I have this Node.js application that utilizes MongoDb:
const MongoClient = require('mongodb').MongoClient;
const demoPerson = { name:'Jane', lastName:'Doe' };
const findKey = { name: 'Jane' };
MongoClient.connect('mongodb://127.0.0.1:27017/demo', { useNewUrlParser: true }, function(err, client) {
const db = client.db('demo');
if(err) throw err;
console.log('Connection successful');
//console.log(db);
const collection = db.collection('people');
collection.insert(demoPerson, function(err, docs) {
console.log('Inserted:', docs[0]);
console.log('ID:', demoPerson._id);
collection.find(findKey).toArray(function(err, results) {
console.log('Found the following results:', results);
collection.remove(findKey, function(err, results) {
console.log('Deleted person successfully');
db.close();
});
});
});
});
However, running it gives me this error message:
TypeError: db.close is not a function
I am having trouble figuring out why it doesn't work. Can someone assist me?
