const express = require('express');
const app = express();
app.use(express.urlencoded({
    extended: true
}));
const MongoClient = require('mongodb').MongoClient;
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');
});


app.get('/list', function (req,response) {
    db.collection('post').find().toArray(function(err, results){
        console.log(results);

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
