Node index js ошибка - Ремонт и установка крупной бытовой техники

I have an app in NodeJS with Apollo Server, Graphql, etc. I want to use PM2 to have my index like a service so, when I close the console It dont stop.

When I execute npm start the server starts perfect. This is my start in package.json

«start»: «nodemon ./index.js —exec babel-node -e js»,

If I execute node index.js then this error appears.

/home/ubuntu/react/desafio/servidor/index.js:1
import express from 'express';

this is my index.js code

 import express from 'express';
    import { ApolloServer, AuthenticationError } from 'apollo-server-express';
    import { typeDefs } from './data/schema';
    import { resolvers } from './data/resolvers';
    import jwt from 'jsonwebtoken';
    import dotenv from 'dotenv';
    import db from "./models";

    dotenv.config({path:'variables.env'});

    const cors = require('cors');
    const app = express();
    // enable cors

     // app.use(cors());
    const addToken = async (req) =>{

    }
    const server=  new ApolloServer({
        typeDefs,
        resolvers
    });

    server.applyMiddleware({app});
    app.listen({port:9000},()=> console.log(`Server Corriendo http://localhost:9000${server.graphqlPath}`));

what Im doing wrong?

index.js source code if it helps.

const http = require('http');
const hostname = 'localhost';
const port = 3000;

const server = http.createServer((req, res) => {

First i am create

Code folder in c: drive
Then navigate Code in cmd

Create package.json file with following code

var express = require('express')
  , app = express.createServer();

app.get('/', function(req, res) {
  res.send('hello world');
});

app.listen(3000)

Then install npm using npm install in code folder.
Then code have new folder node_modules and package.json file. Inside node_modules folder express folder is available inside 2 folder is available lib and node_modules and many more files is there. Now i am confused to run my first project.

Here is a «Hello World» example, extracted from the Express guide, suggested above:

var express = require('express');
var app = express(); // here I use the express() method, instead of the createServer()

app.get('/', function(req, res){
  res.send('Hello World');
});

var server = app.listen(3000, function() {
  console.log('Listening on port %d', server.address().port);
});

You will want to put the code inside a file called app.js instead of package.json. Then you should be able to just run the app using node app.js. The package.json can be created with npm init and npm --save express.

Or you can use the express-generator tool as described in the Express guide.

var express = require('express');
var app = express();
var http = require('http');
app.set('port', process.env.PORT || 3000);
app.get('/', function(req, res){
   res.send('Hello World');
});

http.createServer(app).listen(app.get('port'), function(){
  console.log("Express server listening on port " + app.get('port'));
});
