code execution db object holds node.js session. not want call process.exit(0). so, right way close or dispose db object of firebase?

this has been fixed in version 3.4.1 of javascript sdk.

firebase.database().gooffline() releases database node.js process can exit.
