app.set('view engine', 'ejs');
var db;
app.listen(8080, function () {
console.log('listening on 8080');
});
app.get('/', function (req, response) {
response.sendFile(__dirname + '/index.html');
});
app.get('/write', function (req, response) {
response.sendFile(__dirname + '/write.html');

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
