I want to deploy a small node.js app on a PLESK-ONYX server - on which Phusion_Passenger / 5.3.5 is also running!

The following happens:

This works here:

var express = require ('express');

var bodyParser = require ('body-parser');

That does not work:

import express from 'express';

import bodyParser from 'body-parser';

The following error then occurs:

The Phusion Passenger application server tried to start the web application through a Passenger-internal helper tool called the "wrapper". But Passenger was unable to execute that helper tool because it encountered an internal error.

The stdout/stderr output of the subprocess so far is:

/var/www/vhosts/hosting13.netcup.net/mem3-s3.hxxx-3.de/index.js:2

import express from 'express';

    ^^^^^^^

How can one solve it?

Where is the problem?

Thank you for your help in advance!

Best regards

Hello, I have new findings in the meantime ...

my problem seems to be - that the highest-available node.js version in PLESK at the moment is 12.4!

In PLESK - i must start the node.js-App with a server.js-File - like this:

const app = require('./index.mjs');
const http = require('http');

http.createServer(app).listen(process.env.PORT);

My node.js-Version is V.12.4 so i must use esm like this:

require = require("esm")(module/*, options*/)
module.exports = require("./index.js")

How can i combine the 2 files in the right way?

Thanks a lot for your help!

Here is the content of "package.json":

{
  "name": "mb-test-1",
  "version": "1.0.0",
  "description": "",
  "main": "index.mjs",
  "type": "module",
  "scripts": {
    "start": "nodemon -r esm index.mjs"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "body-parser": "^1.19.0",
    "cors": "^2.8.5",
    "dotenv":"^8.2.0",
    "esm":"^3.2.25",
    "express":"^4.17.1",
    "mongoose":"^5.9.29",
    "nodemon":"^2.0.7"
  }

}

But unfortunately I haven't found yet - where in PLESK the start command for node.js can be edited!

Best regards

Markus

for using import from you should change type in package.json to module so add this code to the package.json

"type": "module"

Note: but export file is different between commonjs and module.

by default type is commonjs , check this article

you can also using babel module, update scripts in package.json like this

  "scripts": {
    "build": "rimraf dist/ && babel ./ --out-dir dist/ --ignore ./node_modules,./.babelrc,./package.json,./npm-debug.log --copy-files",
    "start": "npm run build && node dist/app.js"
  }

after that for running project

npm start
