NodeJS express - What is the difference and correct way of creating a basic server

Question

What is the difference and what is the most correct and latest way when creating a server with nodejs express?

const express = require('express');
const app = express();

app.listen(process.env.PORT || 3000, function () {
console.log('server running')
});

and the second way

const express = require('express');
const app = express();
const server = require('http').createServer(app)

server.listen(process.env.PORT || 3000, function () {
console.log('server running')
});

Answer 1

In terms of correctness, there is no difference, express basically does what you're doing in the second example when app.listen is called.
