Error in mongodb export in node,js

Question

I was trying to connect mongodb using node.js. I stumbled on a problem. I am getting require(...).pure is not a function error . I tried to use the exact code from this site "https://mongodb.github.io/node-mongodb-native/api-generated/collection.html" My code is given below.

var Db = require('mongodb').Db,
MongoClient = require('mongodb').MongoClient,
Server = require('mongodb').Server,
ReplSetServers = require('mongodb').ReplSetServers,
ObjectID = require('mongodb').ObjectID,
Binary = require('mongodb').Binary,
GridStore = require('mongodb').GridStore,
Grid = require('mongodb').Grid,
Code = require('mongodb').Code,
BSON = require('mongodb').pure().BSON,
assert = require('assert');

var uri = "mongodb://sa:psvitagamer5@cluster0-shard-00-00-
 tpfog.mongodb.net:27017,cluster0-shard-00-01-
  tpfog.mongodb.net:27017,cluster0-shard-00-02-
  tpfog.mongodb.net:27017/myNodeDb?ssl=true&replicaSet=Cluster0-shard-
  0&authSource=admin";


 MongoClient.connect(uri, function(err, db) {

   var collection = db.collection("userCollection");

    collection.insert({hello:'world_no_safe'});

   // Wait for a second before finishing up, to ensure we have written 
     the item to disk
   setTimeout(function() {

  // Fetch the document
   collection.findOne({hello:'world_no_safe'}, function(err, item) {
      assert.equal(null, err);
      assert.equal('world_no_safe', item.hello);
      db.close();
   })
   }, 100);
  //db.close();
});

Please let me know your suggestions.

Out of topic but I suggest you to use mongoose

That documentation is not well written nor tested, pure() is in mongodb-core module

You should install mongodb-core and use:

BSON = require('mongodb-core').BSON;

As I can see you (and that documentation) are not using BSON at all, you should remove that.

require('mongodb-core').BSON works but require('mongodb-core').BSON.pure().BSON gives the same error . Is 'require('mongodb-core').BSON' only required?

Like I said in second point, you are not using any BSON functions, just remove that require line and you should be ok
