Rest api - connect to db and server - URL string parser is deprecated

Question

I'm trying to create a simple rest API with a mongodb.

I have a server.js file

const express = require('express');
const mongoose = require('mongoose');
const bodyParser = require('body-Parser');

const app = express();

app.use(bodyParser.json());

const db = require('./config/keys').mongoURI;

mongoose
    .connect('mongodb://test:test123@ds241012.mlab.com:41012/mern_shopping')
    .then(() => console.log('DB Connected'))
    .catch(err => console.log(err));

const port = process.env.PORT || 5000;

app.listen(port, () => console.log('Server started'));

I'm using nodemon

When I run npm run server I get the following error

(node:65209) DeprecationWarning: current URL string parser is deprecated, and will be removed in a future version. To use the new parser, pass option { useNewUrlParser: true } to MongoClient.connect.

then I got error in console

failed to connect to server

How do I fix this

Update

With {useNewUrlParser: true} the server starts but if I touch the server.js file I get this.

Server started
{ MongoNetworkError: failed to connect to server [ds241012.mlab.com:41012] on first connect [MongoNetworkError: connection 0 to ds241012.mlab.com:41012 timed out]

DeprecationWarning it is not error. It's just a warning. I left your url connection link: newparser. `connect('mongodb://@.mlab.com:41012/mern_shopping',{useNewUrlParser: true})`. — Chance, Sep 04 '18 at 13:18
Please hide your access credentials.. The connection problem is probably the port of the expression in use. As you can see in the image I used your access data to connect successfully.

I did not understand, in my first cometary I already added the `{useNewUrlParser: true}`. @Anouar Kacem — Chance, Sep 04 '18 at 13:40
@RRachel, your code works fine in my local system. Can you please post the complete stack trace. — Sridhar, Sep 04 '18 at 13:49
