Access control is not enabled for the database

Question

I am creating an sample library app in nodejs+express+mongodb. when I run the gulp serve command the server start perfectly. when I goto specific mongodb page then it giving error insertMany is not a function.

var express = require('express');
var adminRouter = express.Router();
var mongodb = require('mongodb').MongoClient;
var books = [
   {
      title: 'world',
      genre: 'Lorem Ipsum text changing occured',
      author: 'Rakesh',
      read: false
   },
   {
      title: 'Make of the world',
      genre: 'Digital India towards occured',
      author: 'Jumanji',
      read: false
   }
];

var router = function (nav) {
   adminRouter.route('/addBooks')
      .get(function (req, res) {
         var url = 'mongodb://127.0.0.1:27017/admin';
         mongodb.connect(url, function (err, db) {
            var collections = db.collections('books');
            collections.insertMany(books, 
               function (err, results) {
                  res.send(results);
                  db.close();
               }
            );
         });
      });

   return adminRouter;
};

module.exports = router;

Mongo cmd screenshots insertMany cmd not working

Answer 1

There is a typo in syntax in line var collections = db.collections('books'); . The node mongo driver could only interpret a db.collection() function not db.collections() which actually is syntactically wrong.

Use db.collection('books') instead of db.collections('books') , this should fix the bug. Try it and let me know
