How to solve insertOne is not a function problem

var MongoClient = require('mongodb').MongoClient;

var url = 'mongodb://localhost:27017/';

MongoClient.connect(url, {useNewUrlParser: true}, function(err, db){

  if(err) throw err;

  var dbo = db.db('mydb');

  var myObj = [{name: 'Company Inc', address: 'Highway 37'}];
  dbo.createCollection('Customers').insertone(myObj, function(err, res){

    if(err) throw err;
    console.log('1 document inserted!');
    db.close();
  });
});

My code is not working, the error is insertOne is not a function. My mongoDB shell version is 3.4.18 and npm installed mongodb module is 3.1.10.

Try inserting your record without creating the collection, as insertOne will automatically create the collection if it does not exist.

var MongoClient = require('mongodb').MongoClient;
var url = 'mongodb://localhost:27017/';
MongoClient.connect(url, {useNewUrlParser: true}, function(err, db){
  if(err) throw err;
  var dbo = db.db('mydb');
  var myObj = [{name: 'Company Inc', address: 'Highway 37'}];
  var collection = db.collection('Customers');
  collection.insertOne(myObj, function(err, res){
    if(err) throw err;
    console.log('1 document inserted!');
    db.close();
  });
});
