Here you have imported the module but you haven't configured the database.
const MongoClient = require('mongodb').MongoClient;
var mongoclient = new MongoClient(new Server("localhost", 27017), {native_parser: true});
var db = mongoclient.db("COLLECTION_NAME");
For more information check here https://mongodb.github.io/node-mongodb-native/api-generated/mongoclient.html
