Error de mongoose en nodejs

[Diesan Romero]

Intento conectarme a mongodb desde nodejs usando mongoose y no se por que no me deja

Este es mi archivo del servidor en express:

Código (javascript) [Seleccionar] Expandir


const express = require('express');
const helmet = require('helmet');
const bodyParser = require('body-parser')
const compression = require('compression');
const app = express();
const port = 80;
const db = require('./config/database');
db.connect();

//use
app.use(bodyParser.text({ type: 'text/html' }));
app.use(helmet());
app.use(compression());

//Peticiones GET
app.get('/', function(req,res){
  res.render('index');
})

//Puerto
app.listen(port, (req, res) => {
  console.log("listening...");
});




este es mi archivo de configuracion de la base de datos con mongoose:

Código (javascript) [Seleccionar] Expandir


const mongoose = require('mongoose');
const dbName = 'places';

module.exports = {
  connect: ()=> mongoose.connect('mongodb://localhost'+dbName),
  dbName,
  connection: ()=>{
    if(mongoose.connection)
      return mongoose.connection;
    return this.connect();
  }
}



y este es el error que me sale en consola que no logro entender:

Me dijeron que usara MongoClient algo asi:

Código (javascript) [Seleccionar] Expandir


mongoose.connect('mongodb://localhost'+dbName,  { useMongoClient: true })

no entiendo que significa el objeto ese, alguien sabe?
