Can't connect to MongoDB via nodejs

Question

I'm trying to create a web page that will pull data from MongoDB server.

I tried to use node js driver, but it regularly throwing this error:

this is my mongo.js script:

require(['mongodb'], function(mongodb) {
    mongodb.MongoClient.connect("mongodb://x.x.x.x:27017", function (err, client) {
        console.log("Connected successfully to server");
    });
});

The method connect is not working for me (it throws the error). I tried to connect in a many different ways.

I placed it in the bottom of the html body.

How can I solve this problem?

Thanks!

There is nothing called mongodb in node, in order to use mongodb in node, you have to use middlewares like mongoclient or mongoose that connect to mongo db.

Syntax :

require('mongodb').MongoClient.connect("mongodb://localhost:27017/mydb",function(err,db){
   if(err)
     throw err;
   console.log("connected successfully");
   db.close();
});

You are using square bracket, that might not including mongodb else if you are sure that your syntax is right, you can check it by following code

let mon = require(['mongodb']);
console.log(mon)

If above two lines doesnot give error, then please ping me I will see more over it but primarily I can see the error while you are calling require(['mongodb']).

also, first check that wether you have included the mongo.js file correctly as resource.js is sending **error 404** – Rnayak Aug 05 '18 at 07:58
I tried to use `require` without brackets, but it throws this error: `Module name "MongoDB" has not been loaded yet for context: _. Use require([])`, I also tried mongoose but it gave the same problem. – Roi Amiel Aug 05 '18 at 08:00
before requiring it, have you installed **mongoclient** using npm? – Rnayak Aug 05 '18 at 08:02
`var MongoClient = require('mongodb').MongoClient; var url = "mongodb://localhost:27017/mydb"; MongoClient.connect(url, function(err, db) { if (err) throw err; console.log("Database created!"); db.close(); });` run the following code and share the output you are getting. – Rnayak Aug 05 '18 at 08:19
Module name "mongodb" has not been loaded yet for context: _. Use require([]) – Roi Amiel Aug 05 '18 at 08:27
it seems like it can't find some mongodb.js file – Roi Amiel Aug 05 '18 at 08:29

use this one

    import MongoClient from 'MongoDB;
//Create a database named "mydb":
var url = "mongodb://localhost:27017/mydb";

MongoClient.connect(url, function(err, db) {
  if (err) throw err;
  console.log("Database created!");
  db.close();
});
