Why JS async function shows neither print nor error?


My code

const mongoose = require('mongoose');
const Tutorial = require('./models/Tutorial');

async function createTutorial() {
  try {
    console.log('guy Incognito');
    const doc = await Tutorial.create({ title: 'bill ', body: 'Bill Russel was great player!' });
  } catch (err) {


In models/Tutorials

const mongoose = require('mongoose');

const TutorialSchema = new mongoose.Schema({
  title: String,
  body: String,
  createdAt: {
    type: Date,
    default: Date.now,

module.exports = mongoose.model('Tutorial', TutorialSchema);

When I run my code from terminal,

node index.js


guy Incognito

It seems that promise is not resolved.. Why?


You probably don’t have a correct connection to your database. If I take your exact code, everything is working fine with a correct connection and behave as described in your question with no connection.

To create a connection call mongoose.connect('mongodb://<db_uri>', {useNewUrlParser: true}); somewhere in your app.

To understand why your code didn’t throw any error and you had no log, you can read more about how mongoose handle connection here
