node process doesn't exit after firebase once

Question

Using node.js with the npm firebase.

var firebase = require('firebase'); var blahFirebase = new firebase('https://myfirebase.firebaseIO.com/blah'); blahFirebase.once('value', function (snapshot) {     // }); 

Why does node not exit when it is done reading the data?

Answer 1

In the new Firebase API you should use firebase.app.App.delete() to free the resources its holding. For example:

var app = firebase.initializeApp({ ... }); var db = firebase.database();  // Do something  app.delete(); // Release resources 

Do not use process.exit() since it will stop the entire process (which is not what you would usually want).

Answer 2

My case is using firebase admin,

const  admin = require('firebase-admin'); 

and I can end node process by

return admin.app().delete();
