Meteor - Uncaught Error: Cannot find module 'mongodb'

I'm trying to establish a connection between my Meteor application and my MongoDB Atlas database.

I have the following bit of JavaScript:

  var MongoClient = require('mongodb').MongoClient, format = require('util').format;                  
MongoClient.connect('<MyMongoURL>', function (err, db) {
if (err) {
    throw err;
} else {
    console.log("successfully connected to the database");

    db.collection('largeTreeMap', function(err, docs) {
    // Check for error
    if(err) return console.log(err);
    // Walk through the cursor
    docs.find().each(function(err, doc) {
        // Check for error
        if(err) return console.err;
        // Log document
        console.log(doc);
    })
});

}
db.close();      });

I added this to a blank JS document called test.js and upon running 

node test.js

In my command line it returned the success message and data:

Success

So now that I know the connection can be established I added the code to my Meteor project. I created a basic button and onClick the connection to MongoDB should completed.

However, instead I receive the following console error:

Error

I understand from reading various Stack questions that this is a result of not running npm install mongodb in the project directory. However, I have tried doing this and the terminal returns:

Error 2

Does any body know why the MongoDB is failing to install and preventing me from connecting to MongoDB in my application?

Any help would be much appreciated,

Many thanks,

G

You're trying to connect to the Mongo instance from the client, which is probably not what you want.

The mongodb npm package supports only Node.js, not JavaScript in the browser, as you can see from this line in its package.json

"engines": {
  "node": ">=0.10.3"
},

In the case that worked, you are running it with Node.

What you probably want to do is to set the MONGO_URL environment variable to the Mongo Atlas instance, and leave the implementation of connecting / updating to Meteor itself.
