Nodemon crashes when trying to use es6 modules but works well with es5

Question

I am trying to run a server using es6 modules but crashes every time I do it and works whenever I use it with es5error message

I have babel installed and have "preset": ["env"] in my .babelrc file but whenever I run it, I have a "syntax error: Invalid or unexpected token". And this is not on one particular project, this is the third project where am experiencing this

import http from 'http';
import express from 'express';
import logger from 'morgan';
import bodyParser from 'body-parser';

// setting up express application
const app = express();

const hostName = '127.0.0.1';
const port = 3000;
const server = http.createServer(app);

// logs request to the console
app.use(logger('dev'))

// Parse incoming data requests
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({
    extended: false
}));

// making a request to the server
app.get('*', (req, res) => res.status(200).send({
    message: 'Welcome to the default API route',
}));

server.listen(port, hostName, () => {
    console.log(`Server running at http://${hostName}:${port}/`);
});

it supposed to bring out "Welcome to the default API route" to the console but instead, it is an error message. And if the repo is needed, i will gladly supply it

ES6 is not yet supported in the Node runtime by default. You can integrate it like this:

1. npm i esm && npm i -D nodemon

2. In your package.json, add this to scripts:

"start": "nodemon -r esm index.js"

(make sure the index.js part of the script matches the name of your server entry point file)

3. Run npm start
